我的任务是为另一个团队编写的一些 AngularJS 代码编写单元测试,但他们没有编写任何测试
他们编写了以下函数,但我不知道如何测试它
function showCallAlerts(callRecord, isInEditMode, callBack) {
var callAlerts = populateCallAlertOnEditCall(callRecord.callAlert);
var callModalInstance = openAlertModalInstance('Call', callAlerts, callBack);
if (callModalInstance !== undefined && callModalInstance !== null) {
callModalInstance.result.then(function() {
// Show equipment alerts based on company details
showEquipmentAlertsBasedOnCompanyDetails(callRecord, isInEditMode, callBack);
});
} else {
// Show equipment alerts based on company details
showEquipmentAlertsBasedOnCompanyDetails(callRecord, isInEditMode, callBack);
}
}
我需要测试每个函数是否被调用,而不用担心它们的作用,因为我将单独测试它们,只关心它们被调用。
当调用 populateCallAlertOnEditCall 时,它需要返回一个空数组或一个包含某些项目的数组
当调用 openAlertModalInstance 时,它需要返回 undefined 或传递给 showEquipmentAlertsBasedOnCompanyDetails 的内容
showEquipmentAlertsBasedOnCompanyDetails 实际上应该被调用,我将单独测试该方法,只是它被调用了
我已经设法编写代码来测试简单的功能,但没有像这样的代码,所以任何帮助将不胜感激,我今天下午的大部分时间都在试图弄清楚
最佳答案
您可以使用 jasmine 来模拟您不感兴趣测试的函数调用。例如,您可以告诉 jasmine 每次调用“populateCallAlertOnEditCall”时返回一个空数组。我将写一个示例,可能会让您有所了解:
describe('My Test Spec', function() {
var myController;
...
beforeEach( inject(($controller) => {
myController = $controller("myControllerName");
}));
it('Testing showCallAlerts when populateCallAlertOnEditCall returns an empty array', inject(function($controller) {
//setup
//this will replace every call to populateCallAlertOnEditCall with
//the function inside callFake
spyOn(myController, 'populateCallAlertOnEditCall ').and.callFake(function() {
return []; //returning an empty array.
});
//action
myController.showCallAlerts(...);
//assert
//Do your checking here.
}));
it('Testing showCallAlerts when populateCallAlertOnEditCall returns a non-empty array', inject(function($controller) {
//setup
//this will replace every call to populateCallAlertOnEditCall with
//the function inside callFake
spyOn(myController, 'populateCallAlertOnEditCall ').and.callFake(function() {
return [1,2,3,4]; //returning a non-empty array.
});
//action
myController.showCallAlerts(...);
//assert
//Do your checking here.
}));
});
