Avoid explicit delay in selenium

If you are using java with selenium for automation,then you should use explicit delay in your code(like Thread.sleep(2000)).

Here is an example for same:

WebDriverWait wait = new WebDriverWait(webDriver, 5);//here 5 is a maximum waiting time in seconds
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@value='SignIn']")));

//ExpectedConditions have lot of functions for different actions,so use these functions according your requirement.

Mouse over on "element" using selenium

Here is is example of mouse over

Actions builder=new Actions(driver);
builder.moveToElement(tagElement).build().perform()

How to move cursor in selenium.

In automation testing,you need cursor movement for displaying hidden elements.

Here is a example:

public void mouseOverOnElement(WebElement tagElement)
{
try
{
Actions builder=new Actions(driver);
Point coordinate=tagElement.getLocation();
Robot robot=new Robot();
builder.moveToElement(tagElement, 5,5).build().perform();
builder.moveByOffset(1, 1).build().perform();
robot.mouseMove(coordinate.getX()+8,coordinate.getY()+60);

}
catch(Exception e)
{
logger.info("Error message in mouseOverOnElement method-->"+e);
}
}

Using the above code you are able to move mouse cursor.

How to rerun failed testcases using testng.

If you want automatically rerun your failed testcases after completion,then use below approach:
Note:i think you know that whenever testcase is failed in testng,it creates a "testng-failed.xml" for failed testcases.

1)if you want to rerun automatically only failed testcases then you need modify pom.xml.
2) Run time you need to change testng.xml file path to "testng-failed.xml" in pom.xml.This you can do using any script language.I have done same using batch script.
Below is the batch script for same:

setlocal enabledelayedexpansion
set INTEXTFILE=pom.xml
set OUTTEXTFILE=pom_out.txt
set SEARCHTEXT=src/main/resources/testng.xml
set REPLACETEXT=target/failsafe-reports/testng-failed.xml
set OUTPUTLINE=

call mvn integration-test


for /f "tokens=1,* delims=¶" %%A in ( '"type %INTEXTFILE%"') do (
SET string=%%A
SET modified=!string:%SEARCHTEXT%=%REPLACETEXT%!

echo !modified! >> %OUTTEXTFILE%
)
del %INTEXTFILE%
rename %OUTTEXTFILE% %INTEXTFILE%

call mvn integration-test

for /f "tokens=1,* delims=¶" %%A in ( '"type %INTEXTFILE%"') do (
SET string=%%A
SET modified=!string:%REPLACETEXT%=%SEARCHTEXT%!

echo !modified! >> %OUTTEXTFILE%
)
del %INTEXTFILE%
rename %OUTTEXTFILE% %INTEXTFILE%

3) Now start execution using above batch file.

How to immediate rerun failed testcase using testng.

After developing a automation framework,now a automation tester want to reduce a false positive rate,so he/she will use immediate rerun of failed test case for reducing the failed test due to setup and network problem.

Below is the code for same:

1) Create a class with your rerun logic

Using the below logic you can immediate rerun your failed test case.
package com.companyName.web.utils;

import org.testng.IRetryAnalyzer;
import org.testng.ITestResult;

public class Retry implements IRetryAnalyzer{
private int retryCount = 0;
private int maxRetryCount = 3;
public boolean retry(ITestResult result) {

if(retryCount < maxRetryCount) { retryCount++; return true; } return false; } }

2) use below annotation in your test program
@Test(groups="groupName",retryAnalyzer=Retry.class)
if you are not using group then use this
@Test(retryAnalyzer=Retry.class)
