I have spent some time trying to simplify the release process. For a variety of reasons, we can only release on Thursdays. The code is “frozen” on Tuesday before it can be released on Thursday. But we sometimes squeeze in a quick fix on Wednesday as well.
The question, is when should QA test the code?
Here is what I have seen happen:
- Dev writes code and sends it to QA.
- QA finds problems, sends it back to the Dev.
- Dev fixes and sends it back to QA.
I have seen a Dev fix their code on Tuesday, and then QA comes back on Wednesday with problems, when the code should have been frozen anyway.
I am looking, what should be the best solution here.
We have several problems going on at once:
- Developers test on the same server as QA tests. I am working to switch developers to a separate Dev server, but it is a long work in progress.
- We don’t have an easy way to revert code back from the QA server. It is easier to build revisions than revert changes. We can try to revert code more, but it will require a culture change.
- QA don’t really have a schedule when they are supposed to do functional testing vs regression testing.
I don’t know what is the best way to proceed forward. Thus far, I haven’t thought too much about the QA because I was focused more on getting releases out. Now that releasing is more simplified, that we can potentially do weekly releases, I am trying to see how we should proceed with the testing process.

Ephemeral test environments are a great tool for this kind of stuff. We do work on a feature branch and spin up a test environment for that feature. QA happens there, then it gets merged to master once they approve it.
In our workflow, it deploys immediately, but you could just as easily adapt that to cut a release every Thursday. Then each release can just contain whatever makes its way into master by Thursday. You might need to add more process if there’s release notes etc that need to be coordinated. My suggestion on that would be to cut the release on Tuesday or Wednesday, then whoever does that documentation can look at what made the cut and spend a day documenting it, then just press the deploy button on Thursday once they’re done.
Your QA team should be building automated regression tests and automating their tests so that they can be run locally as part of the development cycle or as a job in your CI system.
That would decouple this incredibly tight release cycle that you currently have
Your company seem to have a significant technical debt in environments, tooling, test automation, CI/CD, that is slowing down releases. Is that a problem acknowledged in your org? Will you get support for continuing changes and is there an understanding of what is a good enough level?
Would a fixed weekly or bi-weekly schedule work? Both devs and QA can plan their work accordingly. For example: devs and QA agree on what to work on next on a Thursday and how to test (acceptance criterias). Dev start development, QA prepare tests (functional and regression). Dev work for a week, tests and feature freezes code next Thursday. QA starts acceptance test on Friday, they ping-pong Fri-Mon-Tue, regression test and full code freeze on Wednesday, release on Thursday. If quality of the code and tooling makes the process smooth enough, then a similar weekly cycle could also be possible.
Gradually increasing test automation could speed up the whole process. Devs and QA can write and maintain automated tests together.
Feature flags could help isolating bugs that are discovered late in the process.
If there are several rounds between devs and QA, then a root cause analysis can help there as well. Are devs and QA aligned on how to test? Are devs testing enough? Is QA giving enough info for devs on the bugs found? Etc.
