Acceptance Testing: Blaming the Tools

software-development-2-logo

About 5 years ago I was on a project to build a system for collateral management. The system was connected to a large financial network, and got its instructions through standardized financial messages. This project was run in waterfall style, with lots of restrictions on collaboration between disciplines. Without to digress in details on this, I do still think it’s ...

Using Matchers in Tests

Gone are the days when we were forced to write way too many assertion lines in our testing code. There is a new sheriff in town: assertThat and his deputy: the matchers.

Major disadvantage of this is that integration tests can take much more time to execute and because no one likes to wait long time every build – tests are just skipped with -Dmaven.test.skip=true flag In order to execute ...

Recently I’ve been working with a project heavily using JBoss Drools. I am not Drools expert – I am not also very convinced to this framework, or maybe only to particular use case in this project – and I found it quite difficult to write simple, maintainable unit tests for Drools based business rules. That’s how junit-drools was born – ...

Imbibing the Fluency of Mockito

I recently found myself writing some code to integrate two disparate platforms. One of these systems is Java based and the other, while not written in Java, offers a Java API.

Sometimes TDD Requires a Hammer

software-development-2-logo

While there are myriad mocking libraries available for the Java platform, only a select few of these nifty frameworks is capable of mocking the non-mock-friendly modifiers of static and final. Static (or class) methods, while handy for factories, become a nuisance for a framework like Mockito, however, with the inclusion of PowerMock, you’ve got yourself a proverbial hammer. As I ...
