It amazes me how many great tools you can find on the web! In this post I describe 4 of them. I hope you find them useful.
1000 words about testing of REST. Nothing impressive, simply a dump of my thought regarding this subject.
Recently I've spent some time browsing the Net and learned about some new stuff ("new" meaning "new to me") that I would like to share with you. Let us have a look at HavaRunner, some nice TestNG reports, and TDD Katas.
Sooner or later your CI server will became very busy, and your frustration will grow because of increasing wait time for each build. One thing you can do to improve the situation is to avoid running jobs when there is no need to do so.
I use Jenkins + Maven + SVN in this example, but you can use this "tricks" also when using different technologies - Gradle, Git etc.
I'm happy to announce the arrival of my new book! :) It is called "Bad Tests, Good Tests" and is all about writing high-quality tests.
I can't remember when it started but since some time I was collecting "interesting" pieces of test code. By "interesting" I mean the ones that could be well improved. After some time I noticed there are some (anti)patterns, some typical bugs, or rather imperfections which I observe frequently when reviewing test code.
I try to write my tests so they fulfil some basic requirements. They should verify some important part of the system. They should survive refactorings. They should be readable, clear and concise, so you can read them like documentation. They should be fast.
Today I have learnt about Ishikawa diagram (AKA fishbone diagrams, herringbone diagrams, cause-and-effect diagrams, or Fishikawa). And I started to wonder whether it makes sense to use it to diagnose the issues related to the production of software. (I will not explain Ishikawa diagram in this post, so please have a look at Wikipedia description if it does not ring any bells for you).
Recently I have learned one (very useful!) trick, that I wanted to share with you. It occurred that it is very simple to create PDF files with custom embedded fonts.
One of my readers asked a question whether he should rather use test doubles (mocks) or Test Data Builders to create objects (collaborators) for testing purposes. I've decided to write down some thoughts in form of this blog post. I hope it makes things more clear.
