[rohitgr7]

@awaelchli do you know why some tests here are getting canceled here?? Something wrong with mock tests here?

[edenlightning]

@tchaton make sure tests here are good?

[rohitgr7]

@awaelchli can't get the tests working. Not familiar with the error it's raising. Can you check, please?? Thanks.

[awaelchli]

ok, I try to find what's wrong :)

[awaelchli]

@rohitgr7 see my modifications to test.

1. need to mock each 3rd party experiment object, because we don't install it in CI
2. each logger has slightly different interface
   with the mocks it allows us to catch the exact call to the experiment object.
