Running TestNG Programmatically or How to execute TestNG xml from Runnable JAR file

I have researched lot, how to execute the TestNG xml from a Java class because I wanted to make my whole project in to a Runnable JAR file and execute it anywhere outside eclipse. This was already in the TestNG docs, but I couldn't understand this first time.

Advantages of this method:

• You can execute your tests outside eclipse, any machine provided JRE is installed on the machine. You don't need to place the libraries too, The JAR will have all these.
• Without a Selenium grid, this enables you to  run the tests on any previous versions of browsers running on another machine.
• This can be executed by anyone without any knowledge of Eclipse, scripting etc.

How to do this:

Assuming you are running your test cases by executing testNG.xml as TestNG.

Steps:

Create a Java class with main method with below code.

public class MainTest {
    public static void main(String[] args){
    List<String> file = new ArrayList<String>();
    file.add("D:/Selenium_workspace/Framework/src/Framework.xml");
    TestNG testNG = new TestNG();
    testNG.setTestSuites(file);
    testNG.run();}
}

Now Export your whole project to runnable JAR. Double click the JAR, will execute the xml as testNG. You may create a user interface to select XML so that it adds flexibility to select which test you need to run.

Automation of date widget having month/year navigation only through Prev', 'Next' buttons

In this post I will give you a code how to automate selection of date from a date widget neither has the date input and also direct navigation to the months/years. This widget only has the 'Prev', 'Next' buttons to navigate to next months/previous months.

Please find the code below:

public class DateWidgetSample {

public static void main(String args[]){

 String date1="12/04/2016";

 String date2="12/12/2015";

 SimpleDateFormat fmt= new SimpleDateFormat("dd/MM/yyyy");

 Date datevar1 = null;

 Date datevar2 = null;

 try {

  datevar1 = fmt.parse(date1);

  datevar2 = fmt.parse(date2);

 } catch (ParseException e) {

  // TODO Auto-generated catch block

  e.printStackTrace();

 }

 Calendar cal1 = Calendar.getInstance();

 Calendar cal2 = Calendar.getInstance();

 cal1.setTime(datevar1);

 cal2.setTime(datevar2);

 cal1.set(Calendar.DAY_OF_MONTH, 1);

 cal2.set(Calendar.DAY_OF_MONTH, 1);

 int diffYear = cal2.get(Calendar.YEAR) - cal1.get(Calendar.YEAR);

 int diffMonth = diffYear * 12 + cal2.get(Calendar.MONTH) - cal1.get(Calendar.MONTH);

 System.out.println(diffMonth);

}

}

Result output is difference of months.

Next you have to do is have a for loop to click the previous/next button based on the number of months obtained in the output. If the number is a positive value, ask to click the next button. If it's a negative value, click the Previous button. That's all. Check code below.

if(diffMonth>0){

for(int i=0; i<diffMonth; i++){

driver.findElement(By.id("nextbtn").click();

}

}

if(diffMonth<0){

for(int j=0; j<diffMonth; j++){

driver.findElement(By.id("previousbtn").click();

}

}
