Troubleshooting Appium Python tests in AWS Device Farm

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

APPIUM_PYTHON_TEST_PACKAGE_UNZIP_FAILED

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

Warning

We could not open your Appium test ZIP 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 test_bundle.zip.

Copy your test package to your working directory, and then run the following command:
```
$ unzip test_bundle.zip
```

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


$ tree .

A valid Appium Python package should produce output like the following:


.
|-- requirements.txt
|-- test_bundle.zip
|-- tests (directory)
|      `-- test_unittest.py
`-- wheelhouse (directory)
       |-- Appium_Python_Client-0.20-cp27-none-any.whl
       |-- py-1.4.31-py2.py3-none-any.whl
       |-- pytest-2.9.0-py2.py3-none-any.whl
       |-- selenium-2.52.0-cp27-none-any.whl
       `-- wheel-0.26.0-py2.py3-none-any.whl

APPIUM_PYTHON_TEST_PACKAGE_DEPENDENCY_WHEEL_MISSING

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

Warning

We could not find a dependency wheel file in the wheelhouse directory tree. Please unzip your test package and then open the wheelhouse directory, verify that at least one wheel file is in the directory, and try again.

Make sure that you can unzip the test package without errors. In the following example, the package's name is test_bundle.zip.

Copy your test package to your working directory, and then run the following command:
```
$ unzip test_bundle.zip
```

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


$ tree .

If the Appium Python package is valid, you will find at least one .whl dependent file like the highlighted files inside the wheelhouse directory.


.

APPIUM_PYTHON_TEST_PACKAGE_INVALID_PLATFORM

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

Warning

We found at least one wheel file specified a platform that we do not support. Please unzip your test package and then open the wheelhouse directory, verify that names of wheel files end with -any.whl or -linux_x86_64.whl, and try again.

Make sure that you can unzip the test package without errors. In the following example, the package's name is test_bundle.zip.

After you successfully unzip the package, you can find the working directory tree structure by running the following command:
```
$ tree .
```
If the Appium Python package is valid, you will find at least one .whl dependent file like the highlighted files inside the wheelhouse directory. The file's name may be different, but it should end with -any.whl or -linux_x86_64.whl, which specifies the platform. Any other platforms like windows are not supported.

APPIUM_PYTHON_TEST_PACKAGE_INSTALL_DEPENDENCY_WHEELS_FAILED

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

Warning

We failed to install the dependency wheels. Please unzip your test package and then open the requirements.txt file and the wheelhouse directory, verify that the dependency wheels specified in the requirements.txt file exactly match the dependency wheels inside the wheelhouse directory, and try again.

We strongly recommend that you set up Python virtualenv for packaging tests. Here is an example flow of creating a virtual environment using Python virtualenv and then activating it:


$ virtualenv workspace
$ cd workspace 
$ source bin/activate

Make sure that you can unzip the test package without errors. In the following example, the package's name is test_bundle.zip.

Copy your test package to your working directory, and then run the following command:
```
$ unzip test_bundle.zip
```

To test installing wheel files, you can run the following command:


$ pip install --use-wheel --no-index --find-links=./wheelhouse --requirement=./requirements.txt

A valid Appium Python package should produce output like the following:


Ignoring indexes: https://pypi.python.org/simple

To deactivate the virtual environment, you can run the following command:
```
$ deactivate
```
For more information, see Appium tests and AWS Device Farm.

APPIUM_PYTHON_TEST_PACKAGE_PYTEST_COLLECT_FAILED

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

Warning

We failed to collect tests in the tests directory. Please unzip your test package, very that the test package is valid by running the command py.test --collect-only <path to your tests directory>, and try again after the command does not print any error.

We strongly recommend that you set up Python virtualenv for packaging tests. Here is an example flow of creating a virtual environment using Python virtualenv and then activating it:


$ virtualenv workspace
$ cd workspace 
$ source bin/activate

Make sure that you can unzip the test package without errors. In the following example, the package's name is test_bundle.zip.

Copy your test package to your working directory, and then run the following command:
```
$ unzip test_bundle.zip
```

To install wheel files, you can run the following command:


$ pip install --use-wheel --no-index --find-links=./wheelhouse --requirement=./requirements.txt

To collect tests, you can run the following command:


$ py.test --collect-only tests

A valid Appium Python package should produce output like the following:


==================== test session starts ====================

To deactivate the virtual environment, you can run the following command:
```
$ deactivate

For more information, see Appium tests and AWS Device Farm.

APPIUM_PYTHON_TEST_PACKAGE_DEPENDENCY_WHEELS_INSUFFICIENT

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

Warning

We could not find enough wheel dependencies in the wheelhouse directory. Please unzip your test package, and then open the wheelhouse directory. Verify that you have all the wheel dependencies specified in the requirements.txt file.

Make sure that you can unzip the test package without errors. In the following example, the package's name is test_bundle.zip.

Copy your test package to your working directory, and then run the following command:
```
$ unzip test_bundle.zip
```
Check the length of the requirements.txt file as well as the number of .whl dependent files in the wheelhouse directory:
```
$ cat requirements.txt | egrep "." |wc -l
    12
$ ls wheelhouse/ | egrep ".+\.whl" | wc -l
    11
```
If the number of .whl dependent files is less than the number of non-empty rows in your requirements.txt file, then you need to ensure the following:
- There is a .whl dependent file corresponding to each row in the requirements.txt file.
- There are no other lines in the requirements.txt file that contain information other than the dependency package names.
- No dependency names are duplicated in multiple lines in the requirements.txt file such that two lines in the file may correspond to one .whl dependent file.
AWS Device Farm doesn't support lines in the requirements.txt file that don't directly correspond to dependency packages, such as lines that specify global options for the pip install command. See Requirements file format for a list of global options.
