Flexibility Provides more flexibility in defining test suites, test dependencies, and customizing test execution flow. Relies on third-party libraries or plugins for generating reports. Reporting Generates detailed HTML reports by default, providing comprehensive test execution information.

Requires additional libraries or custom code to achieve data-driven testing. Data-Driven Testing Built-in support for data-driven testing, enabling tests to be executed with multiple data sets. Relies primarily on annotations for test configuration and doesn't have built-in XML-based configuration. Test Configuration Offers extensive configuration options through XML-based configuration files and programmatic configuration. Requires additional libraries or plugins for parallel test execution. Parallel Execution Built-in support for parallel test execution, allowing tests to run concurrently. Offers a set of annotations for test configuration and lifecycle methods. While both TestNG and JUnit are popular testing frameworks for Java, there are some notable differences : Features TestNG JUnit Annotation Support Provides a rich set of annotations for test configuration, setup, and teardown methods. These reports can be customized and integrated with other reporting frameworks for better visibility into test results. Reporting and Test Output: TestNG generates detailed test reports that provide comprehensive information about test execution, including test results, test timings, failures, and more. This is particularly useful for parameterized testing, where you can test a single piece of functionality with various input combinations. Data-Driven Testing: TestNG's data-driven testing capabilities enable you to test your application with multiple data sets. This flexibility allows you to define test suites, test dependencies, test groups, and more, according to your specific testing requirements. Test Configuration Flexibility: TestNG provides multiple configuration options, including XML-based configuration files and programmatic configuration using Java classes. It supports parallel execution at the method, class, or suite level, enabling faster feedback. Parallel Test Execution: TestNG allows you to run tests in parallel, which can significantly reduce test execution time, especially for large test suites. Annotations like, ,, ,, ,, and allow you to define setup and teardown methods at various levels. Powerful Annotations: TestNG's annotations provide more flexibility and control over test execution compared to JUnit. TestNG offers several benefits over traditional testing frameworks like JUnit: 1. Assertions help in verifying the correctness of test results and identifying failures. TestNG Assertions: TestNG provides a rich set of assertion methods that allow you to validate the expected behavior of your application under test. This is useful for testing various scenarios with different data sets. Data-Driven Testing: TestNG supports data-driven testing, where you can supply different sets of test data to a test method and execute it multiple times with different inputs. You can define test suites, test groups, test dependencies, and more, allowing you to customize and control the test execution flow. Flexible Test Configuration: TestNG provides various configuration options through XML or Java-based configuration files. This can significantly reduce test execution time and provide faster feedback. Parallel Test Execution: TestNG supports parallel test execution, allowing you to run tests in parallel on multiple threads or even on multiple machines. Annotations provide a way to define pre- and post-test actions, setup and teardown methods, and more. Annotation-based: TestNG allows you to use annotations to define test methods, configure test execution, and manage test dependencies. 8.4 Data-Driven Testing with Selenium and TestNG 9.8.2 Writing Selenium Test Cases with TestNG.2.1.3 Test Dependency - DependensOnMethods.
