Execute the C++ example in Jenkins

Step 1: Create a new freestyle Jenkins project

Step 2: Go to project configuration and set the project location:

https://github.com/abanfi/cpp-coverage-test.git

This example can be use as remote repository in jenkins:

Step 3: Add a codeBeamer coverage importer post build step and set the properties.

Step 4: Execute a build: No more configuration is required, the project have already been built and the coverage report have been executed. The build should be executed without warning in a few sec.

Results

The test case tracker should contain the following test cases:

There should be a new test run in the test run tracker with the same elements:

The main test run details page should be look like:

Build and execute the examle project

This section contains basic steps and configuration which should be done before run our C coverage example project with googletest integration in Linux (the example command can be executed in Ubuntu/Linux Mint)

Requirements:

• Python v2.3 or newer (installed by default on modern Ubuntu)
• CMake v2.6.4 or newer (sudo apt-get install cmake)
• Gcovr (sudo apt install gcovr)
• Compiled and linked google test project (Here is a good example: http://stackoverflow.com/a/13513907)

Step by step install of google test:

• get the framework
• unpack and build
• install headers
• update linker cache

Commands:

$ wget https://github.com/google/googletest/archive/release-1.7.0.tar.gz
$ tar xf release-1.7.0.tar.gz
$ cd googletest-release-1.7.0
$ cmake -DBUILD_SHARED_LIBS=ON .
$ make
$ sudo cp -a include/gtest /usr/include
$ sudo cp -a libgtest_main.so libgtest.so /usr/lib/
$ sudo ldconfig -v | grep gtes

Makefiles should be updated before execution:

/Debug/makefile - the gtest path should be replaced at this line:

g++ -L/home/abanfi/googletest-release-1.7.0 -o"coverage" $(OBJS) $(USER_OBJS) $(LIBS)

/Debug/subdir.mk and /Debug/samples/subdir.mk - the gtest include path should be replaced at this line:

g++ -I/home/abanfi/googletest-release-1.7.0/include -O0 -g3 -Wall -c -fmessage-length=0 -fprofile-arcs -ftest-coverage -MMD -MP -MF"$(@:%.o=%.d)"

Go to the Debug Directory and execute the following commands:

$ make clean \\
$ make all \\
$ ./coverage --gtest_output=xml:coverage.junit.xml \\
$ gcovr -x -r .. -e ".+\.test\.cpp" > coverage.xml

The coverage.xml in Debug directory contains the cobertura report.
