testNG的常用用法Parameters，DataProvider

一、Parameters

在testng.xml中配置 里面的name值对应写到 Parameters中然后，在test中输出这个参数名，就可以得到配置中的value值

实例：

<suite name="Suite" parallel="classes" thread-count="3">
    <test verbose="2" preserve-order="true" name="TestDebug">
        <parameter name="Name" value="asdfsfa" />
        <classes>
            <class name="com.seventhDay.TestNG1" />
        </classes>
    </test> <!-- Test -->
</suite> <!-- Suite -->

    @Parameters("Name")
    @Test
    public void parametersTest(String Name){
        System.out.println(Name);
    }

结果：

asdfsfa

二、DataProvider

a.对象数据：

@Test(dataProvider = "testdb")
    public void parameterIntTest(Class clzz, String str,String line3, int no) {
		System.out.println(Thread.currentThread().getName());
       System.out.println("Parameterized Number is : " + clzz);
       System.out.println("Parameterized Number is : " + str);
       System.out.println("Parameterized Number is : " + line3);
       System.out.println("Parameterized Number is : " + no);
    }

@DataProvider(name = "testdb",parallel = false
    		)
    public Object[][] parameterIntTestProvider() {
        return new Object[][]{
                   {Vector.class, "test1","a",1},
                   {String.class, "test2","b",2},
                   {Integer.class, "test3","c",3},
                   {String.class, "test3","c",4},
                   {String.class, "test3","c",4}
                  };
    }

结果：

b.迭代器：

public class TestBean {
	
	private  String name;
	private  String msg;
	private  String line3;
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getMsg() {
		return msg;
	}
	public void setMsg(String msg) {
		this.msg = msg;
	}
}

public class TestBean2 {
	
	private  String name;
	private  String msg;
	private  String line3;
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getMsg() {
		return msg;
	}
	public void setMsg(String msg) {
		this.msg = msg;
	}
}

public class DataProviderTest2 {
	
	
	@Test(dataProvider = "mytest")
    public void parameterIntTest(TestBean bean,TestBean2 bean2) {
	   System.out.println(Thread.currentThread().getName()+" bean "+bean);
       System.out.println("Parameterized Number is : " + bean.getName());
       System.out.println("Parameterized Number is : " + bean2.getMsg());
    }

    @DataProvider(name = "mytest", parallel = true)
    public Iterator<Object[]> parameterIntTestProvider() {
    	List<Object[]> dataProvider = new ArrayList<Object[]>();
    	for(int i=0;i<2;i++){
    		TestBean bean = new TestBean();
    		bean.setName("testname"+i);
    		bean.setMsg("--"+i);
    		TestBean2 bean2 = new TestBean2();
    		dataProvider.add(new Object[] { bean,bean2});
    	}
        return dataProvider.iterator();
    }

}
