Robot Framework
Robot Framework is an open-source, keyword-driven test automation framework using a simple, tabular syntax readable by non-programmers, extensible through libraries written in Python or Java. It's popular for both UI and API test automation, especially in teams mixing technical and non-technical testers.
Test cases in Robot Framework are written as sequences of keywords in a plain-text or spreadsheet-like format — `Click Element`, `Input Text`, `Element Should Be Visible` — each backed by library code, similar in spirit to keyword-driven testing generally, but Robot Framework is a specific, mature, widely-adopted implementation of that idea.
Its extensibility is a major strength: teams can write custom keywords in Python to wrap complex or domain-specific actions, then expose those to non-programmer testers as simple, readable steps — letting technical and non-technical team members collaborate on the same test suite without either side needing to learn the other's full skill set.
