Question

由于Selenium库中存在Javascript错误，我的测试有时会失败：

Exception traceback: Traceback (most recent call last):
    File "run.py", line 292, in <module>
        r.play()
    File "run.py", line 256, in play
        self.run_downloads()
    File "run.py", line 146, in run_downloads
        self.run_download(download)
    File "run.py", line 167, in run_download
        executor.start()
    File "run.py", line 61, in start
        expected_conditions.presence_of_element_located((By.CLASS_NAME, "newsfeed-widget"))
    File "/srv/intex/venv/local/lib/python2.7/site-packages/selenium/webdriver/support/wait.py", line 66, in until
        value = method(self._driver)
    File "/srv/intex/venv/local/lib/python2.7/site-packages/selenium/webdriver/support/expected_conditions.py", line 58, in __call__
        return _find_element(driver, self.locator)
    File "/srv/intex/venv/local/lib/python2.7/site-packages/selenium/webdriver/support/expected_conditions.py", line 279, in _find_element
        raise e
WebDriverException: Message: [JavaScript Error: "h is null" {file: "file:///tmp/tmpv9LZnL/extensions/fxdriver@googlecode.com/components/command-processor.js" line: 8478}]'[JavaScript Error: "h is null" {file: "file:///tmp/tmpv9LZnL/extensions/fxdriver@googlecode.com/components/command-processor.js" line: 8478}]' when calling method: [nsICommandProcessor::execute]

测试有时会成功执行，但似乎是随机的失败。

我正在使用Firefox WebDriver。

导致异常的代码是：

self.driver.find_element_by_name("button1").click()
try:
    WebDriverWait(self.driver, 60).until(
        expected_conditions.presence_of_element_located((By.CLASS_NAME, "newsfeed-widget")) #  This line throws the exception
    )
except TimeoutException:
    pass

有没有人对可能导致此问题的原因或如何调试此错误有任何想法？

由于

执行Selenium测试时，“h为空”
