NAME

HTTP::WebTest - Testing static and dynamic web content

CONTENTS

SYNOPSIS



    use HTTP::WebTest;

    my $webtest = new HTTP::WebTest;

    # run test from file
    $webtest->run_wtscript(script.wt);

    # or (to pass test parameters as method arguments)
    $webtest->run_tests($tests);



DESCRIPTION

    Introduction

This module runs tests on remote URLs containing Perl/JSP/HTML/JavaScript/etc. and generates a detailed test report. This module can be used as-is or its functionality can be extended using plugins. Plugins can define test types and provide additional report capabilities. This module comes with a set of default plugins but can be easily extended with third party plugins.

The wt script is provided for running HTTP::WebTest from the command line.

The test specifications can be read from a parameter file in wtscript format or input as method arguments. The test results can be displayed on the terminal, directed to a file, stored in a scalar variable. The test results can also be emailed. The report can be modified and extended using report plugins.

Each URL/web file is tested by fetching it from the web server using a local instance of an HTTP user agent. The basic test is simply whether or not the fetch was successful. You may also test using literal strings or regular expressions that are either required to exist or forbidden to exist in the fetched page. You may also specify tests for the minimum and maximum number of bytes in the returned page. You may also specify tests for the minimum and maximum web server response time.

Data flow for HTTP::WebTest:

                                      ------------



    Getting started

This module has complex functionality, but using it to run simple tests is simple. Create a file of test parameters in the wtscript format and use the wt program to process the file using the command wt filename. The only required parameters are test_name and url.

This document describes:
o How tests can be specified. See section TEST SPECIFICATION.
o All test parameters supported by core HTTP::WebTest plugins. See section TEST PARAMETERS.
See perldoc wt for documentation on the wt program.

Other useful documentation is:
o perldoc HTTP::WebTest::Cookbook - examples of wtscript files and examples of HTTP::WebTest API usage.
o perldoc HTTP::WebTest::API - full documentaion on API of HTTP::WebTest.
o perldoc HTTP::WebTest::Plugins - for developers of HTTP::WebTest plugins.

TEST SPECIFICATION

The test specifications can be read from a parameter file (in the wtscript format described below) or passed as method arguments as an array of hashes.

    Running HTTP::WebTest using a parameter file

HTTP::WebTest can read test specification from file in format called as wtscript.

Tests defined by wtscript file can be run either using Perl API of HTTP::WebTest



    use HTTP::WebTest;

    my $webtest = new HTTP::WebTest;
    $webtest->run_wtscript(script.wt);



or by using program wt supplied with this module.

If you are running dozens of tests, you may want to divide them into several parameter files. This will organize the tests and reduce the size of the output and e-mail messages. However, cookies passed to or received from the web server(s) are not shared between tests in different parameter files.

File format

The wtscript file is a text file containing global parameters and test blocks containing test block parameters. A test block begins with a test_name parameter and ends with an end_test directive. The order of the parameters and test blocks is arbitrary.

Test block parameters MUST occur between a test_name parameter and an end_test directive. (Test block parameters affect only an individual test.) Global parameters must NOT occur between a test_name parameter and an end_test directive. (This requirement does not apply to certain parameters that are both global and test block parameters.)

The following lines are ignored:
o lines consisting of nothing but white space (blanks or tabs)
o lines beginning with a number sign (#)
o lines beginning with white space (blanks or tabs) followed by a number sign
Parameters are either scalar (single-valued) or lists (single-valued, multi-valued or nested).

