In this paper, we present a new pattern-based GUI testing (PBGT) approach that formalizes the notion of UI Test Patterns, which are generic test strategies to test UI patterns over their different implementations. The PBGT approach is evaluated via 2 case studies. The first study involves 2 ...
However, due to nature of the Visitor pattern, the implementation will be the same, so in most cases, it would require us to copy-paste the boilerplate code from other, already existing element: public class JsonElement extends Element { // ... public void accept(Visitor v) { v.visit(...

; writeln($interpreter->interpret('book title 3')); writeln(''); writeln('test 6 - invalid request with nuo numeric book number'); writeln($interpreter->interpret('book title one')); writeln(''); writeln('END TESTING INTERPRETER PATTERN'); function writeln($line_in) { echo $line_in...
Favour testing expected behaviour rather than the implement Normally a lot of mocking points to bad abstraction in your code. What people see here is a weakness in TDD but it is actually a strength, more often than not poor test code is a result of bad design or put more nicely, well-...
The builder pattern is used to create complex objects with constituent parts that must be created in the same order or using a specific algorithm. An external class controls the construction algorithm. Example // Let's assume that Dialog class is provided by external library. // We have only...

I could set up the database for those test inputs on each test run, but there's an easier way. Let's just use a fake database that can be more easily controlled in testing scenarios by using the Repository pattern to mediate between the application's domain model and the da...
