Increasing the efficiency in bug detection and making API calls
The final result was that there was more than 80% coverage in functional testing at Angler Technologies… The API tests can be run and completed in a matter of seconds. The team can run API calls as many times as possible with multiple inputs to measure the response time and performance issues. Their interoperability and integration issues have been reduced as well.
Optimizing regression and API testing
With the Katalon quality management platform, Johnson and team are able to test system functionality across critical front-end journeys within Guidewire, and use API testing to ensure third-party quote aggregators are operating as planned.

“Sufficient tool for REST API testing. Fortunately, due to Katalon Studio's intuitive setup, I don't need scripting knowledge or experience to create and maintain functional API tests. Additionally, having the scripting functionality available encourages me to advocate the tool with others on our team who do have that scripting knowledge and prefer to write tests that way.”

“Great Automation with Katalon Experience. Katalon is a very useful and intuitive application. It enables me to easily record various types of automated test cases such as Web, Mobile, API and Desktop. I have been mostly creating test cases for Web UI applications in our Telecoms environment. We have been heavily testing our customer Service Management tool (Which is web based) using Katalon.”

“Katalon is Versatile and Beautiful. I like that Katalon is a singular tool that I can use for both frontend and API testing. I am able to automate API tests and validate them using test cases. I can also create test suites that I can run whenever I need to test multiple different functions of an application. I also like that I can program tests to perform differently depending on circumstances.”
