如何用c#中的Selenium在Saucelabs测试中将图像上传到网页?

使用 LocalFileDetector 班您的代码将如下所示:

// WARNING!! Untested code written from memory, without benefit of an IDE.
// May not work exactly correctly or even compile without modification. 
// Assume driver is a properly instantiated IWebDriver object, which is
// to be used with a remote service (including SauceLabs or similar).
IAllowsFileDetection fileDetectionDriver = driver as IAllowsFileDetection;
fileDetectionDriver.FileDetector = new LocalFileDetector();

IWebElement fileElement = driver.FindElement(By.Id("idOfFileInputElement"));
fileElement.SendKeys(@"C:\path\to\local.file");

通过设置文件检测器 SendKeys 方法将首先将文件从本地系统上载到代码实际运行的远程计算机。然后 发送密钥 将在 <input> 元素,使用远程计算机上的本地文件路径。
