Firefox上的Selenium Python Action链失败

标签: python selenium firefox selenium-webdriver webdriver

我使用以下库进行测试:

py==1.4.31 
pytest==2.8.5 
requests==2.9.1 
robotframework==2.8.5 
robotframework-selenium2library==1.5.0 
selenium==3.3.1

python 2.7

每当我尝试在Firefox上执行Action Chains命令时,我都会收到WebDriverException。该代码适用于Chrome和IE。我尝试了几种不同风格的Action Chain命令,但两者都失败了。

                ActionChains(self.driver).key_down(Keys.SHIFT).click(self.driver.find_element_by_xpath("//select[@name='ctstate']/option[@value='" + stateList[0] + "']")).click(self.driver.find_element_by_xpath("//select[@name='ctstate']/option[@value='" + stateList[1] + "']")).click(self.driver.find_element_by_xpath("//select[@name='ctstate']/option[@value='" + stateList[2] + "']")).key_up(Keys.SHIFT).perform()

......和......

                ActionChains(self.driver) \
                .key_down(Keys.SHIFT) \
                .click(self.driver.find_element_by_xpath("//select[@name='ctstate']/option[@value='" + stateList[0] + "']")) \
                .click(self.driver.find_element_by_xpath("//select[@name='ctstate']/option[@value='" + stateList[1] + "']")) \
                .click(self.driver.find_element_by_xpath("//select[@name='ctstate']/option[@value='" + stateList[2] + "']")) \
                .key_up(Keys.SHIFT) \
                .perform()

从命令中可以看出,我在屏幕上选择对象时按住shift键。然后我释放换档键。这是我收到的失败:

我非常难过为什么Firefox不喜欢我尝试使用任何Action Chain命令。任何建议或见解将不胜感激。

如果您的geckodriver版本为<v0.14,请将其升级为>=v0.15。这是早期版本的geckodriver中的一个已知问题,它不支持Actions类。 看到: SO answer
