371 | =head1 NAME |
372 | |
373 | Test::Harness - run perl standard test scripts with statistics |
374 | |
375 | =head1 SYNOPSIS |
376 | |
377 | use Test::Harness; |
378 | |
379 | runtests(@tests); |
380 | |
381 | =head1 DESCRIPTION |
382 | |
7b13a3f5 |
383 | (By using the L<Test> module, you can write test scripts without |
384 | knowing the exact output this module expects. However, if you need to |
385 | know the specifics, read on!) |
386 | |
cb1a09d0 |
387 | Perl test scripts print to standard output C<"ok N"> for each single |
388 | test, where C<N> is an increasing sequence of integers. The first line |
c0ee6f5c |
389 | output by a standard test script is C<"1..M"> with C<M> being the |
cb1a09d0 |
390 | number of tests that should be run within the test |
c0ee6f5c |

392 | named as arguments and checks standard output for the expected |
393 | C<"ok N"> strings. |

395 | After all tests have been performed, runtests() prints some |

398 | =head2 The test script output |
399 | |
400 | Any output from the testscript to standard error is ignored and |
401 | bypassed, thus will be seen by the user. Lines written to standard |
c0ee6f5c |
402 | output containing C</^(not\s+)?ok\b/> are interpreted as feedback for |
403 | runtests(). All other lines are discarded. |
6c31b336 |
404 | |
405 | It is tolerated if the test numbers after C<ok> are omitted. In this |
406 | case Test::Harness maintains temporarily its own counter until the |
407 | script supplies test numbers again. So the following test script |
408 | |
409 | print <<END; |
410 | 1..6 |
411 | not ok |
412 | ok |
413 | not ok |
414 | ok |
415 | ok |
416 | END |
417 | |
418 | will generate |
419 | |
420 | FAILED tests 1, 3, 6 |
421 | Failed 3/6 tests, 50.00% okay |
422 | |
423 | The global variable $Test::Harness::verbose is exportable and can be |
c0ee6f5c |
424 | used to let runtests() display the standard output of the script |
6c31b336 |
425 | without altering the behavior otherwise. |
426 | |
fb73857a |
427 | The global variable $Test::Harness::switches is exportable and can be |
428 | used to set perl command line options used for running the test |
429 | script(s). The default value is C<-w>. |
430 | |

431 | If the standard output line contains substring C< # Skip> (with |
432 | variations in spacing and case) after C<ok> or C<ok NUMBER>, it is |
433 | counted as a skipped test. If the whole testscript succeeds, the |
434 | count of skipped tests is included in the generated output. |
435 | |
45c0de28 |
436 | C<Test::Harness> reports the text after C< # Skip(whatever)> as a |
437 | reason for skipping. Similarly, one can include a similar explanation |
438 | in a C<1..0> line emitted if the test is skipped completely: |
439 | |
440 | 1..0 # Skipped: no leverage found |

475 | |
17a79f5b |
476 | Setting C<HARNESS_IGNORE_EXITCODE> makes harness ignore the exit status |
9b0ceca9 |
477 | of child processes. |
478 | |
0d0c0d42 |
479 | Setting C<HARNESS_NOTTY> to a true value forces it to behave as though |
480 | STDOUT were not a console. You may need to set this if you don't want |
481 | harness to output more frequent progress messages using carriage returns. |
482 | Some consoles may not handle carriage returns properly (which results |
483 | in a somewhat messy output). |
484 | |
17a79f5b |
485 | If C<HARNESS_FILELEAK_IN_DIR> is set to the name of a directory, harness |
486 | will check after each test whether new files appeared in that directory, |
487 | and report them as |
488 | |
489 | LEAKED FILES: scr.tmp 0 my.db |
490 | |
491 | If relative, directory name is with respect to the current directory at |
492 | the moment runtests() was called. Putting absolute path into |
493 | C<HARNESS_FILELEAK_IN_DIR> may give more predicatable results. |
494 | |
f19ae7a7 |
495 | Harness sets C<HARNESS_ACTIVE> before executing the individual tests. |
496 | This allows the tests to determine if they are being executed through the |
497 | harness or by any other means. |

505 | |
506 | Either Tim Bunce or Andreas Koenig, we don't know. What we know for |
507 | sure is, that it was inspired by Larry Wall's TEST script that came |
b876d4a6 |
508 | with perl distributions for ages. Numerous anonymous contributors |
509 | exist. Current maintainer is Andreas Koenig. |

512 | |
513 | Test::Harness uses $^X to determine the perl binary to run the tests |
6c31b336 |
514 | with. Test scripts running via the shebang (C<#!>) line may not be |
515 | portable because $^X is not consistent for shebang scripts across |
cb1a09d0 |
516 | platforms. This is no problem when Test::Harness is run with an |
6c31b336 |
517 | absolute path to the perl binary or when $^X can be found in the path. |
