Expression that evaluates to the property key or array index.
For arrays: typically INumericLiteral for index access For objects: typically IStringLiteral for property key Can be any expression that evaluates to a valid key type
Examples:
The base expression being indexed/accessed.
Can be any expression that evaluates to an object or array. Typically represents collections or objects from captured API responses with dynamic properties.
Should reference previously captured data from API operations rather than direct API calls.
OptionalquestionWhether to use optional chaining (?.[]) operator.
True: Uses ?.[] for safe element access False: Uses [] for standard element access
Use optional chaining when the base expression might be null/undefined or when the accessed element might not exist in the captured data.
Type discriminator.
Element access expression for dynamic property access and array indexing.
Enables access to object properties using computed keys or array elements using indices. Useful for dynamic property access based on runtime values or when property names are not valid identifiers.
Primary use cases in E2E testing:
AI function calling context: Use when property access requires computation or when accessing array elements by index in captured data.
