Karate Files

Important Fixes

• ##(schema) optional-marker semantics now apply to schema references — a null value passes [#3006]
• The method keyword resolves variables again (v2 regression) [#2997]
• karate.sort(list) works with a single argument as documented — the key function is optional [#2996]
• get[0] with a JsonPath filter returns [] instead of erroring when the path traverses a null node [#2995]
• call / callonce with read() no longer drops a callee-defined key that shares a name with a caller variable [#2991]
• NDJSON response bodies are kept as raw text instead of being silently truncated by JSON parsing [#2990]
• afterScenario hook scope is no longer frozen to the first scenario when Background uses callonce with HTTP [#2988]
• set accepts a multi-line docstring expression [#2978]
• text/plain responses are no longer parsed as JSON just because the body starts with a brace [#2977]
• #(!^part) schema macro no longer false-passes on a list of objects [#2976]
• match contains only deep respects element multiplicity instead of matching differing multisets [#2975]
• Numeric match == no longer equates distinct integers above 2^53 [#2974]
• karate.callSingle / karate.call arguments are passed consistently to classpath: JS functions across scenarios [#2973]
• OOM under parallel execution fixed — embedded-expression processing no longer deep-copies every variable in scope on every step [#2972]
• Report keeps per-step / HTTP detail for karate.callSingle() calls made during karate-config.js resolution [#2967]

New Features & Enhancements

• JS engine: async / await / Promise runtime with setTimeout support
• JS engine: private class fields, methods and accessors; WeakMap / WeakSet; labeled statements with break / continue
• JS engine: significant performance work — slot-frame resolution for function locals, token caches, static binary operators
• Image: new pixelmatch comparison engine with cluster verdict and ignoredBoxes [#2987]
• HTTP: csv, yaml, toml and markdown are recognized named content-types
• Mocks: a Karate mock discloses itself on the wire via a Karate-Mock response header
• Gatling: failure detail aligned across the KO message and log output [#2998]
• Memory: a step's captured logs and embeds are released at feature end, and suite-exit no longer re-ships the whole run
• A dry run no longer prints as a green pass, and its result says so
• A missing karate-config.js is logged at INFO instead of WARN
• Dependency bumps: jackson-bom 2.22.1
