I just tried out the example of the Jersey tutorial which concerns AsyncResponse and can be found here: http://jersey.java.net/apidocs/snapshot/jersey/javax/ws/rs/container/AsyncResponse.html
It does not seem to work. Even the example throws an exception when executed in a simple unit test:
public class AsyncTest extends JerseyTest {
#Override
protected Application configure() {
return new ResourceConfig(MyAsync.class)
}
#Path("/async")
public static class MyAsync {
#GET
public void asyncGet(#Suspended final AsyncResponse asyncResponse) {
new Thread(new Runnable() {
#Override
public void run() {
String result = veryExpensiveOperation();
asyncResponse.resume(result);
}
private String veryExpensiveOperation() {
return "bla";
}
}).start();
}
}
#Test
public void testConvertWordToPdf() throws Exception {
String result = target().path("async").request().async().get().get(String.class);
}
}
Can somebody tell me what I am doing wrong? Thanks for any answer!
Update: I even tried the official example that can be found at http://search.maven.org/#artifactdetails|org.glassfish.jersey.examples|server-async-standalone-webapp|2.1|war and I get the same exception. The example works, if I make sure the AsyncResponse responds before the method returns. The stack trace I get:

Btw, I tested this testcase in Grizzly container. It is not supported in InMemory container as the container does not implement suspend operation on the ContainerResponseWriter. InMemoryResponseWriter should throw an UnsupportedOperationException instead of returning false. This sounds like a Jersey bug.
#Test
public void testConvertWordToPdf() throws Exception {
String result = target().path("async").request().async().get().get().readEntity(String.class);
assertEquals("bla", result);
}
Here is my POM dependency:

I am using Junit4 for testing external java class.
I want to Mock the below line of code
MySearch mySearch = MyCache.getData(new MyAlgorithm(keyword.trim()), MySearch.class);
I tried like this
#RunWith(PowerMockRunner.class)
#PrepareForTest({MyCache.class, MyAlgorithm.class})
public class Test {
#BeforeClass
public static void setUpBeforeClass() throws Exception {
PowerMockito.mockStatic(MyCache.class);
MyAlgorithm alg = Mockito.mock(MyAlgorithm.class);
PowerMockito.whenNew(MyAlgorithm.class).withArguments("ABC").thenReturn(alg);
MySearch mySearch = Mockito.mock(MySearch.class);
PowerMockito.when(MyCache.getData(alg,MySearch.class)).thenReturn(mySearch);
//...
}
}
But still i am getting this error "java.lang.ExceptionInInitializerError"

Make sure you have at least one test method. Something like:
#org.junit.Test
public void testMethod() {
}
I am trying to Mock an application using an Android Platform. Many class use super-classe which are part of the Android classes which are unaccessible to my Unit test, this is why I thought using JMockit would solve my problem. Note that I am using also
org.mockito.Mock and org.powermock.
Here's a simple test I am trying to do in a class with Mockup:
// ---------------------------------------
public class Bar {
public void bar() {
System.out.println("Bar#bar()");
}
public void doSomething() {
System.out.println("do something!");
}
}
public class BarChild extends Bar {
public void BarChild() {
System.out.println("BarChild#bar()");
}
public void Call1() {
doSomething();
}
}
// ---------------------------------------
#Test
public void testMockUp() throws Exception {
new MockUp<Bar>() {
#mockit.Mock
public void doSomething(){
System.out.println("do something else");
}
};
BarChild obj1 = new BarChild();
obj1.Call1();
}
// ---------------------------------------
This doesn't work. It generate the following error:
java.lang.NoSuchFieldError: $MMB at

I am getting the feeling that there is a dependency missing.
Any help?
I ran into a similar issue with many tests in my project, and for me it was simply upgrading the jmockit dependency from version 1.23 to 1.28 in my gradle build script, try upgrading it might solve your problem also
Below is the code for my attempt to run aggregates on hazelcast using Hazelcast Client. The first aggregate works out just fine, but the 2nd one throws an java.io.NotSerializableException: co.near.hazelcast.AggregateExperiment
My code:
public class AggregateExperiment {
public void runTest(){
ClientConfig clientConfig = new ClientConfig();
clientConfig.addAddress("127.0.0.1:5701");
clientConfig.setClassLoader(this.getClass().getClassLoader());
HazelcastInstance client = HazelcastClient.newHazelcastClient(clientConfig);
IMap<String, Integer> map = client.getMap("customers");
Supplier<String, Integer, Integer> supplier = Supplier.all();
// Choose the average aggregation
Aggregation<String, Integer, Integer> aggregation = Aggregations.integerAvg();
int average = map.aggregate(supplier, aggregation);
System.out.println("Average of inputs = "+average);
supplier = Supplier.fromKeyPredicate(new MyKeyPredicate());
// Choose the sum aggregation
aggregation = Aggregations.integerSum();
average = map.aggregate(supplier, aggregation );
System.out.println("Average of inputs = "+average);
}
public class MyKeyPredicate implements KeyPredicate<String> {
public boolean evaluate(String key) {
return Integer.parseInt(key) % 4 == 0;
}
}
}
Error messages :

