What is the difference between junit and java

Since both of them are unit testing frameworks, a better in-depth analysis of TestNG vs JUnit will surely help you choose a better framework. Another good reason for going through these differences is for the fellow students and professionals who have not tried their hands on any unit testing framework and are putting their first step in the same field.

Additionally, a better understanding of unit testing will, therefore, come in handy, which is the foundation of these frameworks. With all this said, let's see our index for the tutorial:. Before starting with the differences between TestNG and JUnit, we should understand what is meant by unit testing in brief.

The word " unit " is used very popularly in two major fields: mathematics and budgeting. Similarly, in budgeting, we say " unit " when we want to refer to a single element of which many are available. So literally, the term unit refers to singularity. Therefore, Unit testing means testing the smallest piece of code that is logical and isolated.

Isolating means it does not depend on any other code from any other element. If unit testing happens on non-isolating terms, in that case, the test will fail. Moreover, Unit testing is done by putting the values by the tester and can be associated with the functions of a program or a single module, etc.

What does the unit testing offer us? Unit testing helps in faster development of software, easing out the debugging process and makes the code reusable.

Additionally, for a detailed guide, you can visit our post What Is Unit Testing and What are its benefits? JUnit is a testing framework written in Java. In addition to that, it is beneficial for the tester to write and execute repeatable automation tests.

The framework is very popular in the testing community today. Moreover, for writing the automation tests for the web, JUnit is used quite extensively with the Selenium web driver. The features of JUnit are in a different section. The TestNG framework was released after JUnit and served the same purpose, along with some additional functionalities.

Additionally, the TestNG framework is used for testing and written in Java for the Java programming language. Moreover, the TestNG framework performs unit testing, end-to-end testing, integration testing, etc.

The testNG framework is very powerful. Additionally, you can visit our complete covering all the features of TestNG along with practical examples in Selenium. Now that we have a basic knowledge or overview of unit testing and both of the frameworks, we will categorize the differences into significant features.

Moreover, if you do not know about that feature, I will provide a link to visit a detailed guide for that. Fixtures Allows defining a fixed, specific states of data fixtures that are test-local. This ensures specific environment for a single test. Yes Fixture methods are available through its ClassMethods Module. Yes JUnit contains a setUp method, which runs before every test invocation and a tearDown method, which runs after every test method.

Yes Group fixture methods are supported. Yes You can use setUp and tearDown inbuilt functions as group fixtures. You can use JUnit-quickcheck to generate test data. Licence Licence type governing the use and redistribution of the software. Mocks Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation with other parts mocked when needed.

JUnit does not support mocking internally but you can use a mock framework like Mockito to generate mock objects. Grouping Allows organizing tests in groups. Testing can be done while writing the code. TestNG is more preferred than JUnit because of its flexibility to new languages and ease of usage. It was created by Cedric Beust.

It is also a java framework. Integration testing, Unit testing, and many more testing are supported by this tool. It is more flexible and dependable as compared to the JUnit testing tool. TestNG supports a higher level of annotation, which makes it a more usable tool. It is more powerful than the JUnit platform. It wins over the drawbacks of the JUnit testing tool by doing parallel or simultaneous testing of a program.

It creates multiple instances of the same test class. TestNG saves the time of a developer by making the same class run multiple times of different codes. Dependency checking can be done easily in this tool. TestNG includes core concepts of Junit4 functionality and hence meant for high level and complex integrations tests, whereas Junit is considered for testing each code unit. Each framework has its strengths and weaknesses, and hence one needs to select the test framework according to business requirements.
