A test analyst is testing a function that calculates the area of a rectangle. The analyst wants to use random testing to generate inputs. Which of the following is a valid approach?

Use a metamorphic relation: if length is doubled, the area should double.

Use a checklist of common area calculation errors.

Generate random numbers for length and width, and compare the output to a known formula (length * width).

Generate random positive numbers for length and width, and verify that the output is positive.

A test analyst is preparing to use crowd testing for a new application. The analyst wants to ensure that the crowd testers focus on high-risk areas. Which of the following is the most effective way to guide the crowd testers?

Ask the crowd testers to use random testing without any guidance.

Provide a detailed test script for each tester to follow.

Require each tester to create a test charter before starting.

Provide a checklist of areas to test, such as login, payment, and error handling.

A test analyst is considering using random testing for a new application. The analyst is concerned that random testing may not cover important scenarios. Which of the following is the most effective way to address this concern?

Use random testing in combination with other techniques, such as checklists and exploratory testing.

Use random testing only for non-critical features.

Use random testing only after all other testing is complete.

Use random testing exclusively to ensure unbiased coverage.

A test analyst is planning an exploratory testing session for a new e-commerce checkout flow. The session is time-boxed to 90 minutes. The analyst wants to ensure that the session covers high-risk areas such as payment processing, discount calculations, and error handling. Which approach best aligns with session-based testing principles?

Skip planning and start testing immediately to maximize the time spent on actual exploration.

Create a test charter that states the mission, the areas to explore (payment, discounts, error handling), and the time limit, then explore freely within that scope.

Use random testing to generate random clicks and inputs in the checkout flow without any predefined focus.

Write a detailed test script covering every step of the checkout flow and execute it step-by-step.

What is the main purpose of using metamorphic relations in metamorphic testing?

To generate test inputs that cover all equivalence partitions.

To verify expected outputs when the oracle is unclear by checking relationships between outputs of related test cases.

To prioritize test cases based on the likelihood of failure.

To reduce the number of test cases needed by combining multiple inputs into one test.
