Since a few weeks the new mockito release candidate is available. So I think it is the right time to place a new post. Here I will show the differences between ArgumentMatcher and ArgumentCaptor. Most developer will first see the ArgumentMatcher and use it. What can be done with ArgumentCaptor is often not seen. With the sample I will show that an ArgumentMatcher should not be used to fetch arguments. For this work there is the ArgumentCaptor. The Matcher should really be used to check if an argument matches or not.

Some time ago, Patrick Smacchia (NDepend lead developer) offered me a NDepend Pro license to play around. NDepend is a tool providing a lot of features. The feature that impressed me from the very start is visualizing dependencies. Not just dependencies from classes to classes, or assemblies to assemblies; no from everything to everything. Like for example all assemblies that use somewhere the method Foo of class Bar. It works for assemblies, namespaces, types, methods and fields.

But, what’s all this fuss about?

Keeping a code base and its design as simple as possible over a long period of time is very difficult. It happens just too quickly that we loose the overview of how things are sticked together. And this is the moment when NDepend with its quick and easy dependency visualization comes to the rescue.

Urs started with the idea and the category “why I like”… So I’ll steal his idea and go further with this category… This might be an expensive blog post because I need to pay license fees to Urs

We adopted machine.specifications for our project approximately one year ago. We compared several context and specification frameworks but the overhead of the competitors was too high for our team. Also didn’t we have a product owner who was willing to write for example Gherkin language. So we decided to go with the developer centric machine specification from Alexander Gross.
