If you’re planning on automating your API testing efforts, you’ll need an API test automation tool. While there are many choices, a good tool should cover the end-to-end flow of a given service. Data-driven testing allows you to use dynamic data sources to generate test results. Parallel execution of tests can minimize the test execution time. Additionally, built-in test reports include HTTP requests and response logs, which can help you debug any test automation failures. Some tools also include validation of the schema of all JSON elements.
When creating API tests, remember to create robust scenarios. Each scenario should cover every possible scenario that could happen. Work with your business analyst to create realistic scenarios and link them to your API environment with an external data source, such as an excel spreadsheet. This way, you can test for all possible failures, including those related to data integrity and confidentiality. Then, alter test cases as needed to improve service quality. In addition, make sure to prioritize and document each test case thoroughly before using an API test automation tool.
Once you’ve defined the API test scenarios, you’ll need a tool to execute them. Some tools are better than others, but they all have their own benefits and drawbacks. One tool, Postman, is a great example of an API testing tool. It can be used on Mac and Windows, and it’s free. This tool even supports Swagger and RAML, enabling you to test different versions of a service.
Another great tool for testing APIs is Zaptest, which is a CLI (command line) API test automation. This program helps you automate manual API testing with a minimal amount of code. It allows you to write end-to-end test cases, and it also supports SOAP and REST requests. It also supports CI/CD integrations. It has a user-friendly interface, so you won’t need to learn programming to run tests.
Karate, a free, open-source API test automation tool, is also a good choice. It combines API test automation with mocks, performance testing, and UI automation. Its syntax, based on the cucumber library, makes it easy to use, even for people without extensive experience in programming. Karate also supports multi-threaded parallel execution and reusing Payload-data. It is the perfect API test automation tool for teams with limited programming knowledge.
APIs are constantly changing, which means that your API testing tool should be flexible enough to fit into your environment. Many API test automation tools support native integration with various environments, including CI/CD. With this tool, you can run tests through the command line, generate realistic load scenarios, and reuse functional tests. You can also use features such as job queuing and reusing functional tests to generate realistic load scenarios. You can also use other tools like Slack or GitHub to integrate it with API testing.
Apigee is another API test automation tool. This tool allows you to run tests across browsers and even create proxies based on the Open API Specification. The tool has four packages that you can choose from. You can get a free trial of both of them. There are also multiple features in the trial versions. If you’re not sure whether it’s the best fit for your API testing needs, check out the free version of Apigee to get a feel for how the tool works.
