Key skill for effective communication in testing teams

Which skill is most important for a tester to communicate effectively with developers and stakeholders?

A Using complex technical jargon

B Knowing multiple programming languages

C Writing clear and concise bug reports

D Working independently without feedback

💡 Hint

Think about how testers share problems and results with others.

Clear and concise bug reports help developers understand issues quickly and fix them efficiently. Using complex jargon or working alone can cause misunderstandings.

❓ assertion

Assertion to verify a login button is enabled

Which assertion correctly checks that a login button is enabled in an automated test?

Testing Fundamentals

button = driver.find_element(By.ID, 'login-btn')

A assert button.is_enabled() == False

B assert button.is_displayed() == False

C assert button.text == ''

D assert button.is_enabled() == True

💡 Hint

Check the property that tells if the button can be clicked.

The is_enabled() method returns True if the button is clickable. The assertion confirms this.

Output of test result summary code

What is the output of this Python test summary code?

Testing Fundamentals

test_results = {'passed': 8, 'failed': 2, 'skipped': 1}
summary = f"Passed: {test_results['passed']}, Failed: {test_results['failed']}, Skipped: {test_results['skipped']}"
print(summary)

A Passed: 8 Failed: 2 Skipped: 1

B Passed: 8, Failed: 2, Skipped: 1

C {'passed': 8, 'failed': 2, 'skipped': 1}

D Passed: 8, Failed: 2, Skipped:

💡 Hint

Look at how the f-string formats the output with commas and spaces.

The f-string inserts values with commas and spaces exactly as shown in option B.

Identify the error in this test locator code

What error will this Selenium locator code cause?

Testing Fundamentals

element = driver.find_element(By.CSS_SELECTOR, '#submit')

A AttributeError: module 'selenium.webdriver.common.by' has no attribute 'CSS'

B NameError: name 'By' is not defined

C NoSuchElementException: element not found

D SyntaxError: invalid syntax

💡 Hint

Check if the locator strategy name is correct.

The correct locator strategy is By.CSS_SELECTOR, not By.CSS. Using By.CSS causes AttributeError.

Best practice for organizing automated test cases

Which option shows the best practice for organizing automated test cases in a modern testing framework?

A Group tests by feature and use descriptive test names with setup and teardown methods

B Write tests without assertions to speed up execution

C Put all tests in one file with no setup or teardown to keep it simple

D Use random test order and no grouping to find hidden dependencies

💡 Hint

Think about maintainability and clarity in test suites.

Grouping tests by feature and using setup/teardown improves readability, reusability, and maintenance. Random order without control can cause flaky tests.
