篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了测试chrome扩展 - 需要错误相关的知识，希望对你有一定的参考价值。
我有这个gulp任务：
gulp.task('test', function () {
return gulp.src('test/runner.html')
.pipe(mochaPhantomJS());
});
这是我的runner.html：
<!DOCTYPE html>
<html>
<head>
<title>Mocha</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="../node_modules/mocha/mocha.css" />
</head>
<body>
<script src="../node_modules/mocha/mocha.js"></script>
<script>mocha.setup('bdd')</script>
<script src="../node_modules/chai/chai.js"></script>
<script src="../node_modules/requirejs/require.js"></script>
<script>
var assert = chai.assert;
var expect = chai.expect;
var should = chai.should();
</script>
<script src="spec/test.js"></script>
<script>
if (window.mochaPhantomJS) {
console.log('Running mochaPhantomJS...');
mochaPhantomJS.run();
} else {
console.log('Running mocha...');
mocha.run();
}
</script>
</body>
</html>
这是我的test.js文件：
var chrome = require('sinon-chrome');
var popup = require('../../source/scripts/popup');
describe('sumit', function(){
before(function () {
global.chrome = chrome;
});
it('Should return 1', function(){
assert(popup.sum(0,1) === 1);
});
})
但是，当我运行gulp test时，我收到此错误消息：
错误：尚未为上下文加载模块名称“sinon-chrome”：_。使用require（[]）
http://requirejs.org/docs/errors.html#notloaded
在文件中的defaultOnError：/// c：/dev/extensions/NEW_EXPRESS/node_modules/requirejs/require.js：文件中的onError中的1：/// c：/dev/extensions/NEW_EXPRESS/node_modules/requirejs/require.js ：547 in localRequire at file：/// c：/dev/extensions/NEW_EXPRESS/node_modules/requirejs/require.js：1433 in requirejs at file：/// c：/ dev / extensions / NEW_EXPRESS / node_modules / requirejs / require .js文件：1794
在link in the error message中，它意味着你应该使用异步require方法。
因此，如果您将test.js更新为以下内容，那么它应该解决该问题：
require(['sinon-chrome'], function (chrome) {
var popup = require('../../source/scripts/popup');
describe('sumit', function(){
before(function () {
global.chrome = chrome;
});
it('Should return 1', function(){
assert(popup.sum(0,1) === 1);
});
})
});
在Angular 7版本中，您可以执行此操作。
Karma.config：
config.set({
basePath: '',
frameworks: ['jasmine', '@angular-devkit/build-angular'],
plugins: [
require('karma-jasmine'),
require('karma-chrome-launcher'),
require('karma-jasmine-html-reporter'),
require('karma-coverage-istanbul-reporter'),
require('@angular-devkit/build-angular/plugins/karma')
],
client: {
clearContext: false // leave Jasmine Spec Runner output visible in browser
},
coverageIstanbulReporter: {
dir: require('path').join(__dirname, '../coverage'),
reports: ['html', 'lcovonly'],
fixWebpackSourcePaths: true
},
reporters: ['kjhtml', 'progress'],
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: true,
browsers: ['Chrome'],
singleRun: false
});
在你的测试中：
import * as chrome from 'sinon-chrome';
import {MyService} from '../my.service';
describe('RunTaskService', () => {
beforeEach(() => {
TestBed.configureTestingModule({});
(global as any).chrome = chrome;
});
it('should be start a task', done => {
const service: MyService = TestBed.get(MyService);
expect(service).toBeTruthy();
chrome.runtime.lastError = null;
chrome.tabs.query.yields([{url: 'https://cnn.com', id: 123}]);
// call your code to test. the chrome.tabs.query will
// return [{url: 'https://cnn.com', id: 123}]
});
