Hi I'm getting null pointer exception while executing a sample spring batch job. Exception is thrown from job launcher. This is my job launcher code. Thanks in advance.
public class NewJobRunner {
public static Job job;
public static JobLauncher jobLauncher;
public static JobRepository jobRepository;
public static void main(String args[]) {
try {
AbstractApplicationContext applicationContext = new ClassPathXmlApplicationContext("/resources/job-context.xml");
jobLauncher.run(job, new JobParametersBuilder()
.toJobParameters()
);
}catch(Exception e) {
e.printStackTrace();
}
}
public void setJobLauncher(JobLauncher jobLauncher) {
this.jobLauncher = jobLauncher;
}
public void setJobRepository(JobRepository jobRepository) {
this.jobRepository = jobRepository;
}
public void setJob(Job job) {
this.job = job;
}

My issue is mainly to know how to populate TestRail results after Cucumber scenarios are run. I'm trying to have the results from my JUnit tests run set on an existing TestRail run. I have the APIClient and APIException as per this project. I then created this JUnit class also copying that same project. Not sure how to proceed now as first time using Cucumber and JUnit. Our project has also a Hooks class and a MainRunner if that helps?
public class Hooks {
public static WebDriver driver;
#Before
public void initializeTest() {
System.out.println("Testing whether it starts before every scenario");
driver = DriverFactory.startDriver();
}
}
import java.io.File;
#RunWith(Cucumber.class)
#CucumberOptions(
features = {"src/test/java/clinical_noting/feature_files/"},
glue = {"clinical_noting.steps", "clinical_noting.runner"},
monochrome = true,
tags = {"#current"},
plugin = {"pretty", "html:target/cucumber",
"json:target/cucumber.json",
"com.cucumber.listener.ExtentCucumberFormatter:target/cucumber-
reports/report.html"}
)
public class MainRunner {
#AfterClass
public static void writeExtentReport() {
Reporter.loadXMLConfig(new File(FileReaderManager.getInstance().getConfigReader().getReportConfigPath()))
;
}
}
Thanks for the help.
Update
Got TestRail to update when running the JUnit tests separately. Still not sure how to do it after the Cucumber scenario is run though? That's how it's working now:
public class JUnitProject {
private static APIClient client = null;
private static Long runId = 3491l;
private static String caseId = "";
private static int FAIL_STATE = 5;
private static int SUCCESS_STATE = 1;
private static String comment = "";
#Rule
public TestName testName = new TestName();
#BeforeClass
public static void setUp() {
//Login to API
client = testRailApiClient();
}
#Before
public void beforeTest() throws NoSuchMethodException {
Method m = JUnitProject.class.getMethod(testName.getMethodName());
if (m.isAnnotationPresent(TestRails.class)) {
TestRails ta = m.getAnnotation(TestRails.class);
caseId = ta.id();
}
}
#TestRails(id = "430605")
#Test
public void validLogin() {
comment = "another comment";
Assert.assertTrue(true);
}
#Rule
public final TestRule watchman = new TestWatcher() {
Map data = new HashMap();
#Override
public Statement apply(Statement base, Description description) {
return super.apply(base, description);
}
#Override
protected void succeeded(Description description) {
data.put("status_id", SUCCESS_STATE);
}
// This method gets invoked if the test fails for any reason:
#Override
protected void failed(Throwable e, Description description) {
data.put("status_id", FAIL_STATE);
}
// This method gets called when the test finishes, regardless of status
// If the test fails, this will be called after the method above
#Override
protected void finished(Description description) {
try {
data.put("comment", comment);
client.sendPost("add_result_for_case/" + runId + "/" + caseId, data);
} catch (IOException e) {
e.printStackTrace();
} catch (APIException e) {
e.printStackTrace();
}
};
};
}
And the annotation
#Retention(RetentionPolicy.RUNTIME)
#Target(ElementType.METHOD) //on method level
public #interface TestRails {
String id() default "none";
}
Working now. Had to add the scenario param inside the before method and do the TestRail connection from there.
