TestNG Introduction Tutorial:
What is TestNG:
- TestNG is a unit test framework.
- TestNG framework means Next Generation testing framework.
- It is inspired from JUnit & NUnit by adding new functionalities which made TestNG more powerful than other unit test frameworks.
- TestNG cover all unit, functional, end-to-end, integration etc. testing categories.
- TestNG gives the developer the ability to write more flexible and powerful tests.
- TestNG gives the ability to produce HTML Reports of execution.
- It provides an HTML report of all test cases execution.
- Data input can be easily provided.
- Generate logs.
- The set of test cases is going on.
- Supports annotations.
- Support for parameters.
- Skipping a test.
- Parallel execution.
- Test priority and grouping.
- Use of listeners to capture snapshot, error logging.
- Ways to set time for advance XSLT, boundary report, etc.
- Data parameterization is possible.
- The testers can execute several test cases at one time. In this XML file, users will have to specify the number of classes and test-related cases they want to execute.
- TestNG can also be used to run failed test cases.
- TestNG allows the examiner to run and run a script in multiple browsers.
- With the help of @Test, you can disable or bypass a particular test case with the help of @Test (enabled = false).
- Able to define priority order in @Test annotation.
Test case writing in TestNG:
- Step 1 : Write the business logic of the test using Selenium.
- Step 2 : Enter the test annotation in the code to provide additional parameter’s.
- Step 3 : Add information about your test (e.g: class names, methods names, group names etc.) in a testng.xml file to execute script.
- Step 4 : Run as TestNG.
Benefits of TestNG over JUnit:
- Advance and easy annotation added.
- Execution pattern can be set.
- Concurrent execution of test scripts.
- Test case dependency can be set.
