Overview

Test adapter that returns schema-conformant placeholder values without calling any LLM API. Useful for testing flows that include LLM steps.

For extract steps with a schema, returns a hash of default values matching each field's declared type. Fields constrained to a list of allowed values (enum/multi_enum resolved from questions) return the first allowed value, so placeholders stay valid answers for the downstream question. Without a schema, returns a placeholder string.

Examples:

adapter = Inquirex::LLM::NullAdapter.new
result = adapter.call(extract_node, answers)
# => { industry: "", employee_count: 0, entity_type: "llc", ... }
