Question

我需要根据测试的参数以编程方式生成测试套件。

这是主要功能：

public class DataValidator {
public static void main (String args[]) {
    TestState testState = new TestState();

    //Create an instance on TestNG
    TestNG testNg = new TestNG();

    List<XmlSuite> suites = new ArrayList<XmlSuite>();

    TestRunner testRunner = new TestRunner(testState);
    XmlSuite testSuite = testRunner.generateSuite();

    suites.add(testSuite);
    testNg.setXmlSuites(suites);
    testNg.run();
}   
}

这是生成测试套件的测试运行程序

public class TestRunner {
   private TestState testState;

public TestRunner(TestState testState) {
    this.testState = testState;
}


public XmlSuite generateSuite( ) {
    XmlSuite testSuite = new XmlSuite();
    XmlTest xmlTest = new XmlTest();
    xmlTest.setName("TestState");    

    List<XmlClass> xmlClasses = new ArrayList<XmlClass>();

    xmlClasses.add(new XmlClass(JobCreated.class.getName()));
    xmlTest.setXmlClasses(xmlClasses);
    testSuite.addTest(xmlTest);
    return testSuite;
}

这是工作创造的课程

public class JobCreated {

@Test
public void test1() {
    System.out.println("passed test 1");
}
}

当我作为Java应用程序运行测试时，我得到以下NullPointerException：

Exception in thread "main" java.lang.NullPointerException
at org.testng.xml.XmlTest.getVerbose(XmlTest.java:249)
at org.testng.TestRunner.init(TestRunner.java:212)
at org.testng.TestRunner.<init>(TestRunner.java:167)

at org.testng.TestNG.run(TestNG.java:1017)
at data_validator_testng.DataValidator.main(DataValidator.java:39)

我无法理解导致此错误的原因。

因为XmlTest和m_suite之间没有正确的链接为空

/**
* @return Returns the verbose.
*/
public int getVerbose() {
  Integer result = m_verbose;
  if (null == result || XmlSuite.DEFAULT_VERBOSE.equals(m_verbose)) {
    result = m_suite.getVerbose(); 
}

通过在XmlTest的构造函数中添加testSuite进行了纠正

XmlTest xmlTest = new XmlTest(testSuite);
