Bug 286763

imported/w3c/webdriver/tests/bidi/session/subscribe/invalid.py imported/w3c/webdriver/tests/bidi/session/unsubscribe/invalid.py For example, currently we just check if "events" is an array and, for each element get `eventName->asString()`, while the spec expects the name to be actually a string, and a valid module or event name. Non-Comprehensive list of test cases from wpt: - Empty parameters should raise InvalidArgument - Invalid "events" parameter type (i.e. non-array) should raise InvalidArgument - "events" as an empty array should raise InvalidArgument - Invalid "events" values types (non-string) should raise InvalidArgument - "events" values that refer to unknown events should raise InvalidArgument - Mixing known and unknown events should, not subscribe to the known event - Raise InvalidArgument - Invalid "contexts" parameter type (i.e. non-array) should raise InvalidArgument - "contexts" as an empty array should raise InvalidArgument - Invalid "context" values types (non-string) should raise InvalidArgument - Invalid "context" value (e.g. non-existing frame) should raise NoSuchFrame - Valid event and invalid context should not subscribe to the event, raising NoSuchFrame - Trying to subscribe to a context of a closed tab should raise NoSuchFrame
