Plane API Testing Framework

A composable API for testing Plane's customer APIs with chainable operations.
Build any test flow with method calls across different API domains.

Examples:
    # Simple customer operations
    api.customers().create("Acme Corp").update({"description": "Updated"}).run()

    # Cross-domain composition
    api.customers().create("Acme").properties().create("Status", "OPTION", ["Active", "Inactive"]).run()

    # With context variables and mock mode
    api.mock().customers().create("Test Corp").as_("main_customer").properties().create("Tier").run()
