Test::Builder provides the a building block upon which to write your own test libraries I. =head2 Construction =over 4 =item B my $Test = Test::Builder->new; Returns a Test::Builder object representing the current state of the test. Since you only run one test per program, there is B Test::Builder object. No matter how many times you call new(), you're getting the same object.

It's ok for your test to change where STDOUT and STDERR point to, Test::Builder's default output settings will not be affected. =over 4 =item B $Test->diag(@msgs); Prints out the given $message. Normally, it uses the failure_output() handle, but if this is for a TODO test, the todo_output() handle is used. Output will be indented and marked with a # so as not to interfere with test output. A newline will be put on the end if there isn't one already. We encourage using this rather than calling print directly. Returns false. Why?

my @tests = $Test->details; Like summary(), but with a lot more detail. $tests[$test_num - 1] = { 'ok' => is the test considered a pass? actual_ok => did it literally say 'ok'? name => name of the test (if any) type => type of test (if any, see below). reason => reason for the above (if any) }; 'ok' is true if Test::Harness will consider the test to be a pass. 'actual_ok' is a reflection of whether or not the test literally printed 'ok' or 'not ok'. This is for examining the result of 'todo' tests. 'name' is the name of the test. 'type' indicates if it was a special test. Normal tests have a type of ''. Type can be one of the following: skip see skip() todo see todo() todo_skip see todo_skip() unknown see below Sometimes the Test::Builder test counter is incremented without it printing any test output, for example, when current_test() is changed. In these cases, Test::Builder doesn't know the result of the test, so it's type is 'unkown'. These details for these tests are filled in. They are considered ok, but the name and actual_ok is left undef. For example "not ok 23 - hole count # TODO insufficient donuts" would result in this structure: $tests[22] = # 23 - 1, since arrays start from 0. { ok => 1, # logically, the test passed since it's todo actual_ok => 0, # in absolute terms, it failed name => 'hole count', type => 'todo', reason => 'insufficient donuts' }; =cut sub details { return @Test_Results; } =item B my $todo_reason = $Test->todo; my $todo_reason = $Test->todo($pack); todo() looks for a $TODO variable in your tests. If set, all tests will be considered 'todo' (see Test::More and Test::Harness for details). Returns the reason (ie. the value of $TODO) if running as todo tests, false otherwise. todo() is pretty part about finding the right package to look for $TODO in. It uses the exported_to() package to find it. If that's not set, it's pretty good at guessing the right package to look at. Sometimes there is some confusion about where todo() should be looking for the $TODO variable. If you want to be sure, tell it explicitly what $pack to use. =cut sub todo { my($self, $pack) = @_; $pack = $pack || $self->exported_to || $self->caller(1); no strict 'refs'; return defined ${$pack.'::TODO'} ? ${$pack.'::TODO'} : 0; } =item B my $package = $Test->caller; my($pack, $file, $line) = $Test->caller; my($pack, $file, $line) = $Test->caller($height); Like the normal caller(), except it reports according to your level(). =cut sub caller { my($self, $height) = @_; $height ||= 0; my @caller = CORE::caller($self->level + $height + 1); return wantarray ? @caller : $caller[0]; } =back =cut =begin _private =over 4 =item B<_sanity_check> _sanity_check(); Runs a bunch of end of test sanity checks to make sure reality came through ok.

The test number is shared amongst all threads. This means if one thread sets the test number using current_test() they will all be effected. =head1 EXAMPLES CPAN can provide the best examples.
