使用Java Selenium的Angular 4等待条件
使用Java Selenium的Angular 4等待条件
提问于 2017-09-17 04:01:23
我在为java selenium编写一个同时适用于Angular 4和Angular 1的等待条件时遇到了问题。我目前有一个适用于Angular 1的解决方案，如下所示：
public static ExpectedCondition<Boolean> angularHasFinishedProcessing() {
return new ExpectedCondition<Boolean>() {
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());
}
};
}
public static void waitOnAngular(WebDriver driver){
WebDriverWait wait = new WebDriverWait(driver, 15, 100);
wait.until(AdditionalConditions.angularHasFinishedProcessing());
}我正在寻找一些JavaScript来扩展这个apply()方法，以便与angular 4或其他解决方案一起工作，人们已经成功地让selenium等待angular $http请求与所有视图一起加载。
查看下面的pom.xml文件，了解我所使用的selenium-java的版本。

这是我之前在SO中发现的，并成功地使用它来等待angular。但我不知道它是否对两个都有效。
final String script = "var callback = arguments[arguments.length - 1];\n" +
"var rootSelector = \'body\';\n" +
"var el = document.querySelector(rootSelector);\n" +
"\n" +
"try {\n" +
" if (angular) {\n" +
" window.angular.getTestability(el).whenStable(callback);\n" +
" }\n" +
" else {\n" +
" callback();\n" +
" }\n" +
"} catch (err) {\n" +
" callback(err.message);\n" +
"}";
((JavascriptExecutor) getDriver()).executeAsyncScript(script, new Object[0]);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
