Thunder Client is the first in the industry to launch GUI-based assertions.
  • We need to write a lot of boilerplate code in Postman and other clients to do basic testing using scripting (like status code equals 200). So we implemented GUI-based tests, where you can select a couple of dropdowns to do most standard tests easily, without any scripting knowledge.
  • Tests can be done for strings, numbers, count, and type checking.
  • Json schema validation.
  • Re-arrange tests order using drag & drop.
