The goal of this project is to build project with following tools:

• C++ version: C++11
• Build system: CMake
• C++ compiler: g++ or Visual Studio
• Libraries: STL only
• Code coverage report: lcov and OpenCppCoverage(note: it should show the code coverage is below 100%)
• CodeCov (code coverage is measured by CodeCov).
• Source: multiple files

Goes to Richel Bilderbeek for inspiration and all work on Travis CI tutorials. Here is a link to a project with the same structure (without lcov), and here is a list of all his Travis configuration examples.

To build the project you need to install CMake. (Install instructions) To display a code coverage report in the console, install lcov. (Download lcov, Instructions)

1. Compile with code coverage instrumentation enabled (GCC).
2. Execute the tests to generate the coverage data.
3. (Optionally) generate and customize reports with lcov.
4. Upload to CodeCov using the bash uploader.

Add to your .travis.yml file:

addons:
  apt:
    packages: lcov

after_success:
# Create lcov report
- lcov --capture --directory . --output-file coverage.info
- lcov --remove coverage.info '/usr/*' --output-file coverage.info # filter system-files
- lcov --list coverage.info # debug info
# Uploading report to CodeCov
- bash <(curl -s https://codecov.io/bash) -f coverage.info || echo "Codecov did not collect coverage reports"

By default the bash uploader processes the coverage data using gcov when no file is supplied.

after_success:
- bash <(curl -s https://codecov.io/bash) || echo "Codecov did not collect coverage reports"

Add to your .travis.yml file:

after_success:
  - bash <(curl -s https://codecov.io/bash) -t uuid-repo-token

This repo can serve as the starting point for a new project. The following is worth noticing:

1. Use of a build script instead of putting the commands into .travis.yml

• Allows local testing
• Allows usage of set -e to error out with meaningfull messages on any command failure

2. Separate testing source tree

• Allows to easily enable/disable testing
• Allows usage in parent projects (you don't want to build the tests if you are consumed)
• You may want to exclude coverage of test files which is easier when they are in a separate folder. Remember to use full paths for patterns (like '*/tests/*')

3. Use of travis cache to cache manually build 3rd-party dependencies (like boost)

• Speeds up build
• More can be added (e.g. ccache)
• Those need to be excluded from coverage info too
