用maven搭建 testNG+PowerMock+Mockito测试框架

单元测试是开发中必不可少的一部分，是产品代码的重要保证。

Junit和testNG是当前最流行的测试框架，Junit是使用最广泛的测试框架，有兴趣的话自己baidu一下。

testNG基于Junit和Ｎunit,并引入了很多特性，使其更强大和更易于使用。

有兴趣的可以直接看一下官网：http://testng.org/doc/index.html

用maven可以很方便的构建测试框架。

在这里以maven为例搭建一个测试框架

编辑pom.xml引入必要的jar包

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <powermock.version>1.6.3</powermock.version>
        <cobertura.version>2.1.1</cobertura.version>
        <sonar.version>5.1</sonar.version>
        <junit.version>4.12</junit.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.powermock</groupId>
            <artifactId>powermock-module-testng</artifactId>
            <version>${powermock.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.powermock</groupId>
            <artifactId>powermock-api-mockito</artifactId>
            <version>${powermock.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>net.sourceforge.cobertura</groupId>
            <artifactId>cobertura</artifactId>
            <version>${cobertura.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.codehaus.sonar</groupId>
            <artifactId>sonar-plugin-api</artifactId>
            <version>${sonar.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.powermock</groupId>
            <artifactId>powermock-module-junit4</artifactId>
            <version>${powermock.version}</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

基本的框架已经搭建，下面写一个最简单的测试类

很多例子取自<<PowerMock实战手册>><<Instant Mock Testing with PowerMock>>

http://wenku.baidu.com/link?url=hKW9B15IRoqIrjpWKYDeR_cGL9hRgYvbT7-rbds59i19l70qzGeW7x3Tzr24Vwuq-vWHggOq6XOs_saW33Li7E492UlXWM8JIpyKMyhvhwa

待测试类：

public class EmployeeService {    

    public String hello(){
        return "Hello word!";
    }
}

测试类：

public class EmployeeServiceTest {
    @Test
    public void hello(){
        Assert.assertEquals(employeeService.hello(), "Hello word!");
    }
}

这是一个不能再简单的例子了，如果ＩＤＥ有testNG插件的话，直接右键EmployeeServiceTest→run as→testNG test就可以运行。

结果如下：

[TestNG] Running:
  C:\Users\changzhz\AppData\Local\Temp\testng-eclipse--447685701\testng-customsuite.xml

PASSED: hello

===============================================
    Default test

[TestNG] Time taken by org.testng.reporters.XMLReporter@27ddd392: 13 ms

或者用maven运行　：mvn clean test

用maven调用时，请确保测试类以Test或testCase结尾

这个例子太简单了，只是简单说明怎么构架，怎么运行。
