  • More than 150+ Ajax-enabled components available
  • Support to Java Persistence API

Java Testing Tools

5. JRat

The fourth tool Java Runtime Analysis Tool, widely known as Jett, is used as a testing tool for Java applications. It is an open-source platform that helps in determining the application’s execution and performance measurements. It identifies potential risks and analyses data using its pre-built desktop application.


  • Is an open-source profiling tool
  • Supports a wide developer community
  • Improves framework support
  • Allows high-level profiling functionality
  • State of art heap analysis tool
  • Can perform runtime analysis for a remote machine

6. IntelliJ IDEA 13.1

IntelliJ IDEA will always act as a good friend for your application development. When you are busy writing the code, IntelliJ Idea will be busy creating the class references, flow execution, decision tree, fields, methods and much more.  Using this functionality you can quickly navigate through your code and have an error analysis done in no time.

Any of the recent IDE’s will provide you more or less similar functionality, but IntelliJ is the only one that will present you with a deep static code analysis allowing you to focus more on your creativity.


  • Smart completion of your code
  • Data flow analysis
  • Re-factoring
  • Duplicate detection

7. Apache ANT

Apache ant is a popular and traditional built tool since its launch. Apache ANT is an open-source tool for Java developers provided by Apache Software Foundation. The tool is known to automate your process of software building which is achieved in easy steps.

Gradle includes a declaratively modeling of your difficulty domain making use of strong and expressive domain-specific language (DSL), which is implemented in Groovy and not XML, unlike Apache Ant. Because Gradle is a JVM native, it allows you to write custom logic in the language you’re most comfortable with, be it Java or Groovy.


  • Can create multiple APKs for your app
  • Re-usability of code and build process
  • Integration customized to the android studio.
  • Integrated SCM
  • Jenkins integration environment
  • A good number of plug-ins available

9. Mockito

Are you dealing with advanced framework integration? Then Mockito is a tool you should search for. Mockito offers you a mocking framework that is used by people looking out for unit testing their java application. Just as the name, it follows building a fake mock-up for testing purposes.

Mockito allows you to define classes as well as in interfaces that support test espionage and not just mock-ups. It also offers a good void method handling so you need not write separate code for the same.  The only drawback being its maintenance issue.
