Greeting Salutations
Example Conversation
Insider
Happy contract testing!
Outsider
Huh? What do you mean by that?
Insider
It's a way we greet each other wishing that our API contracts are always honored correctly.
Outsider
Oh cool, that sounds like a fun tradition to keep motivation up!
Cultural Context
This greeting highlights the community's focus on contract testing and adds camaraderie around a shared responsibility to maintain API integrity.
Inside Jokes
"Did you try turning it off and turning the API back on?"
A tongue-in-cheek reference to the common IT advice 'try turning it off and on again,' humorously applied here to flaky APIs that seem fixed by redeploying or restarting services.
"Swagger is not just a feeling"
A pun that plays on the Swagger tool (OpenAPI specs) used in API definitions and the common English word 'swagger,' emphasizing the importance of proper API documentation.
Facts & Sayings
„Shift left!“
A call to integrate API testing earlier in the software development lifecycle to catch issues sooner and speed up feedback.
„Mock it till you make it“
Refers to creating mock servers or endpoints to simulate API responses during testing before the real API is available or stable.
„Contract is king“
Emphasizes the importance of API contract testing to ensure that different services communicate correctly according to their agreed specifications.
„Flaky endpoints are the bane of my existence“
An expression of frustration about intermittent API endpoints that cause inconsistent test results, a common headache in API testing.
„Collections speak louder than words“
Highlights the significance of well-organized test collections (e.g., Postman Collections) that encapsulate reusable test scripts and configurations.
Unwritten Rules
Always version your API test collections.
Helps track changes, avoid breaking tests suddenly, and communicate updates clearly across teams.
Don’t trust test responses blindly; always validate against the API contract.
Ensures that tests detect mismatches early and maintain consistency with API specifications.
Keep test scripts idempotent and independent whenever possible.
Prevents flaky test suites and simplifies debugging by ensuring tests don't depend on prior state or side effects.
Share reusable test scripts and snippets openly within the team or community.
Encourages collaboration and speeds up quality improvements by reducing duplicated effort.

First Steps & Resources
Get-Started Steps
Time to basics: 1-2 weeks
1
Learn API Fundamentals
2-4 hoursBasic
Summary: Study what APIs are, how they work, and common protocols like REST and HTTP methods.
Details: Before diving into API testing, it's essential to understand what APIs are, how they facilitate communication between software components, and the protocols they use (like REST, SOAP, and GraphQL). Focus on learning about endpoints, requests, responses, status codes, and authentication basics. Beginners often skip this and struggle to interpret test results or debug issues. Use diagrams and interactive tutorials to visualize API flows. This foundational knowledge is crucial for understanding what you are testing and why. Progress can be evaluated by being able to explain how a simple API call works and identifying the components of a request and response.
2
Explore API Testing Tools
1-2 hoursBasic
Summary: Install and experiment with popular API testing tools to understand their interfaces and capabilities.
Details: Hands-on familiarity with API testing tools is a core skill. Start by downloading and installing a widely-used tool (such as open-source or free versions). Explore the interface, create a simple request, and observe how to send and receive data. Beginners may feel overwhelmed by tool features; focus on basic operations like sending GET/POST requests and viewing responses. Try out built-in features like history, environment variables, and basic scripting. This step is important because tool proficiency is expected in the community. Evaluate your progress by successfully sending requests and interpreting responses using the tool.
3
Practice Testing Public APIs
2-3 hoursIntermediate
Summary: Find open/public APIs and perform basic tests: send requests, check responses, and handle errors.
Details: Apply your knowledge by interacting with real-world public APIs. Choose a simple, well-documented API (such as a weather or joke API). Practice sending different types of requests (GET, POST), examine the responses, and intentionally trigger errors (e.g., invalid parameters) to see how the API reacts. Beginners often overlook error handling—make sure to test both expected and unexpected scenarios. Document your findings and compare them to the API documentation. This step builds practical skills and confidence. Progress is measured by your ability to successfully interact with an API and interpret both successful and error responses.

4
Join API Testing Communities
1-2 hoursBasic
Summary: Engage in forums or chat groups to ask questions, share experiences, and learn from practitioners.
Details: Community engagement accelerates learning and exposes you to real-world challenges and solutions. Join online forums, chat groups, or social media spaces dedicated to API testing. Introduce yourself, read through beginner threads, and ask thoughtful questions. Participate in discussions about tools, best practices, and troubleshooting. Beginners may feel intimidated, but most communities are welcoming to newcomers who show genuine interest. This step is vital for staying updated and building a support network. Evaluate progress by your comfort in asking questions and contributing to discussions.
5
Design and Automate Simple Tests
2-4 hoursIntermediate
Summary: Write and automate basic test cases for a sample API, including assertions for status codes and data.
Details: Move beyond manual testing by designing and automating simple test cases. Use your chosen tool’s automation features or basic scripting to create tests that check for correct status codes, response times, and expected data in the response body. Start with straightforward scenarios, then add negative tests (e.g., invalid input). Beginners often struggle with writing clear assertions—review examples and templates. Automation is a key skill in this bubble, and even basic scripts are highly valued. Progress is shown by having a small suite of automated tests that run and report results reliably.