#regressionM1 #TestRails(430605)
Scenario: Verify the user can launch the application
Given I am on the "QA-M1" Clinical Noting application
Then I should be taken to the clinical noting page
And
public class Hooks {
private static APIClient client = null;
private static Long runId = 3491l;
private static String caseId = "";
private static int FAIL_STATE = 5;
private static int SUCCESS_STATE = 1;
private static String SUCCESS_COMMENT = "This test passed with Selenium";
private static String FAILED_COMMENT = "This test failed with Selenium";
#Rule
public TestName testName = new TestName();
public static WebDriver driver;
#Before
public void initializeTest() {
client = testRailApiClient();
System.out.println("Testing whether it starts before every scenario");
driver = DriverFactory.startDriver();
}
#After()
public void tearDown(Scenario scenario) {
String caseIdSplit = "";
for (String s : scenario.getSourceTagNames()) {
if (s.contains("TestRail")) {
caseIdSplit = s.substring(11, 17); // Hardcoded for now as all the ids have 6 characters
System.out.println("Testing whether the browser closes after every scenario" + caseIdSplit);
}
}
caseId = caseIdSplit;
Map data = new HashMap();
if (!scenario.isFailed()) {
data.put("status_id", SUCCESS_STATE);
data.put("comment", SUCCESS_COMMENT);
} else if (scenario.isFailed()) {
data.put("status_id", FAIL_STATE);
data.put("comment", SUCCESS_COMMENT);
}
try {
client.sendPost("add_result_for_case/" + runId + "/" + caseId, data);
} catch (IOException e) {
e.printStackTrace();
} catch (APIException e) {
e.printStackTrace();
}
}
}

Wrote a post on this here
We want to write compressed data to HDFS by Flink's BucketingSink or StreamingFileSink. I have write my own Writer which works fine if no failure occurs. However when It encounters a failure and restart from checkpoint, It will generate valid-length file(hadoop < 2.7) or truncate the file. Unluckily gzips are binary files which have trailer at the end of file. Therefore simple truncation does not work in my case. Any ideas to enable exactly-once semantic for compression hdfs sink?
That's my writer's code:
public class HdfsCompressStringWriter extends StreamWriterBaseV2<JSONObject> {
private static final long serialVersionUID = 2L;
/**
* The {#code CompressFSDataOutputStream} for the current part file.
*/
private transient GZIPOutputStream compressionOutputStream;
public HdfsCompressStringWriter() {}
#Override
public void open(FileSystem fs, Path path) throws IOException {
super.open(fs, path);
this.setSyncOnFlush(true);
compressionOutputStream = new GZIPOutputStream(this.getStream(), true);
}
public void close() throws IOException {
if (compressionOutputStream != null) {
compressionOutputStream.close();
compressionOutputStream = null;
}
resetStream();
}
#Override
public void write(JSONObject element) throws IOException {
if (element == null || !element.containsKey("body")) {
return;
}
String content = element.getString("body") + "\n";
compressionOutputStream.write(content.getBytes());
compressionOutputStream.flush();
}
#Override
public Writer<JSONObject> duplicate() {
return new HdfsCompressStringWriter();
}
}
I would recommend to implement a BulkWriter for the StreamingFileSink which compresses the elements via a GZIPOutputStream. The code could look the following:
public static void main(String[] args) throws Exception {
StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
env.setParallelism(1);
env.enableCheckpointing(1000);
final DataStream<Integer> input = env.addSource(new InfinitySource());
final StreamingFileSink<Integer> streamingFileSink = StreamingFileSink.<Integer>forBulkFormat(new Path("output"), new GzipBulkWriterFactory<>()).build();
input.addSink(streamingFileSink);
env.execute();
}
private static class GzipBulkWriterFactory<T> implements BulkWriter.Factory<T> {
#Override
public BulkWriter<T> create(FSDataOutputStream fsDataOutputStream) throws IOException {
final GZIPOutputStream gzipOutputStream = new GZIPOutputStream(fsDataOutputStream, true);
return new GzipBulkWriter<>(new ObjectOutputStream(gzipOutputStream), gzipOutputStream);
}
}
private static class GzipBulkWriter<T> implements BulkWriter<T> {
private final GZIPOutputStream gzipOutputStream;
private final ObjectOutputStream objectOutputStream;
public GzipBulkWriter(ObjectOutputStream objectOutputStream, GZIPOutputStream gzipOutputStream) {
this.gzipOutputStream = gzipOutputStream;
this.objectOutputStream = objectOutputStream;
}
#Override
public void addElement(T t) throws IOException {
objectOutputStream.writeObject(t);
}
#Override
public void flush() throws IOException {
objectOutputStream.flush();
}
#Override
public void finish() throws IOException {
objectOutputStream.flush();
gzipOutputStream.finish();
}
}
The code of my program to be attached is as below.
