Troubleshooting XCTest tests in AWS Device Farm

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

Note

The instructions below assume you are using MacOS.

XCTEST_TEST_PACKAGE_UNZIP_FAILED

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

Warning

We could not open your test ZIP 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 swiftExampleTests.xctest-1.zip.

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

   $ unzip swiftExampleTests.xctest-1.zip

2. After you successfully unzip the package, you can find the working directory tree structure by running the following command:

   $ tree .

   A valid XCTest package should produce output like the following:

   .
   `-- swiftExampleTests.xctest (directory)
                 |-- Info.plist
                 `-- (any other files)

   For more information, see Working with XCTest for iOS and AWS Device Farm.

XCTEST_TEST_PACKAGE_XCTEST_DIR_MISSING

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

Warning

We could not find the .xctest directory inside your test package. Please unzip your test package, verify that the .xctest directory is inside the package, and try again.

In the following example, the package's name is swiftExampleTests.xctest-1.zip.

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

   $ unzip swiftExampleTests.xctest-1.zip

2. After you successfully unzip the package, you can find the working directory tree structure by running the following command:

   $ tree .

   If the XCTest package is valid, you will find a directory with a name similar to swiftExampleTests.xctest inside the working directory. The name should end with .xctest.

   .
   `-- swiftExampleTests.xctest (directory)
                 |-- Info.plist
                 `-- (any other files)

   For more information, see Working with XCTest for iOS and AWS Device Farm.

XCTEST_TEST_PACKAGE_PLIST_FILE_MISSING

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

Warning

We could not find the Info.plist file inside the .xctest directory. Please unzip your test package and then open the .xctest directory, verify that the Info.plist file is inside the directory, and try again.

In the following example, the package's name is swiftExampleTests.xctest-1.zip.

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

   $ unzip swiftExampleTests.xctest-1.zip

2. After you successfully unzip the package, you can find the working directory tree structure by running the following command:

   $ tree .

   If the XCTest package is valid, you will find the Info.plist file inside the .xctest directory. In our example below, the directory is called swiftExampleTests.xctest.

   .
   `-- swiftExampleTests.xctest (directory)
                 |-- Info.plist
                 `-- (any other files)

XCTEST_TEST_PACKAGE_PACKAGE_NAME_VALUE_MISSING

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

Warning

We could not find the package name value in the Info.plist file. Please unzip your test package and then open Info.plist file, verify that the key "CFBundleIdentifier" is specified, and try again.

In the following example, the package's name is swiftExampleTests.xctest-1.zip.

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

   $ unzip swiftExampleTests.xctest-1.zip

2. After you successfully unzip the package, you can find the working directory tree structure by running the following command:

   $ tree .

   You should find the Info.plist file inside an .xctest directory like swiftExampleTests.xctest in our example:

   .
   `-- swiftExampleTests.xctest (directory)
                 |-- Info.plist
                 `-- (any other files)

3. To find the package name value, you can open Info.plist using Xcode or Python.

   For Python, you can install the biplist module by running the following command:

   $ pip install biplist

4. Next, open Python and run the following command:

   import biplist
   info_plist = biplist.readPlist('swiftExampleTests.xctest/Info.plist')
   print info_plist['CFBundleIdentifier']

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

   com.amazon.kanapka.swiftExampleTests

XCTEST_TEST_PACKAGE_EXECUTABLE_VALUE_MISSING

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

Warning

In the following example, the package's name is swiftExampleTests.xctest-1.zip.

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

   $ unzip swiftExampleTests.xctest-1.zip

2. After you successfully unzip the package, you can find the working directory tree structure by running the following command:

   $ tree .

   You should find the Info.plist file inside an .xctest directory like swiftExampleTests.xctest in our example:

   .
   `-- swiftExampleTests.xctest (directory)
                 |-- Info.plist
                 `-- (any other files)

3. To find the package name value, you can open Info.plist using Xcode or Python.

   For Python, you can install the biplist module by running the following command:

   $ pip install biplist

4. Next, open Python and run the following command:

   import biplist
   info_plist = biplist.readPlist('swiftExampleTests.xctest/Info.plist')
   print info_plist['CFBundleExecutable']

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

   swiftExampleTests
