I configured TeamCity to run python unittest with coverage. I have set the process to report coverage data using TeamCity service messages.
I am using default CodeCoverageL key to report the total line coverage rate.
I can see "Percentage Of Line Coverage" reported on the "Reported Statistics Values" tab, but when I click on the "View Trend" icon for the value it says that "No chart generated".
How can I make the chart to be generated?
