We have an issue with queueable apex. Great if you could help on this?
Their requirement is to sync Salesforce object to external system.
Currently there is a trigger that executes an queueable apex job that do the call-out and update lead at the end.
This works perfectly during our testing. Also we have bulk tested today. However randomly we get the following error.
I will share a sample code.
Error:
1: Lead Id: XXXXXXXXXXXXXXXXXX Error : System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling outType: System.CalloutException
Cause: null
Message: You have uncommitted work pending. Please commit or rollback before calling out
We only do updates at the end of queue execution. This works perfectly when we test for single or bulk load. Issue is intermittent.

If you override buildRequestBody in a multipart request you effectively disable its functionality...
All of that code is incorrect and shouldn't be there. Multipart will work for large files by default.
In our current framework we are taking screenshots onTestFailure. And now we have implemented 'IRetryAnalyzer' using which are re-running the failed tests.
Here when the test fails for the first time, it is taking the screen shot and keeping it in a folder which indicates 'Failed Test', which may get passed in the next attempt.
When we submit final Automation report, we need to submit screenshots also. In Screenshots folder, currently passed (after re-running) test images are also attached.
Can we take a screenshot only when the Test has failed Even After Re-running by ignoring the previous test fails.
Please suggest if there is any other alternative.
Below is the code for Retry
#Override
public boolean retry(ITestResult result) {
boolean iFlag=false;
String resultString = result.getThrowable().toString();
//Checking for specific reason of failure
if (resultString.contains("NoSuchElementException") || resultString.contains("TimeoutException") ) {
if (retryCount < maxRetryCount) {
System.out.println("Retrying " + result.getName()+ " test for the "+ (retryCount + 1) + " time(s).");
retryCount++;
iFlag=true;
}
} else {
//making retryCount and maxRetryCount equal
retryCount=0;
maxRetryCount=0;
iFlag=false;
}
return iFlag;
}
Below is the code for On Test failure
private static int retryCount=0;
private static int maxRetryCount=1;
#Override
public void onTestFailure(ITestResult result) {
System.out.println("***** Error "+result.getName()+" test has failed *****");
String methodName=result.getName().toString().trim();
//takeScreenShot(methodName);
driver=TestBase.getDriver();
if( driver != null && retryCount == maxRetryCount) {
takeScreenShot(driver, methodName);
}
}
Try to put both onTestFailure/AfterMethod and retry methods in same class like Retry or any suitable name. And there you can define your methods as:
private static int retryCount = 0;
private static int maxRetryCount = 2;
#AfterMethod
public void tearDown(ITestResult result) throws IOException {
String methodname = result.getName();
WebDriver augmentedDriver = new Augmenter().augment(driver);
try {
if (driver != null
&& ((RemoteWebDriver) driver).getSessionId() != null
&& !result.isSuccess() && retryCount == maxRetryCount) {
File scrFile = ((TakesScreenshot) augmentedDriver)
.getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile, new File(("./test-output/archive/"
+ "screenshots/" + methodname + "_" + System.currentTimeMillis() + ".png")));
}
} catch (Exception e) {
e.printStackTrace();
} finally {
driver.quit();
}
}
#Override
public boolean retry(ITestResult result) {
boolean res = false;
try {
if (result.getThrowable().toString()
.contains("NoSuchElementException")) {
if (retryCount < maxRetryCount) {
retryCount++;
res = true;
} else if (retryCount == maxRetryCount) {
retryCount = 0;
res = false;
}
} else {
retryCount = 0;
}
return res;
} catch (Exception e) {
return false;

I have problem with loading image from database to jsp view. It looks like action are execute but stop in middle.
I log when execute() method start and when its end. In log file i can see start this method but there are no end.
I have action:
public class ShowImageAction extends BaseAction {
private static final long serialVersionUID = 1L;
private static final Log LOG = LogFactory.getLog(ShowImageAction.class);
private int id;
public String execute() {
LOG.info("Enter execute()");
MessageBean messageBean = (MessageBean) sessionParameters
.get(SessionParameters.BANNER_EDIT);
IFiles filesEJB = EJBLocator.getFiles();
if (messageBean != null) {
id = messageBean.getBannerId();
}
FileBean file = filesEJB.file(id);
LOG.info("Id = " + id);
if (file != null) {
byte[] bytes = null;
try {
LOG.info("File: name = " + file.getName() + ". type = "
+ file.getType());
if (file.getImage() != null) {
bytes = FileUtils.readFileToByteArray(file.getImage());
HttpServletResponse response = ServletActionContext
.getResponse();
response.setContentType(file.getType());
OutputStream out = response.getOutputStream();
out.write(bytes);
out.close();
} else {
LOG.info("execute(): Nie udało się pobrać pliku z bazy danych!");
}
} catch (IOException e) {
LOG.error(e);
}
} else {
LOG.info("execute(): Nie udało się pobrać pliku z bazy danych!");
}

return NONE;
}
jsp:
<div class="OneFilteringRow">

<img src="/ebok-bm/ShowImageAction" alt="Podgląd banera" />
</div>
struts.xml
<action name="ShowImageAction"
class="pl.bm.action.content.ShowImageAction">
</action>
Problem was in:
FileBean file = filesEJB.file(id);
I get bytes from database and try to save it to tmpFile. Now I get bytes and writes them to a temporary file and immediately transmit it to the action and everything is ok.
Now I have:
FileBean file = filesEJB.file(id);
LOG.info("Id = " + id);
if (file != null) {
byte[] bytes = null;
try {
LOG.info("File: name = " + file.getName() + ". type = "
+ file.getType());
if (file.getImage() != null) {
**bytes = file.getImage();**
HttpServletResponse response = ServletActionContext
.getResponse();
response.setContentType(file.getType());
OutputStream out = response.getOutputStream();
out.write(bytes);
out.close();
} else {
LOG.info("execute(): Nie udało się pobrać pliku z bazy danych!");
}
} catch (IOException e) {
LOG.error(e);
}
}
Switch to your own result implements Result class and write output here.Other in struts.xmlaction result type specified own with approx mate parameters.
refer:generate own image as action result
