使用maven-pom进行依赖管理与自动构建 使用maven-pom进行依赖管理与自动构建 一、让我们先了解一下maven 1.maven是优秀的依赖管理工具 2.maven是优秀的构建工具 3.maven是约定大于配置、简单易学的工具 二、pom基本结构 1.概览 2.项目坐标 3.package标签 4.项目间关系 5.dependencies标签 6.dependencyManagement标签 7.Properties标签 三、配置构建任务 1.maven构建的生命周期 2.插件的“构建阶段” 3.build标签 4.profiles标签 5.project标签下的build标签 5.Reporting标签 使用maven-pom进行依赖管理与自动构建 最后编辑于 :pencil: : {docsify-updated} 一、让我们先了解一下maven 1.maven是优秀的依赖管理工具 随着开发生态环境的不断发展,几乎所有的java应用都会使用第三方的类库,尤其是在这个开源的世界里, java应用依赖管理已经很难再由人工完成——依赖管理包括解决依赖传递、版本冲突、依赖臃肿等问题。 maven通过 groupId 、 artifactId 、 version 形成的坐标定位系统能准确的定位每一个构件(artifact), 开发者可以通过在pom文件中列出所依赖的构件的坐标

问题 I am in the middle of migrating a project into Java9, The Tests start failing after I switched to the new Java version, it seems like PowerMock is trying to access some classes it does not have access to. Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.973 sec <<< FAILURE! - in com.Test initializationError(com.Test) Time elapsed: 0.007 sec <<< ERROR! org.objenesis.ObjenesisException: java.lang.reflect.InvocationTargetException Caused by: java.lang.reflect

What does @PrepareForTest in PowerMock really mean?

问题 What does the annotation @PrepareForTest in PowerMockito really mean? What should be placed there apart of classes which have static methods? 回答1: That annotation tells PowerMock(ito) that the listed classes will need to be manipulated on the byte code level. You need to "prepare for test" all these classes X of which you want to mock a static method (on X) gain control over calls to new() used in another class X gain control over private methods (which you do using a spy and PowerMockito

Setting up Powemockito for static mocking

问题 I would like to make use of Powermock with Mockito to mock some static method calls. I have followed instructions and examples from SO as well as the PowerMock Getting Started and MockStatic pages as best I can, but I am yet to complete a mockStatic() call. When I call mockStatic(foo.class) from my test class, I'm given the excception: java.lang.NoClassDefFoundError: org/Mockito/mock/MockName at org.powermock.api.mockito.PowerMockito.mockStatic(PowerMockito.java:70) at ...my test class method

一、为什么要使用Mock工具 在做单元 测试 的时候,我们会发现我们要测试的方法会引用很多外部依赖的对象,比如:(发送邮件,网络通讯,远程服务, 文件系统等等)。 而我们没法控制这些外部依赖的对象,为了解决这个问题,我们就需要用到Mock工具来模拟这些外部依赖的对象,来完成单元测试。 二、为什么要使用PowerMock 现如今比较流行的Mock工具如 jMock 、 EasyMock 、 Mockito 等都有一个共同的缺点:不能mock静态、final、私有方法等。而 PowerMock 能够完美的弥补以上三个Mock工具的不足。 三、PowerMock简介 PowerMock是一个扩展了其它如EasyMock等mock框架的、功能更加强大的框架。PowerMock使用一个自定义类加载器和字节码操作来模拟静态方法,构造函数,final类和方法,私有方法,去除静态初始化器等等。通过使用自定义的类加载器,简化采用的IDE或持续集成服务器不需要做任何改变。熟悉PowerMock支持的mock框架的开发人员会发现PowerMock很容易使用,因为对于静态方法和构造器来说,整个的期望API是一样的。PowerMock旨在用少量的方法和注解扩展现有的API来实现额外的功能。目前PowerMock支持EasyMock和Mockito。 四、PowerMock入门
