What is JUnit? What are the attributes of JUnit?

JUnit is an open-source unit testing framework for Java. It is helpful for Java Developers to write and run tests that they can repeat. The name implies that it is used for unit testing a small chunk of code.

Those who adhere to the test-driven development methodology must write and execute unit tests before any code.

When you are finished writing your code, you should run all the tests, and they should pass. Whenever new code is added, you will need to re-execute all test cases to ensure that nothing is broken.

Before we dive into JUnit testing, it’s important to understand what unit testing is.

Unit testing is the process of testing a small piece of code or logic to make sure that the output is as expected given a specific set of input data and conditions. Usually, unit tests are expected to be independent of other tests.

Unit tests are not adequate for testing complex interfaces with another application or third-party/external service. A unit test targets a small unit of code, such as a method or class.

The importance of unit testing can be understood by these points:

  • Unit testing is used to identify defects as early as possible in the software development cycle.
  • Unit testing will make us read our code. For example, a developer may start spending more time reading than writing.
  • Flaws in the code design affect the development system. A successful code makes a developer more confident.

Why do you need JUnit testing?

  • It helps us discover errors in the code earlier, which helps make our code more reliable.
  • JUnit is useful to developers working in a test-driven environment.
  • Unit testing encourages developers to read code more than write it.
  • You create code that is more readable, reliable, and free of bugs, which builds confidence during development.

Approach to Unit Testing

Unit testing can be accomplished through two approaches:

  1. Manual testing
  2. Automated testing

In both approaches, the workflow remains the same:

  1. Creating a test case
  2. Reviewing it
  3. Rework if necessary.
  4. Execute the test case
  5. Analyze the test results

We talked about JUnit earlier. JUnit is a free tool for writing and running tests in the Java programming language. It is a highly renowned unit testing framework.

The Attributes of JUnit

The attributes that JUnit is packaged with are listed:

  • There is a huge list of Annotations that identify, execute, and support many features for the test methods.
  • There are Assertions that check to make sure the results are what was expected.
  • It has a Test Runner that you can use to run the tests.
  • JUnit is a simple testing framework that you can use to write small test cases quickly.
  • JUnit tests help you write independent modules, which in turn improves coverage and quality.
  • It not only lets developers easily create and run tests but also gives them a clear and clean report that eliminates the need for them to look through the reports and test results’ path to find the results.
  • As soon as the test fails a verification checkpoint, the green-colored progress bar will alert you in red, but until the test is sailing through smoothly, you may relax.
