Known Issues
If you're experiencing any of the below issues, please contact us at helpdesk@deque.com or support.deque.com. We will then be able to notify you once it's resolved or of an identified workaround if none is listed.
- axe DevTools Mobile automated testing runs on native iOS, native Android, and React Native applications. Please contact your Deque representative for accessibility testing solutions on your tech stack.
- While you may get some results from web views or rendered PDFs, we highly recommend testing using axe DevTools for Web or axe Monitor for the most comprehensive accessibility testing for the web.
iOS
Error in Analyzer Project & Testing by Bundle ID in 2.8.1
Functionality with testing an application by bundle identifier was broken in version 2.8.1 which resulted in an error titled "No target application path specified via test configuration: ...". Update to 2.8.2 or the latest version to resolve the error. Update to the latest within the iOS Analyzer project.
False Positive: LabelInName and LabelAtFront in SwiftUI & Cross Platform Apps
Some screens may report false positives with LabelInName and LabelAtFront due to an incorrect associatedText property being found (#1622)
Supports Dynamic Type rule not working with iOS 15 Pro simulator
There is an issue affecting the iPhone 15 Pro simulator that prevents the Supports Dynamic Type rule from running. If you are opted in to the Supports Dynamic Type rule, you will not be able to test it using an iPhone 15 Pro simulator. A bug has been filed with Apple.
Rules against Nested Controls
While looking at an improvement for our rules, we found that in XCTest, nested controls are not returned in the accessibility tree. A bug has been filed with Apple. (#1110)
ImageView Name Rule Needs Review Results for UIKit Apps
In UIKit apps, an image without an `accessibilityLabel` is not focusable with assistive technology by default.
The properties we use to check focusability from Apple may be inaccurate when an `accessibilityIdentifier` is set on the image. Due to this unexpected behavior, results for ImageView Name issues in UIKit apps will report as Needs Review. A bug report has been filed with Apple. (#1633)
False Positive: In Scroll View, Label In Name, Label at Front, and v2.11.0 Image View Name & ActiveControlName
We are actively working on fixes for the following false positives and will update this list as fixes are released.
In Scroll View
May report issues for text within banner-behaving elements. To make these elements available to those that require larger text, use UILargeContentViewer
. (#622)
v2.11.0 Image View Name & Active Control Name
If an UIImageView has an `accessibilityIdentifier` set but is not focusable by VoiceOver, and it has focusable controls nested within it, ActiveControlName may report a false positive on the UIImageView. Removing the `accessibilityIdentifier` resolves the issue. A bug has been filed with Apple. (#1633)
Label In Name and Label At Front
These two rules look for a control's visible label amongst nearby elements to help determine rule status. In some view hierarchies, the incorrect nearby text may be detected causing these rules to fail. (#1622)
Android
Analyzer App: Floating Action Button Disappears
Introduced with API 31 (Android 12) is the ability to hide non-system overlays. In order to utilize the axe Analyzer app, please ensure this setting is not turned on. If you have opted to utilize this feature for it's security enhancements, we recommend leaving it off for internal testing builds where you can safely utilize testing data and eliminate security concerns that way. Note: this setting does not affect Google's accessibility scanner app as it's considered a system overlay.
To utilize the axe Accessibility Analyzer app, update any calls to the method setHideOverlayWindows(true)
to setHideOverlayWindows(false)
on the affected activity windows.
Screenshot Missing (Black Box) in the Dashboard
To unlock full functionality of axe DevTools for Mobile, ensure screenshots are enabled. We recommend enabling screenshots on a debug or test version of your app that uses mock data to avoid security concerns. Checkout our guide for enabling screenshots in Android apps.
Crash when `minifiedEnabled` is set to true
If minifying your build, you'll see a crash with an error log reporting an adapter could not be found when trying to login to the axe DevTools library. Disable minify for your debug builds with axe DevTools implemented. (#729)
Builds with r8 enabled throw an error
A build with r8 enabled may attempt to minify the axeDevTools library resulting in an error similar to:
Caused by: java.lang.NullPointerException: throw with null exception at g.b.b.a$a.a(Unknown Source:1) at g.b.b.a$a.a(Unknown Source:0) at g.b.b.a.a(AccessToken.java:190)To resolve this error add the following line to your ProGuard file to keep axeDevTools classes:
keep class com.deque.** { *; }
Error message similar to:
Expected exactly '1' node but found '2' nodes that satisfy: (isRoot)
or: No View initialized, did you call AxeDevToolsCompose.setComposeTestRule()?
If you encounter an error along the lines of `Expected exactly '1' node but found '2' nodes that satisfy: (isRoot)` or `No View initialized, did you call AxeDevToolsCompose.setComposeTestRule()?`, please refer to Compose setTestTag API.
Log message:MlKitContext has not been initialized
If you encounter this message, some rule results may not return as expected when that rule is utilizing artificial intelligence. Affected rules include Color Contrast, Focusable Text and Nested Element Name. (#841)
MAUI: Edit Text Name rule
Due to limitations of the MAUI app architecture rendering in the Android ecosystem, the Edit Text Name rule will show as Needs Review in the dashboard when a failure is suspected for SDK version 5.5.0 and up. Please confirm correct behavior manually for this case.
Native Android: Custom Dialogs / Modals
When you're implementing custom dialogs or modals that do not extend the native controls, you may get results for views behind the modal. In this case, we recommend not running our tool against these custom modals or dialogs and instead manually checking them to ensure they behave with assistive technology as desired.
Web Dashboard
Missing Screenshot
If the screenshot is missing from the scan details page, your app may be preventing screenshots from being taken. Often this is for security reasons in your production application. Consider removing this requirement for your testing build to allow for full functionality in the axe DevTools Mobile Dashboard.
Some Android scan names are unformatted
Some Android scan names that are defaulted to the screen title will appear as the full class name including the bundle identifier. In a future release, this will be resolved so that the screen title is formatted into a more readable name. As a workaround, you can set the scan name from the dashboard or frameworks. (#1643)
Appium Plugin
False Positives: Active View Name, Touch Target Spacing
We are actively working on fixes for the following false positives and will update this list as fixes are released.
Active View Name
Due to limitations in information available via the Appium platform, we've identified a false positive for Active View Name when using the labeledBy
property to provide a label for a button element.
Touch Target Spacing on iOS platform for SwiftUI & React Native apps
Larger controls may fail Touch Target Spacing when they are greater than the minimum 24pt x 24pt requirement. (#411)
False Negative: Inaccessible Action on Android React Native
You may see contradictory results for this new rule when scanning React Native apps on the Android platform. Some views will have a nested button element resulting in a failure for the parent button, but a pass in the child button. (#407)
React Native: Label In Name & Label At Front
Due to limitations in information available via the Appium platform, we've identified the Label In Name & Label At Front rules aren't able to run for apps built with React Native. We are exploring solutions and expect a fix in a future release.
React Native & .NET MAUI: Inspect View Hierarchy Showing Past Screen
Sometimes the Appium page source property needs extra time to get updated between scans. If this happens, you'll see a previous screen's view hierarchy when using the inspect feature on the dashboard. To fix, add a small timeout before calling the page source API to prompt the accessibility scan. Example:
await driver.pause(1000); const result = await driver.getPageSource();
Limitation: Image View Name for Decorative Images in Android
Due to limitations in information available via the Appium platform, we've identified the Image View Name rule is unable to accurately test for decorative image success criteria in Android. Results for images without an accessible name will display as 'Needs Review' in the dashboard for further analysis.
