531 | =head1 DESCSIPTION |
532 | |
e2a489c2 |
533 | Provides a set of Test::More tests for Schema objects. Testing a parsed |
9bbbf403 |
534 | schema is then as easy as writing a perl data structure describing how you |
e2a489c2 |
535 | expect the schema to look. Also provides maybe_plan for conditionally running |
536 | tests based on their dependencies. |
9bbbf403 |
537 | |
e2a489c2 |
538 | The data structures given to the test subs don't have to include all the |
9bbbf403 |
539 | possible values, only the ones you expect to have changed. Any left out will be |
540 | tested to make sure they are still at their default value. This is a usefull |
541 | check that you your parser hasn't accidentally set schema values you didn't |
e2a489c2 |
542 | expect it to. |
9bbbf403 |
543 | |
544 | For an example of the output run the t/16xml-parser.t test. |
545 | |
546 | =head1 Tests |
547 | |
e2a489c2 |
548 | All the tests take a first arg of the schema object to test, followed by a |
9bbbf403 |
549 | hash ref describing how you expect that object to look (you only need give the |
550 | attributes you expect to have changed from the default). |
e2a489c2 |
551 | The 3rd arg is an optional test name to pre-pend to all the generated test |
9bbbf403 |
552 | names. |

568 | =head1 CONDITIONAL TESTS |
569 | |
570 | The C<maybe_plan> function handles conditionally running an individual |
571 | test. It is here to enable running the test suite even when dependencies |
572 | are missing; not having (for example) GraphViz installed should not keep |
573 | the test suite from passing. |
574 | |
575 | C<maybe_plan> takes the number of tests to (maybe) run, and a list of |
576 | modules on which test execution depends: |
577 | |
578 | maybe_plan(180, 'SQL::Translator::Parser::MySQL'); |
579 | |
580 | If one of C<SQL::Translator::Parser::MySQL>'s dependencies does not exist, |
581 | then the test will be skipped. |

593 | |

594 | =item Test Count Constants |
595 | |
e2a489c2 |
596 | Constants to give the number of tests each *_ok sub uses. e.g. How many tests |
19458c2f |
597 | does field_ok run? Can then use these to set up the test plan easily. |
598 | |
9bbbf403 |
599 | =item Test skipping |
600 | |
601 | As the test subs wrap up lots of tests in one call you can't skip idividual |
602 | tests only whole sets e.g. a whole table or field. |
603 | We could add skip_* items to the test hashes to allow per test skips. e.g. |
604 | |
605 | skip_is_primary_key => "Need to fix primary key parsing.", |
606 | |
607 | =item yaml test specs |
608 | |
609 | Maybe have the test subs also accept yaml for the test hash ref as its a much |
610 | nicer for writing big data structures. We can then define tests as in input |
611 | schema file and test yaml file to compare it against. |
