Kotlin API testing with Ktor client validates REST endpoints.

Introduction to Ktor Client for API Testing

Kotlin's Ktor client is a powerful tool for interacting with RESTful APIs. It allows developers to perform HTTP requests with ease, making it an excellent choice for API testing. In this section, we'll explore how to set up and use Ktor client to validate REST endpoints.

Setting Up Ktor Client

To use the Ktor client, you need to add the necessary dependencies to your Kotlin project. Ensure your build.gradle.kts is updated as follows:

Making a Simple GET Request

Once the Ktor client is set up, you can start making HTTP requests. Below is an example of a simple GET request to a REST endpoint:

Testing POST Requests

Testing POST requests is straightforward with Ktor. You can send data to an endpoint using the post method:

Handling Responses and Errors

Handling responses and errors effectively is crucial for robust API testing. Ktor provides mechanisms to deal with HTTP status codes and exceptions:

Conclusion

In this guide, we've covered the basics of using the Ktor client for API testing in Kotlin. You learned how to set up the client, perform GET and POST requests, and handle responses. With these tools, you can effectively validate REST endpoints in your applications.
