I am having a .Jar file that contains the files needed to runs on TestNG test.I want to run a specific xml file inside that Jar file.My requirement is that is it possible to execute TestNG test pointed to a .Jar file if so how can i do that.
xml file via command line allows user to run multiple testng xml files simultaneously. Before running a testng. xml suite through the command prompt, we need to compile our project code. We can find the compiled code by eclipse under a folder named “bin” inside the corresponding java project.
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.
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;
}
}
