我正在使用Java Gradle,Selenium 3.8.0和IEWebDriver 3.8.0。
Chrome和Firefox工作正常,但IE会抛出org.openqa.selenium.TimeoutException: Expected condition failed
异常,但如果我逐步调试源代码,IE也能正常工作。
因此,我花了很长时间才发现这个问题,并且我注意到IE在调用webDriver.get(..)
时会丢失WebDriver和源代码之间的连接,这看起来像是这样:
driver.get(url);
waitForPageLoaded(driver);
因此我认为存在一些时间问题,但我已经尝试过处理这个问题:
public void waitForPageLoaded(WebDriver driver) {
logger.debug("Wait until the page was loaded.");
// IE seems to fail here.
new WebDriverWait(driver, SeleniumConfigurator.TIME_OUT)
.until(d -> ((JavascriptExecutor)d).executeScript("return document.readyState")
.equals("complete"));
}
然后我注意到IE需要更多配置设置,但我不允许设置其中一些:IT限制 - >我无法更改注册表项。
但是,为什么它在调试时工作正常?
这是我的IE设置:
case IE:
path = "../../../../../../resources/driver/win/IEDriverServer_32_v3-8-0.exe";
url = getClass().getResource(path);
if (url == null) {
logger.error("Could not find the Internet Explorer web driver binary at " + path + " ." +
"All test for this browser will be ignored.");
currentBrowserType = BrowserType.UNDEFINED;
break;
}
try {
System.setProperty("webdriver.ie.driver", Paths.get(url.toURI()).toFile().getAbsolutePath());
} catch (URISyntaxException e) {
e.printStackTrace();
}
// https://sqa.stackexchange.com/questions/13077/unable-to-run-selenium-webdriver-script-in-ie11
InternetExplorerOptions optionsIE = new InternetExplorerOptions();
optionsIE.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);
optionsIE.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true);
optionsIE.withAttachTimeout(SeleniumConfigurator.TIME_OUT, TimeUnit.SECONDS);
//optionsIE.setCapability(InternetExplorerDriver.REQUIRE_WINDOW_FOCUS, true);
webDriver = new InternetExplorerDriver(optionsIE);
currentBrowserType = BrowserType.IE;
break;
我不知道这里出了什么问题..
第一个测试工作正常,之后出现超时异常(看看评论):
@Test
public void test_Contact() {
Init();
util.logTestStart("Test contact on index page..");
String xPath = "//*[@id='contact-link']/a";
WebElement element = webDriver.findElement(By.xpath(xPath));
Assert.assertEquals(element.getAttribute("href"), "mailto:what@ever.com");
}
@Test
public void test_LegalInformation() {
Init();
util.logTestStart("Test legal information on index page..");
String xPath = "//*[@id='link-highlighted']/a";
util.aTagClickByXPath(webDriver, xPath);
Assert.assertEquals(webDriver.getCurrentUrl(), "http://whatever.com/");
}
private void Init() {
if (configurator == null) {
configurator = SeleniumConfigurator.getInstance();
}
if (webDriver != configurator.getWebDriver()) {
webDriver = configurator.getWebDriver();
}
if (util == null) {
util = new SeleniumTestUtil();
}
// Open localhost as default
util.goTo(webDriver, "http://localhost:8080/de/index");
}
public void aTagClickByXPath(WebDriver driver, String xPath) {
logger.debug("Performing a click on an a-Tag, xPath: " + xPath);
WebElement element = driver.findElement(By.xpath(xPath));
element.click(); // First click works, second one fails, cause of Timeout Exception
waitForPageLoaded(driver);
}
有人有提示吗?
修改
org.openqa.selenium.NoSuchWindowException: Unable to get browser
现在被抛出。超时异常不再出现了。我一无所获。

超时定义:
public static final int TIME_OUT = 15;
答案 0 :(得分:2)
您可能需要考虑以下几个事实:
function()
public void waitForPageLoaded(WebDriver driver)
看起来像纯粹的开销。基本上不需要在 WebDriverWait
根据 WebDriverWait
中 Selenium v3.8.1
的当前实施情况,构造函数如下:
WebDriverWait(WebDriver driver, Clock clock, Sleeper sleeper, long timeOutInSeconds, long sleepTimeOut)
WebDriverWait(WebDriver driver, long timeOutInSeconds)
WebDriverWait(WebDriver driver, long timeOutInSeconds, long sleepInMillis)
目前还不清楚如何实施 WebDriverWait(driver, SeleniumConfigurator.TIME_OUT)
。这些参数看起来容易出错。
同样,直到条件 d -> ((JavascriptExecutor)d).executeScript("return document.readyState").equals("complete")
是开销,因为Client
(即Web Browser
)永远不会将控件返回到{{1实例直到和除非'document.readyState'等于“完成”。一旦满足此条件,WebDriver
将执行下一行代码。因此, Selenium
的此功能没有任何影响。
值得一提的是,虽然Boolean org.openqa.selenium.support.ui.FluentWait.until(Function<? super WebDriver, Boolean> arg0)
(即Client
)可以将控件返回到Web Browser
实例一次'document.readyState'等于“完成“已经实现,新 WebDriver
上的所有WebElements
HTML DOM
并不是一成不变的, VISIBLE
和 INTERACTABLE
。
CLICKABLE
,以确保调用 xPath = "//*[@id='link-highlighted']/a"
是否会打开新标签页或网址被重定向。我没有看到你处理任何一种情况。click()
时,请注意 InternetExplorer
在真实浏览器中运行并支持Javascript。通过以下方式设置浏览器焦点:
InternetExplorerDriver
如果 capabilities.setCapability("requireWindowFocus", true);
打开一个新窗口,切换 window_handles
