pub fn setup()Expand description
Set up the fail point system.
Configures all fail points specified in the FAILPOINTS environment variable.
It does not otherwise change any existing fail point configuration
The format of FAILPOINTS is failpoint=actions;..., where
failpoint is the name of the fail point. For more information
about fail point actions see the cfg function and
the fail_point macro.
FAILPOINTS may configure fail points that are not actually defined. In
this case the configuration has no effect.
This function should generally be called prior to running a test with fail
points, and afterward paired with teardown.
Panics
Panics if an action is not formatted correctly.
