javascript - 错误: [$injector:unpr] Unknown provider: a

Question

这是我的代码:

app.factory('assignmentAttachments', function() {


});

describe("test", function() {
    // arrange variable
    var assignmentAttachments;

    // inject service
     beforeEach(inject(function(_assignmentAttachments_) {
        assignmentAttachments = _assignmentAttachments_;
     })); 

    describe("test", function() {
        it("test", function() {
            // arrange

        })
    });

});

我收到以下错误:

Error: [$injector:unpr] Unknown provider: assignmentAttachmentsProvider <- assignmentAttachments http://errors.angularjs.org/1.2.27/$injector/unpr?p0=assignmentAttachmentsProvider%20%3C-%20assignmentAttachments

确保您已导入注册了 assignmentAttachments 的模块。例如，如果 assignmentAttachments 已在 app 模块中注册，如下所示:

var app = angular.module('app', [])
app.factory('assignmentAttachments', ...});

然后您必须在测试中导入该模块:

describe("test", function() {
    ...

    beforeEach(module('app')); // <== add this line

    // inject service
    beforeEach(inject(function(_assignmentAttachments_) {
        assignmentAttachments = _assignmentAttachments_;
    })); 
});
