=head1 SYNOPSIS

    my $harness = TestHarness->new(
        this_file => $FindBin::Script
    );
    my %selenium_args = %{ $harness->base_caps };
    unless ($harness->mocks_exist_for_platform) {
        plan skip_all => "Mocking of tests is not been enabled for this platform";
    }

=attr this_file

Required. Pass in the short name of the test file in use so we can
figure out where the corresponding recording belongs. For a test file
named C<t/01-driver.t>, we'd expect this argument to be
C<01-driver.t>.
