## Usage
* `dev/testsession/start`: A test database will be constructed, and your
browser session will be amended to use this database.
* `dev/testsession/start?fixture=<fixturefile>`: Same as above, but also loads a YAML fixture
in the format generally accepted by `SapphireTest` (see [fixture format docs](http://doc.silverstripe.org/framework/en/topics/testing/fixtures)). The path should be relative to the webroot.
* `dev/testsession/end`: Removes the test state, and resets to the original database
* `dev/testsession/setdb?database=<database-name>`: Set an alternative database name in the current
browser session as a cookie. Does not actually create the database,
that's usually handley by `SapphireTest::create_temp_db()`.
* `dev/testsession/emptydb`: Empties the test state.
You start a test session by manually requesting a certain URL,
and interact with it through other URL endpoints.
Commands:
* `dev/testsession/start`: Sets up test state, most commonly a test database will be constructed,
and your browser session will be amended to use this database. See "Parameters" documentation below.
* `dev/testsession/end`: Removes the test state, and resets to the original database.
* `dev/testsession/loadfixture?fixture=<path>`: Loads a fixture into an existing test state.
* `dev/testsession/clear`: Empties the test state.
Parameters for "dev/testsession/start":
* `fixture`: Loads a YAML fixture in the format generally accepted by `SapphireTest`
(see [fixture format docs](http://doc.silverstripe.org/framework/en/topics/testing/fixtures)).
The path should be relative to the webroot.
* `database`: Set an alternative database name in the current
browser session as a cookie. Does not actually create the database,
that's usually handled by `SapphireTest::create_temp_db()`.
Note: The database names are limited to a specific naming convention as a security measure:
The "ss_tmpdb" prefix and a random sequence of seven digits.
This avoids the user gaining access to other production databases available on the same connection.
Example usage with parameters:
dev/testsession/start?database=ss_tmpdb_1234567&fixture=cms/tests/controller/CMSMainTest.yml
Note: The database names are limited to a specific naming convention as a security measure:
The "ss_tmpdb" prefix and a random sequence of seven digits.
This avoids the user gaining access to other production databases available on the same connection.
