Test all major features

[cereallarceny]

Description

We want to test all major features of the federated learning process in this repo. This includes:

• Mocking PyGrid in order to run the test suite without the use of another server running (these endpoints will likely be what you want to mock)
• Testing a flow with no authentication
• Testing a flow with basic JWT authentication (failing)
• Testing a flow with basic JWT authentication (passing)
• Testing the acceptance of a worker in an FL cycle request
• Testing the timeout for the re-application of an FL cycle request
• Testing the graceful handling of an error whereby a plan or model does not exist in PyGrid from what is being requested
• Testing the creation of one job
• Testing the creation of multiple jobs
• Testing that a job can be completed successfully
• Testing that multiple jobs can be completed successfully
• Testing that errors in a job can be caught by the onError handler and handled appropriately
• Testing that we can successfully report a model diff to PyGrid
• Any other related tests, or permutations of the above tests, that are required to pass for a developer to successfully use this library... in other words, be thorough and test everything you can think of that a developer might do.

Type of Test

• Unit test (e.g. checking a loop, method, or function is working as intended)
• Integration test (e.g. checking if a certain group or set of functionality is working as intended)
• Regression test (e.g. checking if by adding or removing a module of code allows other systems to continue to function as intended)
• Stress test (e.g. checking to see how well a system performs under various situations, including heavy usage)
• Performance test (e.g. checking to see how efficient a system is as performing the intended task)
• Other...

Expected Behavior

We expect all the above tests to pass.
