/** |
|
13
|
|
|
* InitDbFixture represents the initial state needed for DB-related tests. |
|
14
|
|
|
* |
|
15
|
|
|
* Its main task is to toggle integrity check of the database during data loading. |
|
16
|
|
|
* This is needed by other DB-related fixtures (e.g. [[ActiveFixture]]) so that they can populate |
|
17
|
|
|
* data into the database without triggering integrity check errors. |
|
18
|
|
|
* |
|
19
|
|
|
* Besides, DbFixture also attempts to load an [[initScript|initialization script]] if it exists. |
|
20
|
|
|
* |
|
21
|
|
|
* You should normally use InitDbFixture to prepare a skeleton test database. |
|
22
|
|
|
* Other DB fixtures will then add specific tables and data to this database. |
|
23
|
|
|
* |
|
24
|
|
|
* For more details and usage information on InitDbFixture, see the [guide article on fixtures](guide:test-fixtures). |
