如何为Rectangular编写茉莉花测试,如下所示
脚本
$scope.allEmployees = [{
visible: true,
empId: "EMP148"
}];
$scope.employeeDocuments = { "EMP148": [{
"empId": "EMP148",
"department": "Sales",
"firstName": "Manu",
"lastName": "Mathew",
"place": "Kolkata"
}]
};
var employeesCopy = angular.copy($scope.allEmployees);
$scope.allEmployees.push({visible: true, empId: "EMP489"});
$scope.addEmployees = function (employeesCopy) {
var newEmployee = {visible: true, empId: "EMP489"};
var emplyeeList = {
employees: $scope.allEmployees,
newEmployee: newEmployee
};
Restangular.all('emp/getEmployees').post(emplyeeList).then(function (employees) {
if (!_.isEmpty(employees[emplyeeList.newEmployee.empId])) {
if ($scope.employeeDocuments.hasOwnProperty(emplyeeList.newEmployee.empId)) {
delete $scope.employeeDocuments[emplyeeList.newEmployee.empId];
}
$scope.employeeDocuments[emplyeeList.newEmployee.empId] = employees[emplyeeList.newEmployee.empId];
setMyEmployees(true);
$scope.flag = true;
console.log("success");
} else {
$scope.employeeDocuments = employeesCopy;
console.log("no documents");
}
$scope.flag = false;
}, function (error) {
console.log("failed");
$scope.flag = false;
});
};
$scope.addEmployees(employeesCopy);
setMyEmployees = function (flag)
{
// other implementation
};
我写了一个如下所示的测试用例,但是我得到了异常,就像spyOn找不到一个对象来监视所有()
测试用例
WORKING DEMO – 包含完整的逻辑和测试用例
describe('Testing Controllers', function() {
describe('Testing EmployeeController Controller', function() {
var EmployeeController, $scope, $httpBackend, Restangular;
beforeEach(function() {
module('emp');
});
beforeEach(inject(function($controller, $rootScope, $filter, $injector, Restangular, $httpBackend) {
$scope = $rootScope.$new();
$httpBackend = $httpBackend;
Restangular = $injector.get("Restangular");
EmployeeController = $controller('EmployeeController ', {
$rootScope: $rootScope,
$scope: $scope,
$filter: $filter
});
}));
it('should add new employees when addEmployees() is called', inject(function($httpBackend)
{
$scope.allEmployees = [{
visible: true,
empId: "EMP148"
}];
$scope.employeeDocuments = { "EMP148": [{
"empId": "EMP148",
"department": "Sales",
"firstName": "Manu",
"lastName": "Mathew",
"place": "Kolkata"
}]
};
var employeesCopy = angular.copy($scope.allEmployees);
spyOn(Restangular, 'all').andCallThrough();
var newEmployee = {visible: true, empId: "EMP489"};
var emplyeeList = {
employees: $scope.allEmployees,
newEmployee: newEmployee
};
var mockToReturn = {
"EMP489": [{
"empId": "EMP489",
"department": "Sales",
"firstName": "Ram",
"lastName": "Mohan",
"place": "Delhi"
}]
};
$scope.addEmployees(employeesCopy);
$httpBackend.expectPOST('emp/getEmployees',emplyeeList).respond(mockToReturn);
expect(Restangular.all).toHaveBeenCalledWith('emp/getEmployees');
expect(setMyEmployees(true)).toHaveBeenCalled();
}));
});
});
解决方法:
你有多个问题：
首先,要回答你的问题,请使用toHavebeenCalled,你必须先创建一个间谍.
我要做的是将setMyEmployees放在作用域级别,然后在作用域上添加一个间谍
spyOn($scope);
但是您有一个测试会产生异步请求,因此您的测试用例将失败,因为它将在异步请求成功之前到达终点.
使用jasmine 2,您可以使用done()进行异步测试：
it('should add new employees when addEmployees() is called', function(done)
{
//call when asyncronous operation is finish
done();
}
但是按照你创建函数的方式,你不能使用done.
您必须在方法或承诺中有一个回调块
打回来 ：
$scope.addEmployees = function(employeesCopy, success, failure)
{
//code
Restangular.all('user/getEmployees').post(emplyeeList).then(function(employees)
{
if (!_.isEmpty(employees[emplyeeList.employeeId]))
{
// code
}
else
{
// code
}
success();
$scope.flag = false;
}, function(error)
{
failure();
$scope.flag = false;
});
};
请注意toHaveBeenCall语法
it('should add new employees when addEmployees() is called', function(done)
{
var employeesCopy = {
firstName: "Manu",
lastName: "Sam"
};
spyOn($scope);
$scope.addEmployees(employeesCopy, function(){
done();
});
expect($scope.setMyEmployees).toHaveBeenCalledWith(true);
});
我更喜欢promise语法：
$scope.addEmployees = function(employeesCopy, defer)
{
//code
Restangular.all('user/getEmployees').post(emplyeeList).then(function(employees)
{
if (!_.isEmpty(employees[emplyeeList.employeeId]))
{
// code
}
else
{
// code
}
defer.resolve();
$scope.flag = false;
}, function(error)
{
defer.reject();
$scope.flag = false;
});
};
it('should add new employees when addEmployees() is called', function(done)
{
var employeesCopy = {
firstName: "Manu",
lastName: "Sam"
};
spyOn($scope);
var defer = $q.defer;
defer.promise.then(function(){
console.log("success");
done();
}, function (){
done();
console.log("error");
});
$scope.addEmployees(employeesCopy, defer);
expect($scope.setMyEmployees).toHaveBeenCalledWith(true);
});
如果你想让你的测试真正统一,那么你将遇到的最后一个问题就是模拟网络调用(否则你也会测试后端的答案,这可能是你想要的)
如果你想模拟电话,你应该看看$httpBackend,这篇博文似乎有更多的信息：https://ath3nd.wordpress.com/2013/08/05/15/(不是我的)
编辑,在你的it()之前添加依赖性测试,使用beforeEach：
var myService, Restangular;
beforeEach(function() {
inject(function($injector) {
myService = $injector.get('MyService');//exemple service
Restangular = $injector.get("Restangular");
});
});
编辑2：
好吧,我没有正确解释,尝试：
beforeEach(inject(function($controller, $rootScope, $filter, $injector, _Restangular_, _$httpBackend_) {
$scope = $rootScope.$new();
$httpBackend = _$httpBackend_;
Restangular = _Restangular_;
EmployeeController = $controller('EmployeeController ', {
$rootScope: $rootScope,
$scope: $scope,
$filter: $filter
});
}));
