WPT analysis

Review the listed WPT paths for AbortSignal, Web Crypto API, Console, Streams, compression, encoding, URL, URLPattern, and File API. Investigate streams/transferable/* and the FileReader dependency, then determine whether HTML and area element tests should be split. Done means the WPT coverage gaps and proposed test changes are resolved.

AbortSignal

• AbortController
• AbortSignal

+dom/abort/*
-dom/abort/reason-constructor.html

Web Crypto API

• Crypto
• CryptoKey
• SubtleCrypto
• globalThis.crypto

+WebCryptoAPI/*
-historical.any.*
-algorithm-discards-context.https.window.*

Console

• globalThis.console

+console/*

Tests are very sparse, and so is spec - it is unclear what side-effects console.log should have across runtimes.

Streams

• ByteLengthQueuingStrategy
• CountQueuingStrategy
• ReadableByteStreamController
• ReadableStream
• ReadableStreamBYOBReader
• ReadableStreamBYOBRequest
• ReadableStreamDefaultController
• ReadableStreamDefaultReader
• TransformStream
• TransformStreamDefaultController
• WritableStream
• WritableStreamDefaultController
• WritableStreamDefaultWriter

+streams/*
-streams/readable-streams/cross-realm-crash.window.html

streams/transferable/* needs investigation.

(De)compression streams

• CompressionStream
• DecompressionStream

+compression/*

Text encoding

• TextDecoder
• TextDecoderStream
• TextEncoder
• TextEncoderStream

+encoding/*
-encoding/streams/realms.window.html
-encoding/streams/invalid-realm.window.html
-encoding/unsupported-encodings.any.*
-encoding/single-byte-decoder.window.html
-encoding/unsupported-labels.window.html

URL

• URL
• URLSearchParams

+url/*
-url/url-setters-a-area.window.html
-url/a-element-origin.html
-url/a-element.html
-url/data-uri-fragment.html
-url/failure.html

Note, a lot of tests in this directory also test using <a> and <area> tags from HTML. It would be good to split those into seperate files.

URLPattern

• URLPattern

+urlpattern/urlpattern.any.*
+urlpattern/urlpattern-https.any.*
+urlpattern/urlpattern-hasregexpgroups.any.*

File API

• Blob
• File

+FileAPI/blob/*
-FileAPI/blob/Blob-constructor-dom.window.html
+FileAPI/file/*
-FileAPI/file/send-file-form-*
+FileAPI/url/url-format.any.*
+FileAPI/url/url-with-fetch.any.*
+FileAPI/unicode.html

A lot of these tests rely on FileReader existing. Should we add this?
