由于 Firefox 强制要求我这样做,我正在重写我的扩展程序以使用 WebExtension API,即 Chrome 的 Extension API。我想要进行自动化测试。到目前为止,我尝试过以下方式:
我有一个 package.json 文件,因此 npm 将安装依赖项:
我有一个
我有基础测试:
当然,这只是一个简化的测试案例。当我运行
我的测试尝试使用扩展API都失败了。它并没有说(例如)
我有一个 package.json 文件,因此 npm 将安装依赖项:
{
"name": "extension-api-tests",
"version": "0.0.1",
"scripts": {
"test": "karma start"
},
"devDependencies": {
"karma": "^1.3.0",
"karma-firefox-launcher": "^1.0.0",
"karma-mocha": "^1.3.0",
"karma-sinon-chrome": "^0.2.0",
"mocha": "^3.1.2",
"sinon-chrome": "^2.1.2"
}
}
我有一个
karma.conf.js
来设置测试运行器:module.exports = function(config) {
config.set({
frameworks: ['mocha', 'sinon-chrome'],
files: ['test.js'],
reporters: ['dots'],
autoWatch: false,
browsers: ['Firefox'],
singleRun: true,
concurrency: Infinity,
});
};
我有基础测试:
describe('my frustration', () => {
it('works when it uses no APIs', done => {
done();
});
it('should respond to messages!', done => {
console.log('message test starting');
chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
console.log('received message');
sendResponse(true);
});
chrome.runtime.sendMessage({}, result => {
console.log('received response to message');
done();
});
});
it('should open a tab!', done => {
console.log('tab test starting');
chrome.tabs.create({
'active': true,
'url': 'http://www.example.com/',
}, tab => {
console.log('created a tab:', tab);
done();
});
});
});
当然,这只是一个简化的测试案例。当我运行
npm test
时,我会得到以下结果(略有缩写):> extension-api-tests@0.0.1 test .../ext-test
> karma start

我的测试尝试使用扩展API都失败了。它并没有说(例如)
chrome.runtime
未定义(但如果我从karma.conf.js中删除'sinon-chrome'
,它就会这样说),所以我相信我已经设置好了sinon。但是API永远不起作用,永远不起作用。我想要测试的代码完全围绕着通过这些API传递数据(特别是作为消息,跨越chrome/content边界)。
