We spend half of our coding time reading, writing or fixing tests. But who likes that? To quickly fix this chore, we often copy-cat older tests or write new ones without paying much attention to their quality. This deep-dive walks you through a variety of practical testing techniques and tricks you must have in your toolbox to write expressive tests with a higher signal/noise ratio. In the agenda: test structure & naming, mutation testing (vs AI-gen tests), ObjectMother, why never to use assertEquals, nested fixtures, parameterized use/abuse, Gherkin, plus a few surprises. All this through an entertaining and interactive session that puts the joy back into testing.
An entertaining tour of the most common mistakes in designing an API (with examples): Domain Leakage, Sensitive Data Exposure, Performance issues, CQRS, PUT overload, and breaking changes. Collected with love from over 150 companies.
