Why you must use TDD now!
#1about 3 minutes
The problem with traditional development cycles
Traditional development, where tests are written after implementation, often leads to bugs slipping through QA and into production.
#2about 3 minutes
Understanding the Red-Green-Refactor TDD cycle
TDD inverts the traditional process by first writing a failing test (Red), then writing just enough code to make it pass (Green), and finally cleaning up the code (Refactor).
#3about 8 minutes
Demo: Writing the first failing test for a health endpoint
The demo begins by creating a test for a server health endpoint, which fails because the endpoint and server configuration do not exist yet.
#4about 9 minutes
Demo: Implementing an addition feature using TDD
A calculator's 'add' endpoint is built by writing a failing test, implementing minimal code to pass, and then refactoring the test with multiple cases to ensure correct logic.
#5about 5 minutes
Evaluating the pros and cons of adopting TDD
TDD leads to more testable solutions and cleaner architecture but requires discipline and team buy-in to overcome the initial temptation to write implementation code first.
