In a regression-averse test approach, what should be the focus of test automation?
Answer : D
Regression-Averse Test Approach:
This approach minimizes risks by ensuring tests remain relevant and effective over time. The key focus is maintaining and enhancing the regression suite to reflect changes in the software.
Continuous Improvement of Tests:
Keeping tests updated ensures the test suite is reliable and maintains high coverage. This involves adding tests for new features, removing obsolete tests, and refining existing ones.
Conclusion:
Option D is correct because it aligns with the goals of regression-averse approaches.
You have been asked to supply the data file for a data-driven test automation script that will be used to test the following story:
As a customer, I want to be told how many items I need to purchase, so I can receive free shipping.
You have been told the automation will verify whether or not the free shipping message is displayed. Which of the following columns should appear in your data file to support the automated testing of this story?
Answer : B
Data-Driven Testing:
Data-driven testing focuses on varying inputs and verifying expected outputs. For this story, the key input is the quantity of items purchased, and the output is whether free shipping applies.
Relevant Columns:
Item ID: Identifies the product.
Quantity Purchased: Determines whether the free shipping threshold is met.
Free Shipping (y/n): Validates if the message is correctly displayed.
Conclusion:
Option B is correct as it includes the minimum required data to test the user story effectively.
You are developing a test automation suite for an agile project and want to include as much coverage as possible. Unfortunately, one of the critical web services (e-commerce checkout) is not scheduled for completion until the later iterations. Which of the following would be a good option to allow you to progress with your end-to-end test automation without creating too much extra work?
Answer : C
Service Virtualization in Agile:
Virtualized services are ideal for simulating unavailable components, enabling comprehensive testing without waiting for the actual service to be developed.
Minimizing Extra Work:
Using a service virtualization tool reduces the need for manual creation and maintenance of stubs or other temporary solutions.
Analysis of Options:
A is impractical, as testers should not develop production services.
B is less efficient than service virtualization and requires ongoing setup/teardown.
C provides an efficient and reusable solution.
D risks misalignment with the new system.
Conclusion:
Option C is the best approach for agile test automation progress.
You are testing a payment processing application that calls an external service at a bank to process monetary transactions. The bank charges per transaction for the use of their service. You are creating an automation suite that will be used as part of continuous testing. How could service virtualization benefit the project if a virtualized service is created that will act in the same way as the bank application?
Answer : B
Purpose of Service Virtualization:
Service virtualization allows simulation of external services during testing, enabling cost-effective and efficient testing without relying on the live service.
Cost Reduction:
The bank charges per transaction, and using the actual service during continuous testing could incur significant fees. Virtualized services eliminate these fees, reducing costs.
Analysis of Options:
A: While a virtualized service may improve speed, the primary benefit here is cost savings.
B: Correct, as eliminating transaction fees directly addresses the problem.
C: Virtualization doesn't inherently improve security for automation code.
D: Virtualized services don't necessarily reduce data management needs.
Conclusion:
Option B is correct as it highlights the key advantage of cost savings.
You are working for an organization that has implemented CI and is struggling to get the automated tests to run on each build because of time limitation. On average, there are three ad hoc builds per day, one scheduled build overnight, one scheduled build on Friday nights, and one build that is conducted on the Thursday night before the end of the sprint on the second Friday. There are four sets of tests: high priority, medium priority, low priority, and non-functional. The non-functional tests must be run in the integrated stage environment, whereas the other tests can be run in any of the test environments.
In addition to just the execution time of the tests, it has also been noted that reviewing the results of the tests takes about two hours per set of tests.
Given this information, which of the following is the most efficient and effective approach to test automation execution?
Answer : D
Testing Constraints in CI:
The time limitations for test execution and results review necessitate prioritization of tests based on criticality and frequency of code changes.
Efficient Allocation:
High-priority tests should run on each build to catch critical issues early.
Medium-priority tests can be run nightly to balance coverage and time constraints.
Low-priority tests are less critical and can run weekly.
Non-functional tests require the integrated stage environment and should run at a predefined time (e.g., Thursday night before sprint end).
Analysis of Options:
A: Running all tests every night is impractical due to time constraints.
B: Medium-priority tests should be run more frequently than at the end of the sprint.
C: Running all tests on every build is unrealistic given the time and resource limitations.
D: Correct, as it ensures efficient prioritization and scheduling of test sets.
Conclusion:
Option D provides the most efficient and effective test execution strategy.
