Pull request overview

This PR migrates WebDriver Atoms from Google Closure Library to TypeScript, implementing approximately 16 modules across storage, core atoms, inject wrappers, and exports. The migration includes new BUILD.bazel files, TypeScript configuration, and comprehensive implementation of storage APIs (localStorage, sessionStorage, AppCache), element manipulation, attribute handling, and input simulation.

Changes:

  • Migration of WebDriver atoms from Closure to TypeScript with proper type safety
  • New directory structure: javascript/webdriver-atoms-ts/src/ and javascript/atoms-ts/src/
  • BUILD.bazel configuration for ts_project targets with proper dependencies
  • Storage modules (local_storage, session_storage, appcache) with complete implementations
  • Core modules (element, attribute, inputs) for WebDriver operations
  • Inject wrappers for script injection and element operations

All action functions (type, submit, clear, click, doubleClick, rightClick) call executeActionFunction() which returns stub implementations with null values. These functions need actual implementations that deserialize elements from the cache and execute the corresponding actions from the atoms-ts action module.

The performSearch function contains only placeholder logic with comments indicating what a real implementation would do. It needs to actually deserialize the root element, use the strategy and locator to find elements, serialize found elements, cache them, and return their cache keys - not just return empty/null values.

The type function has a parameter _keyboard?: Keyboard with an underscore prefix (indicating it's intentionally unused), but the function doesn't actually use the provided keyboard instance. Instead, it directly manipulates sequences and calls action.type. This breaks the API contract - if a keyboard instance is provided, it should be used for the typing operations.

Many inject functions return stub implementations with placeholder empty values. For example, findElement returns { status: 0, value: null } and getText calls executeDomFunction() which always returns null. These functions need actual implementations that perform their intended operations (finding elements, getting text, etc.) rather than returning placeholder responses.

The executeSql function contains only a stub implementation with placeholder comments. Real SQL execution logic is missing - it should actually open the database, create a transaction, execute the query with provided arguments, and handle results/errors properly. The current implementation just returns empty results regardless of the query.

- Replace 3 JavaScript atoms with TypeScript versions:
  * getAttribute: //javascript/webdriver/atoms → //javascript/webdriver-atoms-ts/src:attribute
  * isDisplayed: //javascript/atoms/fragments → //javascript/webdriver-atoms-ts/src:dom
  * findElements: //javascript/atoms/fragments → //javascript/webdriver-atoms-ts/src:find_element

- Add select_file rules to extract specific .js outputs from multi-output ts_project targets
- Update visibility in webdriver-atoms-ts to public for cross-package access
- Build verified: bazel build //py:selenium completes successfully

This integrates the new type-safe TypeScript atoms into the Python WebDriver,
replacing old JavaScript atom implementations with the new atoms-ts versions.

There's a syntax error in the decorator call on line 322. The decorator should be @pytest.mark.xfail_wpewebkit() (with empty parentheses) to match the pattern used on line 299-301, but instead it has an extra set of parentheses: @pytest.mark.xfail_wpewebkit()(). This will cause a runtime error when the test file is loaded.

The return type annotation should match the return type of the imported function. The isDisplayed function at line 98 in inject/dom.ts returns string (stringified response), not string as a direct value. However, if dom.isDisplayed from line 2 returns a boolean, this wrapper should return boolean, not string. The type annotation is inconsistent with the actual return value.

There are open questions that need a village to help me answer.

  • Do we care about the "html5" features that a lot of browsers have deprecated/never implemented/deleted implementations like appcache/web SQL?
  • What browsers do we care about supporting? We have logic for IE 10 and under in there
  • What versions of Android/iOS do we care about supporting? We have logic for Android IceCream (what year is it.gif)
  • What atoms do we actually care about supporting vs we have dead code and we have no way of knowing what needs supporting/removing

- Restructured findElement/findElements to delegate to performSearch_ with search functions
- Implemented locateSingleElement and locateMultipleElements search function wrappers
- Separated response handling into wrapResponse and wrapError functions
- Changed locator format to object style: {strategy: using} to match Closure
- Added SearchFunction type for polymorphic search function signatures
- Renamed optional parameter _optWindow with underscore prefix to document intentional non-use
- All TypeScript compilation errors resolved (0 errors)
- Builds successfully with no breaking changes
- Maintains API compatibility with WebDriver protocol
…format

- Added 'locators/*.ts' and 'locators/**/*.ts' to the find_element_bundle glob pattern in BUILD.bazel
  This ensures that locator strategy files are included when building the find_element_bundle,
  which was causing the 'Unexpected token ;' JavaScript error due to missing module imports

- Fixed malformed JSDoc comment in exports/index.ts that was missing proper formatting
  Changed from 'Element locator strategies and finder functions. */' to proper multi-line format

The find_element_bundle imports from ../locators/index.ts which was not being included in the esbuild
process, causing esbuild to fail to resolve the imports and generate malformed JavaScript.

Some updates from Appium side.

  • We use these selenium atoms ONLY for Mobile Safari on iOS.
  • We only officially cover two most recent major iOS releases. The compatibility to older versions is possible, but not guaranteed or tested
  • Here you can find the full list of atoms that are available for usage: https://github.com/appium/appium-remote-debugger/tree/master/atoms, although not all of them seem to be used for now. Below I have added more detailed analysis made by cursor based on the present codebase.

