𝟱 𝗔𝗣𝗜 𝘁𝗲𝘀𝘁𝗶𝗻𝗴 𝗯𝗲𝘀𝘁 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗲𝘀 👇 How do you test your APIs properly? API testing is the process of confirming that an API is working as expected. Developers can run API tests manually, or they can automate them with an API testing tool. There are many ways to test an API, and each one serves a unique purpose: 1. Contract testing 2. Unit testing 3. End-to-end testing 4. Load testing Here are some API testing best practices: 1. 𝗖𝗿𝗲𝗮𝘁𝗲 𝗮 𝗱𝗲𝗱𝗶𝗰𝗮𝘁𝗲𝗱 𝘁𝗲𝘀𝘁𝗶𝗻𝗴 𝗲𝗻𝘃𝗶𝗿𝗼𝗻𝗺𝗲𝗻𝘁 Teams should perform API testing in a dedicated environment before pushing changes to production. This prevents issues and avoids user downtime. The testing environment should closely mirror production but use mock data that can be safely manipulated and replaced. 2. 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗲 𝘆𝗼𝘂𝗿 𝗔𝗣𝗜 𝘁𝗲𝘀𝘁𝘀 Manual API testing helps debug specific issues, but test automation ensures consistent coverage and reduces human error. Teams can use various tools to create test suites and schedule executions at specific times, frequencies, or in CI/CD pipelines after every commit or push. 3. 𝗥𝘂𝗻 𝘁𝗲𝘀𝘁𝘀 𝘁𝗵𝗿𝗼𝘂𝗴𝗵𝗼𝘂𝘁 𝘁𝗵𝗲 𝗔𝗣𝗜 𝗹𝗶𝗳𝗲𝗰𝘆𝗰𝗹𝗲 Traditional API testing after development can miss issues until they are hard to fix. Teams should run API tests at every stage of the lifecycle. Different tests are relevant at different stages; contract tests are written at design and used for all iterations, while unit tests are for development and CI/CD. Testing early and often helps identify and fix issues quickly, ensuring high-quality APIs. 4. 𝗪𝗿𝗶𝘁𝗲 𝗿𝗲𝘂𝘀𝗮𝗯𝗹𝗲 𝘀𝘂𝗯𝘁𝗲𝘀𝘁𝘀 Every API endpoint requires custom tests, but some rules apply universally, like response time limits or JSON formatting. Instead of repeating this logic, teams can create reusable subtests. This reduces human error and ensures consistent testing for each endpoint. 5. 𝗞𝗲𝗲𝗽 𝘆𝗼𝘂𝗿 𝘁𝗲𝘀𝘁𝘀 𝗼𝗿𝗴𝗮𝗻𝗶𝘇𝗲𝗱 Teams should use a logical and scalable framework for their API test suite as the API evolves. Tag tests for easy batch execution, create distinct test suites for each API resource and keep unit tests separate from end-to-end tests. This organization prevents duplicate logic, removes outdated tests, and helps new engineers onboard quickly. How do you test your APIs?
