Provide a FakeUnleash facade for automated testing

[julioz]

Describe the feature request

Similar to what exists in the Java SDK, we would like to allow feature flag value manipulation in the local development environment, to facilitate unit and integration testing.

Background

No response

Solution suggestions

Would it make sense to extract an interface into unleash.ts and then include a fake implementation that stubs every method call?

Hi @julioz this is a good suggestion, similar to Unleash/unleash-proxy-client-js#241

In this case you can use bootstrap and disabling polling to provide the initial values for testing, providing a different instance for each test depending on your needs.

Despite that, this would be nice to have, but unfortunately not in our priorities at this moment. We'd be happy to review and provide support in case you want to make a contribution.
