|
|
* InitDbFixture represents the initial state needed for DB-related tests.
|
|
*
|
|
* Its main task is to toggle integrity check of the database during data loading.
|
|
* This is needed by other DB-related fixtures (e.g. [[ActiveFixture]]) so that they can populate
|
|
* data into the database without triggering integrity check errors.
|
|
*
|
|
* Besides, DbFixture also attempts to load an [[initScript|initialization script]] if it exists.
|
|
*
|
|
* You should normally use InitDbFixture to prepare a skeleton test database.
|
|
* Other DB fixtures will then add specific tables and data to this database.
|
|
*
|
|
* For more details and usage information on InitDbFixture, see the [guide article on fixtures](guide:test-fixtures).
