.SH DESCRIPTION
.IX Header "DESCRIPTION"
Loading this plugin causes your tests to fail if there any warnings while they
run. Each warning generates a new failing test and the warning content is
outputted via \f(CW\*(C`diag\*(C'\fR.
.PP
This module uses \f(CW$SIG{_\|_WARN_\|_}\fR, so if the code you\*(Aqre testing sets this,
then this module will stop working.
.SH "ECHOING WARNINGS"
.IX Header "ECHOING WARNINGS"
By default, this module suppresses the warning itself so it does not go to
\&\f(CW\*(C`STDERR\*(C'\fR. If you\*(Aqd like to also have the warning go to \f(CW\*(C`STDERR\*(C'\fR untouched,
you can ask for this with the \f(CW\*(C`echo\*(C'\fR import argument:
