Sample Project to play with generation of code coverage info from Bazel.

The docker folder contains a Dockerfile that prepares the build environment (ubuntu 18.04 + Bazel 2.0.0). To start the container call"

 docker/run.sh 

It will build and start the container. The code is mounted in the folder /code.

To build:

cd /code bazel build //... 

To run the unit test:

bazel test //... 

To create the coverage report:

bazel coverage --instrument_test_targets --experimental_cc_coverage --combined_report=lcov --coverage_report_generator=@bazel_tools//tools/test/CoverageOutputGenerator/java/com/google/devtools/coverageoutputgenerator:Main //... genhtml bazel-out/_coverage/_coverage_report.dat -o report 

the report will be generated in the report folder
