TestNG：如何使用 DataProvider 提供的数据按顺序执行多个测试方法

Question

有没有办法使用来自数据提供者的不同数据按顺序执行多个测试方法？

例如

@DataProvider(name = "test1")
public Object[][] createData1() {
    return new Object[][] {
        { "Cedric", new Integer(36) },
        { "Anne", new Integer(37)}, 
    };
}


@Test(dataProvider = "test1")
public void verifyData1(String n1, Integer n2) {
    System.out.println(n1 + " " + n2);
}

@Test
public void verifyData2() {
    System.out.println("Verify2");
}

运行它的输出将是

安妮 37

为什么不在该类中使用多个数据提供者？

@DataProvider(name = "test1")
public Object[][] createData1() {
    return new Object[][] {
        { "Cedric", new Integer(36) },
        { "Anne", new Integer(37)}, 
    };
}

@DataProvider(name = "test2")
public Object[][] createData2() {
    return new Object[][] {
        { "Amir", new Integer(42) },
        { "Alice", new Integer(39)}, 
    };
}


@Test(dataProvider = "test1")
public void verifyData1(String n1, Integer n2) {
    System.out.println(n1 + " " + n2);
}

@Test(dataProvider = "test2")
public void verifyData2(String n1, Integer n2) {
    System.out.println(n1 + " " + n2);
}

这里有一种方法：使用注解来指定哪个方法应该接收哪些数据：

public class A {

  @DataProvider
  public Object[][] dp(Method m) {
    if (m.getAnnotation(Different.class) != null) {
      return new Object[][] {
          new Object[] { "different-a", "different-b" },
          new Object[] { "different-c", "different-d" },
        };
      } else {
        return new Object[][] {
            new Object[] { "c", "d" },
            new Object[] { "a", "b" },
        };
      }
    }

  @Test(dataProvider = "dp")
  public void test1(String a, String b) {
    System.out.println("test1: " + a + " " + b);
  }

  @Different
  @Test(dataProvider = "dp")
  public void test2(String a, String b) {
    System.out.println("test2: " + a + " " + b);
  }
}

注释：

@Retention(java.lang.annotation.RetentionPolicy.RUNTIME)
@Target({METHOD})
public @interface Different {}

输出：

test1: c d
test1: a b
test2: different-a different-b
test2: different-c different-d
