Key Difference Between TestNG and JUnit

JUnit and TestNG are the most popular Java frameworks. Inspiration for TestNG comes from JUnit and NUnit. TestNG vs. JUnit, contemporary Java testing frameworks. Framework annotations and coding vary by feature. TestNG outperforms Junit in parameterized, suite, and dependency testing.

Unit testing ensures the application functions properly. Compare important features, differences, and how TestNG and JUnit vary.

TestNG vs JUnit Comparison Table

A comparison table shows how TestNG and JUnit, two popular Java testing frameworks, differ:

FeatureTestNGJUnit
Annotation SupportRich set of annotations for test configuration and parallel executionAnnotations for test setup, teardown, and test execution
Test ConfigurationProvides more flexible and extensive test configuration optionsRelatively simpler test configuration options
Dependency TestingSupports test dependencies and prioritizationLimited support for dependency testing
Parallel ExecutionBuilt-in support for parallel test executionLimited support for parallel test execution
Parameterized TestsSupports parameterized testsSupports parameterized tests with @Parameter annotation
Grouping TestsAllows grouping of tests for better organizationAllows test grouping with @Category annotation
Listeners and ReportersProvides listeners and reporters for customizing test execution and reportingSupports custom listeners, but not as extensive as TestNG
Data-Driven TestingBuilt-in support for data-driven testingLimited support, may require additional libraries for data-driven tests
AssertionsSupports a wide range of assertionsProvides a standard set of assertions through the Assert class
