This document discusses the benefits of unit testing by describing common problems that unit tests can help address, such as bugs found late in the development process, services that do not work as expected when integrated, difficulties with code changes requested by clients, and delays in schedules due to unexpected bugs. It defines what a unit test is and explains that while unit tests take more time initially, they help developers be confident in their code, welcome changes, and achieve good test coverage during each sprint.
![What is Unit Test?
• Verifies an atomic piece of code
• Tests one specific behavior
• Each Test is autonomous
[TestMethod] public void
CheckPassword_ValidUser_ReturnTrue() { bool result =
CheckPassword(“user”, “pass”); Assert.IsTrue(result); }](https://image.slidesharecdn.com/unittesting-140327052721-phpapp01/85/Benefits-of-Unit-Testing-11-320.jpg)
Benefits of Unit Testing
- 1. Benefits of Unit Testing By Barkan Saeed
- 2. • • One bug left before release • Done! • Send version to QA, • QA: It doesn’t work! Problem #1
- 3. Programme r
- 4. Problem #2 - Developer 1 writes web-services on day 1 and 2 - Developer 2 is scheduled to write an app to consume those services on day 3 and day 4 - Problem : Services don’t work as expected How will this affect schedule?
- 5. Client
- 6. Problem # 3 • We don’t like changes • But business requirements change thats why we work agile. • Developer problem: Changes are not good because they break code
- 7. Developer when seeing Change Request
- 8. Problem # 4
- 9. Delays in Schedule • Unexpected Bugs • Client frustration • Delays in schedules
- 10. Where does it hurt?
- 11. What is Unit Test? • Verifies an atomic piece of code • Tests one specific behavior • Each Test is autonomous [TestMethod] public void CheckPassword_ValidUser_ReturnTrue() { bool result = CheckPassword(“user”, “pass”); Assert.IsTrue(result); }
- 12. Does it take more time? Yes!
- 13. How can these unit tests help us?
- 14. Be Confident about our code.
- 15. Welcome Change
- 16. Automated tests are the only way to achieve a good test coverage in each sprint
- 17. Future - NewBie’s - Should understand XUnit - Start with Regression areas first
