NAME

Test::TraceCalls - which subs were called by which test scripts?

SYNOPSIS

In every module of your project:

        use Test::TraceCalls;

When you run your test suite:

        PERL_TRACE_CALLS=1 prove -lr t

For every file "t/foo.t" in your test suite, Test::TraceCalls will generate "t/foo.t.map" containing a JSON summary of which subs got called by that test file.

DESCRIPTION

Test::TraceCalls will trace calls to:

  • Subs defined the normal way sub name { ... }

  • Subs which have been imported, unless you unimport them later with namespace::autoclean or similar.

  • Subs generated by Moose/Moo/Mouse has.

Test::TraceCalls will NOT trace calls to:

  • Inherited subs, unless the package you inherit from also uses Test::TraceCalls.

  • Subs defined too late. (Including new generated by Moo sometimes.)

  • Subs with names starting with an underscore, but see below.

  • Subs with names not including a lower-case letter, because it's assumed these are just constants, but see below.

The sub name filtering can be controlled by passing a match coderef at import time. The default match coderef is just:

        use Test::TraceCalls match => sub {
                local $_ = shift;
                !/^_/ and /\p{Ll}/;
        };
