试图关闭webdriver时获取无效的会话id

Question

当我试图用下面的代码关闭浏览器时，我得到了一个无效的会话id，而我的测试失败了。当我注释掉browser.close()行时，这个错误就消失了。但是我想确保浏览器在我的测试完成后关闭，这样它就可以在RAM中留出一些空间。

在测试的最后，我调用这个注销脚本

var selenium = org.openqa.selenium
var support_ui=JavaImporter(org.openqa.selenium.support.ui) 
var EC = org.openqa.selenium.support.ui.ExpectedConditions

WDS.sampleResult.sampleStart()
-- some code
logout()
WDS.sampleResult.sampleEnd()

function logout(){
    var logoutBtn = waitByElement(selenium.By.cssSelector("button[title='User Options']"), EC.elementToBeClickable, 30)
    logoutBtn.click();
    WDS.browser.findElement(selenium.By.cssSelector("button[data-testid='logout']")).click();
    var userNameField = waitByElement(selenium.By.xpath("//*[contains(text(),'Disclaimer')]"), EC.presenceOfElementLocated, 60)
    takeScreenshot('screenshot_loggedout')
    WDS.browser.close()
}

控制台出错。

Answer 1

只要删除WDS.browser.close()语句，当线程结束时，WebDriver实例将自动关闭，不需要关闭/退出浏览器。
