Writing Selenium Test Cases

Writing Selenium Test Cases, Select Manual Test Cases, Selenium Test Environment Setup, and write & execute/run Selenium WebDriver Test cases.

To write these Selenium Test cases I used a sample application, You too can use this application for learning/practicing Selenium Test Cases.

Selenium WebDriver Test Cases

Prerequisites for writing Selenium WebDriver Test Cases…

1. Selected Manual Test Case for Automation
2. Element Locators to Locate/Recognize/Identify Elements/Objects
3. Selenium WebDriver API Commands to perform operations on elements
4. Programming Concepts to enhance the Test Cases
5. Testing Framework (Junit/TestNG) to group Test cases, prioritize Test cases, execute Test batches and generate Test Reports.

Note: Selenium WebDriver Test cases in this tutorial were written by using Eclipse IDE, Selenium WebDriver, and Java.

Generally, we use Testing Framework (Ex: TestNG) for inserting verification points and generating Test Reports, but in this practice tutorial, I used Java control flow statements to insert verification points and generating Test Results. So these Test cases are only for learning purposes, in Real-time we use Testing Framework as the Test Runner.

First focus on Selenium Test Environment Setup:

Choose Selenium Tool/s and other third-party plugins & frameworks for testing

Eclipse IDE, Java, Selenium WebDriver, TestNG, Maven, Jenkins, Extend Reports.

Steps:

1. Download & Install Java (JDK) Software – Write / Create & Run / Execute programs / test cases
(We use programming syntax to write test cases, we use programming features called variables, operators, control flow, methods, exception handling, etc, to enhance test cases)

2. Set Java environment variable path (path variable) – to use Java software from any directory in your machine/computer.

3. Download Eclipse IDE & Extract – to write Java programs, syntax guidance, context help, auto compilation, and integrate several plug-ins & frameworks with Selenium.

4. Download Selenium WebDriver Java language binding (from www.selenium.dev) and add WebDriver jar file/s to Java project in Eclipse IDE.

5. Download Browser driver/s and set browser path in test cases (instantiate browser driver)

System.out.println(“User Registration is Successful – Passed”);
}
else {
System.out.println(“User Registration is Unsuccessful – Failed”);
}
driver.close();

Test Case 8: Data-Driven Testing for “Admin Login” functionality by reading test data from a text file.

What is Data-Driven Testing?
Data-driven testing is the creation of test scripts where test data and/or output values are read from data files instead of using the hard-coded values each time the test runs.

Why Data-Driven Testing?
For conducting Positive and Negative Testing

Difference between Parameterization and Data-Driven Testing?
For passing a single value or multiple values we use Parameterization, we use multiple values only for Data-driven testing.

How to conduct Data-Driven Testing?
By using any resource (Test Data file) we can conduct Data-driven testing.

Steps for Data-Driven Testing:
1. Read Test Data from an external file
2. Create a Test case
3. Connect Test data with the Test case

Selenium Data-Driven Test Case

System.setProperty(“webdriver.chrome.driver”, “C:\\Users\\user\\Downloads\\chromedriver.exe”);

FileReader fileObject = new FileReader(“C:\\Users\\user\\Desktop\\input.txt”);
BufferedReader br = new BufferedReader(fileObject);
String line;
int lineCount=0;
int Iteration=0;

while ((line = br.readLine()) !=null) {
String inputData [] = line.split(“, “, 2);
lineCount=lineCount+1;

if (lineCount>1) {
Iteration=Iteration+1;

WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get(“https://gcreddy.com/project/admin/login.php”);
driver.findElement(By.name(“username”)).sendKeys(inputData[0]);
driver.findElement(By.name(“password”)).sendKeys(inputData[1]);
driver.findElement(By.id(“tdb1”)).click();
Thread.sleep(2000);

String url= driver.getCurrentUrl();

if (url.equals(“https://gcreddy.com/project/admin/index.php”)) {
System.out.println(Iteration + ” Admin Login is Successful – Passed”);
}
else {
System.out.println(Iteration+” Admin Login is Unsuccessful – Failed”);
}
driver.close();
}
}
br.close();
fileObject.close();
}
}

Test Case 9: Write a Test case for Admin Login Locking Functionality in gcrShop application admin interface.

