// Some tests will try to install a jasmine clock. In order to effectively install a clock,

// are testing. Since we just required() all modules, the modules have typically already started
// their setTimeouts or setIntervals making installing an effective clock from tests difficult. By
// clearing the cache here, it allows the tests to effectively install the clock before
// requiring the module anew.
