hey team,
In pull request template(https://github.com/apache/incubator-dubbo/blob/master/PULL_REQUEST_TEMPLATE.md), this is one item to ask all pr to "Write necessary unit-test to verify your logic correction" Codecov has feature to fail PR if test coverage went down. Which means for any pull request, if it add some code without any unit test, the PR will fail This can help to increase test coverage. Any thoughts?
