What is the use of System.getProperty() while taking Screenshot in Selenium? - selenium-webdriver

I'm running a program for adding screenshot in extent report automatically using selenium. Program is running perfectly,but I want to know the meaning of System.getProperty line in below program .
public class SST
{
public static String getScreenshot(WebDriver driver)
{
TakesScreenshot ts=(TakesScreenshot) driver;
File src=ts.getScreenshotAs(OutputType.FILE);
String path = System.getProperty("user.dir")+"/Screenshot/"+System.currentTimeMillis()+".png";
File destination=new File(path);
try
{
FileUtils.copyFile(src, destination);
} catch (IOException e)
{
System.out.println("Capture Failed "+e.getMessage());
}
return path;
}
}

It is getting the user home directory, for example, C:\Users\user10796675.

IllegalStateException when running a Selenium test

I'm getting an IllegalStateException thrown when running the following code:
package newprojectss;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class Tours {
public static void main(String[] args) {
// declaration and instantiation of objects/variables
System.setProperty("webdriver.chrome.driver","C:\\selenium-2.25.0\\chromedriver_win32");
WebDriver driver = new ChromeDriver();
String baseUrl = "http://demo.guru99.com/test/newtours/";
String expectedTitle = "Welcome: Mercury Tours";
String actualTitle = "";
// launch Fire fox and direct it to the Base URL
driver.get(baseUrl);
// get the actual value of the title
actualTitle = driver.getTitle();
/*
* compare the actual title of the page with the expected one and print
* the result as "Passed" or "Failed"
*/
if (actualTitle.contentEquals(expectedTitle)){
System.out.println("Test Passed!");
} else {
System.out.println("Test Failed");
}
//close Firefox
driver.close();
}
}
What can cause the problem?
illegalstateexception occurs because the chrome driver is not set properly
System.setProperty("webdriver.chrome.driver","C:\\selenium-2.25.0\\chromedriver_win32")
Chrome driver path doesn't point till chromedriver.exe file
Unzip your driver folder and point the location till chromedriver.exe
Eg: C://Users//username//Desktop//chromedriver.exe

Have a problem when run jbmp sample in eclipse

Coud anybody help me fix my problem? When I tried to run jbpm sample in eclipse. This is code:
public class ProcessMain {
public static void main(String[] args) {
KieServices ks = KieServices.Factory.get();
KieContainer kContainer = ks.getKieClasspathContainer();
KieBase kbase = kContainer.getKieBase("kbase");
RuntimeManager manager = createRuntimeManager(kbase);
RuntimeEngine engine = manager.getRuntimeEngine(null);
KieSession ksession = engine.getKieSession();
ksession.startProcess("com.sample.bpmn.hello");
manager.disposeRuntimeEngine(engine);
System.exit(0);
}
private static RuntimeManager createRuntimeManager(KieBase kbase) {
JBPMHelper.startH2Server();
JBPMHelper.setupDataSource();
EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa");
RuntimeEnvironmentBuilder builder = RuntimeEnvironmentBuilder.Factory.get()
.newDefaultBuilder().entityManagerFactory(emf)
.knowledgeBase(kbase);
return RuntimeManagerFactory.Factory.get()
.newSingletonRuntimeManager(builder.get(), "com.sample:example:1.0");
}
}
Then, this is error in console window:

Selenium-Extent_Reports: Not able to view the failure screenshots on other Computer/Machine

