SYNOPSIS

12        use FindBin '$Bin';
13        use Test::More;
14        use Test::SQL::Translator;

17        my $sqlt = SQL::Translator->new(
18            parser => "Magic",
19            filename => "$Bin/data/magic/test.magic",
20            ...
21        );
22        ...
23        my $schema = $sqlt->schema;
24
25        # Test the table it produced.
26        table_ok( $schema->get_table("Customer"), {
27            name => "Customer",

DESCSIPTION

59       Provides a set of Test::More tests for Schema objects. Testing a parsed
60       schema is then as easy as writing a perl data structure describing how
61       you expect the schema to look. Also provides maybe_plan for
62       conditionally running tests based on their dependencies.
63
64       The data structures given to the test subs don't have to include all
65       the possible values, only the ones you expect to have changed. Any left
66       out will be tested to make sure they are still at their default value.
67       This is a usefull check that you your parser hasn't accidentally set
68       schema values you didn't expect it to.
69
70       For an example of the output run the t/16xml-parser.t test.
71

Tests

73       All the tests take a first arg of the schema object to test, followed
74       by a hash ref describing how you expect that object to look (you only
75       need give the attributes you expect to have changed from the default).
76       The 3rd arg is an optional test name to pre-pend to all the generated
77       test names.
78
79   table_ok
80   field_ok
81   constraint_ok
82   index_ok
83   view_ok
84   trigger_ok
85   procedure_ok

CONDITIONAL TESTS

87       The "maybe_plan" function handles conditionally running an individual
88       test.  It is here to enable running the test suite even when
89       dependencies are missing; not having (for example) GraphViz installed
90       should not keep the test suite from passing.
91
92       "maybe_plan" takes the number of tests to (maybe) run, and a list of
93       modules on which test execution depends:
94
95           maybe_plan(180, 'SQL::Translator::Parser::MySQL');
96
97       If one of "SQL::Translator::Parser::MySQL"'s dependencies does not
98       exist, then the test will be skipped.

TODO

105       Test the tests!
106       Test Count Constants
107           Constants to give the number of tests each *_ok sub uses. e.g. How
108           many tests does field_ok run? Can then use these to set up the test
109           plan easily.
110
111       Test skipping
112           As the test subs wrap up lots of tests in one call you can't skip
113           idividual tests only whole sets e.g. a whole table or field.  We
114           could add skip_* items to the test hashes to allow per test skips.
115           e.g.
116
117            skip_is_primary_key => "Need to fix primary key parsing.",
118
119       yaml test specs
120           Maybe have the test subs also accept yaml for the test hash ref as
121           its a much nicer for writing big data structures. We can then
122           define tests as in input schema file and test yaml file to compare
123           it against.
