I'm unable to figure out why is this code failing, I browsed through Applitools tutorials and I can't figure out what is happening here.
This is the exception being thrown:
com.applitools.eyes.EyesException: eyes.openBase() failed
at com.applitools.eyes.EyesBase.openBase(EyesBase.java:1037)
at com.applitools.eyes.selenium.SeleniumEyes.open(SeleniumEyes.java:246)

at com.applitools.eyes.selenium.Eyes.open(Eyes.java:1374)
at BaseTests.validateWindow(BaseTests.java:49)
at SearchTests.testSearchByFullTitle(SearchTests.java:11)
This is SearchTests:
import org.junit.Test;
public class SearchTests extends BaseTests {
#Test
public void testSearchByFullTitle(){
String title = "Agile Testing";
page.search(title);
validateWindow();
}
}
Validate window method:
public void validateWindow(){
eyes.open(driver, "Automation Bookstore", "neka metoda npr: "+
Thread.currentThread().getStackTrace()[2].getMethodName());
eyes.checkWindow();
eyes.close();
}
and the class throwing the exception:
protected void openBase() throws EyesException {
openLogger();
int retry = 0;
do {
try {
if (isDisabled) {
logger.verbose("Ignored");
return;
}
sessionEventHandlers.testStarted(getAUTSessionId());
validateApiKey();
logOpenBase();
validateSessionOpen();
initProviders();
this.isViewportSizeSet = false;
sessionEventHandlers.initStarted();
beforeOpen();
RectangleSize viewportSize = getViewportSizeForOpen();
viewportSizeHandler.set(viewportSize);
try {
if (viewportSize != null) {
ensureRunningSession();
}
} catch (Exception e) {
GeneralUtils.logExceptionStackTrace(logger, e);
retry++;
continue;
}
this.validationId = -1;
isOpen = true;
afterOpen();
return;
} catch (EyesException e) {
logger.log(e.getMessage());
logger.getLogHandler().close();
throw e;
}
} while (MAX_ITERATION > retry);
throw new EyesException("eyes.openBase() failed");
}
After some debugging, I found that I had a typo in my API key. After fixing that, works as expected.
In my case, the same issue was caused by using null as a value for the testName parameter.
I didn't understand it from the beginning, cause I relied on the javadoc for the open function:
/**
* Starts a test.
*
* #param driver The web driver that controls the browser hosting the application under test.
* #param appName The name of the application under test.
* #param testName The test name. (i.e., the visible part of the document's body) or {#code null} to use the current window's viewport.
* #return A wrapped WebDriver which enables SeleniumEyes trigger recording and frame handling.
*/
public WebDriver open(WebDriver driver, String appName, String testName) {
RectangleSize viewportSize = SeleniumEyes.getViewportSize(driver);
this.configuration.setAppName(appName);
this.configuration.setTestName(testName);
this.configuration.setViewportSize(viewportSize);
return open(driver);
}

I am running dotnet core 2.* and as the title mentions I have trouble getting my try catch to work when calling from API. And before anyone comments I am also running middle-ware to catch any exceptions. It too doesn't perform as expected

// Add Model View Controller Support
services.AddMvc( config =>
config.Filters.Add(typeof (CustomExceptionFilter))

UPDATE: After playing around with it I noticed that even though my program throws the exception, if I press continue the API controller then handles it as if the exception was never thrown (as in it catches it and does what I want). So I turned off the break on Exception setting, this fixed it in debugger mode. However this the break doesn't seem to be an issue when I build/publish the program. This makes me think it is definitely a issue with visual studio itself rather than the code.
When you set ExceptionHandled to true that means you have handled the exception and there is kind of no error anymore. So try to set it to false.
context.ExceptionHandled = false;
I agree it looks a bit confusing, but should do the trick you need.
Relevant notes:
For those who deal with different MVC and API controller make sure you implemented appropriate IExceptionFilter as there are two of them - System.Web.Mvc.IExceptionFilter (for MVC) and System.Web.Http.Filters.IExceptionFilter (for API).
There is a nice article about Error Handling and ExceptionFilter Dependency Injection for ASP.NET Core APIs you could use as a guide for implementing exception filters.
Also have a look at documentation: Filters in ASP.NET Core (note selector above the left page menu to select ASP.NET Core 1.0, ASP.NET Core 1.1,ASP.NET Core 2.0, or ASP.NET Core 2.1 RC1). It has many important notes and explanations why it works as it does.
I am using junit request in jmeter to get the performance result of the scripts. When I run the script it is not giving any error however it is not giving the results.

