我已经删除了应用程序，所以只有重要的事情在这里。我创建了一个名为databaseSrvc的服务，并尝试注入Jasmine单元测试。我已经检查了很多次，看它是否是拼写错误，如error page suggests，所以我很确定它不是。

angular.module("firebaseTestApp", [])
angular.module("firebaseTestApp")
.factory("databaseSrvc", function($firebaseObject) {
var databaseSrvc = {};
databaseSrvc.ref = firebase.database.ref();
databaseSrvc.echo = function(text) {

username: username,

});
}
databaseSrvc.removeUser = function(uid, username, email) {
databaseSrvc.ref.child("users").child("uid").removeValue();
}
databaseSrvc.usernameExists = function(username) {
query = databaseSrvc.ref.child("user").orderByChild("username").equalTo(username);
obj = $firebaseObject(query);
return obj.$loaded().then(function() {
if (obj.$value === null) {
return false;
} else {
return true;
}
});
}
return databaseSrvc;
});
评论的部分和后面的部分都不起作用。它总是记录“未定义”，并给出了上面提到的错误。
describe('databaseSrvc', function() {
beforeEach(module('firebaseTestApp'));
// var databaseSrvc;
// beforeEach(inject(function(_databaseSrvc_) {
// databaseSrvc = _databaseSrvc_;
// }));
//
//
// it('should exist', function() {
// console.log(databaseSrvc);
// expect(databaseSrvc).toBeTruthy();
// });
it('should exist', inject(function(databaseSrvc) {
console.log(databaseSrvc);
expect(databaseSrvc).toBeTruthy();
}));
});

describe('databaseSrvc', function() {
beforeEach(module('firebaseTestApp'))
// declaring in outer scope, will be reassigned below
var databaseSrvc = {}
var mockFirebaseObject = function() {
// this looks like the mock you need based on your service code
return {
$loaded: function() {
return {
then: function(cb) { cb() }
}
}
}
}
// provide your mock object as the $firebaseObject
beforeEach(module(function($provide) {
$provide.value('$firebaseObject', mockFirebaseObject)
}))
// inject the real databaseSrvc factory and reassign it
// to the variable in your outer scope, so that you can
// use it in the rest of the specs
beforeEach(inject(function(_databaseSrvc_) {
databaseSrvc = _databaseSrvc_
}))
describe('expectation', function() {
it('should do something', function() {
expect(databaseSrvc)....
})
})
})
您需要在期望可以访问的范围内公开注入的服务。
