This is part 8, the last instalment of the series called “Functional Java by Example”. The example I’m evolving in each part of the series is some kind of “feed…
In this first installment of Testing with state using GraphWalker, we’ll look at integration testing the persistence layer of a Spring application. So, our tests will target the database and…
This post will demonstrate generating test data using junit-quickcheck. It will focus on practical examples, rather than the theory behind property based testing.
This is part 7 of the series called “Functional Java by Example”. The example I’m evolving in each part of the series is some kind of “feed handler” which processes…
When I explained a piece of code to a colleague during a code review, I realized I had inadvertently implemented a readers-writer lock. So, I threw the code out, replacing…

This is part 5 of the series called “Functional Java by Example”. In previous part we stopped mutating our documents and returned copies of the data. Now, we need to…
This is part 4 of the series called “Functional Java by Example”. In previous part we talked a bit about side effects and I’d like to elaborate a bit more…
Today is my birthday. Yes, it is actually my birthday: May the 15th. So, I thought it would be fun to write about a little algorithmic puzzle I’ve been pondering…
