Multi-tasking is an evil that reduces our effectiveness. It is true for developers but also for teams. In this blog post, I demonstrate this with the newsletter mailing simulation. It visualizes why multi-tasking takes more time than doing one task at a time. Stop starting, start finishing, and beat the evil of multi-tasking.
I wrote this how-to blog post for myself to sort out how to get code coverage for C# in Azure DevOps' build pipelines. There are many blog posts about this but this one guides how to get reports even if there are many unit test projects in Visual Studio solution.
We usually estimate with ideal days. But we shouldn't because estimating with story points is faster and more accurate. That is not just my feeling, researches tell also so. In this blog post, I've written the reasons for it.
Even if it is already the end of January I still want to summary my past year. After one year at the latest, it is nice to read for yourself how 2019 went and compare it to 2020. Keywords about what I did and learned most in 2019 are Azure, Azure DevOps, and scrum master.
We often talk about mocks, even if should use more precise terms like stub, fake and mock. Correct term for these is test double. In this blog post I introduce these different test doubles with code examples.
Unit tests are a powerful and crucial part of programming. But it isn't enough if we want to know better if our code works. Complementing unit tests with service-level/integration and UI/end-to-end tests will make us know that our code really works. The test automation pyramid tells what is the good ratio between different tests.
Refactoring is a key factor to get high code quality. Too often we end up in a situation when refactoring is already too difficult. By refactoring constantly we can avoid that trap and keep our code clean.
