Best for

✓ Best for

Teams practicing BDD (Behavior-Driven Development) who need a flexible test automation framework
Projects requiring extensive API testing with REST or SOAP protocols
Agile teams that value readable and maintainable test cases

✓ Best for

Developers who need to automate browser actions across multiple platforms and browsers.
Test teams looking to ensure cross-browser compatibility of web applications.

Not ideal for

✕ Not for

Scenarios where real-time performance is critical, as Robot Framework may not be optimized for speed
Teams looking for a fully managed cloud-based testing service without self-hosting requirements

✕ Not for

Projects that require real-time interaction with the browser, as Selenium is more suited for batch processing tasks.
Scenarios where performance is critical, as Selenium can be slower compared to headless browser solutions.
