.SH NAME
Perl::Critic::Policy::TestingAndDebugging::RequireTestLabels \- Tests should all have labels.
.SH AFFILIATION
.IX Header "AFFILIATION"
This Policy is part of the core Perl::Critic
distribution.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
Most Perl modules with regression tests use Test::More
as infrastructure for writing and running those tests.  It has an
easy, procedural syntax for writing comparisons of results to
expectations.
.PP
Most of the Test::More functions allow the programmer to add an
optional label that describes what each test is trying to judge.  When
a test goes wrong, these labels are very useful for quickly
determining where the problem originated.
.PP
This policy enforces that all Test::More functions have labels where
applicable.  This only applies to code that has a \f(CW\*(C`use Test::More\*(C'\fR or
\&\f(CW\*(C`require Test::More\*(C'\fR declaration (see below to add more test modules
to the list).
.SH CONFIGURATION
.IX Header "CONFIGURATION"
A list of additional modules to require label parameters be passed to
their methods can be specified with the \f(CW\*(C`modules\*(C'\fR option.  The list
must consist of whitespace-delimited, fully-qualified module names.
For example:
.PP
.Vb 2
\&    [TestingAndDebugging::RequireTestLabels]
\&    modules = My::Test::SubClass  Some::Other::Module
.Ve
.PP
The module list always implicitly includes Test::More.
