June 2022 Update

Published on 4 July 2022.

This is what I’ve been up to in June 2022:

• I started over with RLCI and tried to build it using an agile approach. The README has a bunch of more information about it. In this process, the following resources helped me:

  • Testing Without Mocks: A Pattern Language Again from James Shore. Gave me insight into how to design and test.

  • You Don’t Hate Mocks; You Hate Side-Effects The following quote explained it well to me the design relationship between pure functions and functions with side effects:

    We always have the option of replacing a side-effect with returning a value that represents the effect, as long as we can instruct the clients to interpret that value as a command to execute.

  • Favor real dependencies for unit testing This helped me solve a testing problem I had. More on that in an upcoming video.

• I discovered that one of the authors of Continuous Delivery, Dave Farley, has a Youtube channel. I found some of his videos interesting.

• I published another four programming videos on my Youtube channel:

  • How James Shore ruined my RLCI project.
  • Rebooting RLCI with an agile approach using TDD and zero friction development.
  • Adding continuous integration functionality to RLCI.
  • Making RLCI pipelines run in isolation.
