如何运行指向罐子的TestNG测试

Question

我有一个.Jar文件，其中包含在TestNG test上运行所需的文件。我想在该Jar文件中运行特定的xml文件。我的要求是，如果可以的话，可以执行指向.Jar文件的TestNG测试我怎样才能做到这一点。

Answer 1

You can use the -xmlpathinjar suites/GroupBased_Tests.xml option to run your xml.
Can refer steps with maven here , if it helps.

For other options you can use, please refer Testng documentation here .

Answer 2

jar is a just a zip file.

You can get that extracted using jar xf testfile.jar and access the file you want.

This answer also might help you.

Read a file from inside of an external Jar file?

Answer 3

You can read the testng.xml and also run it programmatically without extracting the jar.

First you need to read the xml and parse it. Here I have created some bean classes to match with my xml file format. This is my bean class, create you own set of classes which match with your requirement

@XmlRootElement(name = "suite")
public class Suite {

private String name;
private String verbose = "1";
private boolean parallel =false;

private List<Test> testCases = new ArrayList<Test>();
private List<Parameter> parameters = new ArrayList<Parameter>();

@XmlAttribute
public String getName() {
    return name;
}


public void setName(String name) {
    this.name = name;
}

@XmlAttribute
public String getVerbose() {
    return verbose;
}


public void setVerbose(String verbose) {
    this.verbose = verbose;
}

@XmlAttribute
public boolean isParallel() {
    return parallel;
}


public void setParallel(boolean parallel) {
    this.parallel = parallel;
}

@XmlElement(name = "test")
public List<Test> getTestCases() {
    return testCases;
}

public void setTestCases(List<Test> testCases) {
    this.testCases = testCases;
}

@XmlElement(name = "parameter")
public List<Parameter> getParameters() {
    return parameters;
}


public void setParameters(List<Parameter> parameters) {
    this.parameters = parameters;
}
}

And this is how you read and parse it:

public Suite getTestSuiteFromJar(String jarFilePath, String filename) {
    File jarFile  = new File(jarFilePath);
    Suite suite = null;
    try {
        if (jarFile.isFile()) {
            final JarFile jar = new JarFile(jarFile);

            InputStream in = jar.getInputStream(new ZipEntry(filename));
            suite = XmlUtil.parseSuite(in);
            jar.close();
        }

    } catch (IOException | JAXBException | SAXException | ParserConfigurationException e) {
        e.printStackTrace();
    }
    return suite;
}

public static Suite parseSuite(InputStream is) throws JAXBException, SAXException, ParserConfigurationException {
    JAXBContext jaxbContext = JAXBContext.newInstance(Suite.class);
    Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
    return (Suite) jaxbUnmarshaller.unmarshal(is);
}

Finally we run the suite:

public static void runSuite(String jarFilePath, Suite s)
        throws MalformedURLException, ClassNotFoundException {
    //Don't confuse : XmlSuite here, is the standard testNg class. our bean class is Suite
    XmlSuite suite = new XmlSuite();
    suite.setName(s.getName());

    for (Test t : s.getTestCases()) {
        XmlTest test = new XmlTest(suite);
        test.setName(t.getName());
        List<XmlClass> classes = new ArrayList<XmlClass>();
        for (TestClass tc : t.getClasses()) {
            Class cls =  loadClass(jarFilePath, tc.getName());
            if (cls != null) {
                XmlClass xClass = new XmlClass(cls, false);
                classes.add(xClass);
                test.setXmlClasses(classes);
            }
        }
    }
    List<XmlSuite> suites = new ArrayList<XmlSuite>();

    suites.add(suite);
    TestNG tng = new TestNG();

    tng.setXmlSuites(suites);
    tng.run();
}

public Class loadClass(String jarFilePath, String className) throws MalformedURLException,
        ClassNotFoundException {
File jarFile  = new File(jarFilePath);
    if (jarFile.isFile()) {
        URL url = jarFile.toURL();
        URL[] urls = new URL[] { url };
        ClassLoader cl = new URLClassLoader(urls);
        return cl.loadClass(className);
    } else {
        return null;
    }
}
