Common Mistakes

Hardcoding passwords that may change or cause security risks.

Using environment variables for passwords avoids hardcoding sensitive data and eases maintenance.

Fill both blanks to create a robust test that handles UI changes and waits for elements.

Testing Fundamentals

    driver.implicitly_wait([2])
    button = driver.find_element_by_[1]('submit-btn')
    button.click()

💡 Hint

Common Mistakes

Using less stable locators or too short wait times.

Using 'id' is a reliable locator, and waiting 10 seconds helps handle slow UI loading.

Fill both blanks to create a dictionary comprehension that filters test cases by status.

Testing Fundamentals

filtered_tests = {test: status[1] 'passed' for test, status in test_results.items() if status [2] 'passed'}

💡 Hint

Common Mistakes

Using wrong operators or symbols that break dictionary syntax.

The colon ':' separates key and value in a dictionary, and '==' checks for equality to filter passed tests.