You can specify scalar parameters using forms such as:



    name=value
    name =
           value
    name = value



You can specify list parameters using forms such as:



    name = ( first value
             second value )
    name=( first value => second value
           third value => fourth value
         )
    name = ( first value => second value )
    name = (
             first value
             second value )
    name= (
             first value
             second value
             third value => fourth value
          )
    name =
           ( first value
             second value )
    name = (
             first value
             second value
           )



Lists can be nested. For example:



    name = ( ( first value
               second value ) )

    name = ( third value
             ( fourth value => fifth value ) )

    name = (
             ( first value
               second value )
             third value
             ( fourth value => fifth value )
           )



You can specify a null (placeholder) value using ’’ or ". Within single or double quotes, the usual Perl string quoting rules apply. Thus, single quotes mean that all enclosed characters are interpreted literally: ’\n’ is backslash-n rather than a newline character. Double quotes mean that Perl metasymbols are interpreted: \n\t is a newline and a tab. Double quoted strings can also contain Perl variables that will be evaluated by Perl. For example, if the variable $myvar contains the string ’foobar’, $myvar" will be replaced by foobar at runtime. Perl variables can be defined by plugin modules or in code sections in the parameter file as described below.

It is also possible to specify a Perl expression in place of a scalar value, one of a list parameter’s values or an entire list. Curly brackets are used to denote Perl code inside wtscript files. HTTP::WebTest compiles this Perl code as anonymous subroutines which are called when values of corresponding test parameters are required. When these subroutines are called HTTP::WebTest object is passed to them as the first argument.

Some examples of syntax:



    # scalar value
    name = { 1 + 1 }

    # element of a list
    name = (
             first value
             { "second " . "value" }
           )

    # entire list (must be a reference to an array)
    name = { [ a => b, c => d ] }

    # accessing HTTP::WebTest object
    name = { my $webtest = shift; ..... }



Examples of wtscript files

The parameters below specify tests. The tests specified by the text_forbid parameter apply to both the MyCompany home page and the Yahoo home page tests. Hence, if either returned page contains one of the case-insensitive strings in text_forbid, the test fails. If any test fails or the fetch of the URL fails, an e-mail will be sent to tester@mycompany.com.



    apache_exec = /usr/sbin/apache
    ignore_case = yes
    mail = errors
    mail_addresses = ( tester@mycompany.com )
    mail_server = mailhost.mycompany.com
    text_forbid = ( Premature end of script headers
                    an error occurred while processing this directive
                  )

    test_name = MyCompany home page (static)
        file_path = ( raycosoft_home.html => . )
        text_require = (
            <a href="/dept/peopledev/new_employee/"><font color="#0033cc">
            <a href="https://www.raycosoft.com/"><font color=
                       )
    end_test

    test_name = Yahoo home page
        url = www.yahoo.com
        text_require = ( <a href=r/qt>Quotations</a>...<br> )
        min_bytes = 13000
        max_bytes = 99000
        min_rtime = 0.010
        max_rtime = 30.0
    end_test



    Calling HTTP::WebTest from a Perl program

If you are using the Perl API of HTTP::WebTest, the test parameters can be defined as an array of hashes.

Each hash in the array defines tests for one URL. Keys in the hashes are test parameter names and values in hashes are values of test parameters. Optional global test parameters can be passed in a hash passed as the second argument.

Subroutine references can be specified instead of test parameter values. Referenced subroutines are called during test run when values of corresponding test parameters are required. These subroutines are called in an object-oriented fashion, so the HTTP::WebTest object is passed as the first argument.

Tests can be run as



    use HTTP::WebTest;

    my $webtest = new HTTP::WebTest;
    $webtest->run_tests(
                        [ # test 1
                          { param1 => value1,
                            param2 => value2 },
                          # test 2
                          { param1 => value1,
                            param2 => value2 },
                        ],
                        { global_param1 => value1,
                          global_param2 => value2 }
                       );



Example

This Perl script tests Yahoo home page and sends full test report to tester@mycompany.com.



    use HTTP::WebTest;

    my $tests = [
                 { test_name    => Yahoo home page,
                   url          => http://www.yahoo.com,
                   text_require => [ <a href=r/qt>Quotations</a>...<br> ],
                   min_bytes    => 13000,
                   max_bytes    => 99000,
                 }
                ];

    my $params = { mail_server    => mailhost.mycompany.com,
                   mail_addresses => [ tester@mycompany.com ],
                   mail           => all,
                   ignore_case    => yes,
                 };

    my $webtest = new HTTP::WebTest;
    $webtest->run_tests($tests, $params);



