Question

我有3个测试，预计将连续运行。它们位于3个不同的类文件中，所有3个测试都来自另一个类中的dataProviders。我尝试将dependsOnGroups与dataProvider一起使用，如下所示：

 public class DataProviders { 
  @DataProvider(name = "Provider1")
  public static provider[][] A() throws Exception {
    ..............
  }     

  @DataProvider(name = "Provider2")
  public static provider[][] B() throws Exception {    
    .................      
}


@Test(groups="group1") 
public class TestClass1{

  @Test(dataProvider = "Provider1", dataProviderClass = DataProviders.class, enabled = true)
  public void Test1(provider file) throws Exception {
     ...............       
  }


public class TestClass2{

  @Test(groups="group2", dependsOnGroups="group1", dataProvider = "Provider2", dataProviderClass = DataProviders.class, enabled = true)
  public void test2(provider file) throws Exception {       
     ................
  }


public class TestClass3{

  @Test(dependsOnGroups="group2", dataProvider = "Provider2", dataProviderClass = DataProviders.class, enabled = true)
  public void test3(provider file) throws Exception {
     .................
  }

我的testng.xml文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">
    <test name="Test">
        <classes>
            <class name="a.b.c.d.TestClass1" />
            <class name="a.b.c.d.TestClass2" />
            <class name="a.b.c.d.TestClass3" />
        </classes>
    </test>
</suite>

从testng.xml文件执行测试时，只有第一个测试被执行，我得到以下testNG错误：

org.testng.TestNGException:

如果我将所有测试和dataProviders放在一个java类文件中，它就可以正常工作。

看起来你的例子不够饱满。这个按预期工作。

public class Provider {

    @DataProvider(name = "Provider1")
    public static Object[][] A() throws Exception {
        return new Object[][] { new Object[] {"Provider1-1"}, new Object[] {"Provider1-2"}};
    }

    @DataProvider(name = "Provider2")
    public static Object[][] B() throws Exception {
        return new Object[][] { new Object[] {"Provider2-1"}, new Object[] {"Provider2-2"}};
    }
}

@Test(groups="group1")
public class TestClass1 {
    @Test(dataProvider = "Provider1", dataProviderClass = Provider.class)
    public void Test1(String s) throws Exception {
        System.out.println("Test1 " + s);
    }
}

public class TestClass2 {
    @Test(groups = "group2", dependsOnGroups = "group1", dataProvider = "Provider2", dataProviderClass = Provider.class)
    public void test2(String s) throws Exception {
        System.out.printf("Test2 " + s);
    }
}

public class TestClass3 {
    @Test(dependsOnGroups = "group2", dataProvider = "Provider2", dataProviderClass = Provider.class)
    public void test2(String s) throws Exception {
        System.out.printf("Test3 " + s);
    }
}

使用testng.xml作为你的我有以下输出：

[root]
Test
TestClass1
TestClass1.test1[Provider1-1]
TestClass1.test1[Provider1-2] (1)
TestClass2
TestClass2.test2[Provider2-1]
TestClass2.test2[Provider2-2] (1)
TestClass3
TestClass3.test2[Provider2-1]
TestClass3.test2[Provider2-2] (1)

＆＃34; dependsOnGroups＆＃34;与@DataProvider
