Writing resource classes is similar to writing test classes.
The requirements are the same except that, instead of a
Run
function, you must provide two functions
named SetUp
and
CleanUp
. The SetUp
function must have the same signature as a test classs
Run
. The CleanUp
function is similar, but does not take a
context
parameter.
The setup function may add additional properties to the context. These properties will be visible only to tests that require this resource. To add a context property, use Python's dictionary assignment syntax.
Below is an example of setup and cleanup functions for a
resource which calls create_my_resource
and
destroy_my_resource
to do the work of creating
and destroying the resource. The resource is identified by a
string handle, which is inserted into the context under the name
Resource.handle, where it may be accessed by
tests. Context property names should always have the form
Class.name so that there is no risk of collision
between properties created by different resource classes.
