摘要如下：
JUNIT做数据驱动的测试比较麻烦，所谓数据驱动的测试，就是比如同样的一个方法，能用EXCEL,CSV等格式提供大量的不同测试数据给测试去验证，这里可以使用
easytest这个不错的开源工具，地址在：https://github.com/EaseTech/easytest

下面例子讲解：

1）比如一个加法的：

Java代码 "收藏这段代码")

publicclass Calculator {
public Double add(Double a, Double b){
return a+b;
}
}

public class Calculator {

public Double add(Double a, Double b){
    return a+b;
}

}

2） MAVEN引入EASYTEST

Java代码 "收藏这段代码")

<dependency>
<groupId>org.easetech</groupId>
<artifactId>easytest-core</artifactId>
<version>1.4.0</version>
</dependency>

<groupId>org.easetech</groupId>
<artifactId>easytest-core</artifactId>
<version>1.4.0</version>

</dependency>

3 然后可以编制CSV或者EXCEL，记得第1列是要测试的方法名，内容留空，
然后是每列的参数

4 CSV测试的：

Java代码 "收藏这段代码")

@RunWith(DataDrivenTestRunner.class)
publicclass CSVLoaderExample extends DataDrivenTest {
@Test@DataLoader(filePaths = "calculator.csv", loaderType = LoaderType.CSV)
public String testAddFromCSV(@Param(name = "a") Double a,
@Param(name = "b") Double b,
@Param(name = "expected") Double expected) {
Assert.assertEquals(expected, calculator.add(a, b), 0.1);
return"success";
}
@Test@DataLoader(filePaths = "calculator2.csv")
publicvoid testAdd(@Param(name = "a") Double a, @Param(name = "b")Double b, @Param(name = "expected")Double expected){
Assert.assertEquals(expected, calculator.add(a,b),0.1);
}
}

@RunWith(DataDrivenTestRunner.class)
public class CSVLoaderExample extends DataDrivenTest {

@Test    @DataLoader(filePaths = "calculator.csv", loaderType = LoaderType.CSV)
public String testAddFromCSV(@Param(name = "a") Double a,
                             @Param(name = "b") Double b,
                             @Param(name = "expected") Double expected) {
    Assert.assertEquals(expected, calculator.add(a, b), 0.1);
    return "success";

}
@Test    @DataLoader(filePaths = "calculator2.csv")
public void testAdd(@Param(name = "a") Double a, @Param(name = "b")Double b, @Param(name = "expected")Double expected){
    Assert.assertEquals(expected, calculator.add(a,b),0.1);
}

}

首先继承DataDrivenTest ，然后用注解 @DataLoader(filePaths = "calculator.csv", loaderType = LoaderType.CSV) 标识是用CSV,XML还是EXCEL
然后@Param(name = "a")中的NAME就是对应EXCEL或CSV文件中的列的标题了

EXCEL也是一样：

Java代码 "收藏这段代码")

@RunWith(DataDrivenTestRunner.class)
publicclass ExcelLoaderExample extends DataDrivenTest {
@Test@DataLoader(filePaths = "calculator.xls", loaderType = LoaderType.EXCEL)
publicvoid testAddFromExcel(@Param(name = "a") Double a, @Param(name = "b") Double b, @Param(name = "expected") Double expected) {
Assert.assertEquals(expected, calculator.add(a, b), 0.1);
}
@Test@DataLoader(filePaths = {"calculator2.xls"})
publicvoid testAdd(@Param(name = "a") Double a, @Param(name = "b")Double b, @Param(name = "expected")Double expected){
Assert.assertEquals(expected, calculator.add(a,b),0.1);
}
}

@RunWith(DataDrivenTestRunner.class)
public class ExcelLoaderExample extends DataDrivenTest {

@Test    @DataLoader(filePaths = "calculator.xls", loaderType = LoaderType.EXCEL)
public void testAddFromExcel(@Param(name = "a") Double a, @Param(name = "b") Double b, @Param(name = "expected") Double expected) {
    Assert.assertEquals(expected, calculator.add(a, b), 0.1);
}
@Test    @DataLoader(filePaths = {"calculator2.xls"})
public void testAdd(@Param(name = "a") Double a, @Param(name = "b")Double b, @Param(name = "expected")Double expected){
    Assert.assertEquals(expected, calculator.add(a,b),0.1);
}

}

4 还有不错的报表功能，可以输出：

Java代码 "收藏这段代码")

@RunWith(DataDrivenTestRunner.class)
@Report(outputLocation = "classpath:TestReports")
publicclass ClassPathExampleReport extends DataDrivenTest{
@Test@DataLoader(filePaths = "calculator.xls")
publicvoid testAddFromExcel(@Param(name = "a") Double a, @Param(name = "b") Double b, @Param(name = "expected") Double expected) {
Assert.assertEquals(expected, calculator.add(a, b), 0.1);
}
@Test@DataLoader(filePaths = "calculator2.xls")
publicvoid testAdd(@Param(name = "a") Double a, @Param(name = "b") Double b, @Param(name = "expected") Double expected) {
Assert.assertEquals(expected, calculator.add(a, b), 0.1);
}
}

@RunWith(DataDrivenTestRunner.class)
@Report(outputLocation = "classpath:TestReports")
public class ClassPathExampleReport extends DataDrivenTest{

@Test    @DataLoader(filePaths = "calculator.xls")
public void testAddFromExcel(@Param(name = "a") Double a, @Param(name = "b") Double b, @Param(name = "expected") Double expected) {
    Assert.assertEquals(expected, calculator.add(a, b), 0.1);
}
@Test    @DataLoader(filePaths = "calculator2.xls")
public void testAdd(@Param(name = "a") Double a, @Param(name = "b") Double b, @Param(name = "expected") Double expected) {

    Assert.assertEquals(expected, calculator.add(a, b), 0.1);
}

}

这样就在TARGET目录下有个目录是TestReports，