Atoms that are used

Atom file Where it's used
active_element.js general.ts – active element
clear.js element.ts – clear element
click.js gesture.ts, element.ts – click
execute_async_script.js executeAtomAsync (and tests)
execute_script.js execute.ts, web.ts, element.ts, source.ts, navigation.ts, general.ts, screenshot.ts, execute mixin
find_element.js remote-debugger tests (shadow DOM)
find_element_fragment.js web.ts (find in fragment), tests
find_elements.js web.ts (find many)
frame_by_id_or_name.js web.ts (switch frame by name/id), tests
frame_by_index.js web.ts (switch frame by index)
get_attribute_value.js element.ts, web.ts – attribute/property and native tap fallback
get_element_from_cache.js lib/atoms.ts – frame script wrapping (internal)
get_frame_window.js web.ts – frame window for navigation
get_size.js web.ts, screenshots.ts, element.ts
get_text.js element.ts, web.ts (native tap path), tests
get_top_left_coordinates.js web.ts, screenshots.ts, element.ts
get_value_of_css_property.js web.ts – CSS property value
is_displayed.js element.ts
is_enabled.js element.ts
is_selected.js element.ts
submit.js web.ts – form submit
type.js element.ts, tests

So 22 atom files in ./atoms are actually used (by xcuitest-driver and/or remote-debugger).


Atoms that are not used

These files exist in ./atoms but are never referenced in appium-xcuitest-driver/lib or in the remote-debugger code/tests I checked:

Unused atom file
clear_local_storage.js
clear_session_storage.js
default_content.js
execute_sql.js
get_appcache_status.js
get_attribute.js
get_effective_style.js
get_local_storage_item.js
get_local_storage_key.js
get_local_storage_keys.js
get_local_storage_size.js
get_location.js
get_session_storage_item.js
get_session_storage_key.js
get_session_storage_keys.js
get_session_storage_size.js
is_editable.js
is_focusable.js
is_interactable.js
remove_local_storage_item.js
remove_session_storage_item.js
set_local_storage_item.js
set_session_storage_item.js

So 23 atom files in ./atoms appear unused. The only “storage”/DB-style atoms used in the driver are the generic execute_script / execute_async_script; the dedicated local/session storage and SQL atoms are not called.

We do not support IE 10. We technically support IE 11 via IE Mode in Edge, but I would be surprised if we ever did another IE Driver release. We could consider making that official with Selenium 5; we haven't touched IE Driver code in over 2 years, and I think Microsoft is in security-updates-only mode on it.

Looks like Google first applies their own patch to our code (https://chromium.googlesource.com/chromium/src/+/refs/heads/main/third_party/selenium-atoms/patch.diff) before building what's in javascript/chrome-driver.

Did an AI review of chromedriver code compared to what we build in javascript/chromed-driver/BUILD.bazel.
These are the things we build that it uses:

  • :find-element-chrome
  • :get-location-chrome
  • :get-location-in-view-chrome
  • :is-element-clickable-chrome
  • //javascript/atoms/fragments:clear-chrome
  • //javascript/atoms/fragments:click-chrome
  • //javascript/atoms/fragments:find-elements-chrome
  • //javascript/atoms/fragments:get-effective-style-chrome
  • //javascript/atoms/fragments:get-size-chrome
  • //javascript/atoms/fragments:is-displayed-chrome
  • //javascript/atoms/fragments:is-enabled-chrome
  • //javascript/atoms/fragments:submit-chrome
  • //javascript/webdriver/atoms:get-attribute-chrome
  • //javascript/webdriver/atoms:get-text-chrome
  • //javascript/webdriver/atoms:is-selected-chrome

These are the things that we are building but are not referenced:

  • :get-first-client-rect-chrome
  • :get-page-zoom-chrome
  • :is-element-displayed-chrome
  • //javascript/atoms/fragments:execute-async-script-chrome
  • //javascript/atoms/fragments:execute-script-chrome

  • //javascript/webdriver/atoms:clear-local-storage-chrome

One note from the Appium perspective: it would be ideal if the built atoms were simply made available as an NPM package we could consume. That would greatly simplify how we make them available as part of Appium.

many() currently parses/validates the criteria but then always returns an empty array as a placeholder. Python uses findElements.js specifically to implement RelativeBy; returning [] here will make relative locators always find nothing. This strategy needs a real implementation or should throw a clear error so failures are obvious.

This implementation relies on CSS.escape() for escaping IDs/names in selectors. CSS.escape is not available in all browsers Selenium supports, and it also isn't the right escaping for attribute selector string values. The existing atoms code uses its own escaping logic; consider reusing that approach here (or avoid querySelector for these cases) to preserve cross-browser behavior.

@pytest.mark.xfail_wpewebkit()( is invalid decorator syntax and will raise at import time (it calls the marker and then tries to call the result). It should be a single decorator call like the other xfail markers (pass raises/reason directly).

type() ignores the passed Keyboard instance (_keyboard is unused) and calls action.type(...) directly. This breaks the contract used by inputs.sendKeys, which expects webdriver.atoms.element.type to update the provided keyboard state so the caller can return the correct keyboard.getState() (e.g., for persisted modifiers). Consider routing key dispatch through the Keyboard instance (as the Closure implementation does) or remove the stateful API if it’s not supported.

There’s a commented-out requirement("debugpy") entry inside TEST_DEPS. If this was only for local debugging, it should be removed to keep the BUILD file clean (and avoid buildifier churn). If it’s required, it should be added as an active dependency instead of commented.
