运行 CI 使用 PyQT 进行测试

Question

我正在为我的团队设置 CI Bitbucket 管道。我们正在使用 pytest 和 pytest-qt 来测试我们的软件。本地测试运行没有任何问题，但使用管道构建失败。这是管道 yml：

image: python:3.9

pipelines:
  default:
    - parallel:
      - step:
          name: Test
          caches:
            - pip
          script:
            - if [ -f requirements.txt ]; then pip install -r requirements.txt; fi
            - pip install pytest
            - pip install pytest-qt
            - pytest -v tools/IntegrationTests.py --junitxml=test-reports/report.xml

文件 requirements.txt 包含几个模块，包括：

PyQt5==5.15.4
PyQt5-Qt5==5.15.2

这是尝试构建时的输出：

+ pytest -v tools/IntegrationTests.py --junitxml=test-reports/report.xml

INTERNALERROR> ImportError: libGL.so.1: cannot open shared object file: No such file or directory

我从中得到的是 Qt 没有正确远程安装，因此测试无法运行。

我的问题是：可以在 CI 中测试 GUI，如果可以，如何测试？

编辑：

我只测试了 PyQt 的导入，它归结为这个测试套件：

def test_import_widgets():
    from PyQt5 import QtWidgets


def test_import_core():
    from PyQt5 import QtCore


def test_import_gui():
    from PyQt5 import QtGui


def test_import_qt():
    from PyQt5.QtCore import Qt

这导致了以下结果：

2 / 4 tests failed
BasicsTests.test_import_guitools
<1s
ImportError: libGL.so.1: cannot open shared object file: No such file or directory
def test_import_gui():
>       from PyQt5 import QtGui

您必须安装 Qt 依赖项：

image: python:3.9

pipelines:
  default:
    - parallel:
      - step:
          name: Test
          caches:
            - pip
          script:
            - apt-get update && apt-get autoclean
            - apt-get install -y '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev
            - if [ -f requirements.txt ]; then pip install -r requirements.txt; fi
            - pip install pytest
            - pip install pytest-qt
            - pytest -v tools/IntegrationTests.py --junitxml=test-reports/report.xml
