535 | =head1 DESCRIPTION |
9bbbf403 |
536 | |
e2a489c2 |
537 | Provides a set of Test::More tests for Schema objects. Testing a parsed |
9bbbf403 |
538 | schema is then as easy as writing a perl data structure describing how you |
9aabed4a |
539 | expect the schema to look. Also provides C<maybe_plan> for conditionally running |
e2a489c2 |
540 | tests based on their dependencies. |
9bbbf403 |
541 | |
e2a489c2 |
542 | The data structures given to the test subs don't have to include all the |
9bbbf403 |
543 | possible values, only the ones you expect to have changed. Any left out will be |
10f70490 |
544 | tested to make sure they are still at their default value. This is a useful |
9bbbf403 |
545 | check that you your parser hasn't accidentally set schema values you didn't |
e2a489c2 |
546 | expect it to. |
9bbbf403 |
547 | |
13eb146e |
548 | For an example of the output run the F<t/16xml-parser.t> test. |
9bbbf403 |
549 | |
550 | =head1 Tests |
551 | |
e2a489c2 |
552 | All the tests take a first arg of the schema object to test, followed by a |
9bbbf403 |
553 | hash ref describing how you expect that object to look (you only need give the |
554 | attributes you expect to have changed from the default). |
13eb146e |
555 | The 3rd arg is an optional test name to prepend to all the generated test |
9bbbf403 |
556 | names. |

572 | =head1 CONDITIONAL TESTS |
573 | |
574 | The C<maybe_plan> function handles conditionally running an individual |
575 | test. It is here to enable running the test suite even when dependencies |
576 | are missing; not having (for example) GraphViz installed should not keep |
577 | the test suite from passing. |
578 | |
579 | C<maybe_plan> takes the number of tests to (maybe) run, and a list of |
580 | modules on which test execution depends: |
581 | |
582 | maybe_plan(180, 'SQL::Translator::Parser::MySQL'); |
583 | |
584 | If one of C<SQL::Translator::Parser::MySQL>'s dependencies does not exist, |
585 | then the test will be skipped. |
586 | |
0142de97 |
587 | Instead of a number of tests, you can pass C<undef> if you're using |
588 | C<done_testing()>, or C<'no_plan'> if you don't want a plan at all. |

600 | |

601 | =item Test Count Constants |
602 | |
9aabed4a |
603 | Constants to give the number of tests each C<*_ok> sub uses. e.g. How many tests |
604 | does C<field_ok> run? Can then use these to set up the test plan easily. |
19458c2f |

9bbbf403 |
606 | =item Test skipping |
607 | |
4b2d9113 |
608 | As the test subs wrap up lots of tests in one call you can't skip individual |
9bbbf403 |
609 | tests only whole sets e.g. a whole table or field. |
9aabed4a |
610 | We could add C<skip_*> items to the test hashes to allow per test skips. e.g. |
9bbbf403 |
611 | |
612 | skip_is_primary_key => "Need to fix primary key parsing.", |
613 | |
614 | =item yaml test specs |
615 | |
13eb146e |
616 | Maybe have the test subs also accept yaml for the test hash ref as it is much |
9bbbf403 |
617 | nicer for writing big data structures. We can then define tests as in input |
618 | schema file and test yaml file to compare it against. |
