java - 将 TestNG dataProvider 与 dependentOnGroups 结合使用来设置执行顺序

Question

我有几个相互依赖的测试用例。执行顺序可以在 TestNG 中使用 groups 定义。和 dependsOnGroups在@Test注释中:

public class MyTest {
    @Test(groups = { "group1" })
    public void testCase1() {
    }

    @Test(groups = {"group2"}, dependsOnGroups = { "group1" })
    public void testCase2() {
    }

    @Test(groups = {"group2"}, dependsOnGroups = { "group1" })
    public void testCase() {
    }

    @Test(groups = { "group3" }, dependsOnGroups = { "group2" })
    public void testCase4() {
    }
}

但我希望仅使用一个 @Test 方法和一个 @DataProvider 动态地为我提供组和依赖项。

public class MyTest {

    @Test(dataProvider = "test-cases", groups = {testCase[1]}, dependsOnGroups  = {testCase[2]})
    public void executeTest(TestCase testCase) throws Exception {
    }

    @DataProvider(name = "test-cases", parallel = true)
    public Object[][] getTestCases() {
        Object[][] testdata = new Object[...][...];
        // Fields: test name, group, depends on, test data 
        testdata[0] = {"TC#1", "group1", "",       "foo data"};
        testdata[1] = {"TC#2", "group2", "group1", "bar data"};
        testdata[2] = {"TC#3", "group2", "group1", "bzz data"};
        testdata[3] = {"TC#4", "group3", "group2", "frr data"};
        return testdata;
    }

}

不幸的是，这种方法不起作用，因为无法从 @Test(..., groups = {testCase[1]}, ...) 注释访问 testCase[1]。

是否有另一种方法可以使数据提供者驱动的测试按固定顺序进行？

Answer 1

根据您的评论和编辑，我认为您希望将数据获取到所有方法中，并按照它们在类中出现的顺序运行它们。

您可以使用以下方法和 testng.xml 以及 preserve-order="true" 来运行数据驱动测试。请注意，您可能必须删除 groups 和 dependsOnGroups 才能运行此程序，如下所示。

public class MyTest {

    @Test(dataProvider = "test-cases")     
    public void testCase1(Object[][] obj) {
        //access obj to get data
    }

    @Test(dataProvider = "test-cases")
    public void testCase2(Object[][] obj1) {
    //access obj1 to get data
    }

    @Test(dataProvider = "test-cases")
    public void testCase(Object[][] obj2) {
     //access obj2 to get data

    }

    @Test(dataProvider = "test-cases")
    public void testCase4(Object[][] obj3) {
         //access obj3 to get data
    }
}

这是您的 testng.xml，应按照它们出现的顺序运行它

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="yourSuiteName" >

    <test name="FirstScenario_1" preserve-order="true">

        <classes>  
         <class name="yourPackage.MyTest" >
               <methods> 
                  <include name="testCase1" />
                  <include name="testCase2" /> 
                  <include name="testCase" />
                  <include name="testCase4" />
               </methods> 
        </classes>
    </test>
</suite>
