Java has always been used as the first language for developing dynamic and robust web applications. It provides the flexibility that developers need to create effective web apps. So, when it comes to unit testing of Java-based web apps, there are minimal Unit Test Frameworks available, such as:

1. JUnit

JUnit has always been the first choice of developers to automate unit testing of a java-based application. It was developed by Erich Gamma and Kent Beck as an instance of xUnit. JUnit was specially developed for scripting and performing repetitive test cases. But, it can also be utilized to automate testing of web applications by integrating it with selenium webdriver.

Prerequisites

JUnit is a java-based framework, but you still need access to a few things for using this framework to its full potential.

  • The latest version of JDK installed on your system
  • Adequate knowledge of application development in an object-oriented programming language like Java
  • Knowledge of setting up the JUnit test environment on your workstation

Benefits of JUnit

JUnit offers several benefits to testers to automate unit testing of web apps:

  • Early detection of defects in code, making the code more readable
  • With JUnit 4, you can easily find the exception in the code, as well as execute test cases generated in the older versions of JUnit
  • Offers a test-driven environment, which forces developers to read the code
  • Allow creating readable and error-free test cases
  • Compatible with Java 5 and other versions of Java programming language

Disadvantages

There is only one major drawback of using the JUnit framework – it is not capable of executing dependency tests. For that, you need to use TestNG.

2. TestNG

TestNG is an open-source testing framework created by Cedric Beust. TestNG covers a wide range of test categories which includes unit, functional, end-to-end, integration. It is being widely used by Java developers to unit test developed web applications. It was designed to overcome the competencies of JUnit. That’s why it is more robust, reliable, and featureful than JUnit. It provides developers with various functionalities, such as grouping, sequencing, and parameterizing, which allow them to create more flexible test cases while eliminating the drawbacks of JUnit and to automate unit tests.

Prerequisites

To install and run TestNG scripts on your workstation, you need the following things that are almost similar to JUnit installation:

  1. Installation of the latest version of JDK on your system
  2. Adequate knowledge of java programming language
  3. Experience in installing and using the latest version of Eclipse on the workstation

Benefits of TestNG

Apart from eliminating the disadvantages of JUnit and other java-based testing frameworks, TestNG offers some additional advantages as well, such as:

  1. Allow developers to run parallel tests across various code snippets
  2. Grouping test cases as per your requirements
  3. Generating HTML report while executing test cases
  4. Set priorities for the unit test by parameterizing the data or using annotations

Disadvantages

There aren’t any such drawbacks of using TestNG unless it doesn’t meet your testing requirements. Also, setting up TestNG on your system takes a little longer than other Java-based testing frameworks.

Both JUnit and TestNG are similar to each other in most cases. However, TestNG is integrated with some advanced features that make it a better option than JUnit. Apart from these two, there are other Java-based Unit Test Frameworks as well, such as Selenide, Serenity, JBehave, etc.
