Short description of the changes

Makefile Changes

• smoke-tests/collector/data.json makes sure there is always a data.json file in the collector folder so that tests can run reliably
• smoke-sdk-grpc runs bats tests for smoke tests over gRPC
• smoke-sdk-http runs bats tests for smoke tests over http/protobuf
• smoke-sdk runs bats tests for all sdk tests
• smoke runs all bats smoke tests
• unsmoke tears down setup for smoke tests
• resmoke tears down and then runs smoke tests

CI Changes

• added bats 1.0 orb and installed 1.0 bats during smoke-tests job
• stored test results so that CI test tab is populated correctly
• stored artifacts for test results and JSON files with traces

How to test

Local Makefile

1. Fetch and checkout this branch
2. Test the new commands by running make <command>
3. Locally, it is important to unsmoke after running a set of tests, you can get into a weird state if you run clean without unsmoke.

CI

• Test output shows up in the console
• Test tab is populated correctly
• Artifacts are uploaded
• Tests are passing
