546 | =head1 DESCSIPTION |
547 | |
e2a489c2 |
548 | Provides a set of Test::More tests for Schema objects. Testing a parsed |
9bbbf403 |
549 | schema is then as easy as writing a perl data structure describing how you |
e2a489c2 |
550 | expect the schema to look. Also provides maybe_plan for conditionally running |
551 | tests based on their dependencies. |
9bbbf403 |
552 | |
e2a489c2 |
553 | The data structures given to the test subs don't have to include all the |
9bbbf403 |
554 | possible values, only the ones you expect to have changed. Any left out will be |
555 | tested to make sure they are still at their default value. This is a usefull |
556 | check that you your parser hasn't accidentally set schema values you didn't |
e2a489c2 |
557 | expect it to. |
9bbbf403 |
558 | |
559 | For an example of the output run the t/16xml-parser.t test. |
560 | |
561 | =head1 Tests |
562 | |
e2a489c2 |
563 | All the tests take a first arg of the schema object to test, followed by a |
9bbbf403 |
564 | hash ref describing how you expect that object to look (you only need give the |
565 | attributes you expect to have changed from the default). |
e2a489c2 |
566 | The 3rd arg is an optional test name to pre-pend to all the generated test |
9bbbf403 |
567 | names. |

583 | =head1 CONDITIONAL TESTS |
584 | |
585 | The C<maybe_plan> function handles conditionally running an individual |
586 | test. It is here to enable running the test suite even when dependencies |
587 | are missing; not having (for example) GraphViz installed should not keep |
588 | the test suite from passing. |
589 | |
590 | C<maybe_plan> takes the number of tests to (maybe) run, and a list of |
591 | modules on which test execution depends: |
592 | |
593 | maybe_plan(180, 'SQL::Translator::Parser::MySQL'); |
594 | |
595 | If one of C<SQL::Translator::Parser::MySQL>'s dependencies does not exist, |
596 | then the test will be skipped. |

608 | |

609 | =item Test Count Constants |
610 | |
e2a489c2 |
611 | Constants to give the number of tests each *_ok sub uses. e.g. How many tests |
19458c2f |
612 | does field_ok run? Can then use these to set up the test plan easily. |
613 | |
9bbbf403 |
614 | =item Test skipping |
615 | |
616 | As the test subs wrap up lots of tests in one call you can't skip idividual |
617 | tests only whole sets e.g. a whole table or field. |
618 | We could add skip_* items to the test hashes to allow per test skips. e.g. |
619 | |
620 | skip_is_primary_key => "Need to fix primary key parsing.", |
621 | |
622 | =item yaml test specs |
623 | |
624 | Maybe have the test subs also accept yaml for the test hash ref as its a much |
625 | nicer for writing big data structures. We can then define tests as in input |
626 | schema file and test yaml file to compare it against. |
