问题 I am new TestNG and unit-testing in general. I am using TestNG 6.9.6 with Mockito 1.10.19 and PowerMock 1.6.4. I want to verify whether the myMethod() method in MyService class internally calls the static method Util.myStaticMethod with the correct arguments. Since verification of static methods is not natively supported in Mockito, I am using PowerMock along with it. My Test class is shown below: public class MyTest { private MyService myService; @Captor ArgumentCaptor<String> argCaptor;

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 前言之前写单测都是用mockito然后基于java来写单测，但是操作下来写单测确实很占用时间，而且有时候为了提高条件覆盖率，需要写大量的代码，那么该咋办呢？经过小伙伴的推荐，我去试了下Spock + Groovy，果然很好用，所以在这里特地记下来。操作那就不多废话了，如果想了解Spock理论知识的可以自行google一波。安装Groovy环境官网地址： http://www.groovy-lang.org/download.html 找一个自己喜欢的路径将他下载下来并解压配置环境变量 vi ~/.bash_profile 加入如下配置 # groovy export GROOVY_PATH=/Users/***/groovy/groovy-2.5.8/bin export PATH=$PATH:$GROOVY_PATH 验证 groovy -v 这样的话Groovy环境就ok啦！新建groovy目录接下去就自己新建路径，然后new Groovy Class即可注意点：如果想要统计覆盖率的话，记得要在idea中配置插件，如下：写法基本的语法大家可以自行查找一波，可以看W3C school。地址： https://www.w3cschool.cn/groovy/

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 前言成为一名优秀的Android开发，需要一份完备的知识体系，在这里，让我们一起成长为自己所想的那样~。 ==》完整项目单元测试学习案例众所周知，一个好的项目需要不断地打造，而一些有效的测试则是加速这一过程的利器。本篇博文将带你了解并逐步深入Android单元测试。什么是单元测试？单元测试就是针对类中的某一个方法进行验证是否正确的过程，单元就是指独立的粒子，在Android和Java中大都是指方法。为什么要进行单元测试？使用单元测试可以提高开发效率，当项目随着迭代越来越大时，每一次编译、运行、打包、调试需要耗费的时间会随之上升，因此，使用单元测试可以不需这一步骤就可以对单个方法进行功能或逻辑测试。同时，为了能测试每一个细分功能模块，需要将其相关代码抽成相应的方法封装起来，这也在一定程度上改善了代码的设计。因为是单个方法的测试，所以能更快地定位到bug。单元测试case需要对这段业务逻辑进行验证。在验证的过程中，开发人员可以深度了解业务流程，同时新人来了看一下项目单元测试就知道哪个逻辑跑了多少函数，需要注意哪些边界 ——是的，单元测试做的好和文档一样具备业务指导能力。 Android测试的分类 Android测试主要分为三个方面：单元测试（Junit4、Mockito
