Coding Session: TDD 101
summary
A live coding session demonstrates TDD using Jest in watch mode to implement a DOM-manipulating function that generates numbers 1–100 and replaces multiples of 3 with “физ”, multiples of 5 with “баз”, and multiples of both with “из баз”. The workflow shows step-by-step minimal implementations to satisfy each test, followed by refactoring of tests and code, with fast short test–code cycles and explicit examples of conflicting requirements.
