The State of Engineering Productivity in 2024 📊 1) Hybrid is hard Teams who work in hybrid mode have the hardest time. It is tough to create an environment where the playing field is level for everybody: there is less incentive to build a truly remote-friendly environment than in full-remote teams, while at the same time you don’t get the full benefits of co-location. Committing decisively to one of the two extremes might bring better results in terms of productivity — but of course it can be more challenging in other departments....

Approval Tests - Home Unit testing asserts can be difficult to use. Approval tests simplify this by taking a snapshot of the results, and confirming that they have not changed. Interesting approach to testing using Combination Approvals: @Test public void upateQuality() throws Exception { CombinationApprovals.verifyAllCombinations( this::doUpdateQuality, new String []{"foo", "bar", "baz"}, new Integer []{-1, 0, 11}, new Integer[0, 1, 49, 50}); } private String doUpdateQuality(String name, int sellIn, int quality) { /*....

The pernicious effect of having a separate testing team: How Big Tech does Quality Assurance (QA) - by Gergely Orosz The change in the number and type of tests the Visual Studio Team Services experienced after merging the dev and the test teams. Before the merge: end-to-end tests dominated, but unit and integration tests were rare. This flipped after the merge. (Microsoft Dev Blogs) In 2 years, almost all “old” tests from when test was separate from dev, were gone....

A good error message has three parts: The problem – explains that an error has happened; The cause – explains what caused the problem; The solution – explains how to overcome the problem. After you ensure your message contains all these three parts, its time to review it. You need to edit it to ensure it: Is user centred – avoid jargon and words your audience will have an hard time understanding; Is direct – as William Strunk said, “Put statements in positive form....
