Code coverage numbers are lower after upgrading from 6.0 -> 6.7.6->7.5

Must-share information (formatted with Markdown):

• which versions are you using (SonarQube, Scanner, Plugin, and any relevant extension)
  Sonarqube 7.5
• what are you trying to achieve
  Comparing coverage numbers between version 6.0 and 7.5
  Would like to understand why the coverage numbers are lower after upgrade.

Checkout this excellent blog post on the SonarSource blog that might be related your situation, specifically because this describes a change that occurred between v6.0 and v7.5 (I think… v6.2, but that’s not too important): Why did my coverage just drop?!

This is also a good guide regarding SonarQube and Code Coverage:

SonarQube and code coverage

Coverage, the why and the how Code coverage is an important quality metric that can be imported into SonarQube. The coverage report has to be computed by an external tool first and then SonarQube will be provided with information coming from this report during the analysis. To get coverage information in SonarQube, we provide the generic test data format for the coverage and the test execution reports. This is a simple format to gather tests and coverage information to inject into SonarQube…
