Methods and systems for testing source code are disclosed. The method includes mounting a shared memory and launching a controller container. The controller container is configured to retrieve a repository identifier of a repository on which the source code is stored, and a build descriptor including build steps and an indicator of a build VM image for generating the build. The method further includes storing the build steps in the shared memory, retrieving the source code from the repository based on the repository identifier, and storing the retrieved source code in the shared memory. The method also includes launching a build container based on the indicator of the build VM image, the build container configured to retrieve the build steps and the source code from the shared memory and perform the build on the source code based on the steps defined in the build steps.
