Lots of talk of testing and of organisation design at the moment in the devops community, at least based on posts I read this week. Also I’m seeing more people talk about how we change to adopt devops practices, rather than just what those practices are. Anyone with a good stories please write them up and send me the links.

One of the advantages of continuous integration is having one shared place to do things - for this next post that’s to collect useful metrics. Quite a lot of detail about the types quality metrics you can collect as part of a pipeline, including some examples of why it’s a useful idea.
Adding performance testing to continuous integration pipelines can be tricky - deciding when to run them, for how long and determining what to assert on isn’t as simple as lots of other types of testing. This presentation shows an example from one organisation doing this successfully.
