There are a number of possibilities to analyse test coverage and produce various reports. There are guides available from many sources, a good overview and link collection to more info can be found on Wikipedia:

|
A simple report for a single test can for example be made using this command:
|
||
|
|
|
||
|
|
```
|
||
|
|
gcov -s src/main/sensors -o obj/test/ battery_unittest.cc
|
||
|
|
```
|
||
|
|
|
||
|
|
To produce a coverage report in XML format usable by the Cobertura plugin in Jenkins requires installation of a Python script called "gcovr" from github:

|
||
|
|
|
||
|
|
Example usage in Jenkins:
|
||
|
|
|
||
|
|
```
|
||
|
|
/gcovr-install-path/gcovr/scripts/gcovr obj/test --root=src/main -x > coverage.xml
|
||
|
|
```
|
||
|
|
|
||
|
|
There are many other ways to produce test coverage reports in other formats, like html etc.
