How do you re-run failed test cases using TestNG?

2

Hey Alex,

To rerun failed test cases using TestNG, you can use the following steps:

  • Create an XML file that includes the names of the test methods you want to rerun.
  • Use the tag to specify the test methods you want to rerun.
  • Use the tag to specify the name of the class that contains the test methods.
  • Use the tag to include the test methods you want to rerun.
  • Use the tag to specify the groups of test methods that you want to rerun.
  • Use the tag to specify the name of the testng.xml file you want to use to rerun the test methods.

To know more about how to re-run failed test cases using TestNG, follow this guide and learn various methods.

To rerun failed test cases using TestNG, you can follow these steps:

  1. Create an XML file that includes the names of the test methods you want to rerun.

  2. Use the <methods> tag to specify the test methods you want to rerun.

  3. Use the <class> tag to specify the name of the class that contains the test methods.

  4. Use the <include> tag to include the test methods you want to rerun.

  5. Use the <groups> tag to specify the groups of test methods that you want to rerun.

  6. Use the <run> tag to specify the name of the testng.xml file you want to use to rerun the test methods.

Building on Dipen’s approach, you can also use the RetryAnalyzer interface. This involves creating a custom RetryAnalyzer class that implements the IRetryAnalyzer interface provided by TestNG. With this class, you can specify the logic for re-running failed test cases, including setting the number of retry attempts and conditions for when a test should be retried. This approach offers more fine-grained control over which tests are re-run and how many times they are retried.

Additionally, you can use the @ Listeners annotation in TestNG to re-run failed test cases. By creating a custom listener class that implements the IAnnotationTransformer interface, you can intercept test methods and apply logic to re-run failed tests. This method provides a dynamic way to manage re-runs, as you can define the re-run logic in the listener class and apply it across multiple test classes or methods. This adds flexibility and can simplify the maintenance of your test suite.