-Failure Screenshot are visible in Extent_Reports on my local machine. But not able to view the failure screenshot in Extent_Reports on other Computer/Machine.
-When i trigger build from Jenkins, After build successful, Sending email to:Recipient List
To Capture Screenshot
public String captureScreen(String fileName) {
if(fileName =="") {
fileName="Screenshot"; }
File destFile=null;
Calendar calendar =Calendar.getInstance() ;
SimpleDateFormat formater= new SimpleDateFormat("dd_MM_yyy_hh_mm_ss");
File srcFile=((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
try {
String reportDirectory = "/src/main/java/com/test/automation/Demo/screenshot/";
//String reportDirectory= new File(System.getProperty("user.dir")).getAbsolutePath()+"./src/main/java/com/test/automation/Demo/screenshot/";
destFile= new File((String)reportDirectory + fileName +"-" + formater.format(calendar.getTime())+ ".png");
FileUtils.copyFile(srcFile,destFile );
//This will help us to link screen shot in Extent report
Reporter.log("<a href='"+destFile+ "'><img src='" +destFile+"' height='100' width='100'/></a>");
//Reporter.log("<a href='"+destFile.getAbsolutePath()+ "'><img src='" +destFile.getAbsolutePath()+"' height='100' width='100'/></a>");
}
catch(IOException e) {
e.printStackTrace();
}
return destFile.toString();
}
For generating Extent reports with screenshots for Failure test cases
public void getresult(ITestResult result) {
if(result.getStatus()==ITestResult.FAILURE)
{
test.log(LogStatus.ERROR, result.getName()+" Test case FAILED due to below issues: "+result.getThrowable());
String screen = captureScreen("");
test.log(LogStatus.FAIL," Failure Screenshot : "+ test.addScreenCapture(screen));
}}
If You're using remoteWebDriver than it must be augmented before you can use the screenshot capability. Did You try to
WebDriver driver = new RemoteWebDriver();
driver = new Augmenter().augment(driver);
// or for mobile driver
androidDriver.setFileDetector(new LocalFileDetector());
//this is needed when using remoteDriver
Here is how I take screenshot for ExtentReport
File scrFile = driver.getScreenshotAs(OutputType.FILE);
String dest = System.getProperty("user.dir") + "/resources/screenshots/" + dataMethod.getAndroidDriver().getSessionId() + ".png";
File destination = new File(dest);
try {
FileUtils.copyFile(scrFile, destination);
// this is just utility which takes screenshot and copy it to desired destination
dataMethod.setScreenshotPath(destination.getAbsolutePath());
} catch (IOException e) {
e.printStackTrace();
}
And on code failure:
#Override
public synchronized void onTestFailure(ITestResult result) {
setTestEndTime(result);
ExtentTest extentTest = methodData.getExtentTest();
extentTest.addScreenCaptureFromPath(methodData.getScreenshotPath());
}
Hope this will help.
I didn't used Extent reports, i have my own implementation for reports. But i am expecting is there is issue with src
<img src='" +destFile+"' height='100' width='100'/></a>");
Here, destFile brings location of image or screenshot which is related to your machine. the same should not be works for others. We have to use relative path, see this
https://www.w3schools.com/html/html_filepaths.asp
And also make sure that when sharing reports, it should contains all requires files and folders also.
Normally, the issue happens as the local files are not allowed to be loaded. So even we put relative or absolute path, that seems not work for many cases.
So I try to take base64screenshot instead, and it displays quite good in Extent Report.
To have the screenshot in folder report, just need to take screenshot as usual.
public static String getBase64Screenshot(WebDriver driver, String screenshotName) throws IOException {
String encodedBase64 = null;
FileInputStream fileInputStream = null;
TakesScreenshot screenshot = (TakesScreenshot) driver;
File source = screenshot.getScreenshotAs(OutputType.FILE);
String destination = windowsPath + "\\FailedTestsScreenshots\\"+screenshotName+timeStamp+".png";
File finalDestination = new File(destination);
FileUtils.copyFile(source, finalDestination);
try {
fileInputStream =new FileInputStream(finalDestination);
byte[] bytes =new byte[(int)finalDestination.length()];
fileInputStream.read(bytes);
encodedBase64 = new String(Base64.encodeBase64(bytes));
}catch (FileNotFoundException e){
e.printStackTrace();
}
return encodedBase64;
}
Call it in failure cases:
public synchronized void onTestFailure(ITestResult result) {
System.out.println("==="+methodDes + "=== failed!");
try {
WebDriver driver = (WebDriver) result.getTestContext().getAttribute("driver");
String base64Screenshot = ExtentManager.getBase64Screenshot(driver, result.getName());
MediaEntityModelProvider mediaModel = MediaEntityBuilder.createScreenCaptureFromBase64String(base64Screenshot).build();
test.get().fail("image:", mediaModel);
} catch (IOException e) {
e.printStackTrace();
}
test.get().fail(result.getThrowable().getMessage());
}

How can I e-mail a .csv file in Codename One?

In my app, I create a file with a comma-separated array by writing to an OutputStream. Then I want to be able to share this by e-mail so a user can get the data. This is the code I use to create the file:
public String getLogFile(String logName) {
String path = FileSystemStorage.getInstance().getAppHomePath() + "exp " + logName + ".csv";
Set<Long> keys;
OutputStream os = null;
try {
os = FileSystemStorage.getInstance().openOutputStream(path);
Hashtable<Long, Integer> log = (Hashtable<Long, Integer>) dataStorage
.readObject(logName);
keys = log.keySet();
for (Long key : keys) {
String outString = (key + "," + log.get(key) + "\n");
System.out.println(outString);
byte[] buffer = outString.getBytes();
os.write(buffer);
}
} catch (IOException e) {
AnalyticsService.sendCrashReport(e, "Error writing log", false);
e.printStackTrace();
} finally {
try {
os.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
return path;
}
Then, I've created a button that when pressed passes the path of the file to share. I've tried to use MIME types such as "text/plain" and "text/comma-separated-values", but that causes errors. Here is the code executed when the button is pressed.
public void exportLog(String logName) {
String path = dataBuffer.getLogFile(logName);
EmailShare email = new EmailShare();
// email.share("Here is your log.", path, "text/plain");
email.share("Here is your log.", path, "text/comma-separated-values");
}
When pressed (in the simulator). I get this stack after selecting the dummy e-mail contact to send to:

The EmailShare class expects a path to an image file not an arbitrary file as its second argument so loading that fails.
The Message class is better suited for that indeed. You can also use the cloud send option which won't launch the native email app. E.g. the Log class includes that ability directly thru the Log.sendLog API.
It looks like the Messages class is better suited for this task, and should allow attachments, etc.

