Unit Testing

General info

TestNG is a testing framework for the Java programming language inspired by JUnit and NUnit

TestNG is similar to JUnit and NUnit but with newer functionalities such as: annotations, test that your code is multithread safe, flexible test configuration, support for data-driven testing (with @DataProvider), support for parameters, powerful execution model (no more TestSuite) and more... It's also designed to cover all categories of tests unit, functional, end-to-end, intergration... etc is aUnit testing framework for C# and .NET is a free, open source, community-focused unit testing tool for the .NET Framework. It is used to test C#, F#, VB.NET and other .NET languages. and works with ReSharper, CodeRush, TestDriven.NET and Xamarin. It is part of the .NET Foundation,
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.


Yes is part of the xUnit family of frameworks
Allows testing code execution on the client, such as a web browser


The scope of testing with testNg is wide and you can test various front-end functionalities and behaviours with it


You can test various front-end components independently since it is a Unit testing framework
Allows testing the bahovior of a server-side code


You can test server-side functionalities and behaviours with TestNg


You can test various back-end components independently since it is a Unit testing framework
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test


Fixtures are inbuilt into testNG, these are the annotations which are: @BeforeSuite, @AfterSuite, @BeforeTest, @AfterTest, @BeforeGroups, @AfterGroups, @BeforeClass, @AfterClass, @BeforeMethod, @AfterMethod


It contains class fixtures which are setup once pertest class
Group fixtures
Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests.


You can use various fixtures to setup environments for group tests

Yes contains collection fixtures which allow you to share context among many tests
Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way.

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)


By Use of an external library like mockit which intergrates well with testNG

Allows organizing tests in groups


Multiple test cases can be grouped more easily by converting them into testng.xml file, in which you can make priorities which test case should be executed first
