All the (relevant) methods of ExperimentFakes and ExperimentTestUtils
are now defined on a new object called NimbusTestUtils. For convenience,
the old aliases still work, but they will be removed in a future bug.
There are also some new goodies, like
`NimbusTestUtils.assert.storeIsEmpty`, which is a port of a method from
our head.js files, and `NimbusTestUtils.removeStore`. This does require
you to give NimbusTestUtils access to the test scope (via
`NimbusTestUtils.init(this)`), but it lets us do actual assertions
instead of just throwing errors.
Nimbus' browser and xpcshell tests have been updated to use these new
helpers by replacing the internals of `assertEmptyStore` in each head.js
file with calls to them. They will be cleaned up to remove the wrapper
in a follow-up.
Additionally, `NimbusTestUtils.factories.recipe` will now return a
recipe that will *always* enroll. `ExperimentFakes.recipe` returns a
recipe that would only enroll 10% of the time and most tests that were
using `ExperimentFakes.recipe` were replacing that `bucketConfig` with
one that guaranteed enrollment. Existing callers do not have to change
until we migrate everything to `NimbusTestUtils`.