PLUGIN MODULES

    Core plugin modules

HTTP::WebTest is implemented in a modular structure that allows programmers to easily add modules to run additional tests or define additional simple tests without writing a module. HTTP::WebTest provides a number of core plugin modules which are loaded by default:
HTTP::WebTest::Plugin::ContentSizeTest This plugin checks the size of the fetched web page.
HTTP::WebTest::Plugin::Cookies This plugin controls sending and receiving cookies.
HTTP::WebTest::Plugin::DefaultReport This plugin manages the test report.
HTTP::WebTest::Plugin::Loader This plugin supports adding external plugin modules.
HTTP::WebTest::Plugin::ResponseTimeTest This plugin tests the response times of the web server.
HTTP::WebTest::Plugin::SetRequest This plugin initializes the HTTP requests.
HTTP::WebTest::Plugin::StatusTest This plugin checks the status of the HTTP responses.
HTTP::WebTest::Plugin::TextMatchTest This plugin tests whether the content of the HTTP response matches or doesn’t match selected text or regular expressions.
Information about test parameters supported by core plugins is summarized below in the section TEST PARAMETERS.

    Other plugin modules bundled with HTTP::WebTest

Following plugin modules come with HTTP::WebTest but they are not loaded by default. To use such plugin module load it using global test parameter plugins.
HTTP::WebTest::Plugin::Click This plugin supports using names of links and buttons on HTML pages to build additional tests.
HTTP::WebTest::Plugin::Delay This plugin module allows the user to specify pauses in the test sequence.
HTTP::WebTest::Plugin::HarnessReport This report plugin can generate test reports that are compatible with Test::Harness.
HTTP::WebTest::Plugin::Hooks This plugin allows the user to define callback parameters that are evaluated at runtime. This allows the user to define additional tests without writing a plugin module.
Information about test parameters supported by add-on plugin modules is summarized below in section TEST PARAMETERS.

    Plugin modules released separately from HTTP::WebTest

Following additional HTTP::WebTest plugins are avialable separately from CPAN.
HTTP::WebTest::Plugin::Apache This plugin supports testing web files using a local instance of Apache.
HTTP::WebTest::Plugin::TagAttTest This plugin allows to forbid or require tags and/or attributes in a web page.
HTTP::WebTest::Plugin::DateTest Evaluate the age of embedded date strings in response body.
HTTP::WebTest::Plugin::XMLReport Report plugin for HTTP::WebTest, generates output in XML format.

    Writing plugin modules

See perldoc HTTP::WebTest::Plugins for information about writing HTTP::WebTest plugin modules.

ADD-ONS

Besides additional plugins other HTTP::WebTest add-ons are available from CPAN:
HTTP::WebTest::XMLParser Parser of XML representation of wtscript.

TEST PARAMETERS

Most parameters can be used as both global and test block parameters. If you specify such parameter outside a test block, that value is the default value for all test blocks. The global value can be overriden in each test block by specifying the parameter within the test block.

Parameters marked as GLOBAL PARAMETER can be used only as global and cannot be overriden in test blocks.

Parameters marked as NON-CORE PARAMETER are defined in add-on plugin modules which must be loaded explicitly using the parameter plugins.

    accept_cookies

Option to accept cookies from the web server.

These cookies exist only while the program is executing and do not affect subsequent runs. These cookies do not affect your browser or any software other than the test program. These cookies are only accessible to other tests executed during test sequence execution.

See also the <send_cookies> parameter.

Allowed values

yes, no

Default value

yes

    auth

A list which contains two elements: userid/password pair to be used for web page access authorization.

    click_button

NON-CORE PARAMETER from HTTP::WebTest::Plugin::Click

Given name of submit button (i.e. <input type="submit"> tag or <input type="image"> inside of <form> tag) on previously requested HTML page, builds test request to the submitted page.

