This quiz covers unit testing, integration testing, end-to-end testing, mocking, fixtures, code coverage, and more. Test your knowledge and understanding of these essential concepts in software testing. Good luck! Answer key and explanations20 questions The quiz above draws 20 questions at random from these 30, so a second attempt will not be the same run. Everything in the pool is listed here. 1. What is unit testing? AnswerThe practice of verifying individual functions or methods in complete isolation 2. What is integration testing? AnswerThe verification of interactions between multiple components or external services 3. What is end-to-end (E2E) testing? AnswerThe simulation of complete user workflows from the frontend through to the backend 4. What is the test pyramid? AnswerA strategy favoring many unit tests, fewer integration tests, and minimal E2E tests 5. What is a mock? AnswerA replacement for a dependency that allows for controlling and inspecting behavior 6. What is a stub? AnswerA simplified object that returns fixed, predetermined data for specific calls 7. What is a spy? AnswerA wrapper around a function that records details about how it was called 8. What is a fixture? AnswerA baseline set of data or state used consistently across multiple test cases 9. What is code coverage? AnswerA metric indicating the percentage of source code executed during a test suite 10. What is Cypress? AnswerA modern, browser-based framework designed for end-to-end testing 11. What is test isolation? AnswerEnsuring that the outcome of one test does not affect the outcome of another 12. What is a flaky test? AnswerA test that provides inconsistent results without any changes to the code 13. What is Test-Driven Development (TDD)? AnswerA process where you write a failing test before writing the actual implementation 14. What is Behavior-Driven Development (BDD)? AnswerA methodology using human-readable descriptions to define how an application should act 15. What is snapshot testing? AnswerA technique that compares the current output of a component to a previously stored version 16. What is the AAA (Arrange-Act-Assert) pattern? AnswerA structural pattern that divides a test into three clear, sequential phases 17. What is parameterized testing? AnswerA method for executing the same test logic multiple times using different input data 18. What is regression testing? AnswerRe-running existing tests to confirm that new changes have not introduced any new bugs 19. What is smoke testing? AnswerA preliminary set of tests that verify the most critical functions of an application 20. What is performance/load testing? AnswerA strategy to evaluate how a system performs under a high volume of concurrent users 21. What is security testing? AnswerThe practice of identifying vulnerabilities and threats in application code or infrastructure 22. What is contract testing? AnswerA technique to ensure that a provider and a consumer of an API agree on the data format 23. What is mutation testing? AnswerAn advanced method that modifies the source code to check if the test suite fails 24. What is property-based testing? AnswerA strategy where a test generates random data to verify that certain logic properties always hold 25. What is accessibility testing? AnswerThe practice of ensuring that software is usable by people with various disabilities 26. What is the test data builder pattern? AnswerA design pattern that uses a fluent interface to construct complex objects for testing 27. What is test isolation and why is it important? AnswerA requirement that tests remain independent to prevent side effects and shared state 28. What is continuous testing in CI/CD? AnswerThe automated execution of software tests as part of the software delivery pipeline 29. What is canary testing and canary deployment? AnswerThe process of releasing a new version of code to a small group of users to monitor performance 30. What is chaos engineering and chaos testing? AnswerThe discipline of experimenting on a system to ensure its ability to withstand turbulent conditions ## Tags [#Testing](/quizzes/tags/testing)[#Quality](/quizzes/tags/quality)[#DevOps](/quizzes/tags/devops) ## Share [Facebook](https://facebook.com/sharer/sharer.php?u=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Ftesting-strategies-quiz "Share on Facebook")[Twitter](https://twitter.com/intent/tweet/?text=Testing%20Strategies%3A%20Unit%2C%20Integration%2C%20E2E&url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Ftesting-strategies-quiz "Share on Twitter")[LinkedIn](https://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Ftesting-strategies-quiz&title=Testing%20Strategies%3A%20Unit%2C%20Integration%2C%20E2E&summary=Master%20testing%3A%20unit%20testing%2C%20integration%20testing%2C%20end-to-end%20testing%2C%20mocking%2C%20fixtures%2C%20coverage%20goals%2C%20and%20CI%2FCD%20integration.&source=https://mkabumattar.com "Share on LinkedIn")[WhatsApp](https://wa.me/?text=Testing%20Strategies%3A%20Unit%2C%20Integration%2C%20E2E%20https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Ftesting-strategies-quiz "Share on WhatsApp")[Telegram](https://t.me/share/url?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Ftesting-strategies-quiz&text=Testing%20Strategies%3A%20Unit%2C%20Integration%2C%20E2E "Share on Telegram")[Reddit](https://www.reddit.com/submit?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Ftesting-strategies-quiz&title=Testing%20Strategies%3A%20Unit%2C%20Integration%2C%20E2E "Share on Reddit")[Hacker News](http://news.ycombinator.com/submitlink?u=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Ftesting-strategies-quiz&t=Testing%20Strategies%3A%20Unit%2C%20Integration%2C%20E2E "Share on Hacker News")[Pinterest](https://pinterest.com/pin/create/button/?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Ftesting-strategies-quiz&media=&description=Master%20testing%3A%20unit%20testing%2C%20integration%20testing%2C%20end-to-end%20testing%2C%20mocking%2C%20fixtures%2C%20coverage%20goals%2C%20and%20CI%2FCD%20integration.
