Assuming a tester has configured the test environment and a test tool like Selenium, here are the steps I would take to automate the login functionality.
- Test the login manually to understand all the input fields, checkboxes, and buttons on the login screen. Keep a note of which pages the user is redirected to in both successful and failed logins.
- Prepare a test dataset that contains the username and password combinations. The inputs consist of varying lengths and have alphanumeric character sets.
- Develop test cases to test various paths the user might take in a real-world scenario. Note down the expected outputs for each test case.
- In the test tool, configure each test case to be manually invoked, and use the test data prepared in step 2. Record the instances where the actual output doesn’t match the expected result.
- Verify and validate the success/error messages and the redirects after each login attempt.
