code coverage shows zero percentage - SonarQube

Question

We are using SonarQube 6.4

Code coverage for both front end code(JavaScript) & back end code(java) shows 0%

Developers claim they have unit test cases for every function or class they write

This application has database layer

What does code coverage 0% mean?

Answer 1

As stated in the docs sonarqube does not run tests, it simply imports report generated by other tools to display them along the other analysis.

So my guess is that you have not configured your CI chain to generate test reports to be shown in sonarqube.
