Defining behaviour once for test class (by @BeforeClass annotation) causes: first test invocation to return mocked value second test invocation to return real method return value Sample code: import org.junit.Assert; import org.junit.BeforeClass; import org.junit.Test; import org.junit.runner.RunWith; import org.powermock.api.mockito.PowerMockito; import org.powermock.core.classloader.annotations.PrepareForTest; import org.powermock.modules.junit4.PowerMockRunner

That ( someList , Has . Member ( someMember )); I like this kind of code because it is easily readable by looking like English. I am playing with Rust to see if I can create a library that gives the same feelings: use std :: fmt :: Debug ; struct Is ; enum Verb < T > { EqualTo ( T ), } impl Is { fn equal_to < T >(& self , obj : T ) -> Verb < T > { Verb :: EqualTo ( obj ) } } #[allow(non_upper_case

Why do so many assertEquals() or similar function take the expected value as first parameter and the actual one as second ? This seems counter-intuitive to me, so is there a particular reason for this unusual order ? bmargulies Because the authors had a 50% chance of matching your intuition. Because of the other overload assertWhatever(explanation, expected, actual) And the explanation, which is part of what you know, goes with the expected, which is what you know, as opposed to the actual, which you don't know at the time you write the code. I agree with the consensus that consistency is #1,

My (so far unsuccessful) attempt is: struct TypeC { struct subtype { static_assert(false, "Attempt to access the non-existent subtype of TypeC."); }; }; But static_assert(false, ...) can't work, as

I keep getting this assert: java.lang.IllegalArgumentException: You must call this method on the main thread but according to this thread, it should work: https://github.com/bumptech/glide/issues/310 Yet, I cannot get it to work, unless I call it from the main thread. Here's is what I am trying to do from the main thread: Glide.get(mContext); loadUserImage(userImageUrl); // wait 5 seconds before trying again int imageLoadingTimeOut = mContext.getResources().getInteger(R.integer

最终也是最重要的 store.js ，该文件主要涉及的内容如下： Store类 genericSubscribe函数 resetStore函数 resetStoreVM函数 installModule函数 makeLocalContext函数 makeLocalGetters函数 registerMutation函数 registerAction函数 registerGetter函数 enableStrictMode函数 getNestedState函数 unifyObjectStyle函数 install函数 let Vue 上面这些和 这个Vue 都在同一个作用域 install export function install (_Vue) { if (Vue && _Vue === Vue) { if (process.env.NODE_ENV !== ‘production‘) { console.error( ‘[vuex] already installed. Vue.use(Vuex) should be called only once.‘ ) } return } Vue = _Vue applyMixin(Vue) } 解析： 主要是让所有组件都能拿到store,在组件生命周期 beforeCreate 期间给所有组件创建 $store

在做单元测试的时候，有的时候用到的一些类，我们构造起来不是那么容易，比如HttpRequest，或者说某个Service依赖到了某个Dao，想构造service还得先构造dao，这些外部对象构造起来比较麻烦。 所以出现了Mock! 我们可以用 Mock 工具来模拟这些外部对象，来完成我们的单元测试。 　　实现Mock技术的优秀开源框架有很多，下面以Mockito为例，用几个简单例子来介绍Mock工具的基本使用： @Test public void simpleTest (){ // mock List<String> list = Mockito. mock (List. class ) ; // list.get(0) helloworld // Mock List Mock 瀵硅薄 // Mock List // Mock // Mock get(0) Mockito. when (list.get( 0 )).thenReturn( "helloworld" ) ; //list.get(0) helloworld String result = list.get( 0 ) ; System. out .println(result) ; // ( get(0)) Mockito. verify (list).get( 0 ) ; Assert. assertEquals (
