People, cultural aspects of DevOps

Wikipedia references:

The 'Three Amigos' is perhaps more technique then technology and thus it's easy to miss. The gist of it is that three people representing Business, Development and Testing sit down together to discuss a feature. Together they outline a list of acceptance criteria that should all be proven true by automated tests before the feature can be considered implemented.

My personal experience with coaching newly graduated developers it that they grasp new software at blazing speeds. This is as true for testing as it is for every other tool. If they didn't know JUnit/Hamcrest/Mockito (or the equivalent) before showing up, then they'll have picked it up within a month or so.

The problem of applying TDD has little to do with tooling. What all junior developers, and arguably also a lot of otherwise senior developers, all struggle with is what to test and why; how to test and what tools to use is less of a problem. Role-playing with the 'Three Amigos' and listing requirements should help them think critically about software using perspectives that they will otherwise lack.

Hi Jakob,

Thanks a lot for your suggestion for making this course great.

What all junior developers, and arguably also a lot of otherwise senior developers, all struggle with is what to test and why That's a good point. I wonder whether this is something for a previous course, such as software engineering fundamentals or introduction to testing.

The sooner you can get them stared thinking this way the better. Perhaps even introducing TDD as a concept without JUnit, using only System.out.println() and Object.equals() as a "testing framework" in the beginning.

The sooner you can get them stared thinking this way the better. 100% agree.

Devops-team habits:

Each organisation has a culture. A team has its own way of working within a larger organisation. Even if there are formal process descriptions, written rules and guidelines, I believe the team's own habits affects the result much more than anything else. It is, in a sense, a shared memory of how things are done. Especially if the team members are co-located and a bit isolated/protected from the rest of the organisation. The question is: how to identify and develop the right habits in a devops team?