Tomcat executor with runnable while(true) loop is only run once. Why?

I am trying to implement a javax.mail.event.MessageCountListener in Tomcat. When I start the application the contextInitialized method seems to run and the mailbox is read. However, I see the log message "Idling" only once. I would expect that it would idle constantly and invoke the AnalyzerService() when an email is received or deleted.
Update: Found that the idle() method is not returning. It runs untill com.sun.mail.iap.ResponseInputStream.readResponse(ByteArray ba) method where it runs into a while loop where it never gets out.
Am I misusing the idle() method for something I should not do? Is this a bug in com.sun.mail.iap package?
The AnalyzerContextListener.java:
import com.sun.mail.imap.IMAPStore;
import java.util.Properties;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import javax.mail.Folder;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.event.MessageCountListener;
import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
public class AnalyzerContextListener implements ServletContextListener {
private ExecutorService executorService;
private final String username = "myemail#gmail.com";
private final String password = "mypassword";
private final String mailhost = "imap.gmail.com";
private final String foldername = "INBOX";
#Override
public void contextInitialized(ServletContextEvent sce) {
final ServletContext servletContext = sce.getServletContext();
executorService = Executors.newFixedThreadPool(3);
Session session = Session.getInstance(new Properties());
try {
final IMAPStore store = (IMAPStore) session.getStore("imaps");
store.connect(mailhost, username, password);
final Folder folder = store.getFolder(foldername);
if (folder == null) {
servletContext.log("Folder in mailbox bestaat niet.");
return;
}
folder.open(Folder.READ_ONLY);
MessageCountListener countListener = new AnalyzerService();
folder.addMessageCountListener(countListener);
Runnable runnable = new Runnable() {
#Override
public void run() {
while (true) {
try {
servletContext.log("Aantal berichten in folder: " + folder.getMessageCount());
servletContext.log("Idling");
store.idle();
} catch (MessagingException ex) {
servletContext.log(ex.getMessage());
return;
}
}
}
};
executorService.execute(runnable);
servletContext.log("Executorservice gestart");
} catch (MessagingException ex) {
servletContext.log(ex.getMessage());
}
}
#Override
public void contextDestroyed(ServletContextEvent sce) {
sce.getServletContext().log("Context wordt vernietigd");
executorService.shutdown();
sce.getServletContext().log("Executorservice gestopt");
}
}
The AnalyzerService.java:
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.event.MessageCountEvent;
import javax.mail.event.MessageCountListener;
class AnalyzerService implements MessageCountListener {
public AnalyzerService() {
}
#Override
public void messagesAdded(MessageCountEvent event) {
Message[] addedMessages = event.getMessages();
for (Message message : addedMessages) {
try {
System.out.println(message.getSubject());
} catch (MessagingException ex) {
System.out.println(ex.getMessage());
}
}
}
#Override
public void messagesRemoved(MessageCountEvent event) {
Message[] removedMessages = event.getMessages();
for (Message message : removedMessages) {
try {
System.out.println(message.getSubject());
} catch (MessagingException ex) {
System.out.println(ex.getMessage());
}
}
}
}
while (true) {
try {
servletContext.log("Aantal berichten in folder: " + folder.getMessageCount());
servletContext.log("Idling");
store.idle();
} catch (MessagingException ex) {
servletContext.log(ex.getMessage());
return;
}
}
has exactly 2 3 possibilities to end earlier than never run only once.
The loop actually ends either:
Through the explicit return in case of a MessagingException. Look at your logs, there either a message or something strange like "null". Consider using a proper stacktrace log (.log(String message, Throwable throwable)) since Exception#getMessage() is often empty or not telling you much.
Through any unchecked exception. You should notice that in some log though since uncaught exceptions via executorService.execute should invoke the nearest uncaught exeption handler which is generally bad. See Choose between ExecutorService's submit and ExecutorService's execute
The loop stops executing after it logs "Idling"
store.idle() never returns. (every other line of code could do that theoretically as well, e.g. the folder.getMessageCount() call in a 2nd iteration but that's very unlikely)
Regarding No 3 - the documentation
Use the IMAP IDLE command (see RFC 2177), if supported by the server, to enter idle mode so that the server can send unsolicited notifications without the need for the client to constantly poll the server. Use a ConnectionListener to be notified of events. When another thread (e.g., the listener thread) needs to issue an IMAP comand for this Store, the idle mode will be terminated and this method will return. Typically the caller will invoke this method in a loop.
If the mail.imap.enableimapevents property is set, notifications received while the IDLE command is active will be delivered to ConnectionListeners as events with a type of IMAPStore.RESPONSE. The event's message will be the raw IMAP response string. Note that most IMAP servers will not deliver any events when using the IDLE command on a connection with no mailbox selected (i.e., this method). In most cases you'll want to use the idle method on IMAPFolder.
That sounds like this method is not designed to return any time soon. In your case never since you don't issue any commands towards the server after you enter idle. Besides that
folder.idle() could be what you should actually do
I guess the documentation is wrong, however ConnectionListener and MessageCountListener are two different things.
