Reset the state of the database before the test?

Question

Yii

Hello! Faced such a problem.
Tests change values ​​in the database, and fixtures are rolled only once. Because of this, in some tests, I get the wrong values ​​that I expect - due to the fact that some other test changed the value in the table.
How to roll fixtures before each test?

Answer 1

Use phpunit database extension (PHPUnit_Extensions_Database_TestCase).
The DB will be set (data) from the fixtures for each test.

Answer 2

Don't test the base .

Answer 3

Look for a description of Continuous Integration for Yii.
Here is an example: Continuous Integration Part I

Answer 4

Use a separate database for tests if the tests are not integration ones. For each case, generate its own set of test data.
