100 | =head1 DESCRIPTION
|
---|
101 |
|
---|
102 | Test::Simple and Test::More have proven to be popular testing modules,
|
---|
103 | but they're not always flexible enough. Test::Builder provides the a
|
---|
104 | building block upon which to write your own test libraries I<which can
|
---|
105 | work together>.

---|
112 |
|
---|
113 | my $Test = Test::Builder->new;
|
---|
114 |
|
---|
115 | Returns a Test::Builder object representing the current state of the
|
---|
116 | test.
|
---|
117 |
|
---|
118 | Since you only run one test per program C<new> always returns the same
|
---|
119 | Test::Builder object. No matter how many times you call new(), you're
|
---|
120 | getting the same object. This is called a singleton. This is done so that
|
---|
121 | multiple modules share such global information as the test counter and
|
---|
122 | where test output is going.
|
---|
123 |
|
---|
124 | If you want a completely new Test::Builder object different from the
|
---|
125 | singleton, use C<create>.

|
---|
140 |
|
---|
141 | Ok, so there can be more than one Test::Builder object and this is how
|
---|
142 | you get it. You might use this instead of C<new()> if you're testing
|
---|
143 | a Test::Builder based module, but otherwise you probably want C<new>.
|
---|
144 |
|
---|
145 | B<NOTE>: the implementation is not complete. C<level>, for example, is
|
---|
146 | still shared amongst B<all> Test::Builder objects, even ones created using
|
---|
147 | this method. Also, the method name may change in the future.

1415 | 'ok' is true if Test::Harness will consider the test to be a pass.

1416 |
|
---|
1417 | 'actual_ok' is a reflection of whether or not the test literally
|
---|
1418 | printed 'ok' or 'not ok'. This is for examining the result of 'todo'
|
---|
1419 | tests.
|

1420 |
|
---|
1421 | 'name' is the name of the test.

1422 |

1423 | 'type' indicates if it was a special test. Normal tests have a type

1424 | of ''. Type can be one of the following:
|

1425 |
|
---|
1426 | skip see skip()
|
---|
1427 | todo see todo()
|
---|
1428 | todo_skip see todo_skip()
|

1429 | unknown see below
|

1430 |
|

1431 | Sometimes the Test::Builder test counter is incremented without it
|
---|
1432 | printing any test output, for example, when current_test() is changed.
|
---|
1433 | In these cases, Test::Builder doesn't know the result of the test, so
|
---|
1434 | it's type is 'unkown'. These details for these tests are filled in.
|
---|
1435 | They are considered ok, but the name and actual_ok is left undef.
|
---|
1436 |
|
---|

|

|

1439 |
|
---|
1440 | $tests[22] = # 23 - 1, since arrays start from 0.
|
---|
1441 | { ok => 1, # logically, the test passed since it's todo
|

1442 | actual_ok => 0, # in absolute terms, it failed

1443 | name => 'hole count',

1460 | todo() looks for a $TODO variable in your tests. If set, all tests
|
---|
1461 | will be considered 'todo' (see Test::More and Test::Harness for
|
---|
1462 | details). Returns the reason (ie. the value of $TODO) if running as

---|
1463 | todo tests, false otherwise.
|
---|
1464 |
|
---|
1465 | todo() is about finding the right package to look for $TODO in. It
|
---|
1466 | uses the exported_to() package to find it. If that's not set, it's
|
---|
1467 | pretty good at guessing the right package to look at based on $Level.
|
---|
1468 |
|
---|
1469 | Sometimes there is some confusion about where todo() should be looking
|
---|
1470 | for the $TODO variable. If you want to be sure, tell it explicitly
|

1471 | what $pack to use.

1695 | =head1 EXIT CODES
|
---|
1696 |
|
---|
1697 | If all your tests passed, Test::Builder will exit with zero (which is
|
---|
1698 | normal). If anything failed it will exit with how many failed. If
|
---|
1699 | you run less (or more) tests than you planned, the missing (or extras)
|
---|
1700 | will be considered failures. If no tests were ever run Test::Builder
|
---|
1701 | will throw a warning and exit with 255. If the test died, even after
|
---|
1702 | having successfully completed all its tests, it will still be
|
---|
1703 | considered a failure and will exit with 255.
|
---|
1704 |
|
---|
1705 | So the exit codes are...
|
---|
1706 |
|
---|
1707 | 0 all tests successful
|
---|
1708 | 255 test died or all passed but wrong # of tests run
|
---|
1709 | any other number how many failed (including missing or extras)
|
---|
1710 |
|
---|
1711 | If you fail more than 254 tests, it will be reported as 254.
|
---|

1714 | =head1 THREADS
|
---|
1715 |
|
---|
1716 | In perl 5.8.0 and later, Test::Builder is thread-safe. The test
|
---|
1717 | number is shared amongst all threads. This means if one thread sets
|
---|
1718 | the test number using current_test() they will all be effected.
|
---|
1719 |
|
---|
1720 | Test::Builder is only thread-aware if threads.pm is loaded I<before>
|
---|
1721 | Test::Builder.

---|

---|
1723 | =head1 EXAMPLES
|
---|
1724 |
|
---|
1725 | CPAN can provide the best examples. Test::Simple, Test::More,
|
---|
1726 | Test::Exception and Test::Differences all use Test::Builder.