I recently faced the same issue. I checked below two boxes in the Junit Request page on Jmeter UI.
Append assertion errors
Append runtime exception
After this when I executed the test again, I found the error in the "View Results Tree" listener under Response Message field.
Hope this helps.
Please try making all private variables as public. It may happen that JMeter is not able access those.
Also, refer console on JMeter, it should show you errors/exceptions.
I am trying to implement jsr-179 APi into Nokia Symbian phone for periodic location update using setLocationListener through J2me. In emulator it is working fine. While I installed Midlet on the device nokia 5230, it is given NullPointerException and the application is automatically terminating. What might be possible causes?
Below is my class, I am instantiating object for this class on a form in netbeans
class MovementTracker implements LocationListener {
LocationProvider provider;
Location lastValidLocation;
UpdateHandler handler;
boolean done;
public MovementTracker() throws LocationException
{
done = false;
handler = new UpdateHandler();
new Thread(handler).start();
//Defining Criteria for Location Provider
/*
Criteria cr = new Criteria();
cr.setHorizontalAccuracy(500);
*/
//you can place cr inside getInstance
provider = LocationProvider.getInstance(null);
//listener,interval,timeout,int maxAge
//Passing -1 selects default interval
// provider.setLocationListener(MovementTracker.this, -1, -1, -1);
provider.setLocationListener(MovementTracker.this, -1, 30000, 30000);
}
public void locationUpdated(LocationProvider provider, Location location)
{
handler.handleUpdate(location);
batteryLevel = System.getProperty("com.nokia.mid.batterylevel");
sn = System.getProperty("com.nokia.mid.networksignal");
localTime = System.currentTimeMillis();
Send_Location();
}
public void providerStateChanged(LocationProvider provider, int newState)
{
}
class UpdateHandler implements Runnable
{
private Location updatedLocation = null;
// The run method performs the actual processing of the location
public void run()
{
Location locationToBeHandled = null;
while (!done)
{
synchronized(this)
{
if (updatedLocation == null)
{
try
{
wait();
}
catch (Exception e)
{
// Handle interruption
}
}
locationToBeHandled = updatedLocation;
updatedLocation = null;
}
// The benefit of the MessageListener is here.
// This thread could via similar triggers be
// handling other kind of events as well in
// addition to just receiving the location updates.
if (locationToBeHandled != null)
processUpdate(locationToBeHandled);
}
try
{
Thread.sleep(10000); //Sleeps for 10 sec & then sends the data
}
catch (InterruptedException ex)
{
}
}
public synchronized void handleUpdate(Location update)
{
updatedLocation = update;
notify();
}
private void processUpdate(Location update)
{
latitude = update.getQualifiedCoordinates().getLatitude();
longitude = update.getQualifiedCoordinates().getLongitude();
altitude = update.getQualifiedCoordinates().getAltitude();
}
}
}
public MovementTracker() throws LocationException
...
I have not written any code for handling LocationException.
No code is very dangerous practice, just search the web for something like "java swallow exceptions".
It is quite possible that because of implementation specifics Nokia throws LocationException where emulator does not throw it. Since you don't handle exception this may indeed crash you midlet at Nokia - and you wouldn't know the reason for that because, again, you have written no code to handle it.
How can I catch that exception?
The simplest thing you can do is to display an Alert with exception message and exit the midlet after user reads and dismisses alert
I wrote an IHttpModule that compress my respone using gzip (I return a lot of data) in order to reduce response size.
It is working great as long as the web service doesn't throws an exception.
In case exception is thrown, the exception gzipped but the Content-encoding header is disappear and the client doesn't know to read the exception.
How can I solve this? Why the header is missing? I need to get the exception in the client.
Here is the module:
public class JsonCompressionModule : IHttpModule
{
public JsonCompressionModule()
{
}
public void Dispose()
{
}
public void Init(HttpApplication app)
{
app.BeginRequest += new EventHandler(Compress);
}
private void Compress(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
HttpRequest request = app.Request;
HttpResponse response = app.Response;
try
{
//Ajax Web Service request is always starts with application/json
if (request.ContentType.ToLower(CultureInfo.InvariantCulture).StartsWith("application/json"))
{
//User may be using an older version of IE which does not support compression, so skip those
if (!((request.Browser.IsBrowser("IE")) && (request.Browser.MajorVersion <= 6)))
{
string acceptEncoding = request.Headers["Accept-Encoding"];
if (!string.IsNullOrEmpty(acceptEncoding))
{
acceptEncoding = acceptEncoding.ToLower(CultureInfo.InvariantCulture);
if (acceptEncoding.Contains("gzip"))
{
response.AddHeader("Content-encoding", "gzip");
response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
}
else if (acceptEncoding.Contains("deflate"))
{
response.AddHeader("Content-encoding", "deflate");
response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
}
}
}
}
}
catch (Exception ex)
{
int i = 4;
}
}
}
Here is the web service:
[WebMethod]
public void DoSomething()
{
throw new Exception("This message get currupted on the client because the client doesn't know it gzipped.");
}
I appriciate any help.
Thanks!
Even though it's been a while since you posted this question, I just had the same issue and here's how I fixed it:
In the Init() method, add a handler for the Error event
app.Error += new EventHandler(app_Error);
In the handler, remove Content-Type from the Response headers and set the Response.Filter property to null.
void app_Error(object sender, EventArgs e)
{
HttpApplication httpApp = (HttpApplication)sender;
HttpContext ctx = HttpContext.Current;
string encodingValue = httpApp.Response.Headers["Content-Encoding"];
if (encodingValue == "gzip" || encodingValue == "deflate")
{
httpApp.Response.Headers.Remove("Content-Encoding");
httpApp.Response.Filter = null;
}
}
Maybe there's a more elegant way to do this but did the trick for me.
Is there any api for viewing html content from w/in your blackberry application? To be clear, I don't mean launching the browser on top of my app to view a page. But rather rendering the page w/in my app.
Yes. Check out the net.rim.device.api.browser.field package or the Blackberry Browser section of application integration.
Everything sort of finishes here:
Field field = browserContent.getDisplayableContent();
See:
JDE 4.0.0 API for the package
RIM app integration guide
Signed only api, as usual.
//BrowserField is available for 4.5 OS. RIM provide sample app for BrowserField Demo. you can find the sample example and run it.
