Javascript TypeError:无法读取属性';名字';未定义单元测试AngularJS的定义
我坚持用Karma做单元测试,我不知道如何做单元测试,因为这是我的第一次。我使用的是AngularJS,单元测试是Karma 事情是这样的:我使用服务获取客户的名字、姓氏和电话号码以显示在我的表单中,它可以正常工作,但当我尝试进行单元测试时,错误总是这样:Javascript TypeError:无法读取属性';名字';未定义单元测试AngularJS的定义,javascript,angularjs,unit-testing,karma-mocha,gulp-karma,Javascript,Angularjs,Unit Testing,Karma Mocha,Gulp Karma,我坚持用Karma做单元测试,我不知道如何做单元测试,因为这是我的第一次。我使用的是AngularJS,单元测试是Karma 事情是这样的:我使用服务获取客户的名字、姓氏和电话号码以显示在我的表单中,它可以正常工作,但当我尝试进行单元测试时,错误总是这样: directionFormulation component should load customer profile FAILED TypeError: Cannot read property 'firstName' of

directionFormulation.js
function directionFormulationController(event, customer, resolveLocation, order) {

您正在将
order
注入控制器,因此您需要为单元测试“模拟”出order
:
describe('addressForm component', function () {
var component;
var scope;
var order;
beforeEach(function () {
bard.appModule('shopping.address');
bard.inject('$rootScope', '$componentController', '$q', 'resolveLocation', 'customer', 'event','order');
order = {
customer: {
firstName: 'Joe',
lastName: 'Smith',
phoneNumber: '416-555-1234'
}
};
scope = $rootScope.$new();
component = $componentController('addressForm', {
$scope: scope,
order: order
});
});
it('should be attached to the scope', function () {
expect(scope.addressForm).to.be.equal(component);
});
it('should load customer profile', function () {
component.$onInit();
component.loadCustomerProfile();
expect(component.input.firstName).to.be.equal(order.customer.firstName);
expect(component.input.lastName).to.be.equal(order.customer.lastName);
expect(component.input.phoneNumber).to.be.equal(order.customer.phoneNumber);
});
});
我想强调几个其他问题:
expect(scope.addressForm).to.be.equal(组件)代码>不会通过AddressFormController
是控制器的名称,控制器是组件的属性
bard
在您的测试中指的是什么,也不确定appModule
是否是您的bard实例上的属性。以下是我的组件测试设置示例:您正在将
