[英]Testing UI router states with $stateChangeStart and $rootScope
如何使用$ stateChangeStart或其他發出的事件進行測試?
我有以下代碼,從本質上講,該代碼檢查用戶是否已登錄,如果未登錄,則重定向到app.login
狀態
app.run(function ($rootScope, $state, AuthenticationService) {
$rootScope.AuthenticationService = AuthenticationService
$rootScope.isLoggedIn = AuthenticationService.getIsLoggedIn
if (!$rootScope.isLoggedIn()) {
$state.go('app.login')
}
// Catch all errors on state change
$rootScope.$on('$stateChangeError', function (event, toState, toParams, fromState, fromParams, error) {
$state.go('app.home')
})
// Sets up the role requirements per state
$rootScope.$on('$stateChangeStart', function (event, toState) {
if (AuthenticationService.getIsLoggedIn()) {
} else {
if (toState && toState.name !== 'app.login') {
$state.go('app.login')
}
}
})
})
我正在嘗試達到的測試:
'use strict'
describe('Controller', function () {
var $scope
, $state
, $rootScope
, AuthenticationService
, $controller
beforeEach(module('replanApp'))
beforeEach(inject(function ($injector) {
$state = $injector.get('$state')
$rootScope = $injector.get('$rootScope')
AuthenticationService = $injector.get('AuthenticationService')
$scope = $rootScope.$new()
$controller = $injector.get('$controller')
}))
describe('Initializers', function () {
it('should redirect to /login if the user is not logged in', function () {
$state.go('app.admin.index')
$rootScope.$apply()
assert.notOk(AuthenticationService.getIsLoggedIn())
assert.equal($state.current.name, 'app.login')
})
})
})
它基本上應該進入一個狀態,然后$rootScope.$on('$stateChangeStart', fn(){})
應該已經看到用戶尚未登錄,並將其轉移到app.login
狀態。
但我收到AssertionError: expected 'app.admin.index' to equal 'app.login'
如何使用$ stateChangeStart和其他事件來完成測試?
我將修改測試以檢查是否已使用'app.login'
調用了$state.go
,而不是嘗試檢查當前狀態是什么:
describe('Initializers', function () {
beforeEach(function(){
spyOn($state,'go');
});
it('should redirect to /login if the user is not logged in', function () {
$state.transitionTo('app.admin.index');
$rootScope.$apply();
assert.notOk(AuthenticationService.getIsLoggedIn());
expect($state.go).toHaveBeenCalledWith('app.login');
});
});
我不能保證會修復您的測試,但是它將使它更像一個單元測試,因為它不會依賴$state.go
來設置當前狀態。