public class Foo {
}
public class TestEntry {
public TestEntry() {
}
public static void main(String[] args) throws Exception {
try
{
while(true)
{
System.out.println(new Foo().toString());
Thread.sleep(1000);
}
}
catch(Exception e)
{}
}
}
What I attempt to do is to make Foo.toString() returns 'test' by using the following agent.
public class InjectionAgent {
public InjectionAgent() {
}
public static void agentmain(String args, Instrumentation inst) throws Exception
{
System.out.println("agentmain Args:" + args);
new AgentBuilder.Default()
.type(ElementMatchers.named("Foo"))
.transform(new AgentBuilder.Transformer() {
#Override
public Builder<?> transform(Builder<?> arg0, TypeDescription arg1,
ClassLoader arg2, JavaModule arg3) {
return arg0.method(ElementMatchers.named("toString"))
.intercept(FixedValue.value("test"));
}
}).installOn(inst);
}
public static void premain(String args, Instrumentation inst) throws Exception
{
System.out.println("premain Args:" + args);
new AgentBuilder.Default()
.type(ElementMatchers.named("Foo"))
.transform(new AgentBuilder.Transformer() {
#Override
public Builder<?> transform(Builder<?> arg0, TypeDescription arg1,
ClassLoader arg2, JavaModule arg3) {
return arg0.method(ElementMatchers.named("toString"))
.intercept(FixedValue.value("test"));
}
}).installOn(inst);
}
}
I notice that, it was successful when I using -javaagent way, whereas attach way failed, here is code for attach.
public class Injection {
public Injection() {
}
public static void main(String[] args) throws AttachNotSupportedException, IOException, AgentLoadException, AgentInitializationException, InterruptedException {
VirtualMachine vm = null;
String agentjarpath = args[0];
vm = VirtualMachine.attach(args[1]);
vm.loadAgent(agentjarpath, "This is Args to the Agent.");
vm.detach();
}
}
I tried to add AgentBuilder.Listener.StreamWriting.toSystemOut() to the agent, after attaching, the output of TestEntry shows
[Byte Buddy] DISCOVERY Foo [sun.misc.Launcher$AppClassLoader#33909752, null, loaded=true]
[Byte Buddy] TRANSFORM Foo [sun.misc.Launcher$AppClassLoader#33909752, null, loaded=true]
[Byte Buddy] COMPLETE Foo [sun.misc.Launcher$AppClassLoader#33909752, null, loaded=true]
Foo#7f31245a
Foo#6d6f6e28
Foo#135fbaa4
Foo#45ee12a7
Foo#330bedb4
==================================Update=====================================
I defined a public method 'Bar' in Foo like this
public class Foo {
public String Bar()
{
return "Bar";
}
}
and then I was trying to make Foo.Bar() returns "modified" in the following way:
public static void agentmain(String args, Instrumentation inst) throws Exception
{
System.out.println("agentmain Args:" + args);
premain(args, inst);
new AgentBuilder.Default()
.with(RedefinitionStrategy.RETRANSFORMATION)
.disableClassFormatChanges()
.with(AgentBuilder.Listener.StreamWriting.toSystemOut())
.type(ElementMatchers.named("Foo"))
.transform(new AgentBuilder.Transformer() {
#Override
public Builder<?> transform(Builder<?> arg0, TypeDescription arg1,
ClassLoader arg2, JavaModule arg3) {
return arg0.visit(Advice.to(InjectionTemplate.class).on(ElementMatchers.named("Bar")));
}
})
.installOn(inst);
}
static class InjectionTemplate {
#Advice.OnMethodExit
static void exit(#Advice.Return String self) {
System.out.println(self.toString() + " " + self.getClass().toString());
self = new String("modified");
}
}
but I got this error:
java.lang.IllegalStateException: Cannot write to read-only parameter class java.lang.String at 1
any suggestions?
