Study Notes
TDD Cycle and Testability
- The main purpose of short TDD cycles is to ensure rapid feedback and continuous improvement in code quality.
Designing for Testability
- Developers should design implementations with testability in mind to ensure that the code can be easily tested and validated.
Unit Testing
- The first step in unit testing is to write a unit test, which is a small, self-contained piece of code that verifies the behavior of a specific unit of code.
Larger Tests
- Larger tests, such as integration tests and system tests, focus on verifying how different units of code work together to achieve a larger goal.
Automated Testing Tools
- The purpose of applying automated, intelligent testing tools after engineering tests is to increase testing efficiency and reduce the time and cost associated with manual testing.
Effective Testing
- Testing is effective when it finds defects and ensures that the code meets the required standards and specifications.
Exhaustive Testing
- Exhaustive testing is impossible because it would require testing every possible input and scenario, which is impractical and often impossible.
Stopping Criteria
- The principle for knowing when to stop testing is when the cost of finding the next defect is greater than the benefit of fixing it.
Cost of Bugs
- The cost of fixing bugs in production is significantly higher than preventing them in the first place, which emphasizes the importance of testing and quality assurance.
Systematic Testing
- The aim of being systematic in testing is to ensure that testing is thorough, consistent, and repeatable, which helps to increase confidence in the quality of the code.
