TestNG参数化之@DataProvider传参

@parameters适合传递简单少量参数，复杂参数一般使用@DataProvider传递

@DataProvider语法：

@DataProvider(name = "dataproviderName")
public Object[][] createData([Method m]) {
   return Array;
}

@Test(dataprovider="dataproviderName"[, dataProviderClass = dataProviderClassName.class]) 
public void test(parameters...){ }

1.简单返回Array

test.java

    //This method will provide data to any test method that declares that its Data Provider
    //is named "test1"
    @DataProvider(name = "test1")
    public Object[][] createData1() {
     return new Object[][] {
       { "Cedric", new Integer(36) },
       { "Anne", new Integer(37)},
     };
    }
     
    //This test method declares that its data should be supplied by the Data Provider
    //named "test1"
    @Test(dataProvider = "test1")
    public void verifyData1(String n1, Integer n2) {
     System.out.println(n1 + ": " + n2);
    }

2.独立DataProvider类

StaticProvider.java——提供数据的类

public class StaticProvider {
  @DataProvider(name = "create")
  public static Object[][] createData() {
    return new Object[][] {
   { "Cedric", new Integer(36) },
   { "Anne", new Integer(37)},
 };
}

test.java

//This test method declares that its data should be supplied by the Data Provider
//named "test1"
@Test(dataProvider = "create", dataProviderClass = StaticProvider.class)
public void verifyData1(String n1, Integer n2) {
 System.out.println(n1 + " " + n2);
}

3.含参数的DataProvider类_参数为调用dataprovider的方法名

StaticProvider.java 

public class StaticProvider {
      @DataProvider(name = "create")
      public static Object[][] createData(Method m) {
        return getData(m.getName());
      }
          
      public static Object[][] getData(String methodName){
            .........
            ...........
            return Object[][];
      }      
}    

test.java

        //This test method declares that its data should be supplied by the Data Provider
        //named "test1"
        @Test(dataProvider = "create", dataProviderClass = StaticProvider.class)
        public void test1(String n1, Integer n2) {
         System.out.println(n1 + " " + n2);
        }

注意：dataProvider只能对使用@Test的方法使用
