另一个TestNG参数测试示例,是使用@DataProvider
注解。
1. CharUtil类
创建一个将字符转换成ASCII或者副词的类,如何使用TestNG来做单元测试?
打开 Eclipse 创建一个 Maven 工程: ParameterTesting,其目录结构如下所示 -
类文件:CharUtils.java 的代码如下 -
package com.yiibai;
/**
* Character Utility class
*
* @author yiibai
*
*/
public class CharUtils {
/**
* Convert the characters to ASCII value
*
* @param character character
* @return ASCII value
*/
public static int CharToASCII(final char character) {
return (int) character;
}
/**
* Convert the ASCII value to character
*
* @param ascii ascii value
* @return character value
*/
public static char ASCIIToChar(final int ascii) {
return (char) ascii;
}
}
2. TestNG @DataProvider示例
要测试它,创建一个接受两个参数(字符和预期ASCII)的@Test方法,并且测试数据从数据提供者传递。
创建一个类文件:CharUtilsTest.java 的代码如下 -
package com.yiibai;
import org.testng.Assert;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
/**
* Character Utils Testing
* @author
*
*/
public class CharUtilsTest {
@DataProvider
public Object[][] ValidDataProvider() {
return new Object[][]{
{ 'A', 65 },{ 'a', 97 },
{ 'B', 66 },{ 'b', 98 },
{ 'C', 67 },{ 'c', 99 },
{ 'D', 68 },{ 'd', 100 },
{ 'Z', 90 },{ 'z', 122 },
{ '1', 49 },{ '9', 57 }
};
}
@Test(dataProvider = "ValidDataProvider")
public void CharToASCIITest(final char character, final int ascii) {
int result = CharUtils.CharToASCII(character);
Assert.assertEquals(result, ascii);
}
@Test(dataProvider = "ValidDataProvider")
public void ASCIIToCharTest(final char character, final int ascii) {
char result = CharUtils.ASCIIToChar(ascii);
Assert.assertEquals(result, character);
}
}
执行上面测试类,得到结果如下 -
