TestNG Unit Tests

TestNG is a testing framework inspired from JUnit and NUnit, but introducing some new functionalities that make it more powerful and easier to use.

#What is TestNG?

TestNG is a Java-based unit testing framework designed to support various types of tests, including functional, end-to-end, integration, and more. It is an open-source tool that provides many features and functionalities to help developers create and run tests effectively.

#TestNG Key Features

Most recognizable TestNG features include:

  • Annotations: TestNG uses annotations to define test methods, configure test instances, and manage test execution flow.
  • Test Configuration: TestNG provides various configuration options, including test grouping, data-driven testing, and parallel test execution.
  • Reporting: TestNG generates detailed HTML reports to help developers analyze test results and identify issues.
  • Data Providers: TestNG allows developers to use external data sources, such as CSV or Excel files, to provide test data.
  • Test Dependencies: TestNG supports test dependencies, which allow developers to define test execution order based on dependencies between tests.
  • Listeners: TestNG provides a listener interface that developers can use to customize test behavior.

#TestNG Use-Cases

Some of the TestNG use-cases are:

  • Unit testing: TestNG is primarily designed for unit testing, and it provides many features to help developers create and run unit tests effectively.
  • Integration testing: TestNG also supports integration testing by allowing developers to configure test execution flow and use external data sources.
  • End-to-end testing: TestNG can also be used for end-to-end testing by defining test dependencies and grouping tests based on their functionality.

#TestNG Summary

TestNG is a Java-based unit testing framework that provides various features and functionalities to help developers create and run tests effectively, including annotations, test configuration options, reporting, data providers, test dependencies, and listeners. It can be used for unit testing, integration testing, and end-to-end testing.
