9 Test::Leaner - A slimmer Test::More for when you favor performance over completeness.
17 our $VERSION = '0.01';
21 use Test::Leaner tests => 10_000;
24 is $one, 1, "checking situation $_";
30 When profiling some L<Test::More>-based test script that contained about 10 000 unit tests, I realized that 60% of the time was spent in L<Test::Builder> itself, even though every single test actually involved a costly C<eval STRING>.
32 This module aims to be a partial replacement to L<Test::More> in those situations where you want to run a large number of simple tests.
33 Its functions behave the same as their L<Test::More> counterparts, except for the following differences :
39 Stringification isn't forced on the test operands.
40 However, L</ok> honors C<'bool'> overloading, L</is> honors C<'eq'> overloading and L</cmp_ok> honors whichever overloading category corresponds to the specified operator.
44 L</pass>, L</fail>, L</ok>, L</is>, L</isnt>, L</like>, L</unlike> and L</cmp_ok> are all guaranteed to return the truth value of the test.
48 C<use_ok>, C<require_ok>, C<can_ok>, C<isa_ok>, C<new_ok>, C<subtest>, C<explain>, C<TODO> blocks and C<todo_skip> are not implemented.

506 L<Test::Leaner> also provides some functions of its own, which are never exported.
508 =head2 C<tap_stream [ $fh ]>
510 Read/write accessor for the filehandle to which the tests are outputted.
511 On write, it also turns autoflush on onto C<$fh>.
513 Note that it can only be used as a write accessor before you start any thread, as L<threads::shared> cannot reliably share filehandles.
515 Defaults to C<STDOUT>.
519 sub tap_stream (;*) {
523 my $fh = select $TAP_STREAM;
533 =head2 C<diag_stream [ $fh ]>
535 Read/write accessor for the filehandle to which the diagnostics are printed.
536 On write, it also turns autoflush on onto C<$fh>.
538 Just like L</tap_stream>, it can only be used as a write accessor before you start any thread, as L<threads::shared> cannot reliably share filehandles.
540 Defaults to C<STDERR>.
544 sub diag_stream (;*) {
546 $DIAG_STREAM = $_[0];
548 my $fh = select $DIAG_STREAM;
