Result:
Next try:
git clean -xdfThe same code for many environments.
One change can cause regression.
Oops! The load test is triggered after deploying the production!
We need something to test and track the impact of our changes!

Transforms and interprets Groovy code as in Jenkins
Intercepts method calls for stack tracing and mocking
Done:
