Question

我正在尝试Python 2.7项目而不熟悉Python。没有安装Firefox时有一个测试失败，因为它使用的是使用Firefox的selenium。我希望测试在无法运行时自动跳过。

测试课

class SeleniumAuthTestCase(SeleniumTestCase):

我得到的错误

Traceback (most recent call last):
  File "/mnt/vagrant/source/some/path/tests/selenium/test_auth.py", line 14, in setUpClass
    super(cls, cls).setUpClass()
  File "/mnt/vagrant/source/some/path/testcases.py", line 14, in setUpClass
    cls.driver = Firefox()
  File "/some/path/venv/local/lib/python2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 55, in __init__
    self.binary = firefox_binary or capabilities.get("binary", FirefoxBinary())
  File "/some/path/venv/local/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 47, in __init__
    self._start_cmd = self._get_firefox_start_cmd()
  File "/some/path/venv/local/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 163, in _get_firefox_start_cmd
    " Please specify the firefox binary location or install firefox")
RuntimeError: Could not find firefox in your system PATH. Please specify the firefox binary location or install firefox

我发现有一种方法可以individual test methods skipped via annotation。但是，此错误发生在调用任何测试方法之前：在父类的setUpClass中。

我也想通了我可以重载方法：

@classmethod
def setUpClass(cls):
    super(SeleniumAuthTestCase, cls).setUpClass()

所以我可以检查是否加载了依赖项，如果不加载，则避免调用父类。最重要的是，我可以设置一些标志来指示是否加载了东西，然后为每个检查它的方法都有一个注释。这非常笨拙，我更喜欢做这样的PHPUnit代码：

public function setUp() {
    if ( true ) {
        $this->markTestSkipped();
    }
}

这通常是如何在Python中完成的？

approach that sbarzowski linked为我工作。

@classmethod
def setUpClass(cls):
    try:
        Firefox()
    except:
        raise unittest.SkipTest("Selenium webdriver needs Firefox, which is not available")

    super(SeleniumAuthTestCase, cls).setUpClass()

当依赖性不可用时跳过Python测试
