Request Tester is a Chrome add-on developed by Chesical. It is a powerful tool for testing HTTP requests using the JavaScript Fetch API.

With Request Tester, you can easily generate and customize URLs by editing and assembling the different elements. It allows you to set various options available in the Fetch API through a user-friendly interface. This makes it convenient to modify and experiment with different request configurations.

One of the key features of Request Tester is the ability to save and recall test conditions. This allows you to quickly switch between different test scenarios without having to manually reconfigure each time.

Furthermore, Request Tester provides a comprehensive display of the response. You can view the success or failure of the request, the response time, and the status. Additionally, the results can be displayed in three different formats: text, HTML, or JSON.

For developers, Request Tester also offers the functionality to generate JavaScript code using the Fetch API. This code can be used to perform the same communication as the test conditions specified in the tool.

With its intuitive interface and powerful features, Request Tester is a valuable tool for developers and testers who need to perform HTTP request testing using the Fetch API.
