Cleanup translib and cvl go test cases (sonic-net#13)
Browse files Browse the repository at this point in the history
- Why I did it

There are few issues in cvl and translib go test code.

- How I did it

1) Fixed compilation is translib test code. Temporarily disabled ACL test codes from translib test since there are too many errors in it. Moved all common utility code in ACL test file into a new common file (app_utils_test.go).
2) Fixed the failures in cvl test code.
3) Added a new app module api_tests_app.go which provides dummy implementations of all app interface APIs for paths starting with /api-tests:. Errors can be simulated by including token /error/ in the path. This can be used by translib test code as well as translib client test code (REST or telemetry) to verify end-to-end of all cases without depending on actual app modules or database state.

- How to verify it

Run translib and cvl go test cases

- Description for the changelog