Any help is much appreciated. Thanks
Instances of the inner class MyKeyPredicate contain an implicit reference to parent AggregateExperiment instance. This makes MyKeyPredicate not serializable. You should make MyKeyPredicate static:
public static class MyKeyPredicate implements KeyPredicate<String> {

Hazelcast as of now does not support distributed classloading which would be needed for the code above to work properly.
An issue is github is already opened for the same https://github.com/hazelcast/hazelcast/issues/7394
For now, those who really want to use Hazelcast in this manner can explore https://github.com/serkan-ozal/hermgen as well
yesterday my test works ok, bust i want to use testng and then appeared a problem.
My main class leadTest:
public class leadTest {
WebDriver driver;
#Test
public void f() {
..
...
...
/*------------------------Go to leads page-------------------------------*/
LeadsPage ldsP = new LeadsPage(driver);
dbp.gotoLeadsPage();
ldsP.findLeadByName("nameToFind");
}
#BeforeClass
public void beforeClass() {
driver = new FirefoxDriver();
driver.get("http://getbase.com");
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
}
and my class LeadsPage:
public class LeadsPage {
WebDriver driver;
String expStatus = "new";
#FindBy(id="leads-new")
WebElement addLead;
#FindBy(className = "lead-status")
WebElement UserStatus;
public void addNewLead(){
addLead.click();
}
public void checkUsrStat(){
String stat = UserStatus.getText().toLowerCase();
Assert.assertEquals(stat, expStatus.toLowerCase());
}
public void findLeadByName(String leadName){
driver.findElement(By.partialLinkText(leadName)).click();
}
public LeadsPage(WebDriver driver){
PageFactory.initElements(driver, this);
}
I have problem with this part from above:
public void findLeadByName(String leadName){
driver.findElement(By.partialLinkText(leadName)).click();
}
I have error

When i use
#FindBy(partialLinkText="nameToFind")
WebElement ntf;
and
ntf.click();
its works, but i cant do that, becouse in place nameToFind will be variable.
And i dont know what is wrong... Please help me
Driver variable not initialized: you try to call findElement() method on a null object.
One way to confirm that is to print the driver value:
System.out.println("driver=" + driver); just before the exception is thrown
public void findLeadByName(String leadName){
System.out.println("driver=" + driver);
driver.findElement(By.partialLinkText(leadName)).click();
}
also i am noticing ,
LeadsPage ldsP = new LeadsPage(driver);
dbp.gotoLeadsPage();
ldsP.findLeadByName("nameToFind");
gotoLeadsPage(); and findLeadByName(); both functions are in same class LeadsPage but using different objects dbp and ldsp
May be below changes will work.
in LeadsPage class change your findLeadByName(); function as follows,
public void findLeadByName(WebDriver driver, String leadName){
this.driver.findElement(By.partialLinkText(leadName)).click();
}
and in your class leadTest call function findLeadByName() as follows,
LeadsPage ldsP = new LeadsPage(driver);
ldsP.findLeadByName(driver ,"nameToFind");
I am using CSV reader to fetch the data from and using this data in a test function using DataProvider.
TestNG Method
#Test(dataProvider = "regCSVData", dataProviderClass = LoginData.class)
public void testLoginUsingCSVFile(LoginData loginData){
driver.get(appURL);
Login login = PageFactory.initElements(driver, Login.class);
login.loginToFwbm(loginData);
}
LoginData Class
#DataProvider(name = "regCSVData")
public static Object[][] getCSVData() throws IOException {
CSVReader csvReader = new CSVReader(new FileReader(
LoginData.class.getResource("/regdata.csv").getPath()));
List<String[]>dataList = csvReader.readAll();
Object[][]data = new Object[dataList.size()][1];
List<LoginData> logList = new ArrayList<LoginData>();
for (String[] strArray:dataList){
LoginData loginData = new LoginData();
loginData.setUserName(strArray[0].trim());
loginData.setPassword(strArray[1].trim());
logList.add(loginData);
}
for (int i=0; i<data.length;i++){
for(int j=0;j<data[i].length;j++){
data[i][j] = logList.get(i);
}
}
csvReader.close();
return data;
}

You have to add the file to the classPath in your "run configuration". Then the file can be loaded using getRessource();
The best way to use QAF. In QAF, you don't need to provide implementation for parse data provider file. It is very much easy for you to use it.
You can refer documentation from QAF Data Driven
