先决条件:我正在使用Karma对我的Angular.js应用模块运行Jasmine单元测试。
我的应用程序使用以下模式公开模块(服务/指令/控制器):
simple.js
'use strict';
export default (angular) => {
angular.module('simple', [])
.directive('simple', [function() {
return {
restrict: 'E',
replace: true,
template: '<h1>COMPILED!</h1>'
};
}]);
};
以上示例的相应单元测试如下所示:
simple.test.js
import angular from 'angular';
import mocks from 'angular-mocks';
import simpleModule from './simple';
describe('simple', () => {
var $compile,
$rootScope;
// Load the simple module, which contains the directive
beforeEach(() => {
let simpleComponent = new simpleModule(angular);
// module('simple') raises a TypeError here
// I have also tried angular.module('simple') which
// I am pretty sure is incorrect.
});
// Store references to $rootScope and $compile
// so they are available to all tests in this describe block
beforeEach(inject((_$compile_, _$rootScope_) => {
// The injector unwraps the underscores (_) from around the
// parameter names when matching
$compile = _$compile_;
$rootScope = _$rootScope_;
}));
it('Replaces the element with the appropriate content', () => {
// Compile a piece of HTML containing the directive
var element = angular.element("<simple>not compiled</simple>");
var compiledElement = $compile(element)($rootScope);
// fire all the watches, so the scope expressions evaluate
$rootScope.$digest();
// Check that the compiled element contains the templated content
expect(element.html()).toContain("COMPILED!");
});
});
问题:在网络浏览器中使用Karma运行上述测试时,测试失败并且元素似乎没有被编译。
我错过了什么?
答案 0 :(得分:2)
我可以在您的代码中看到您在执行$compile
之前错过了新it('Replaces the element with the appropriate content', () => {
// Compile a piece of HTML containing the directive
var scope = $rootScope.$new(); // create a new scope
var element = angular.element("<simple>not compiled</simple>");
var compiledElement = $compile(element)(scope);
// fire all the watches, so the scope expressions evaluate
scope.$digest();
// Check that the compiled element contains the templated content
expect(element.html()).toContain("COMPILED!");
});
的创建。你应该这样做:

我怀疑你没有正确导入指令。你试过了吗?
beforeEach(module('simple'));
您指示您尝试的替代版本不正确或是我没见过的模式:
beforeEach(() => {
let simpleComponent = new simpleModule(angular);
});
module('simple');
angular.module('simple');
答案 2 :(得分:0)
显而易见的是,您在测试中使用的是Javascript ES6。 Jasmine目前只了解ES5。
尝试使用此Jasmine ES6 Compiler,或在ES5中编写测试。
注意:您的测试没有被编译但是它们失败似乎是矛盾的。只有当业力试图运行它们时,它们才会失败。它们只能在编译后运行。你确定吗?
