Java FEST – GUI Functional Swing Testing

FEST is a collection of libraries, released under the Apache 2.0 license, whose mission is to simplify software testing. It is composed of various modules, which can be used with TestNG or JUnit.

GUI Functional Swing Testing
This module provides a simple and intuitive API for functional testing of Swing user interfaces, resulting in tests that are compact, easy to write, and read like a specification. Tests written using FEST-Swing are also robust. FEST simulates actual user gestures at the operating system level, ensuring that the application will behave correctly in front of the user. It also provides a reliable mechanism for GUI component lookup that ensures that changes in the GUI’s layout or look-and-feel will not break your tests. FEST makes troubleshooting failures a lot easier. It can take screenshots of the desktop at the moment of a test failure, to make it easier to determine if the failure was due to a programming error or an unexpected environment event. When a GUI test fails, FEST also provides useful information in the failure message, such as a nicely-formatted GUI component hierarchy, allowing developers to quickly inspect the cause of the failure.

Fluent Assertions
This module provides a fluent interface for assertions. FEST’s assertions are incredibly easy to write: just type “assertThat” followed the actual value and a dot, and any Java IDE will show you all the assertions available for the type of the given object to verify. No more confusion about the order of the “expected” and “actual” values.

Fluent Reflection
This module provides an intuitive, compact and type-safe fluent API for Java reflection. It makes Java reflection tremendously easy to use: no more casting, checked exceptions, PriviledgedActions or calls to setAccessible. FEST’s reflection module can even overcome the limitations of generics and type erasure.