Note that you still need to pass all form parameters yourself using params test parameter.

Example

See example in HTTP::WebTest::Cookbook.

    click_link

NON-CORE PARAMETER from HTTP::WebTest::Plugin::Click

Given name of link (i.e. <a> tag) on previosly requested HTML page, builds test request to the linked page.

Example

See example in HTTP::WebTest::Cookbook.

    cookie

Synonym to cookies.

It is deprecated parameter and may be removed in future versions of HTTP::WebTest.

    cookies

This is a list parameter that specifies cookies to send to the web server:



    cookies = ( cookie1_spec
                cookie2_spec
                ...
                cookieN_spec )



Currently there are two ways to specify a cookie.
o Named style

A cookie is specified by a set of param => value pairs:



    (
      param => value
      ...
    )



List of all supported param => value pairs:
version => VERSION Version number of cookie spec to use, usually 0.
name => NAME (REQUIRED) Name of cookie. Cannot begin with a $ character.
value => VALUE (REQUIRED) Value of cookie.
path => PATH (REQUIRED) URL path name for which this cookie applies. Must begin with a / character. See also path_spec.
domain => DOMAIN (REQUIRED) Domain for which cookie is valid. Must either contain two periods or be equal to .local.
port => PORT List of allowed port numbers that the cookie may be returned to. If not specified, cookie can be returned to any port. Must be specified using the format N or N, N, ..., N where N is one or more digits.
path_spec => PATH_SPEC Ignored if version is less than 1. Option to ignore the value of path. Default value is 0.
o 1

Use the value of path.

o Ignore the specified value of path.
secure => SECURE Option to require secure protocols for cookie transmission. Default value is 0.
o 1

Use only secure protocols to transmit this cookie.

o Secure protocols are not required for transmission.
maxage => MAXAGE Number of seconds until cookie expires.
discard => DISCARD Option to discard cookie when the program finishes. Default is 0. (The cookie will be discarded regardless of the value of this element.)
o 1

Discard cookie when the program finishes.

o Don’t discard cookie.
rest => NAME_VALUE_LIST Defines additional cookie attributes.

Zero, one or several name/value pairs may be specified. The name parameters are words such as Comment or CommentURL and the value parameters are strings that may contain embedded blanks.

Example (wtscript file):



    cookies = ( ( name   => Cookie1
                  value  => cookie value )

                ( name   => Cookie2
                  value  => cookie value
                  path   => /
                  domain => .company.com ) )

                ( name   => Cookie2
                  value  => cookie value
                  rest   => ( Comment => this is a comment ) )



Example (Perl script):



    my $tests = [
                  ...
                  {
                    test_name => cookie,
                    cookies   => [ [
                                     name  => Cookie1,
                                     value => Value,
                                   ],
                                   [
                                     name  => Cookie2,
                                     value => Value,
                                     path  => /,
                                   ] ],
                    ...
                  }
                  ...
                ]



o Row list style

This style of cookie specification is deprecated and may be removed in future versions of HTTP::WebTest.

Each cookie is specified by following list:



    ( VERSION
      NAME
      VALUE
      PATH
      DOMAIN
      PORT
      PATH_SPEC
      SECURE
      MAXAGE
      DISCARD
      NAME1
      VALUE1
      NAME2
      VALUE2
      ...
    )



Any element not marked below as REQUIRED may be defaulted by specifying a null value or ’’.
o VERSION (REQUIRED)

Version number of cookie spec to use, usually 0.

o NAME (REQUIRED)

Name of cookie. Cannot begin with a $ character.

o VALUE (REQUIRED)

Value of cookie.

o PATH (REQUIRED)

URL path name for which this cookie applies. Must begin with a / character. See also path_spec.

o Don’t discard cookie.

o name/value

Zero, one or several name/value pairs may be specified. The name parameters are words such as Comment or CommentURL and the value parameters are strings that may contain embedded blanks.

