How do I write test cases for browser compatibility?

In writing a test case, you should follow these steps:

1. Create a simple test case and a scenario.
2. To execute the test case, add the test data.
3. Perform a specific set of actions on the AUT.
4. Check the behaviour of the AUT. In this test, check the results, then compare the actual and expected results and assign a pass or fail.
5. Include the precondition and post-condition.
