URLs are in the file, need to copy from this file and hit in the browser. This process need to be done for all the URLs one by one. File size is less than 1 MB in max conditions. After downloading completes then only another file downloading will start, that means at any time active download is 1.
This process i am doing manually, for downloading of 125 files. This number may increase in coming days. So I am planing to automate this process. Can i achieve this in selenium?
I have knowledge on selenium webdriver, i can able to write the simple scripts.
If it is not possible with selenium, refer the any alternate ways.
Use the below code to rad from excel sheet
public class excel {
public static String getExcelData(String sheetName, int rowNum,int colNum)
{
String url=null;
try
{
FileInputStream fis=new FileInputStream("filepath.xls");
Workbook wb=WorkbookFactory.create(fis);
Sheet s=wb.getSheet(sheetName);
Row r=s.getRow(rowNum);
Cell c=r.getCell(colNum);
retval=c.getStringCellValue();
}
catch(Exception e)
{
e.printStackTrace();
}
return url;
}
}
Code will return you the url
use this url for downloading the file
WebDriver driver;
driver.get(url);
This will down load the file.
Firstly, read the excel file using Selenium/Java. Refer below link for more information:
https://www.guru99.com/all-about-excel-in-selenium-poi-jxl.html
Read url from excel sheet one after the other:
while(current_row<=row_count)
{
driver.get("url captured from the excel")
}
I assume that file gets downloaded automatically when you hit the url. In case of any specific element to be displayed after download is done, you can waitUntilElementVisible or Sikuli can be used for downloading ( In case of manual download)
I am showing image list in a html table. I have one column in the table as image name and made it as link so user can click and download the image. The image list come from database which are saved as byte array and while sending to client side I am converting it to static object as shown below
given below
FileContent = Utilities.GetString(item.FileContent);
//GetString method
public static object GetString(byte[] bytes)
{
try
{
MemoryStream stPictureSource = new MemoryStream(bytes);
var sr = new StreamReader(stPictureSource);
return sr.ReadToEnd();
}
catch(Exception ex)
{
Logger.Log(ex);
return string.Empty;
}
}
So,Can some one have an idea, how to download image in browser.

My scenario is, I'm getting same error page on many of my button clicks on the site.
I want to take screenshots, of this same error page, with reference on which link of the site this error page occured.
So I want screenshot whenever this error page occurs on any click.
Can you suggest me how to write the function for this and how to call that function in some other function in selenium Webdriver.
Please share some code sample for that.
As of currently, I'm writing it only as :
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(scrFile, new File("D:\\Home\\Ruchi\\failure.png"));
But in this I need to write these lines of code after every failure occurrence.
use try and catch block
try{
// Put your script here
}
catch(Exception ex)
{
File scrn=((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
// extracting date for folder name.
SimpleDateFormat sdfDate1 = new SimpleDateFormat("yyyy-MM-dd");//dd/MM/yyyy
Date now1 = new Date();
String strDate1 = sdfDate1.format(now1);
// extracting date and time for snapshot file
SimpleDateFormat sdfDate = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss");//dd/MM/yyyy
Date now = new Date();
String strDate = sdfDate.format(now);
String filefolder="./Snap/"+strDate1+"/"; // create a folder as snap in your project directory
// Creating folders and files
File f = new File(filefolder+strDate+".jpeg");
FileUtils.copyFile(scrn, new File(f.getPath()));
}
If your script fails then the program jumps to catch block and then code will take screen shot for you
Hope it will help you :)
I am using Selenium with Java to run scripts on android (thru Appium server).
I see that it is not possible to locate a toast by using selenium's
driver.findElement(By.LinkText("User not logged in")
in Appium
But can be used in Selendroid to capture toast messages.
I there a way I can use both Selendroid and Appium in the same script?
Finally, we are able to read the toast message without the need of taking screenshots and performing OCR.
I have tested this on Appium 1.15.1.
Toast messages comes under com.package.system.
Normally, Xpath for this will be "/hierarchy/android.widget.Toast".
And, Class Name will be "android.widget.settings"
You can confirm this by refreshing element inspector screen when toast message is displayed.
