CI Pipeline should just build and test in the same step, rather then splitting into two separate steps

Created by: lecegues

Currently, the CI Pipeline splits the build-step and the unit-test-step; this requires repeated work on both steps. To reduce the time, it would be better to just add the unit tests to the build step. Additionally, this will allow the introduction of more steps (like smoke & integration steps) without seeing too much of an increased time in the pipeline
