Load Testing Capabilities: Some reviewers mention successful use of SoapUI for performance and load testing, especially in enterprise environments.
Data-Driven Testing: Users find it helpful for running tests with multiple data sets, improving coverage and reliability.
Mock Services: The ability to simulate APIs using mock services is seen as a major advantage during early development stages.
Ease of Scripting: The use of Groovy scripting is highlighted as intuitive and powerful, allowing for flexible test automation.
Free and Open Source: Many appreciate that the core version is free to use, which is especially beneficial for small teams and individual developers.
Window Management: Users dislike that each request opens in a separate window, making it hard to manage multiple test cases.
Limited Free Features: While SoapUI is free, several advanced features are locked behind the ReadyAPI paywall, which can be frustrating for users wanting more functionality.
Performance Issues: Some users report lag or crashes when handling large projects or complex test suites.
Steep Learning Curve: New users often find it difficult to navigate and locate specific features without prior experience.
Outdated UI: A common complaint is that the user interface feels cluttered and dated, especially compared to modern tools like Postman.
