Continuous testing

Having already established a simple CI pipeline, it is very easy to extend it with testing. Since we are already using CMake and CTest for the building and testing process, all we need to do is add another step to our pipeline that will execute the tests. This step may look like this:

# Run the unit tests with ctest
test:
  stage: test
  script:
    - cd build
    - ctest .

An entire pipeline will therefore appear as follows:

cache:
  key: all
  paths:
    - .conan
    - build

default:
  image: conanio/gcc9

stages:
  - prerequisites
  - build
  - test # We add another stage that tuns the tests

before_script:
  - export CONAN_USER_HOME="$CI_PROJECT_DIR"

prerequisites:
  stage: prerequisites
  script:
    - pip install conan==1.34.1
    - conan profile new default || true
    - conan profile update settings.compiler=gcc default
    - conan profile update settings.compiler.libcxx=libstdc++11 default
    - conan profile update settings.compiler.version=10 default
    - conan profile update...
