Ensure software reliability and security with API testing in the USA.

API testing is an essential part of API development and is known to be one of the most difficult types of software testing. When conducting REST API testing, it is not enough to know that clicking a button will send a request to the server. It is important to be aware of the components of a REST request, how to create, formulate, and send requests without relying on the UI, and also to understand what to expect as a response when sending a test request to make sure the API is operating properly.

On top of that, there are several points that should be taken into account: the accuracy of data, schema validation, data type, validations, order and completeness, HTTP status codes, authorization checks, and error codes API returns.

We worked with QAwerk on a new mobile app. They develop test plans, continue to do regression testing, and are also developing automated test coverage. I was really impressed with the depth and thoughtfulness of all the work, and even giving feedback on the app functionality itself. QAwerk has been very responsive to requests—I'm not sure when they ever sleep! The team is very clear and organized with managing the overall project and communication. Highly recommend!

I feel like our QA was so bad, but we definitely improved it with QAwerk, and looking forward to some new improvement with you.