It does not seem like you are using redefinition for your agent. You can activate it using:
new AgentBuilder.Default()
.with(RedefinitionStrategy.RETRANSFORMATION)
.disableClassFormatChanges();
The last part is required on most JVMs (with the notable exception of the dynamic code evolution VM, a custom build of HotSpot). It tells Byte Buddy to not add fields or methods, what most VMs do not support.
In this case, it is no longer possible to invoke the original implementation of a method what is however not required for your FixedValue. Typically, users of Byte Buddy take advantage of Advice when creating an agent that applies dynamic transformations of classes.
I am learning to use robotium and I am trying to relaunch the application and do the same steps 5 time. I know to put for loop, but how do I relaunch application? I was using robotium recorder to do some of it, but it's easier to edit the script manually instead of recording again so I am trying to figure this out.
import com.robotium.solo.*;
import android.test.ActivityInstrumentationTestCase2;
#SuppressWarnings("rawtypes")
public class explore extends ActivityInstrumentationTestCase2 {
private Solo solo;
private static final String LAUNCHER_ACTIVITY_FULL_CLASSNAME = "com.application.calc.android.main.CGabboMainActivity";
private static Class<?> launcherActivityClass;
static{
try {
launcherActivityClass = Class.forName(LAUNCHER_ACTIVITY_FULL_CLASSNAME);
} catch (ClassNotFoundException e) {
throw new RuntimeException(e);
}
}
#SuppressWarnings("unchecked")
public explore() throws ClassNotFoundException {
super(launcherActivityClass);
}
public void setUp() throws Exception {
super.setUp();
solo = new Solo(getInstrumentation());
getActivity();
}
#Override
public void tearDown() throws Exception {
solo.finishOpenedActivities();
super.tearDown();
}
public void testRun() {
// Wait for activity: 'com.application.calc.android.main.CGabboMainActivity';
solo.waitForActivity("CGabboMainActivity", 2000);
// Sleep for 10211 milliseconds
solo.sleep(5000);
// Click on source_internet_radio
solo.clickOnWebElement(By.id("handle_name"));
//Sleep for 5697 milliseconds
solo.clickOnWebElement(By.id("source_help"));
solo.clickOnWebElement(By.id("nav_item_1"));
//solo.finishOpenedActivities();
//solo.waitForActivity("CGabboMainActivity", 2000);
//this.launchActivity(LAUNCHER_ACTIVITY_FULL_CLASSNAME, launcherActivityClass,null);
//solo.clickOnWebElement(By.xpath(".//*[#id='nav_panel_0']/div[1]/div/div[2]"));
//solo.sleep(15211);
//solo.clickOnWebElement(By.id("handle_name"));
}
}
I can suggest to create private helper method with test logic and 5 different test methods which call the helper. Before every test method there is setUp and after there is tearDown so your application will be restarted. Your class can look like:
import com.robotium.solo.*;
import android.test.ActivityInstrumentationTestCase2;
#SuppressWarnings("rawtypes")
public class explore extends ActivityInstrumentationTestCase2 {
private Solo solo;
private static final String LAUNCHER_ACTIVITY_FULL_CLASSNAME = "com.application.calc.android.main.CGabboMainActivity";
private static Class<?> launcherActivityClass;
static{
try {
launcherActivityClass = Class.forName(LAUNCHER_ACTIVITY_FULL_CLASSNAME);
} catch (ClassNotFoundException e) {
throw new RuntimeException(e);
}
}
#SuppressWarnings("unchecked")
public explore() throws ClassNotFoundException {
super(launcherActivityClass);
}
public void setUp() throws Exception {
super.setUp();
solo = new Solo(getInstrumentation());
getActivity();
}
#Override
public void tearDown() throws Exception {
solo.finishOpenedActivities();
super.tearDown();
}
public void testRun1() {
helper();
}
public void testRun2() {
helper();
}
public void testRun3() {
helper();
}
public void testRun4() {
helper();
}
public void testRun5() {
helper();
}
private void helper() {
// Wait for activity: 'com.application.calc.android.main.CGabboMainActivity';
solo.waitForActivity("CGabboMainActivity", 2000);
// Sleep for 10211 milliseconds
solo.sleep(5000);
// Click on source_internet_radio
solo.clickOnWebElement(By.id("handle_name"));
//Sleep for 5697 milliseconds
solo.clickOnWebElement(By.id("source_help"));
solo.clickOnWebElement(By.id("nav_item_1"));
//solo.finishOpenedActivities();
//solo.waitForActivity("CGabboMainActivity", 2000);
//this.launchActivity(LAUNCHER_ACTIVITY_FULL_CLASSNAME, launcherActivityClass,null);
//solo.clickOnWebElement(By.xpath(".//*[#id='nav_panel_0']/div[1]/div/div[2]"));
//solo.sleep(15211);
//solo.clickOnWebElement(By.id("handle_name"));
}
}
Another way is to create own test suite.
