[英]How do I make AWS Device Farm run Appium tests with python 3.x?
我正在嘗試在 AWS Device Farm 上運行 python 3 中編寫的 Appium 測試。 如文檔中所述,
Python 2.7 在標准環境和使用自定義模式下均受支持。 當指定 Python 時,它是兩者的默認值。
Python 3 僅在自定義模式下受支持。 要選擇 Python 3 作為您的 python 版本,請更改測試規范以將 PYTHON_VERSION 設置為 3,如下所示:
phases:
install:
commands:
# ...
- export PYTHON_VERSION=3
- export APPIUM_VERSION=1.14.2
# Activate the Virtual Environment that Device Farm sets up for Python 3, then use Pip to install required packages.
- cd $DEVICEFARM_TEST_PACKAGE_PATH
- . bin/activate
- pip install -r requirements.txt
# ...
我過去確實在 Device Farm 上成功運行過測試,使用 python 3 自定義環境,使用這個規范文件(我只包括安裝階段):
phases:
install:
commands:
# Device Farm support two major versions of Python, each with one minor version: 2 (minor version 2.7), and 3 (minor version 3.7.4).
# The default Python version is 2, but you can switch to 3 by setting the following variable to 3:
- export PYTHON_VERSION=3
# This command will install your dependencies and verify that they're using the proper versions that you specified in your requirements.txt file. Because Device Farm preconfigures your environment within a
# Python Virtual Environment in its setup phase, you can use pip to install any Python packages just as you would locally.
- cd $DEVICEFARM_TEST_PACKAGE_PATH
- . bin/activate
- pip install -r requirements.txt
# ...
現在,當我運行測試時,我得到了這個日志,然后測試由於代碼不兼容而崩潰。

python 3.x 是否不再受支持,或者是否有未記錄的更改? 有沒有在 python 3 環境中運行測試的新方法?
記錄的方式仍然是正確的。
發現在虛擬環境下安裝pytest package 時出現錯誤。 這使得py.test
命令引用默認環境。
在我的例子中,通過安裝舊版本 pytest 並將其與其他軟件包捆綁在 requirements.txt 中解決了這個問題。
pip install pytest==6.2.4
