Fixture.before Method
Defines the before fixture hook. The before fixture hook runs before the beginning of the first test in the fixture.
fixture.before( fn(ctx) ) → this
| Parameter | Type | Description | 
|---|---|---|
| fn | Function | An asynchronous hook function that contains hook code. | 
| ctx | Object | A fixture context object that stores user-defined data. | 
Fixture hooks run between tests and, as such, cannot access the browser. Use them to perform server-side operations. To perform browser operations before and after tests, use test hooks.
Use the fixture.after hook to execute code after the final fixture test.
