下面是一个带有AngularJS ng-click属性的div,该属性在单击该div时设置一个变量。
<div id="id"
ng-click="foo.bar = true;">
Set bar variable on foo object to true
</div>
下面是一些使用Selenium单击div元素的Java代码。
By upload = By.id("id");
driver.findElement(uploadCensus).click();
当我运行Java代码时,AngularJS永远挂起。我认为foo.bar不是在单击div时设置的,所以这里有一些直接设置变量的代码。
By upload = By.id("id");
((JavascriptExecutor) driver)
.executeScript("foo.bar = true;",
driver.findElement(upload));

当我尝试设置foo.bar
时,我无法获得对该变量的引用,因为它不是全局定义的,并且隐藏在AngularJS源代码中的某个地方。我试图解开索引并查找变量,但似乎找不到它。我想通过JavascriptExecutor
手动设置foo.bar
变量,但无法获得对该变量的引用。如何查找和设置变量?
如果这看起来是触发ng-click
的错误方式,我对此持开放态度。我相信Protractor有办法解决这个问题,但这个AngularJS应用程序部署在企业环境中,几个月来一直试图让业务部门批准这项技术。我被硒困住了。救命..。

只需直接回答您的问题,不要将其用于您的案例:)
Angular有隔离变量scope.So,你需要得到作用域,并在其中设置变量。
angular.element("#id").scope().foo.bar = true;
但不要把它用在你的情况下。当您在系统级别测试应用程序时,您必须以与用户相同的方式测试它们。
推荐答案:等待java中的角度可测试性
好消息是你可以在expilcit wait中使用JavaScriptExecutor来执行相同类型的javascript。
您的java代码,用于为waitforangular创建预期的condrion
String waitForAngularJs ="Your javascript goes here"; // as it is lengthy read it from file and store here.
ExpectedCondition<Boolean> waitForAngular= new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver driver) {
return ((JavascriptExecutor) driver).executeAsyncScript(waitForAngularJs).equals(true);
}
};
WebDriverWait wait = new WebDriverWait(driver, 60);
wait.until(waitForAngular);
等待angular Javascript (为您的Java执行而修改。但我没有检查):
我将回调设置为一个简单的函数,返回true,并与根定位器[ng-app]
挂钩。
var testCallback = function() {
return true;
};
// Wait for angular1 testability first and run waitForAngular2 as a callback
var waitForAngular1 = function(callback) {
if (window.angular) {
var hooks = window.angular.element('[ng-app]');
if (!hooks){
callback(); // not an angular1 app
}
else{
if (hooks.$$testability) {
hooks.$$testability.whenStable(callback);
} else if (hooks.$injector) {
hooks.$injector.get('$browser')
.notifyWhenNoOutstandingRequests(callback);
} else if (!rootSelector) {
throw new Error(
'Could not automatically find injector on page: "' +
window.location.toString() + '". Consider using config.rootEl');
} else {
throw new Error(
'root element (' + rootSelector + ') has no injector.' +
' this may mean it is not inside ng-app.');
}
}
}
else {callback();} // not an angular1 app
};
// Wait for Angular2 testability and then run test callback
var waitForAngular2 = function() {
if (window.getAngularTestability) {
if (rootSelector) {
var testability = null;
var el = document.querySelector(rootSelector);
try{
testability = window.getAngularTestability(el);
}
catch(e){}
if (testability) {
testability.whenStable(testCallback);
return;
}
}
// Didn't specify root element or testability could not be found
// by rootSelector. This may happen in a hybrid app, which could have
// more than one root.
var testabilities = window.getAllAngularTestabilities();
var count = testabilities.length;
// No angular2 testability, this happens when
// going to a hybrid page and going back to a pure angular1 page
if (count === 0) {
testCallback();
return;
}
var decrement = function() {
count--;
if (count === 0) {
testCallback();
}
};
testabilities.forEach(function(testability) {
testability.whenStable(decrement);
});
}
else {testCallback();} // not an angular2 app
};
if (!(window.angular) && !(window.getAngularTestability)) {
// no testability hook
throw new Error(
'both angularJS testability and angular testability are undefined.' +
' This could be either ' +
'because this is a non-angular page or because your test involves ' +
'client-side navigation, which can interfere with Protractor\'s ' +
'bootstrapping. See http://git.io/v4gXM for details');
} else {waitForAngular1(waitForAngular2);} // Wait for angular1 and angular2
// Testability hooks sequentially
为什么我们需要这个,因为angular使用了html模板,双向数据绑定,ajax请求和路由。因此,在页面导航之后,我们必须等待所有这些操作(requests & promises)完成。否则,html将不会像您所期望的那样响应。
检查角度可测试性
要基于元素进行检查,
window.getAngularTestability(el).whenStable(callback); //Here el is element to be valiated.
要检查所有可测试性,
window.getAllAngularTestabilities();
testabilities.forEach(function(testability) {
testability.whenStable(callback);
});
在检查角度可测试性之前,我们可以确保没有以下行的http请求挂起。
angular.element(document).injector().get('$http').pendingRequest.length
