The following topic lists error messages that occur during the upload of XCTest UI tests and recommends workarounds to resolve each error.

Note

The instructions below are based on Linux x86_64 and Mac.

XCTEST_UI_TEST_PACKAGE_UNZIP_FAILED

If you see the following message, follow these steps to fix the issue.

Warning

We could not open your test IPA file. Please verify that the file is valid and try again.

Make sure that you can unzip the application package without errors. In the following example, the package's name is swift-sample-UI.ipa.

  1. Copy your test package to your working directory, and then run the following command:

    Copy
    $ unzip swift-sample-UI.ipa
  2. After you successfully unzip the package, you can find the working directory tree structure by running the following command:

    Copy
    $ tree .

    A valid iOS application package should produce output like the following:

    Copy
    . `-- Payload (directory) `-- swift-sampleUITests-Runner.app (directory) |-- Info.plist |-- Plugins (directory) | `swift-sampleUITests.xctest (directory) | |-- Info.plist | `-- (any other files) `-- (any other files)

    For more information, see XCTest UI.
