TestNG:一个@Test的多个@DataProvider

问题描述

我正在将TestNG用于Eclipse.

是否可以为两个数据提供者逐步提供相同测试功能?

Is it possible to give two data providers step by step to the same test-function?

我可以将两个提供程序合而为一，但这不是我想要的.

I could put both providers in one, but that is not what I want.

我需要(与本例不同)独立生成数据.

I need (not like in this example) to generate independently data.

@DataProvider(name = "dataSet1")

    public Object[][] createDataX() {
             return new Object[][] { { 1, 1 }, { 2, 2 } };
    }

@DataProvider(name = "dataSet2")

    public Object[][] createDataY() {
             return new Object[][] { { 0, 0 }, { 3, 3 } };
    }

我想让两个提供商都接受相同的测试.这可能吗?

I want to give both providers to the same test. Is this possible?

 @Test(dataProvider = "dataSet1") // ??? and "dataSet2" ???
    public void testThisFunction(int val1, int val2) {
            boolean solution = oracle(val1,val2);
            assert (solution);
   }

推荐答案

否，但是没有什么可以阻止您将这两个数据提供程序合并为一个并指定一个作为您的数据提供程序:

No, but nothing stops you from merging these two data providers into one and specifying that one as your data provider:

public Object[][] dp1() {
  return new Object[][] {
      new Object[] { "a", "b" },
      new Object[] { "c", "d" },
  };
}

public Object[][] dp2() {
  return new Object[][] {
      new Object[] { "e", "f" },
      new Object[] { "g", "h" },
  };
}

@DataProvider
public Object[][] dp() {
  List<Object[]> result = Lists.newArrayList();
  result.addAll(Arrays.asList(dp1()));
  result.addAll(Arrays.asList(dp2()));
  return result.toArray(new Object[result.size()][]);
}

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