我正在为基于角度的应用创建测试,我需要帮助。
我必须创建一个等待,直到所有待处理的请求都将被处理。
基本上在我的场景中我想标记一个复选框,但它仅在GET请求完成时可用,如果我使用简单Thread.sleep(2000)
一切正常,但我知道这不是解决此问题的可靠方法。
我尝试了两种方法:
首先:
AdditionalConditions wait = new AdditionalConditions();
wait.untilAngularFinishHttpCalls();
public void untilAngularFinishHttpCalls() {
final String javaScriptToLoadAngular =
"var injector = window.angular.element('app-root').injector();" +
"var $http = injector.get('$http');" +
"return ($http.pendingRequests.length === 0)";
ExpectedCondition<Boolean> pendingHttpCallsCondition = new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver driver) {
return ((JavascriptExecutor) driver).executeScript(javaScriptToLoadAngular).equals(true);
}
};
WebDriverWait wait = new WebDriverWait(SharedDriver.getDriver(), 20); // timeout = 20 secs
wait.until(pendingHttpCallsCondition);
}
在这里我得到以下错误:
org.openqa.selenium.WebDriverException:未知错误:无法读取 属性'element'未定义(会话信息:chrome = 59.0.3071.115)
(司机信息:chromedriver = 2.31.488763 (092de99f48a300323ecf8c2a4e2e7cab51de5ba8),platform = Windows NT 10.0.15063 x86_64)(警告:服务器未提供任何堆栈跟踪信息)命令持续时间或超时:5毫秒构建信息: 版本:'2.31.0',修订版: '1bd294d185a80fa4206dfeab80ba773c04ac33c0',时间:'2013-02-27 13:51:26'系统信息:os.name:'Windows 10',os.arch:'amd64', os.version:'10 .0',java.version:'1.8.0_121'驱动程序信息: org.openqa.selenium.chrome.ChromeDriver功能 [{applicationCacheEnabled = false,rotate = false, mobileEmulationEnabled = false,networkConnectionEnabled = false, 铬= {chromedriverVersion = 2.31.488763 (092de99f48a300323ecf8c2a4e2e7cab51de5ba8), userDataDir = C:\用户\ lpaczek \应用程序数据\本地\ TEMP \ scoped_dir13872_15975}, takesHeapSnapshot = true,pageLoadStrategy = normal, databaseEnabled = false,handlesAlerts = true,hasTouchScreen = false, version = 59.0.3071.115,platform = XP,browserConnectionEnabled = false, nativeEvents = true,acceptSslCerts = true,locationContextEnabled = true, webStorageEnabled = true,browserName = chrome,takesScreenshot = true, javascriptEnabled = true,cssSelectorsEnabled = true,setWindowRect = true, unexpectedAlertBehaviour =}]
我也试过了:
WebDriverWait wait = new WebDriverWait(SharedDriver.getDriver(), 15, 500);
wait.until(AdditionalConditions.angularHasFinishedProcessing());
public class AdditionalConditions {
public static ExpectedCondition<Boolean> angularHasFinishedProcessing() {
return new ExpectedCondition<Boolean>() {
@Override
public Boolean apply(WebDriver driver) {
return Boolean.valueOf(((JavascriptExecutor)
driver).executeScript("return (window.angular !== undefined) && (angular.element(document).injector() !== undefined) && (angular.element(document).injector(). get('$http').pendingRequests.length === 0)").toString());
}
};
}
在这里,我在15秒后得到超时。似乎它不起作用。 如果可以,请提供帮助,据我所知,我需要执行JavaScript代码并且我是新手。

你可以等待角度来完成它的工作
ngwebDriver包将为您提供该功能
var driver = new NgWebDriver(driver);
driver.waitForAngularRequestsToFinish();
