TestNG, by default, generates reports for test execution, which includes HTML and XML output. TestNG supports Group Test, which dispatches methods into portions and performs groupings of test methods. Junit does not support Dependency Testing if initial tests fail, the subsequent test will also be marked as a fail. TestNG supports Dependency Testing if initial tests fail, subsequent tests will be skipped. returns List and is passed into the class constructor as an argument for parameterized testing. In Junit, and annotations are used to provide parameter value for the unit test. In TestNG, or XML file is used to provide a parameter for parameterized testing. Time test is used to define if the unit test takes longer than the specified time if yes, the test will be terminated. Timeout is to terminate a test that takes a longer time. JUnit uses annotation for ignoring Test cases.Įxception test is used to check which exception is thrown TestNG uses = ArithmeticException.class). TestNG uses annotation with a Boolean parameter enabled for ignoring Test cases. In JUnit, Test Suite is run using and annotations. TestNG uses an XML file to run Suite test. Uses and for method level and and for class level. JUnit initializes and cleanups at two levels, before and after each method and class. Uses and at method level and and for class level. TestNG initializes and cleanups at two levels, at method and class levels. Let’s see some more differences between TestNG vs JUnit through a comparison table for clear understanding: TestNG Both TestNG and JUnit use 1000 seconds for a timeout.JUnit does not support only the Dependency Test. Both JUnit and TestNG support Annotations, Suite Test, Ignore Test, Exception Test, Timeout, Parameterized Test.For setting up a Local environment for JUnit and TestNG, JDK should be installed in the machine.JUnit is developed by Erich Gamma and Kent Beck, whereas Cedric Beust creates TestNG.JUnit is an instance of xUnit Architecture, whereas TestNG is similar to JUnit, but it is not a JUnit extension.JUnit is present in 62% of projects, and TestNG being at 20 th position present in 6% of projects.By default, TestNG provides XML and HTML based reporting.TestNG has XML based test configuration and is data-driven.JUnit shows test progress in the green bar if the test case passes, turns red if it fails.TestNG supports parallel testing, Load testing, partial failures, and multi-threaded testing.Test groups in TestNG compile tests to run all ‘front-end’, ‘fast’, ‘database’, ‘slow’ tests.JUnit tests can be organized as test suites with test cases and also test suites.JUnit can be run automatically, check their own results, and provide immediate feedback, whereas TestNG has run-time configuration flexibility.TestNG separates compile-time and run-time configuration.JUnit allows writing codes faster, which improves quality.TestNG supports testing of integrated classes, no need to create a test instance.JUnit uses assertions for testing results expected by the business.TestNG uses more Java and Object-Oriented features.TestNG and JUnit both support annotations.TestNG is an open-source testing framework, NG representing NextGeneration and JUnit also an open-source testing framework.
