service hook in Azure DevOps project
How can you check Code Coverage
For .Net based applications, you can use the .Net Core CLI task to generate code coverage reports.
For Java based applications, you can use the Cobertura tool
Static Code Analysis
For Java you have PMD - https://pmd.github.io/
For .Net you can use Visual Studio itself -

flaky test - rule of thumb
As a rule of thumb, if you face a flaky test, do not assume that this is a test problem. You should suspect production code first and then the test.
What is a flaky test
It’s a test that sometimes fails, but if you retry it enough times, it passes, eventually
