=head1 DESCRIPTION

=head1 FUNCTIONS

=head2 findRuns

Find runs based on the options HASHREF provided.
See the documentation for L<testrail-runs>, as the long argument names there correspond to hash keys.

The primary routine of testrail-runs.

=over 4

=item HASHREF C<OPTIONS> - flags acceptable by testrail-tests

=item TestRail::API C<HANDLE> - TestRail::API object

=back

Returns ARRAYREF of run definition HASHREFs.

Get the tests specified by the options passed.

=over 4

=item HASHREF C<OPTS> - Options for getting the tests

=over 4

=item STRING C<PROJECT> - name of Project to look for tests in

=item STRING C<RUN> - name of Run to get tests from

=item ARRAYREF[STRING] C<CONFIGS> (optional) - names of configs run must satisfy, if part of a plan

=item ARRAYREF[STRING] C<USERS> (optional) - names of users to filter cases by assignee

=item ARRAYREF[STRING] C<STATUSES> (optional) - names of statuses to filter cases by

=back

Returns ARRAYREF of tests, and the run in which they belong.

=head2 findTests(opts,case1,...,caseN)

Given an ARRAY of tests, find tests meeting your criteria (or not) in the specified directory.

=over 4

=item HASHREF C<OPTS> - Options for finding tests:

=over 4

=item STRING C<MATCH> - Only return tests which exist in the path provided.  Mutually exclusive with no-match.

=item STRING C<NO-MATCH> - Only return tests which aren't in the path provided (orphan tests).  Mutually exclusive with match.

=item BOOL C<NO-RECURSE> - Do not do a recursive scan for files.

=item BOOL C<NAMES-ONLY> - Only return the names of the tests rather than the entire test objects.

=item STRING C<EXTENSION> (optional) - Only return files ending with the provided text (e.g. .t, .test, .pl, .pm)

=back

=item ARRAY C<CASES> - Array of cases to translate to pathnames based on above options.

=back

Returns tests found that meet the criteria laid out in the options.
Provides absolute path to tests if match is passed; this is the 'full_title' key if names-only is false/undef.
Dies if mutually exclusive options are passed.
