Katalon Comparison Card Aspect/ Feature Katalon HyperTest What does it do? End to end automation including UI and API Complete backend testing: APIs, database calls, message queues & inter-service contracts Who are its users? Will not test database calls, async flows or message queues. Only Developers What will it not do? SDETs, test and QA engineers Front-end testing: will not test UI or test across browsers or devices How to start? Katalon Studio. Provides a comprehensive IDE for writing, recording, and executing tests 10-line SDK in the source code of repo. Records traffic and builds tests which can be replayed later using CLI How does it work? Recording and Scripting: Users can record their actions on web or mobile applications, generating automated test scripts. They can also write custom scripts using Groovy Record and Replay: Monitors application traffic using its SDK to generate backend tests automatically. 100% autonomous. Where does it run tests? Katalon Cloud. Needs dedicated and test isolated environments with SUT and dependencies available Environment Agnostic. No dedicated or isolated environments needed. These tests can be run locally 100% local or before push-commit in CI Maintenance Manual. Write and update tests using Katalon Studio manually 100% autonomous or no-code. Automatically generates tests by recording actual user flows. Auto updates all test cases and assertions as APIs change Quality of Tests Poor. Depends on quality of assertions which are manually written High. Quality programmatically generated assertions that cover schema & data to never miss errors Test Coverage Unknown. No way to measure test coverage that can result in poor coverage and untested scenarios Measurable. Reports code coverage i.e. actual lines tested lines of code leaving behind no untested scenario Test Data Management Yes. users need to use data sheets or custom scripts to seed and manipulate data for tests. Can turn out to be non-trivial No. HyperTest uses data from traffic for tests and keeps it reusable. Handles both read & write requests Test Execution Speed High. API test: Depends on response time of API and run environment End to end test: Take longer to run Negligible. Runs as fast as unit tests. Does not need dedicated environments but are still able to test e2e backend flows Can it test databases? No Yes Can it test message queues? No Yes Prevent Logical bugs in your database calls, queues and external APIs or services Get Started for Free
