阅读更多关于 Android TDD: The saga continues with Robolectric & Gradle

问题 Just when I'd achieved an effective development and build environment with the android-maven-plugin , the new kid on the block, Gradle, starts making inroads into the Android circles. Not being hot on Groovy and with the android-gradle plugin almost as fragmented as the OS itself I've hit some issues. Specifically around building library projects, with flavours and our buddy Robolectric . Short version I am at a loss as to what my next move should be upon encountering the gradle error; Cannot

How to detect if a mocha test is running in node.js?

阅读更多关于 How to detect if a mocha test is running in node.js?

I want to make sure that in case the code is running in test mode, that it does not (accidentally) access the wrong database. What is the best way to detect if the code is currently running in test mode? As already mentioned in comment it is bad practice to build your code aware of tests. I even can't find mentioned topic on SO and even outside. However, I can think of ways to detect the fact of being launched in test. For me mocha doesn't add itself to global scope, but adds global.it . So your check may be var isInTest = typeof global.it === 'function'; I would suggest to be sure you don't

问题 I'm attempting to test a React component with Jest/Enzyme while using Webpack. I have a very simple test @ import React from 'react'; import { shallow } from 'enzyme'; import App from './App'; it('App', () => { const app = shallow(<App />); expect(1).toEqual(1); }); The relative component it's picking up is : import React, { Component } from 'react'; import { render } from 'react-dom'; // import './styles/normalize.css'; class App extends Component { render() { return ( <div>app</div> ); } }

Testing Chef roles and environments

问题 I'm new to Chef and have been using Test Kitchen to test the validity of my cookbooks, which works great. Now I'm trying to ensure that environment-specific attributes are correct on production nodes prior to running Chef initially. These would be defined in a role. For example, I may have recipes that converge using a Vagrant box with dev settings, which validates the cookbook. I want to be able to test that a production node's role. I think I want these tests as the source of truth

RhinoMock : Mocks Vs StrictMocks Vs DynamicMocks

阅读更多关于 RhinoMock : Mocks Vs StrictMocks Vs DynamicMocks

问题 I understand the difference between a Mock and a Stub. But different types of Mocks in RhinoMock framework confuses me. Could someone explain the concepts of Mocks Vs StrictMocks Vs DynamicMocks in terms of RhinoMock framework. your answers are greatly appreciated. 回答1: A strict mock is a mock that will throw an exception if you try to use any method that has not explicitly been set up to be used. A dynamic (or loose) mock will not throw an exception if you try to use a method that is not set
