Quick Recap:
The "Zero Complexity API Testing" blog series, spanning three parts, delves into the crucial role of API testing, explores how AI is breaking down barriers, and unlocks new possibilities in the future of API testing.
Many questions about API testing automation, such as "What is the API testing process?" or "Can APIs be QA tested?" are easily answered online. This blog series goes deeper, using real-world scenarios to uncover the nuances of API testing.
In Part I of the series, we discussed the critical importance of API testing and the challenges UI testers face when transitioning to API testing. We followed Emily, a lead tester at a fast-growing e-commerce company, as she encountered an API glitch that left customers frustrated. Despite understanding the API testing process, Emily chose to make it optional, leading to a chaotic situation.
In Part II (this blog), we’ll explore how Emily's team could have prevented the issue using Qyrus’ codeless API testing capabilities. We’ll also see how Qyrus simplifies test creation and execution, making it accessible even to non-technical testers.
This blog also covers how AI is integrated into API testing and how Qyrus supports codeless assertions, API spec imports, data-driven testing, API chaining, and AI-powered assertions. It even highlights Qyrus’ ability to perform performance testing under massive loads.
Ultimately, the blog emphasizes how Qyrus equips teams to effectively test their APIs, ensuring functionality, reliability, and performance.
Let’s see how Emily’s team could have overcome their challenges with Qyrus.
Codeless API Testing
One of Qyrus’ standout features is codeless API testing, which empowered Emily’s team to build and run tests without writing any code. The intuitive interface enabled even non-technical testers to get involved, democratizing API testing for her entire team.
With Qyrus, creating an API test is as easy as selecting the endpoint, defining request parameters, and specifying the expected response. This simplicity allowed Emily’s team to create comprehensive tests without getting caught up in technical details.
Codeless Assertions
Adding assertions for headers, body content, JSON Path, and schema validation was as simple as clicking a few buttons. This meant that Emily’s team could ensure API responses met expected criteria without needing complex scripts. They easily verified that APIs returned the right data and performed as expected, improving coverage and reliability.
Qyrus offers a user-friendly interface to define these assertions, from validating response headers and bodies to checking JSON Path expressions and schema structures. This support extended to complex scenarios like verifying nested JSONs and ensuring specific keys and values were present.
Importing API Specifications
Qyrus allows teams to import API specifications using OpenAPI/Swagger, Postman Collections, or manual input. This flexibility meant Emily’s team could quickly leverage existing API documentation, importing specs and beginning tests without delay, saving both time and effort.
By importing these specs, Qyrus automatically generates test cases for each API endpoint, complete with sample requests and expected responses. This automation speeds up test creation and ensures comprehensive endpoint coverage.
Data-Driven Testing
Qyrus enables data-driven API testing, allowing the use of external data sources to drive test cases. This feature helped Emily’s team test their APIs across a range of scenarios, improving test coverage by simulating different conditions and inputs.
Testers could define data sets in CSV or JSON format and link them to API test cases, running varied tests with multiple inputs like different user profiles, transactions, and order details.
API Chaining and Data Flow
Qyrus allows for API chaining, where data from one API is passed to another. For instance, a JSON Path value from one API could serve as a header for the next, simulating real-world API interactions. This made it easier for Emily’s team to test complex workflows and interactions, ensuring seamless system functionality.
API chaining in Qyrus facilitates end-to-end testing by creating scenarios that mirror real user experiences, such as creating accounts, adding items to carts, and processing payments in one cohesive test.
AI and Performance: A Competitive Edge with Qyrus
AI-Assisted Assertions
A key feature of Qyrus is its AI-assisted assertions. The AI analyzes API responses and suggests assertions, reducing the time needed for test creation and ensuring thorough coverage. For Emily’s team, this was a game-changer, allowing them to focus on critical tasks while the AI handled repetitive work.
The Qyrus AI engine uses machine learning to identify key response data, suggesting relevant assertions based on typical patterns and expected values. This automation makes it easier to create comprehensive test cases, minimizing the risk of missing critical validations.
Performance Testing at Scale
With Qyrus, Emily’s team could run performance tests on their APIs without any modifications. Qyrus leverages cloud-based infrastructure to run high-load performance tests, ensuring APIs can handle significant traffic. This capability allowed Emily’s team to validate that their APIs were not only functional but scalable under heavy loads.
Qyrus simulates thousands of concurrent users and large volumes of API requests, allowing testers to monitor performance metrics such as response times and error rates under different loads. Detailed reports highlight performance bottlenecks, helping teams make informed decisions.
Support for Multiple API Types
Qyrus supports testing across different API types, including GraphQL, REST, and SOAP, with Kafka integration on the way. This flexibility meant Emily’s team could use Qyrus across multiple projects and technology stacks, ensuring consistent testing regardless of the API type.
The platform’s multi-protocol support simplifies the process for testers, providing a unified interface and feature set, regardless of the underlying API technology.
Qyrus’ API Discovery Chrome Plugin
The Qyrus API Discovery Chrome plugin was a game-changer for Emily’s team. It allowed them to extract relevant APIs directly from their web application, generate assertions, and export them as test suites in Qyrus, transforming manual web testing into a source for automated API tests. This significantly enhanced test coverage and efficiency.
By capturing API calls during manual testing sessions, the Chrome plugin helps testers seamlessly transition from manual to automated testing, improving overall efficiency.
Sneak Peek into Part III: The Future of API Testing
Now that Emily’s team has transformed their API testing with Qyrus, they can focus on improving the overall quality of their e-commerce platform.
With AI-powered assertions, enhanced test coverage, and scalable performance testing, Qyrus has opened new possibilities for Emily’s team, helping them achieve more in less time.
Stay tuned for Part III, where we explore the future of API testing and unlock new advancements in this space. In the meantime, try the Qyrus Freemium version to experience fast, insightful API automation testing firsthand!