WebDriverWait waitForToast = new WebDriverWait(driver.25);
waitForToast.until(ExpectedConditions.presenceOfElementLoacted(By.xpath("/hierarchy/android.widget.Toast")));
String toastMessage = driver.findElement((By.xpath("/hierarchy/android.widget.Toast")).getText();
System.out.println(toastMessage);
Method 1: from Appium version 1.6.4 supports toast messages, for that you need to use automationName:'uiautomator2'.
toast = driver.find_element(:xpath, "//android.widget.Toast[1]")
if toast.text == "Hello"
But i don't recommend this because uiautomator2 is not stable yet.
Method 2:
Trigger text message on the screen
Capture screenshots
Convert image to text file
def assettoast(string)
sname = (0...8).map { (65 + rand(26)).chr }.join
$driver.driver.save_screenshot("#{sname}")
# Make sure tesseract is installed in the system. If not you can install using "brew install tesseract" in mac
system ("tesseract #{sname} #{sname}")
text_file="#{sname}.txt"
var= get_string_from_file(string, text_file)
raise if var != true
end
Check whether toast message is there in text file
def get_string_from_file(word, filename)
File.readlines(filename).each do |line|
return true if line.include?(word)
end
end
Looks like you can't switch driver type within same session.
If you trying to switch to Selendroid only for toast verification - you could use OSR image recognition engine.
Check this answer w/ Ruby bindings
Idea is quite simple:
make toast message to appear
take few screenshots
iterate over taken screenshots and look for required text
Here is nice and simple example of OCR usage in Java: tess4j example (make sure that Tesseract engine installed)
Step 1:
File scrFile=null;
String path1 = null;
BufferedImage originalImage=null;
BufferedImage resizedImage=null;
System.out.println("Starting\n\n\n\n");
scrFile = ((TakesScreenshot) appiumDriver).getScreenshotAs(OutputType.FILE);
System.out.println("after scrfile\n\n\n\n");
originalImage = ImageIO.read(scrFile);
System.out.println("after originalFile\n\n\n");
BufferedImage.TYPE_INT_ARGB : originalImage.getType();
resizedImage = CommonUtilities.resizeImage(originalImage, IMG_HEIGHT, IMG_WIDTH);
ImageIO.write(resizedImage, "jpg", new File(path + "/"+ testCaseId + "/img/" + index + ".jpg"));
Image jpeg = Image.getInstance(path + "/" + testCaseId + "/img/"+ index + ".jpg");
Step 2:
BufferedImage pathforToast= original image;
Step 3:
System.setProperty("jna.library.path","C:/Users/Dell/workspace/MOBILEFRAMEWORK/dlls/x64/");
Tesseract instance = Tesseract.getInstance();
`enter code here`ImageIO.scanForPlugins();
String result=null;
result = instance.doOCR(pathforToast);`enter code here`
System.out.println(result);`enter code here`
Appium 1.6.4#beta latest version supports toast messages
Take screen shot of Toast Message page and try to convert the image file in to Text and verify the text using the below code.
public void imageconversion(String filePath) throws IOException,
{
ITesseract instance = new Tesseract();
//file path is the image which you need to convert to text
File imageFile = new File(filePath);
BufferedImage img = null;
img = ImageIO.read(imageFile);
BufferedImage blackNWhite = new BufferedImage(img.getWidth(),img.getHeight(), BufferedImage.TYPE_BYTE_BINARY);
Graphics2D graphics = blackNWhite.createGraphics();
graphics.drawImage(img, 0, 0, null);
//path where your downloaded tessdata exists
instance.setDatapath("E://ocr//data");
//What language you required to convert,( e.g. English)
instance.setLanguage("eng");
String result = instance.doOCR(blackNWhite);
System.out.println(result);
}
Appium Directly does not give any API to read toast message we need to do it using tess4j jar. First we need to take screen shot and then we need to read the text from screen shot using tess4j API.