An example cookie would look like:



    cookies = ( ( 0
                  WebTest cookie #1
                  cookie value
                  /
                  .mycompany.com
                  
                  0

See RFC 2965 for details (ftp://ftp.isi.edu/in-notes/rfc2965.txt).

    default_report

GLOBAL PARAMETER

This parameter controls whether the default report plugin is used for test report creation. Value yes means that default report plugin will be used, value no means that it will not. It can also be used to disable all output (i.e. if this parameter has value no and no other report plugins are loaded).

Allowed values

yes, no

Default value

yes

    delay

NON-CORE PARAMETER from HTTP::WebTest::Plugin::Delay

Duration of pause (in seconds) before running test.

Allowed values

Any number greater that zero.

    end_test

Allowed values

Any integer greater that zero and greater than min_bytes (if min_bytes is specified).

    max_rtime

Maximum web server response time (seconds) expected.

Allowed values

Any number greater that zero and greater than min_rtime (if min_rtime is specified).

    method

HTTP request method.

See RFC 2616 (HTTP/1.1 protocol).

Allowed values

GET, POST

Default value

GET

    min_bytes

Minimum number of bytes expected in returned page.

Allowed values

Any integer less than max_bytes (if max_bytes is specified).

    min_rtime

Minimum web server response time (seconds) expected.

Allowed values

Any number less than max_rtime (if max_rtime is specified).

    on_finish

NON-CORE PARAMETER from HTTP::WebTest::Plugin::Hooks

The value of this test parameter is ignored. However, it is evaluted before the test sequence is run, so it can be used to run finalization code when the test sequence is finished.

Example

See example in HTTP::WebTest::Cookbook.

    on_request

NON-CORE PARAMETER from HTTP::WebTest::Plugin::Hooks

The value of this test parameter is ignored. However, it is evaluted before the HTTP request is done, so it can be used to do initalization before the request.

    on_response

NON-CORE PARAMETER from HTTP::WebTest::Plugin::Hooks

This is a list parameter which is treated as test result. It is evaluted when the HTTP response for the test request is received.

It can be used to define custom tests without writing new plugins. It can also be used to run some code when the HTTP response for the test request is received.

Allowed values



    ( YESNO1, COMMENT1
      YESNO2, COMMENT2
      ....
      YESNON, COMMENTN )



Here YESNO, COMMENT is a test result. YESNO is either yes if test is successful or no if it is not. COMMENT is a comment associated with this test.

Example

See example in HTTP::WebTest::Cookbook.

    on_start

NON-CORE PARAMETER from HTTP::WebTest::Plugin::Hooks

The value of this test parameter is ignored. However, it is evaluted before the test sequence is run, so it can be used to do initalization before the test sequence run.

Example

See example in HTTP::WebTest::Cookbook.

    output_ref

GLOBAL PARAMETER

A reference to a scalar that accumulates text of test report. If this test parameter is specified then value of test parameter fh_out is ignore.

This parameter can be used only when passing the test parameters as arguments from a calling Perl script.

    params

A list of name/value pairs to be passed as parameters to the URL. (This element is used to test pages that process input from forms.)

If the method key is set to GET, these pairs are URI-escaped and appended to the requested URL.

Example (wtscript file):



    url = http://www.hotmail.com/cgi-bin/hmhome
    params = ( curmbox
               F001 A005
               from
               HotMail )



generates the HTTP request with URI:



    http://www.hotmail.com/cgi-bin/hmhome?curmbox=F001%20A005&from=HotMail



If the method key is set to POST, as long as all values are scalars they are URI-escaped and put into content of the HTTP request. application/x-www-form-urlencoded content type is set for such HTTP request.

