I want to create a tool that will accept the “OpenAPI v3 definition” document as input. Based on that, it will generate basic test cases to validate/check the API behaviour using Java/Spring Boot. Can someone please help with that or give me some suggestions on how I can achieve this? I am new to Spring Boot.

You can use STT like any other Node.js module in a Node.js project, completely on its own.The test files for an example of how to run it standalone. Furthermore, the API doesn't have to be implemented in Node.js for a STT generated test to target it with an HTTP request. You have to use Node.js to utilize this module's functionality, but as long as you point the tests at a running server (localhost:1337, my.api.test.net) the backend implementation doesn't matter. The caveat here is that this module was designed to run with mocha which is a Node.js test runner/framework. So the tests have to be in a Node.js project, but the server implementation doesn't.

That being said, it does generate Node.js code, not Java code, if that is what you were looking for. Please follow up if I can be answer anything more.

One way to generate test cases from OpenAPI v3 description is by using an automated testing framework like JUnit or TestNG. These frameworks provide an easy way to create and run tests using Java and Spring Boot.

Another way to generate test cases is by using a tool like Swagger Codegen. Swagger Codegen is an open-source tool that can generate code from your OpenAPI v3 definition. Once generated, you can use the generated code to create a set of tests that will validate or check the API behaviour.

Finally, you can also use a framework like REST Assured to generate test cases from your OpenAPI v3 definition. REST Assured is a Java-based framework that allows you to easily test RESTful web services. It provides an easy way to create and run tests using Java and Spring Boot.

Autogenerating test cases from an OpenAPI v3 description using Spring Boot/Java can be done by leveraging the OpenAPI Generator library. It allows you to generate client libraries, server stubs, and documentation for a variety of different languages, including Java/Spring.

To create a tool that can generate basic test cases for an API using OpenAPI v3 definition and Spring Boot, you can follow these steps:


Parse the OpenAPI v3 definition document using a library such as Swagger Parser or OpenAPI Parser to extract the API endpoints, request and response schemas, and other relevant information.


Use a testing framework such as JUnit or TestNG to write tests for each endpoint. You can generate the test cases dynamically based on the information extracted from the OpenAPI document.


Use a library such as RestAssured to make HTTP requests to the API endpoints and validate the responses against the expected schemas.


Generate code for the tests using a code generation tool such as OpenAPI Generator, which can generate Java code for the API client and the test cases.


Integrate the generated tests into your Spring Boot application and run them as part of your continuous integration (CI) process.


Overall, creating a tool to generate tests for an API using OpenAPI v3 and Spring Boot can be a complex task, but it can greatly improve the quality and reliability of your API. It may be helpful to start with a small subset of the API endpoints and gradually expand the scope as you gain more experience.

You can use tools like Swagger Codegen or OpenAPI Generator to generate test cases from OpenAPI v3 description in Spring Boot/Java. #OpenAPI #SpringBoot #testautomation

Creating a tool to autogenerate test cases from an OpenAPI v3 description using Spring Boot/Java is possible, but it will require some work. You can start by familiarizing yourself with the OpenAPI v3 specification and the Spring Boot framework. You will also need to understand the basics of Java programming and the different types of testing that can be done with an API. Once you have a good understanding of these topics, you can begin to develop your tool. You may also want to consider using an existing tool or library that can help you with this task.
