It was only a few years ago that I did a gig at a financial company and when I asked about writing tests I was told “we don’t have time!”. My response of “how will I know it works?” was met with silence. (I wrote tests and finished well ahead of schedule. Then left.)Post details

Writing more than the min amount of code to make your test pass damages the specificity and sensitivity of your overall test suite. Specificity: bug in your code = RED tests Sensitivity: feature is working = GREEN test (protects against regressions) codingitwrong.com/2020/12/23/why…arkangelofkaos (@arkangelofkaos)Wed, 08 Dec 2021 09:20 GMT

Same with automated testing prior to deployment. This is a good thing though. Those hard problems were always there, you just never had time to look for them due to all the simpler issues taking up all your time.Post details
it's a bit counterintuitive, but the better-instrumented and the more mature your systems are, the fewer problems you'll find with automated alerting and the more you'll have to find by sifting around in production by hand. twitter.com/arclight/statu…Charity Majors (@mipsytipsy)Tue, 09 Nov 2021 22:13 GMT

Unit testing requires significantly less skill, time investment, and infrastructure than any other form of testing and almost any other form of verification. So anybody can pick it up and apply it to any project. That's why it's the go-to technique

One thing I've wondered about is why software folks so often use unit testing as their go-to testing technique. When I've worked at companies that ship few enough bugs that it would be considered a failure to have one serious bug in a year, unit testing has been a last resort.Dan Luu (@danluu)Tue, 11 May 2021 17:42 +0000