If the method key is set to POST, some values may be defined as lists. In this case HTTP::WebTest uses multipart/form-data content type used for Form-based File Upload as specified in RFC 1867. Each parameter with list value is treated as file part specification with the following interpretation:



    ( FILE, FILENAME, HEADER => VALUE... )



where
o FILE

The name of a file to open. This file will be read and its content placed in the request.

o FILENAME

The optional filename to be reported in the request. If it is not specified than basename of FILE is used.

o HEADER => VALUE

Additional optional headers for file part.

Example (wtscript file):



    url = http://www.server.com/upload.pl
    method = post
    params = ( submit => ok
               file   => ( /home/ilya/file.txt, myfile.txt ) )



It generates HTTP request with /home/ilya/file.txt file included and reported under name myfile.txt.

    pauth

A list which contains two elements: userid/password pair to be used for proxy server access authorization.

    plugins

GLOBAL PARAMETER

A list of module names. Loads these modules and registers them as HTTP::WebTest plugins. If the name of the plugin starts with ::, it is prepended with HTTP::WebTest::Plugin. So



    plugins = ( ::Click )



is equal to



    plugins = ( HTTP::WebTest::Plugin::Click )



    proxies

A list of service name/proxy URL pairs that specify proxy servers to use for requests.

Example



    proxies = ( http => http://http_proxy.mycompany.com
                ftp  => http://ftp_proxy.mycompany.com )



    regex_forbid

List of regular expressions that are forbidden to exist in the returned page.

For more information, see perldoc perlre or see Programming Perl, 3rd edition, Chapter 5.

See also the text_forbid and ignore_case parameters.

    regex_require

List of regular expressions that are required to exist in the returned page.

For more information, see perldoc perlre or see Programming Perl, 3rd edition, Chapter 5.

See also the text_require and ignore_case parameters.

    relative_urls

If set to yes than HTTP-WebTest supports relative URLs. See test parameter url for more information.

Allowed values

yes, no

Default value

no

    send_cookies

Option to send cookies to web server. This applies to cookies received from the web server or cookies specified using the cookies test parameter.

This does NOT give the web server(s) access to cookies created with a browser or any user agent software other than this program. The cookies created while this program is running are only accessible to other tests in the same test sequence.

See also the <accept_cookies> parameter.

Allowed values

yes, no

Default value

yes

    show_cookies

Option to display any cookies sent or received.

Allowed values

yes, no

Default value

no

    show_headers

Include request and response headers in the test report.

Allowed values

yes, no

Default value

no

    show_html

Include content of HTTP response in the test report.

Allowed values

yes, no

Default value

no

    status_code

Given numeric HTTP Status Code, tests response returned that value.

Default value

200 (OK).

    terse

Option to display shorter test report.
o summary

Only a one-line summary for each URL

o failed_only

Only tests that failed and the summary

o no

Show all tests and the summary

Default value

no

    test_name

Name associated with this URL in the test report and error messages.

    text_forbid

List of text strings that are forbidden to exist in the returned page.

See also the regex_forbid and ignore_case parameters.

    text_require

List of text strings that are required to exist in the returned page.

See also the regex_require and ignore_case parameters.

    timeout

Set the timeout value in seconds.

Default value

180

    url

URL to test.

If test parameter relative_urls is set to yes than URL for each test is treated as relative to the URL in the previous test. URL in the first test is treated as relative to http://localhost.

If test parameter relative_urls is set to no than each URL is treated as absolute. In this case if schema part of URL is omitted (i.e. URL doesn’t start with http://, ftp://, etc) then http:// is implied.

    user_agent

Set the product token that is used to identify the user agent on the network.

Default value

HTTP-WebTest/NN

where NN is version number of HTTP-WebTest.

RESTRICTIONS / BUGS

This module have been tested only on Unix (e.g., Solaris, Linux, AIX, etc.) but it should work on Win32 systems.

If you want to test https:// web sites you may have to install additional modules to enable SSL support in LWP. In short you may have to install Crypt::SSLeay module. For details see README.SSL file in LWP distro.
