本文介绍了为什么我的IE浏览器与Selenium和Cucumber一起启动了两次?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在用Selenium-Cucumber编写非常基本的自动化测试，该测试将启动IE浏览器并最终关闭它.
I am writing very basic automation test with Selenium-Cucumber that is launching an IE browser and closing it at the end.
问题是浏览器启动了两次.
The problem is that the browser gets launched twice.
除少数System.out语句外，该测试没有太多其他内容.对于基于selenium的自动化测试和Cucumber，我都是新手，却无法理解为什么它要两次启动.
The test does not have much it other than few System.out statements. I am kind of new to both selenium-based automation testing and Cucumber and not able to understand why is it getting launched twice.
请指导.

推荐答案
因为您正在初始化，因此在功能文件中两次调用了驱动程序.
Because you are initializing and call your driver twice in feature files.
Background部分首先在LoginStep.java中初始化浏览器，然后您的Scenario在HelpStep.java中也初始化浏览器.
Background part of your feature file are initializing browser firstly in LoginStep.java then your Scenario is also initialize browser in HelpStep.java.
我更喜欢对@Before和@After挂钩使用全局Hooks.java类，并在不同的.java类之间插入驱动程序.
I prefer using global Hooks.java class for @Before and @After hooks and inject driver between different .java classes.
