TestNG:以编程方式运行测试-在执行测试方法时，XmlTest对象上设置的参数为空

Question

我想用TestNG以编程方式运行Test Suite。

我创建了测试结构:XmlSuite -> XmlTest -> TestClass(扩展XmlClass)

我在做三件事:

• 使用addParameter(String, String)向XmlTest添加参数
• 用setParameters(Map)设置参数为TestClass
• 在TestClass中设置变量Day

但是在测试执行时发生的是当它转到@Test方法时对象没有我之前设置的东西

public class TestRunner {
    public static void main(String[] args) {
        XmlSuite suite = new XmlSuite();
        suite.setName("TmpSuite");
        XmlTest test = new XmlTest(suite);
        test.setName("TmpTest");
        // Add parameter to XmlTest
        test.addParameter("testParam1", "clock");
        TestClass testClass = new TestClass();
        // Add parameter to XmlClass
        Map<String, String> testClassParameters = new HashMap<>();
        testClassParameters.put("classParam1", "valueOfClassParam1");
        testClass.setParameters(testClassParameters);
        // Set day variable
        testClass.setDay("Friday");
        testClass.setClass(TestClass.class);
        test.setXmlClasses(Arrays.asList(testClass)) ;
        TestNG tng = new TestNG();
        tng.setXmlSuites(Arrays.asList(suite));
        tng.run();
    }
}
public class TestClass extends XmlClass {
    private String day;
    @Test
    public void test1() {
        System.out.println("Day: " + day);
        System.out.println("LocalParameters: " + getLocalParameters());
        System.out.println("AllParameters: " + getAllParameters());
    }
    public void setDay(String day) {
        this.day = day;
    }
}

结果:

Day: null
LocalParameters: {}
------------> Exception

我想你应该做的是:

public class TestRunner {
    public static void main(String[] args) {
        // Add parameter to XmlClass
        Map<String, String> testClassParameters = new HashMap<>();
        testClassParameters.put("classParam1", "valueOfClassParam1");
        testClassParameters.put("day", "Friday");
        XmlClass testClass = new XmlClass();
        testClass.setParameters(testClassParameters);
        testClass.setClass(TestClass.class);    
        XmlSuite suite = new XmlSuite();
        suite.setName("TmpSuite");
        XmlTest test = new XmlTest(suite);
        test.setName("TmpTest");
        // Add parameter to XmlTest
        test.addParameter("testParam1", "clock");
        test.setXmlClasses(Arrays.asList(testClass)) ;
        TestNG tng = new TestNG();
        tng.setXmlSuites(Arrays.asList(suite));    
        tng.run();
    }
}
public class TestClass {
    @Parameters({ "day", "testParam1", "classParam1" })
    @Test
    public void test1(String day, String testParam1, String classParam1) {
        System.out.println("Day: " + day);
        System.out.println("testParam1: " + testParam1);
        System.out.println("classParam1: " + classParam1);
    }
}
