安装Chrome个人资料的扩展程序 量angular器

如何检查扩展是否被安装？ 我已经手动尝试，并没有看到它，但我能够在Firefox中看到它。

helper.js：

var q = require('q'); var fs = require('fs'); exports.getCapabilities = function (filename) { var deferred = q.defer(); fs.readFile(filename, function (err, data) { var capabilities = { 'browserName': 'chrome', 'chromeOptions': { extensions: [ data.toString('base64') ] } }; deferred.resolve(capabilities); }); return deferred.promise; }; var helper = require('./helper.js'); directConnect: false, exports.config = { specs: ['spec.js'], chromeDriver: "chromedriver", framework: 'jasmine2', getMultiCapabilities: helper.getCapabilities("face.crx") };
