This introduces a new test helper function which allows for turning a single-level array containing text strings into a data provider with named data sets, where the value of the data set will also be used as the name of the data set.
The function contains safeguards to ensure that it is only used with data compatible with this principle and will throw generic PHP exceptions when the data is incompatible. These type of exceptions will be displayed before the tests even start running and will stop the test run when they occur.
While generally speaking, all test cases ''should'' extend the base `WP_UnitTestCase_Base` class, this is still made a `public static` method to allow for a test, which by exception directly extends the PHPUnit base `TestCase` or the `PHPUnit_Adapter_TestCase`, to also be able to use this method.
Typical usage of this method:
{{{
public function data_provider_for_test_name() {
$array = array(
'value1',
'value2',
);
return $this->text_array_to_dataprovider( $array );
}
}}}
The returned result will look like:
{{{
array(
'value1' => array( 'value1' ),
'value2' => array( 'value2' ),
)
}}}

The short version:
1. Create a clean MySQL database and user. DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.
2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.
3. $ svn up
4. Run the tests from the "trunk" directory:
To execute a particular test:
$ phpunit tests/phpunit/tests/test_case.php
To execute all tests:
$ phpunit
Notes:
Test cases live in the 'tests' subdirectory. All files in that directory will be included by default. Extend the WP_UnitTestCase class to ensure your test is run.
phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run. This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs. Pure unit tests may be used also, of course.
Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.
phpunit is intended to run at the command line, not via a web server.
