FEST is a collection of APIs, released under the Apache 2.0 license, which mission is to simplify software testing.
Modules
FEST is composed of various modules, all of them can be used with TestNG or JUnit.
Swing Module:
* DSL-oriented API for functional Swing GUI testing
* Simulation of user-generated events and reliable GUI component lookup
* Easy-to-use and powerful API that simplifies creation and maintenance of Swing GUI functional tests:
dialog.comboBox("domain").select("Users");
dialog.textBox("username").enterText("alex.ruiz");
dialog.button("ok").click();
dialog.optionPane().requireErrorMessage()
.requireMessage("Please enter your password");
* Ability to take screenshots of failed GUI tests and embed them in a HTML test report
The Eclipse Memory Analyzer is a fast and feature-rich Java heap analyzer that helps you find memory leaks and reduce memory consumption.
The Memory Analyzer was developed to analyze productive heap dumps with hundreds of millions of objects. Once the heap dump is parsed, you can re-open it instantly, immediately get the retained size of single objects and quickly approximate the retained size of a set of objects. The reference chain to the Garbage Collection Roots then details why the object is not garbage collected.
Using these features, a report automatically extracts leak suspects. It includes details about the objects accumulated, the path to the GC Roots, plus general information like system properties.
Testability-explorer is a tool which analyzes java byte-codes and computes how difficult it will be to write unit-test. It attempts to help you quantitatively determine how hard your code is to test and, where to focus to make it more testable.
Test metric tool can be used:
1. As a learning tool which flags causes of hard to test code with detailed breakdown of reasons.
2. To identify hard to test hair-balls in legacy code.
3. As part of your code analysis-toolset.
4. As a tool which can be added into continuous integration that can enforce testable code.
TestabilityExplorer.org records the testability scores for many open source and commercial Java libraries.
The compiled bytecode for the library is analyzed and metrics are calculated for the testability of individual classes. Those classes fall into one of three categories - 'excellent', 'good' and 'needs work'. Generally speaking, injectability, mockabiliy and composition are good, and static state is bad. Figures are recursively calculated, but only inside the jar in question.
The metrics are a calculation of the skill of the development team in making their classes testable. You cannot use these metrics to say that Tomcat is better than Jetty or vice versa, as the features of each are not taken into account. These metrics will also not tell you whether a particular library will be easy to use or not. It just tells you how dedicated the development team was to making testable software. As we track the changing figures overtime, we can see whether the team in question was dedicated to improvement or not.
JMeasurement is a free and simple java api for monitoring runtime and usage (count, parallel activation, last activation) of user defined points in java production code. It is simple to use and extended. JMX is supported.
Stopwatch was ment to replace System.currentTimeMillis() calls, match like Log4j replaced System.out.println() calls. To see how it does that go to Quick Start page.
Profiler4j is an open-source CPU profiler for Java. To get started, just follow the tutorial or see some screenshots.
Notice that this project is in beta stage and still have some bugs. However, as far as I know, it is fairly stable with typical applications such as Tomcat and JBoss. A final hint: if you develop in JDK1.4 or 1.3, please see this FAQ.
DJProf is an experimental Java profiling tool which employs AspectJ to insert the necessary instrumentation for profiling rather than, for example, the Java Machine Profiler Interface (JVMPI). DJProf can be used to profile Java programs without modification (i.e. there is no need to recompile them for profiling) and does not require the user to have any knowledge of AspectJ. The Load-Time Weaving capability of AspectJ is utilised to make this possible. The tool (including its source code) is release under a very straightforward (and unrestrictive) license for the benefit of all.
