Java Interactive Profiler
The Java Interactive Profiler (JIP) is a code profiler for Java. It features the ability to turn the profiler on and off at run time as well as the capability to filter out classes and packages.
Java2SD contributes to the area of tools for generating sequence diagrams in an automatic way. To increase the flexibility and interaction with other applications, the developed application is able to export the generated diagrams to multiple formats, allowing its visualization by diverse tools.
JBI Mock Framework
The JBI Mock Framework is a set of classes allowing developers to test JBI components at a unit level, mocking out the Normalized Message Router (NMR). Using the mock classes, developers can achieve high test coverage for their JBI Components.
jBixbe lets you debug Java applications on the conceptual level of the Unified Modeling Language (UML) at which they are designed and makes it possible to find not only simple bugs but also weaknesses and inefficiencies in application design. It shows the big picture of your application so you can recognize classes and objects, and their relationships and interaction. Different view levels support top-down debugging and simplify debugging of multi-threaded applications. Source code debugging has been fully integrated into the object-oriented visualization.
(commercial) JIRA Client is a desktop client for the Atlassian JIRA issue tracking system. JIRA Clients allows users to work with issues anywhere and save time by using an interactive interface for issue tracking. Key features: an offline mode with later synchronization; a three-pane main window that shows filters with counters, a list of issues, and details of a selected issue; a query builder that allows you to build any filters with and, or, and not operations; and query counters, which immediately show how many issues satisfy any given filter.
enables you to understand how much space the packages and classes consume in your Java class path. And it can help you find class paths problems
(commercial) a Java unit testing tool that automatically tests any Java class, JSP, or component without requiring you to write a single test case, harness, or stub. With the click of a button, Jtest automatically tests code construction (white-box testing), tests code functionality (black-box testing), and maintains code integrity (regression testing)
a static Java source code analyzer that detects locking and threading issues, performance and scalability problems, and checks complex contracts such as Java serialization by performing type, data flow, and lock graph analysis
(commercial) a static source code analysis tool for ANSI C that reduces your organizational exposure to risks from latent software problems by automatically identifying problems at their source -- in the C source code prior to compiling or executing programs
provides a simple yet flexible mechanism to output log statements to a file or to an OutputStream
MoMEUnit is an instance of the xUnit architecture for unit testing of J2ME applications. It is derived from the JUnit framework. It is only CLDC 1.1 compliant. It overcomes the lack of a reflection API in the J2ME MIDP API and supports main features of the JUnit framework such as ease of development and running of tests, sharing of fixtures among different tests, the ability to perform simultaneous test runs, and much more. The results of tests are displayed with a progress bar, statistics, and lists of failures or errors with detailed messages for each test.
PIT is a fast bytecode based mutation testing system for Java that makes it possible to test the effectiveness of your unit tests.
PMD is a Java source code analyzer. It finds unused variables, empty catch blocks, unnecessary object creation, and so forth.
Quality Assurance Tester
developed specifically for testing products running across a wide variety of hardware and software platforms
The RDVIS tool helps programmers pin-point the sources of cache misses and poor temporal locality in their source code. The visualization often directs the experienced programmer towards the necessary program transformations within a few minutes. The tool consists of two parts: a GUI that visualizes the low temporal locality patterns, and a patched GCC compiler to extract the low-locality patterns from programs.
Rehersal is a testing framework for Scala. It replaces the built-in SUnit functionality. It uses Expectations rather than Assertions, with real boolean operators. Tests can have any name, with any punctuation.
(commercial) the combination of Apache Tomcat with a nice, clean Swing GUI. It provides an easy way to create and test JSP and Servlet Web applications. It records every JSP/HTTP activity so that every possible bug can be corrected immediately. Schroedinger can be used in personal mode, which prevents others from using its JSP Server while you develop the application
STclass is a unit testing framework comparable to JUnit and its clones, but based on runtime evaluable contracts as defined by B. Meyer in the Design by Contract approach. It implements runtime evaluable contracts and contract based class level unit testing; inheritance of contracts and tests is handled. The framework generates reports in XML, and postprocessing tools produce nice HTML reports; using the JIP profiler, a statisitic and profiling analysis can be made during the test, and its resuts are added to the HTML report.
Testar is a tool designed to reduce the time spent running Java unit tests. It runs on top of JUnit and automatically selects individual tests to run based on what tests previously succeeded and what changes you have made to your code since then.
