Code coverage is a number of metrics that measure how your code is covered by unit tests. TeamCity supports the following coverage engines out of the box:
Java, see Configuring Java Code Coverage
IntelliJ IDEA coverage (bundled)
EMMA open-source toolkit (bundled)
JaCoCo open-source (bundled)
.NET: see Configuring .NET Code Coverage
JetBrains dotCover (bundled)
For importing reports from other coverage tools, see the related notes.
For importing coverage results in TeamCity, see this section.
To get the code coverage information displayed in TeamCity for the supported tools, you need to configure it in the dedicated section of a Build Runner settings page. The following build runners include code coverage support:
Note that currently the Maven2 runner supports IntelliJ IDEA and JaCoCo coverage engines.
The code coverage results can be viewed on the Overview tab of the Working with Build Results; detailed report is displayed on the dedicated Working with Build Results tab.
The chart for code coverage is also available on the Statistic Charts tab of the build configuration.
