This document discusses the benefits of test-driven development (TDD) and unit testing over traditional approaches to coding without tests. It notes that coding without tests can lead to bugs that are difficult to fix and applications that are hard to update. TDD involves writing tests before production code to specify functionality, then writing just enough code to pass each test. This approach prevents bugs and ensures code quality and performance while improving maintainability. The key principle of TDD outlined is to not write any production code without a failing test first.

- 1. Test Driven Development Unit Testing
- 2. It was satisfying to write code without TESTS Run it in browser or va_dump() it Write code Something went wrong ? Yes No Next >>
- 3. FLASH IN THE PAN ● Couldn’t Agile. ● Fixing one bug will result alot more. ● Unoptimizabel. ● Couple line of code can break the whole application ( Break Code ). ● Can’t updatable. ● Increase Costs and Times.
- 4. SOLUTION TDD Test Driven Development Unit Testing 1. You are not allowed to write any production code without first writing a test that fails because the production code does not exist. 1. You are not allowed to write more of a test than is sufficient to fail; including failure of compilation. 1. You are not allowed to write more production code than is sufficient to pass the currently failing test. ● Prevents long hours of debugging and rework ● Ensure our performance ● 100% Coverage feels so good ● Better maintainability
