module to make sure you didn't emit any warnings while testing

In general, your tests shouldn't produce warnings. This module causes any warnings to be captured and stored. It automatically adds an extra test that will run when your script ends to check that there were no warnings. If there were any warnings, the test will give a "not ok" and diagnostics of where, when and what the warning was, including a stack trace of what was going on when it occurred.

If some of your tests are supposed to produce warnings then you should be capturing and checking them with Test::Warn, that way Test::NoWarnings will not see them and so not complain.

The test is run by an END block in Test::NoWarnings. It will not be run when any forked children exit.