I am just trying to create a simple MINA server and client to evaluate. Here is my code.
public class Server {
private static final int PORT = 8080;
static class ServerHandler extends IoHandlerAdapter {
#Override
public void exceptionCaught(IoSession session, Throwable cause) throws Exception {
cause.printStackTrace();
}
#Override
public void sessionCreated(IoSession session) {
System.out.println("session is created");
session.write("Thank you");
}
#Override
public void sessionClosed(IoSession session) throws Exception {
System.out.println("session is closed.");
}
#Override
public void messageReceived(IoSession session, Object message) {
System.out.println("message=" + message);
session.write("Reply="+message);
}
}
/**
* #param args
*/
public static void main(String[] args) throws Exception {
SocketAcceptor acceptor = new NioSocketAcceptor();
acceptor.getFilterChain().addLast( "logger", new LoggingFilter() );
acceptor.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( Charset.forName( "UTF-8" ))));
acceptor.setHandler(new Server.ServerHandler());
acceptor.getSessionConfig().setReadBufferSize( 2048 );
acceptor.getSessionConfig().setIdleTime( IdleStatus.BOTH_IDLE, 10 );
acceptor.bind(new InetSocketAddress(PORT));
System.out.println("Listening on port " + PORT);
for (;;) {
Thread.sleep(3000);
}
}
}
public class Client {
private static final int PORT = 8080;
private IoSession session;
private ClientHandler handler;
public Client() {
super();
}
public void initialize() throws Exception {
handler = new ClientHandler();
NioSocketConnector connector = new NioSocketConnector();
connector.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new TextLineCodecFactory( Charset.forName( "UTF-8" ))));
connector.getFilterChain().addLast("logger", new LoggingFilter());
connector.setHandler(handler);
for (;;) {
try {
ConnectFuture future = connector.connect(new InetSocketAddress(PORT));
future.awaitUninterruptibly();
session = future.getSession();
break;
} catch (RuntimeIoException e) {
System.err.println("Failed to connect.");
e.printStackTrace();
Thread.sleep(5000);
}
}
if (session == null) {
throw new Exception("Unable to get session");
}
Sender sender = new Sender();
sender.start();
session.getCloseFuture().awaitUninterruptibly();
connector.dispose();
System.out.println("client is done.");
}
/**
* #param args
*/
public static void main(String[] args) throws Exception {
Client client = new Client();
client.initialize();
}
class Sender extends Thread {
#Override
public void run() {
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
handler.messageSent(session, "message");
}
}
class ClientHandler extends IoHandlerAdapter {
#Override
public void sessionOpened(IoSession session) {
}
#Override
public void messageSent(IoSession session, Object message) {
System.out.println("message sending=" + message);
session.write(message);
}
#Override
public void messageReceived(IoSession session, Object message) {
System.out.println("message receiving "+ message);
}
#Override
public void exceptionCaught(IoSession session, Throwable cause) {
cause.printStackTrace();
}
}
}
When I execute this code, the Client seems to keep sending a message instead of stopping after it sends. It looks to me that there is a recursive call in underlying MINA code. I know that I am doing something wrong.
Can somebody tell me how to fix this?
Thanks.
Try to initialize and start your sender and use the session within sessionOpened (ClientHandler)