static String scrShotDir = "screenshots";
File scrFile;
static File scrShotDirPath = new java.io.File("./"+ scrShotDir+ "//");
String destFile;
static AndroidDriver driver = null;
public String readToastMessage() throws TesseractException {
String imgName = takeScreenShot();
String result = null;
File imageFile = new File(scrShotDirPath, imgName);
System.out.println("Image name is :" + imageFile.toString());
ITesseract instance = new Tesseract();
File tessDataFolder = LoadLibs.extractTessResources("tessdata"); // Extracts
// Tessdata
// folder
// from
// referenced
// tess4j
// jar
// for
// language
// support
instance.setDatapath(tessDataFolder.getAbsolutePath()); // sets tessData
// path
result = instance.doOCR(imageFile);
System.out.println(result);
return result;
}
/**
* Takes screenshot of active screen
*
* #return ImageFileName
*/
public String takeScreenShot() {
File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MMM-yyyy__hh_mm_ssaa");
new File(scrShotDir).mkdirs(); // Create folder under project with name
// "screenshots" if doesn't exist
destFile = dateFormat.format(new Date()) + ".png"; // Set file name
// using current
// date time.
try {
FileUtils.copyFile(scrFile, new File(scrShotDir + "/" + destFile)); // Copy
// paste
// file
// at
// destination
// folder
// location
} catch (IOException e) {
System.out.println("Image not transfered to screenshot folder");
e.printStackTrace();
}
return destFile;
}

I found three ways to capture a Toast message and verify them.
To get the page source and verify the toast message from it.
public void verifyToastMessageUsingPageSource(String toastmsg) throws InterruptedException {
boolean found = false;
for(int i =0 ; i <8; i++){
if(getDriver().getPageSource().contains("class=\"android.widget.Toast\" text=\""+toastmsg+"\"")){
found = true;
break;
}
Thread.sleep(300);
}
Assert.assertTrue(found,"toast message "+toastmsg+" is present");
}
Similar can be found using Xpath: //android.widget.Toast[1]
Using the grep command, wait for a toast message in uiautomator events.
run the command before clicking and toast message will be varified.
adb shell uiautomator events | grep "ToastMessgae"
This is tricky and needs more code to run.
start capturing screenshots thread.
perform click action
stop screen capturing thread.
extract text from the captured images using OCR and verify the toast message is present in the captured images.
I prefer the 1st and 2nd option, it provides validation in less time with less code.
comment if you need code for 2nd and 3rd point.
Appium with version number>=1.6.4 supports toast notification with UiAutomator2.
In Javascript with webdriver you can do like this
let toast=await driver1.elements("xpath","/hierarchy/android.widget.Toast");
let data=await toast[0].text();
console.log(data)
I am trying to do a file upload from Silverlight(Client Object Model) to Sharepoint 2010 library.. Please see the code below..
try{
context = new ClientContext("http://deepu-pc/");
web = context.Web;
context.Load(web);
OpenFileDialog oFileDialog = new OpenFileDialog();
oFileDialog.FilterIndex = 1;
oFileDialog.Multiselect = false;
if (oFileDialog.ShowDialog().Value == true)
{
var localFile = new FileCreationInformation();
localFile.Content = System.IO.File.ReadAllBytes(oFileDialog.File.FullName);
localFile.Url = System.IO.Path.GetFileName(oFileDialog.File.Name);
List docs = web.Lists.GetByTitle("Gallery");
context.Load(docs);
File file = docs.RootFolder.Files.Add(localFile);
context.Load(file);
context.ExecuteQueryAsync(OnSiteLoadSuccess, OnSiteLoadFailure);
}
}
catch (Exception exp)
{
MessageBox.Show(exp.ToString());
}
But I am getting the following error
System.Security.SecurityException: File operation not permitted. Access to path '' is denied.
at System.IO.FileSecurityState.EnsureState()
at System.IO.FileSystemInfo.get_FullName()
at ImageUploadSilverlight.MainPage.FileUpload_Click(Object sender, RoutedEventArgs e)
Any help would be appreciated
Thanks

Silverlight runs with very restricted access to the client user's filesystem. When using an open-file dialog, you can get the name of the selected file within its parent folder, the length of the file, and a stream from which to read the data in the file, but not much more than that. You can't read the full path of the file selected, and you are getting the exception because you are attempting to do precisely that.
If you want to read the entire content of the file into a byte array, you'll have to replace the line
localFile.Content = System.IO.File.ReadAllBytes(oFileDialog.File.FullName);
with something like
localFile.content = ReadFully(oFileDialog.File.OpenRead());
The ReadFully method reads the entire content of a stream into a byte array. It's not a standard Silverlight method; instead it
is taken from this answer. (I gave this method a quick test on Silverlight, and it appears to work.)
