Using OpenAPI Codegen for TypeScript to Generate Client Code and Automate Testing
This basic guide will walk you through using OpenAPI Codegen to generate TypeScript client code from an OpenAPI specification, creating a test client, and automating test cases with Jest. We will also show you how to set up essential scripts in your `package.json` file to streamline the development and testing process. As our example, we'll use the Petstore API specification.
