Java Test Tools

Arquillian - Arquillian from JBoss enables you to test Java business logic in a remote or embedded container. Alternatively, it can deploy an archive to the container so the test can interact as a remote client. No longer does writing a test involve system administration tasks, custom scripts, copy-paste Maven configuration, full builds, test classpath mayhem, looking up resources manually or reliance on coarse-grained, black-box testing. The goal is to provide a simple test harness that abstracts away all container lifecycle and deployment from the test logic so developers can easily produce a broad range of integration tests for their enterprise Java applications. Arquillian can either execute a test case inside the container, in which case the test class is deployed by Arquillian along with the code under test, or hold back the test class so it can act as a remote client to the deployed code. All the developer has to do is write the test logic.

VisualVM - A free visual tool, originally from Sun, to monitor and troubleshoot Java applications. Runs on Sun JDK 6, but is able to monitor applications running on JDK 1.4 and higher. Utilizes various available technologies like jvmstat, JMX, the Serviceability Agent (SA), and the Attach API to get data and uses minimal overhead on monitored applications. Capabilities include: automatically detects and lists locally and remotely running Java applications; monitor application performance and memory consumption; profile application performance or analyze memory allocation; is able to save application configuration and runtime environment together with all taken thread dumps, heap dumps and profiler snaphots into a single application snapshot which can be later processed offline.

Window Licker - An open source framework for the test-driven development of Java systems through the GUI. Provides a high-level API for controlling and making assertions about graphical user interfaces: for Swing and Dynamic HTML (aka "AJAX") including GWT. Deals with the asynchronous nature of GUI and AJAX programming so the tests don't have to; Controls the GUI by sending native mouse and keyboard events; Handles different keyboard layouts; Produces high quality error messages to help you easily diagnose test failures; Easily extensible to cope with new user interface components

Cobertura - Free Java tool to identify which parts of a Java program are lacking test coverage and calculate % coverage; based on jcoverage. Instruments already-compiled Java bytecode; execute from ant or from the command line; generate reports in HTML or XML; shows % of lines and branches covered for each class, each package, and for the overall project. Shows McCabe cyclomatic code complexity of each class, and average cyclomatic code complexity for each package, and for the overall product. Can sort HTML results by class name, percent of lines covered, percent of branches covered, etc. and sort in ascending or decending order.

JProfiler - Java profiling tool from ej-Technologies GmbH. Check for performance bottlenecks, memory leaks and threading issues.

Parallel-junit - Open source small library extensions for JUnit. Extends the junit.framework.TestSuite class by running tests in parallel, allowing more efficient test execution. Because TestResult and TestListener aren't designed to run tests in parallel, this implementation coordinates the worker threads and reorder event callbacks so that the TestResult object receives them in an orderly manner. In addition, output to System.out and System.err are also serialized to avoid screen clutter.

EMMA - Open-source toolkit, written in pure Java, for measuring and reporting Java code coverage. Targets support for large-scale enterprise software development while keeping individual developer's work fast and iterative. Can instrument classes for coverage either offline or on the fly (using an instrumenting application classloader); supported coverage types: class, method, line, basic block; can detect when a single source code line is covered only partially; coverage stats are aggregated at method, class, package, and "all classes" levels. Reports support drill-down, to user-controlled detail depth; HTML reports support source code linking. Does not require access to the source code; can instrument individial .class files or entire .jars (in place, if desired). Runtime overhead of added instrumentation is small (5-20%); memory overhead is a few hundred bytes per Java class.

PMD - Open source static analyzer scans java source for problems. Capabilities include scanning for: Empty try/catch/finally/switch statements; Dead code - unused local variables, parameters and private methods; Suboptimal code - wasteful string/stringBuffer usage; Overcomplicated expressions - unnecessary if statements, for loops that could be while loops; Duplicate code - copied/pasted code - could indicate copied/pasted bugs.

Hammurapi - Code review tool for Java (and other languages with latest version). Utilizes a rules engine to infer violations in source code. Doesn't fail on source files with errors, or if some inspectors throw exceptions. Parts of tool can be independently extended or replaced. Can review sources in multiple programming languages, perform cross-language inspections, and generate a consolidated report. Eclipse plugin.

TestNG - A testing framework inspired from JUnit and NUnit; supports JDK 5 Annotations, data-driven testing (with @DataProvider), parameters, distribution of tests on slave machines, plug-ins (Eclipse, IDEA, Maven, etc); embeds BeanShell for further flexibility; default JDK functions for runtime and logging (no dependencies).

Concordian - An open source testing framework for Java developed by David Peterson. Utilizes requirements in plain English using paragraphs, tables and proper punctuation in HTML. Developers instrument the concrete examples in each specification with commands (e.g. "set", "execute", "assertEquals") that allow test scenarios to be checked against the system to be tested. The instrumentation is invisible to a browser, but is processed by a Java fixture class that accompanies the specification. The fixture is also a JUnit test case. Results are exported with the usual green and red indicating successes and failures. Site includes info re similarities and diffs from Fitnesse.

DBUnit - Open source JUnit extension (also usable with Ant) targeted for database-driven projects that, among other things, puts a database into a known state between test runs. Enables avoidance of problems that can occur when one test case corrupts the database and causes subsequent tests to fail or exacerbate the damage. Has the ability to export and import database data to and from XML datasets. Can work with very large datasets when used in streaming mode, and can help verify that database data matches expected sets of values.

StrutsTestCase - Open source Unit extension of the standard JUnit TestCase class that provides facilities for testing code based on the Struts framework, including validation methods. Provides both a Mock Object approach and a Cactus approach to actually run the Struts ActionServlet, allowing testing of Struts code with or without a running servlet engine. Uses the ActionServlet controller to test code, enabling testing of the implementation of Action objects, as well as mappings, form beans, and forwards declarations.

DDSteps - A JUnit extension for building data driven test cases. Enables user to parameterize test cases, and run them more than once using different data. Uses external test data in Excel which is injected into test cases using standard JavaBeans properties. Test cases run once for each row of data, so adding new tests is just a matter of adding a row of data in Excel.

StrutsTestCase for JUnit - Open source extension of the standard JUnit TestCase class that provides facilities for testing code based on the Struts framework. Provides both a Mock Object approach and a Cactus approach to actually run the Struts ActionServlet, allowing testing Struts code with or without a running servlet engine. Because it uses the ActionServlet controller to test code, can test not only the implementation of Action objects, but also mappings, form beans, and forwards declarations. Since it already provides validation methods, it's quick and easy to write unit test cases.
