Agree with this and the parent comment. For the most part automated tests are for testing for regression. The highest ROI tests for complex projects are end-to-end in my experience - where the gateway interface is the API or UI - because they test an entire flow and can let you know if there is an issue somewhere, ideally with an error that can narrow it down to a specific function or file/module. It does seem like the author is talking about unit tests based on what he/she is saying which can imo have less ROI but they're still not useless. If you have limited resources (don't we all) then start with a developer working on end-to-end tests, it's further away from the code being tested but it's great 'bang for buck', and run them on an automatic schedule - each commit may be overkill because end-to-end tests can take a long time. The second part of the article mentions that stale tests are often not removed. However if running tests using either CI or on a regular schedule and viewing the results everyday, this can't happen, they would be removed or modified quickly. This does raise a valid point that within our industry test results data is often not handled well and is an afterthought. My hypothesis is that this is actually the reason some developers get frustrated with tests or do not see the value or why you may get stale tests not being removed. The problem of poor management of test results data itself (the output from testing) rather than testing itself is the problem. A small plug here but I started tesults.com to address this very problem., integration takes a few minutes if you use a popular test framework. There's a forever use free tier so try it out, and if you need more but don't have or can't get budget but love what it does then send me an email and I'll expand your free tier. The important thing is to try to see if it makes thing better for you and you use it as part of your release management.
