Simple Java Tips | Selenium Uses

1| Handling Exception | Assertion

Multiple Catch Blocks
Multiple catch avoid quit tests from various Exception

try
{
   assertEquals(actual, expected);
}catch(Exception e)
{
   System.out.println("...");
}catch(NullPointerException e)
{
   System.out.println("...");
}catch(IOException e)
{
   System.out.println("...");
}catch(ComparisonFailure e)
{
   System.out.println("...");
}


Finally Keyword
The finally keyword always executes

try
{
   assertEquals(actual, expected);
}catch(Exception e)
{
   System.out.println("...");
}finally
{
   System.out.println("...");
}


2| Java Arrays

Store values as a list of arrays for assertion.

#1
List<WebElement> savedItem = driver.findElement(By.id(Value)).findElements(By.tagName("li"));
ArrayList<String> storelist = new ArrayList<String>();
for(int i=0; i<savedItem.size(); i++) 
{
String d = savedItem.get(i).findElement(By.id(Value)).getText();
storelist.add(d);
System.out.println(storelist.get(i));
}

#2
String content[]={"string1","string2","string3","string4","string5"};
for(int i=0; i<content.length; i++){
if(isElementPresent(By.cssSelector("ul#"+content[i]+" > li")))
{
// Perform your code
}


3| Date Format

Date Format can be asserted using Java DateFormat.

String element = driver.findElement(By.xpath(Value)).getText();    
String Result = element.substring(6);
System.out.println(Result);   
    
DateFormat format = new SimpleDateFormat("MMM dd, yyyy");  // Date Format can be modified link
Date dif = format.parse(Result);
System.out.println(dif);

4| Random Select

Elements can be selected randomly using Random().

List<WebElement> element = driver.findElement(By.id(Value)).findElements(By.tagName("li"));
    
Random r=new Random();
int index = r.nextInt((element.size()-1)-0+1)+0;  // int index = r.nextInt(max - min + 1) + min;    
String id = element.get(index).getAttribute(Value);
System.out.println(id);


5| Sort Arraylist

Elements can be sorted either in ascending order or descending order.

List<WebElement> savedItem = driver.findElement(By.id(Value)).findElements(By.tagName("li"));
ArrayList<String> storelist = new ArrayList<String>();
for(int i=0; i<savedItem.size(); i++) 
{
String d = savedItem.get(i).findElement(By.tagName("a")).getText();
storelist.add(d);
System.out.println(storelist.get(i));
}

Collections.sort(storelist); // Ascending order
System.out.println(storelist);
Collections.reverse(storelist); // Descending order

  3. Automation testing mainly focus on Java training in chennai and needs java knowledge.So we need to get Java training in chennai to be expert in selenium. All the training were listed in software testing training in chennai
