 #### Code Coverage
 Please make sure your code is fully tested. The Cloud Build integration tests are run with the `pytest-cov` code coverage plugin. They fail for PRs with a code coverage less than the threshold specified in `.coveragerc`. If your file is inside the main module and should be ignored by code coverage check, add it to the `omit` section of `.coveragerc`.
 
-Check for code coverage report in any Cloud Build integration test log. 
+Check for code coverage report in any Cloud Build integration test log.
 Here is a breakdown of the report:
 - `Stmts`: lines of executable code (statements).
 - `Miss`: number of lines not covered by tests.