Business Rule: Admin Login will be locked for 5 minutes after 3 failed login attempts.

Test Steps:
1. Launch the Browser
2. Navigate to (Load) gcrShop admin interface login page /home page (https://gcreddy.com/project/admin/login.php)
3. Enter “Username”
4. Enter “Password”
5. Click the “Login” Button

Verification Point
Capture the Error message and compare it with expected for 4 times

Expected:
1st iteration: Error: Invalid administrator login attempt.
2nd iteration: Error: Invalid administrator login attempt.
3rd iteration: Error: Invalid administrator login attempt.
4th iteration: Error: The maximum number of login attempts has been reached. Please try again in 5 minutes.

Test Data:
Ref: input.txt

Locating Elements:
Username – edit box – name – username
Password – edit box – name – password
Login – Button – id – tdb1
Error Message – Text Area – className – messageStackError

Selenium WebDriver Test Script:

public class TestCase {
static WebDriver driver;
static String ErrorMessage;

public static void main(String[] args) throws IOException, InterruptedException {
System.setProperty(“webdriver.chrome.driver”, “E://chromedriver.exe”);

FileReader file = new FileReader (“C:\\Users\\mahit\\Desktop\\input.txt”);
BufferedReader br = new BufferedReader(file);

int count=0;
int iteration=0;
String line;

while ((line=br.readLine()) !=null) {
count = count+1;

if (count>1) {
iteration = iteration+1;

String inputData[] = line.split(“, “, 2);

driver = new ChromeDriver();

driver.manage().window().maximize();

driver.get(“https://gcreddy.com/project/admin/login.php”);
driver.findElement(By.name(“username”)).sendKeys(inputData[0]);
driver.findElement(By.name(“password”)).sendKeys(inputData[1]);
driver.findElement(By.id(“tdb1”)).click();
Thread.sleep(2000);

ErrorMessage = driver.findElement(By.className(“messageStackError”)).getText();

if ((iteration == 4) && (ErrorMessage.contains(“The maximum number of login attempts has been reached. Please try again in 5 minutes.”))) {
System.out.println(iteration+ ” Maximum invalid login attempts are over – Passed”);
}
else if ((iteration <= 3) && (ErrorMessage.contains(“Error: Invalid administrator login attempt.”))) {
System.out.println(iteration+ ” Maximum invalid login attempts are Not over – Passed”);
}
else
{
System.out.println(iteration+” Failed”);
}
driver.close();
}
}
br.close();
file.close();
}
}

}
else{
System.out.println(“Test Case 1: “+ “Admin Login is unsuccessful – Failed”);
}
obj.closeBrowser();
//Verify Error Message in Admin Login Functionality (Negative Test Case)
obj.launch();
obj.login(“admin1”, “abcder”);

String ErrorMessage=driver.findElement(By.className(“messageStackError”)).getText();
//System.out.println(ErrorMessage);
if (ErrorMessage.contains(“Error: Invalid administrator login attempt.”)){
System.out.println(“Test Case 2: “+ “Admin Login is Unsuccessful & Showing Correct Error Message -Passed”);
}
else {
System.out.println(“Test Case 2: “+ “Admin Login is Unsuccessful & Not Showing Correct Error Message -Failed”);
}
obj.closeBrowser();
//Test Case 3: Verify Redirect Functionality from Admin Interface to user Interface
obj.launch();
obj.login(“admin”, “admin@123”);
driver.findElement(By.linkText(“Online Catalog”)).click();

System.out.println(“Test Case 3: “+ “Redirected from Admin Interface to User Interface – Passed”);
}
else {
System.out.println(“Test Case 3: “+ “Not Redirected from Admin Interface to User Interface – Passed”);
}
obj.closeBrowser();
}
}
