[英]Selenium Edge driver not initializing when called from ant process - java
我试图在边缘运行一些硒测试，但我遇到了这个问题：
当我从Java环境（例如JDeveloper）运行它们时，一切正常。 但是，我们已经建立了一个蚂蚁程序来从命令行调用测试。 当我尝试执行此操作时，WebDriver尚未初始化，并引发异常错误。
我非常确定该错误不在ant文件中，因为如果我在chrome中运行相同的测试，则可以正常运行。
这是代码失败的一部分：
System.setProperty("webdriver.edge.driver","PathToFolder\\MicrosoftWebDriver.exe");
DesiredCapabilities capability = DesiredCapabilities.edge();
driver = new EdgeDriver(capability);
我确信问题不在路径上，因为当我直接从类中运行它时，它运行良好。 另外，我已经检查了内部版本号，并且我具有正确的MicrosoftWebDriver.exe，所以这也不是问题。
我得到的错误如下：
org.openqa.selenium.WebDriverException: Unknown error

更新 ：我能够恢复完整的日志，它是以下内容：

该错误确实给我们一些提示，如下所示：
java.lang.Error: org.openqa.selenium.WebDriverException: Unknown error
Command duration or timeout: 1.01 seconds

这本质上意味着EdgeDriver二进制文件根本没有被检测到 ，并且未经初始化会抛出未知错误 。
您的主要问题是所使用的二进制文件之间的版本兼容性 ，如下所示：
JDK Version 1.7.0_25 [ as per the error stack trace within your question ] Selenium Version 2.48.2 （于2015-10-09 19:55:52发布）[ as per the error stack trace within your question ] EdgeDriver （我们未知的版本） Edge Browser （我们未知的版本） 很明显 ：
JDK Version已过时。 EdgeDriver二进制文件。 JDK最近JDK 8u151水平。 Selenium升级到当前Version 3.8.1 。 EdgeDriver目前v5.16299水平。 Edge Browser升级到v16.16299支持级别。 IDE Clean并Re-Build项目。 Browser Cache CCleaner工具以清除所有操作系统琐事。 Edge Browser基本版本太旧，请通过带有Moderate Scan Revo Uninstaller卸载Web Browser并安装最新的GA Released Web Browser版本。 Test ：
