JUnit framework is a Java system used for performing unit tests on code. By testing the code after each change, developers can be consoled that changing a small amount of code does not break the bigger system.

Without unit testing tools like JUnit, retesting can be an inaccurate and time-consuming process. By permitting the testing procedure to happen habitually and automatically, you can keep software coding mistakes at the very least.

Creating the JUnit test cases, yet, can be a troublesome procedure requiring information of precisely what the code does and how it should be performed.

You should precisely make the unit tests performed by JUnit framework to guarantee that the tests thoroughly check the code similarly as it would keep running in the real world.

Generally, JUnit is an open source unit test framework and used to test small/large units of code. To run the JUnit framework test you don’t need to make a class object or characterize the primary strategy.

JUnit gives a declaration library which is utilized to assess the test outcome. Annotations of JUnit are utilized to run the test technique. JUnit is additionally used to run the automation testing suite having numerous test cases.

What is JUnit Testing?

JUnit is a testing tool for the Java test language. It is extremely useful when you need to test every unit of the project during the SDLC.

Why you require JUnit testing tool?

• It discovers bugs early in the code, which makes our code more dependable.
• JUnit java is valuable for developers, who work in a test-driven condition.
• Unit testing causes a developer to read code more than writing.
• You develop more bug-free, reliable and readable code which builds certainty during development.

Features of JUnit Test Framework:

JUnit java testing frameworks provide the accompanying vital features:

• JUnit classes
• Fixtures
• Test runners
• Test suites

Advantages of JUnit Framework:

• It’s utilized to test a current class. Assume, if we have Calculation class at that point, we have to compose CalculationTest to test the Calculation class.
• Utilizing Java JUnit test, we can save testing time.
• Progressively, in the web application development, we actualize JUnit test cases in the DAO classes. DAO classes can be tested without a server.
• With JUnit, we can likewise test Struts/Spring applications; however, more often than not we test just DAO classes. Indeed, even at times benefit classes likewise tested utilizing JUnit test suite.
• Utilizing JUnit, if we need to test the application at that point the server isn’t required so the testing turns out to be quick.

The vast majority of the developers utilize JUnit as it is simple and does not require much push to test. A simple green or red bar will demonstrate the real outcome of the test. JUnit makes life simple as it has its own particular arrangement of libraries and explanations. Here we, at TestOrigen have the best unit tester’s team, who is capable of performing all types of Unit testing including JUnit framework.
