Troubleshooting instrumentation tests in AWS Device Farm

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

Note

For important considerations when using Instrumentation tests in AWS Device Farm, see Instrumentation for Android and AWS Device Farm.

INSTRUMENTATION_TEST_PACKAGE_UNZIP_FAILED

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

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

Make sure that you can unzip the test package without errors. In the following example, the package's name is app-debug-androidTest-unaligned.apk.

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

    $ unzip app-debug-androidTest-unaligned.apk

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

    $ tree .

    A valid Instrumentation test package will produce output like the following:

    .
|-- AndroidManifest.xml
|--  classes.dex
|-- resources.arsc
|-- LICENSE-junit.txt
|-- junit (directory)
`-- META-INF (directory)

INSTRUMENTATION_TEST_PACKAGE_AAPT_DEBUG_BADGING_FAILED

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

We could not extract information about your test package. Please verify that the
      test package is valid by running the command "aapt debug badging <path to your test
      package>", and try again after the command does not print any error.

During the upload validation process, Device Farm parses out information from the output of the aapt debug badging <path to your package> command.

Make sure that you can run this command on your Instrumentation test package successfully.

In the following example, the package's name is app-debug-androidTest-unaligned.apk.

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

    $ aapt debug badging app-debug-androidTest-unaligned.apk

    A valid Instrumentation test package will produce output like the following:

    package: name='com.amazon.aws.adf.android.referenceapp.test' versionCode='' versionName='' platformBuildVersionName='5.1.1-1819727'
sdkVersion:'9'
targetSdkVersion:'22'
application-label:'Test-api'
application: label='Test-api' icon=''
application-debuggable
uses-library:'android.test.runner'

INSTRUMENTATION_TEST_PACKAGE_INSTRUMENTATION_RUNNER_VALUE_MISSING

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

We could not find the instrumentation runner value in the AndroidManifest.xml.
      Please verify the test package is valid by running the command "aapt dump xmltree <path to
      your test package> AndroidManifest.xml", and try again after finding the instrumentation
      runner value behind the keyword "instrumentation."

During the upload validation process, Device Farm parses out the instrumentation runner value from the XML parse tree for an XML file contained within the package. You can use the following command: aapt dump xmltree <path to your package> AndroidManifest.xml.

Make sure that you can run this command on your Instrumentation test package and find the instrumentation value successfully.

In the following example, the package's name is app-debug-androidTest-unaligned.apk.

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

    $ aapt dump xmltree app-debug-androidTest-unaligned.apk AndroidManifest.xml | grep -A5 "instrumentation"

    A valid Instrumentation test package will produce output like the following:

    E: instrumentation (line=9)
      A: android:label(0x01010001)="Tests for com.amazon.aws.adf.android.referenceapp" (Raw: "Tests for com.amazon.aws.adf.android.referenceapp")

INSTRUMENTATION_TEST_PACKAGE_AAPT_DUMP_XMLTREE_FAILED

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

We could not find the valid AndroidManifest.xml in your test package. Please
      verify that the test package is valid by running the command "aapt dump xmltree <path to
      your test package> AndroidManifest.xml", and try again after the command does not print any
      error.

During the upload validation process, Device Farm parses out information from the XML parse tree for an XML file contained within the package using the following command: aapt dump xmltree <path to your package> AndroidManifest.xml.

Make sure that you can run this command on your instrumentation test package successfully.

In the following example, the package's name is app-debug-androidTest-unaligned.apk.

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

    $ aapt dump xmltree app-debug-androidTest-unaligned.apk AndroidManifest.xml

    A valid Instrumentation test package will produce output like the following:

    N: android=http://schemas.android.com/apk/res/android

INSTRUMENTATION_TEST_PACKAGE_TEST_PACKAGE_NAME_VALUE_MISSING

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

We could not find the package name in your test package. Please verify that the
      test package is valid by running the command "aapt debug badging <path to your test
      package>", and try again after finding the package name value behind the keyword "package:
      name."

During the upload validation process, Device Farm parses out the package name value from the output of the following command: aapt debug badging <path to your package>.

Make sure that you can run this command on your Instrumentation test package and find the package name value successfully.

In the following example, the package's name is app-debug-androidTest-unaligned.apk.

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

    $ aapt debug badging app-debug-androidTest-unaligned.apk | grep "package: name="

    A valid Instrumentation test package will produce output like the following:

    package: name='com.amazon.aws.adf.android.referenceapp.test' versionCode='' versionName='' platformBuildVersionName='5.1.1-1819727'
