TestNG Introduction

 TestNG  :

What is TestNG? 

TestNG is a testing framework inspired by JUnit and NUnit but designed to cover a wider range of test categories, from unit tests to integration tests. 

Why should we go for TestNG?

TestNG offers several advantages that make it a preferred choice for testing: 

You can run a single class or multiple classes.

Example: Running as a Java application

A.Java

B.Java

C.Java 

You can group test cases for different types of testing such as smoke tests, regression tests, and integration tests.

  ex:   smoke test cases

        regression test cases

      Integration test cases

 

You can run test cases based on priority

       test(priority =0)  --> 1st

       test(priority =1)  --> 2nd

 

You can run test cases in parallel--> parallel testing

             tc1

            tc2

            tc3

 

            Can run all  test cases at the same time

            tc1  6pm

            tc2  6pm

            tc3  6pm

 

TestNG allows you to generate reports and log user-defined messages.

            Java -   Syso.println("");

      Selenim -  will not generate any automation results - so we go for TestNG

 

We can perform DDT

            Data Driven Testing :  testing the application with multiple/different sets of data

 

Example 1: Login functionality with different users and passwords.        

            user     pwd

            -----------------

            ram,     mercury         

            Sita,     mercury

            Raju,   mercury

 

Example 2: Creating orders with different product names, quantities, and addresses.

                                    Productname Qty   Address

                                    ------------------------------

                                    Samsung,        2,         BNG

                                    Shampoo,        3,         CHN

                                    Santoor,          5,         HYD

Download Files in Chrome, Firefox, etc.

Setting Download Location in Chrome:

To set a default download location in Chrome, follow these steps:

1. Manual Settings:
• Open Chrome.
• Click the three dots (menu) in the top-right corner.
• Select Settings.
• In the search bar, type downloads.
• Scroll to the bottom to see Downloads settings.
• Under Location, you will see the default download path (e.g., C:\Users\Lenovo\Downloads).
• You can change the download location by clicking Change.
• To prompt where to save each file before downloading, enable Ask where to save each file before downloading.

 

Note:

We can change downloads location folder name .

 

 

2.     Automated Settings with Selenium:

• To change download settings in automation, you need to configure ChromeOptions and FirefoxOptions.

 

 

DownLoad File in default Location:

 

package UploadfileBasics;

 

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.chrome.ChromeDriver;

 

public class DownloadsFileInDefaultLocation {

 

            public static void main(String[] args) {

                        System.setProperty("webdriver.chrome.driver", ".\\Drivers\\chromedriver.exe");

 

                        //                     //open chrome browser

                        WebDriver  driver =  new ChromeDriver();               

                        driver.get("https://www.w3schools.com/howto/tryit.asp?filename=tryhow_html_download_link2");

 

                        // click Logo

//                     driver.findElement(By.xpath("//img[@alt='W3Schools']")).click();

                                               

 

                        //selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//img[@alt='W3Schools']"}

 

                        // first Check that ele is in frame, if it is in frame, we have to  swicth control to frame..

                        //   by name or id  or indexno or Webele

                        // Switch to Frame

                        driver.switchTo().frame("iframeResult");

                       

                                    // click Logo

                                    driver.findElement(By.xpath("//img[@alt='W3Schools']")).click();

 

                        //   it downloads file in default location of chrome browser ????

 

                        // Switch control to main page

                        driver.switchTo().defaultContent();

                        System.out.println("ends");

 

            }

 

}

 

 

DownLoad File in Specific folder /Project Location:

 

// set  download location for Automation

                        HashMap<String, Object> hm = new HashMap<String, Object>();

 

                        // dont want popup window Where we need to save the file -- disable popup window - asking where to save the

                        hm.put("profile.default_content_settings.popups", 0);

 

                        // To download any file in the given location

                        hm.put("download.default_directory", "C:\\brahma\\MyDownloads");

//                     C:\brahma\MyDownloads

SSL Error (or) Security Certificates Handling

 

FAQ: SSL Error (or) Security Certificates Handling

There are times when we open a webpage and it displays a warning saying that "This web page is not trusted/Secured." It may ask, "Do you want to continue?" This happens when the website is not secured or trusted, leading to a security certificate error.

When :

 

if website is not secured  / trusted,  it displays  Security ceritificate error

 

 

Click continue to open the web site

 

with out handling Certificate error:

 

           

package SecurityDownloadsBasics;

 

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.chrome.ChromeDriver;

 

public class HandlingCertificateErrors {

 

            public static void main(String[] args) {

                        // TODO Auto-generated method stub

                        System.setProperty("webdriver.chrome.driver", ".\\Drivers\\chromedriver.exe");

                        //

                        //                     //                     //open chrome browser

                                                WebDriver  driver =  new ChromeDriver();    // Def constr           

                                                driver.get("https://expired.badssl.com/");

 

                        // Your connection is not private

                        //                     Attackers might be trying to steal your information from expired.badssl.com (for example, passwords, messages, or credit cards). Learn more

                        //                     NET::ERR_CERT_DATE_INVALID

 

                        // HW click advanced >  ClicK Proceed button

 

            }

 

}

 

                       

Handling Certificate error using "ChromeOptions":

 

// ChromeOptions-is predefined class in Selenium 

                                    //can be used to apply Different  settings/ to apply Different  options to chrome browser

                                    // // to accept Security certificate

 

 

------------------------------           

 

package UploadfileBasics;

 

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.chrome.ChromeDriver;

import org.openqa.selenium.chrome.ChromeOptions;

 

import com.sun.tools.classfile.StackMapTable_attribute.chop_frame;

 

public class HandlingCertificateErrorsUsingChromeOptions {

 

            public static void main(String[] args) {

                        System.setProperty("webdriver.chrome.driver", ".\\Drivers\\chromedriver.exe");

                        // Handle security certificate error  --> use ChromeOptions -class

                        // create obj for ChromeOptions-class

                        ChromeOptions chOptions = new ChromeOptions();

                        // accepts security certificate error -->  some method

                        chOptions.setAcceptInsecureCerts(true);

                        //   pass   true value

                       

                        //  inform browser with above settings/pass chromeoptions ref var in chromedriver

                        //                                             //                     //open chrome browser

//                     WebDriver driver=  new ChromeDriver();//  no  parameter (or) DC

                        WebDriver driver = new ChromeDriver(chOptions);

                       

                        // 1 PC

                        // while opening chrome browser - it opens with given options/ settings

 

                        driver.get("https://expired.badssl.com/");//  //  no certificate error

                       

                        // check certificate error -->  wont display SSL error now

                                   

 

                        System.out.println("ends here");

 

 

            }

 

}
