Warnings are an important part of any application. Your web application should
warn its operators when something is amiss.
Almost as importantly, your web application should gracefully cope with bad
input, the back button, and all other aspects of the user experience.
Unfortunately, tests seldom cover what happens when things go poorly. Are you
sure that your application correctly denies that action and logs the
failure? Are you sure it will tomorrow?
This module lets you retrieve the warnings that your forked server issues. That
way you can test that your application continues to issue warnings when it
makes sense. Catching the warnings also keeps your test output tidy. Finally,
youll be able to see (and be notified via failing tests) when your
application issues new, unexpected warnings so you can fix them immediately.
