Automation Frameworks

Frameworks in Test Automation:

Utilizing a framework facilitates the structured organization of code, providing clear guidelines and best practices to methodically achieve desired outcomes.

Types of Automation Frameworks:

1. Linear Automation Framework
2. Modular Driven Framework
3. Data-Driven Framework
4. Keyword-Driven Framework
5. Hybrid Testing Framework
6. Behavior-Driven Development (BDD) Framework

Let's discuss each of these in detail.

1. Linear Automation Framework

    The Linear Automation Framework, often referred to as the Record & Playback approach, is characterized by its simplicity and ease of implementation. Unlike more complex frameworks, such as Data-Driven or Keyword-Driven frameworks, this approach involves the creation of test scripts within a single class or script file.

How Does It Work?

    Testers record their interactions with the application under test using specialized tools. These interactions are then converted into script commands stored in a single script file. During playback, the recorded actions are executed sequentially, mimicking user interactions.

Advantages:

• Quick Script Generation – Testers can create scripts quickly by recording their actions without extensive scripting knowledge.
• Low Barrier to Entry – Beginners can start automating tests with minimal training.
• Tool Familiarization – Helps testers become familiar with automation tools.

Disadvantages:

• Limited Reusability – Scripts are linear and cannot be easily reused across multiple tests.
• Hardcoded Test Data – Test data is embedded within scripts, making updates challenging.
• Maintenance Challenges – As the test suite grows, maintaining scripts becomes cumbersome.

---

---

2. Modular Driven Framework

    The Modular Driven Framework breaks down the application into smaller, independent parts (modules). Each module is tested separately using dedicated scripts, improving reusability and organization.

Advantages:

• Enhanced Reusability – Test scripts can be reused across different scenarios.
• Targeted Maintenance – Changes in an application require only specific modules to be updated.
• Cost-Efficient Maintenance – Clearly separated modules simplify updates and maintenance.

Challenges:

• Requires Technical Expertise – Knowledge of programming and testing concepts is needed.
• Time-Consuming Setup – Compared to linear automation, this approach requires careful planning.
• Hardcoded Test Data – Like the Linear Framework, test data may be embedded in scripts.

---

3. Data-Driven Testing Framework

    This framework builds upon the Modular Driven Framework by allowing test data to be dynamically supplied from external sources, such as:

• Excel files
• CSV files
• Databases
• Text files

    Instead of embedding data within scripts, test scripts retrieve data from these external files during execution.

When to Use:

    When testing the same functionality multiple times with different sets of input data.

Advantages:

• Separation of Test Data and Test Scripts – Updating test data does not affect scripts.
• Improved Test Coverage – A single test script can be reused with multiple datasets.
• Flexibility & Maintainability – Test data can be updated independently.

Disadvantages:

• Increased Complexity – Setting up test data sources requires extra effort.
• Requires Programming Skills – Testers must understand scripting and data handling.
• Time-Consuming Setup – Requires significant planning and preparation.

---

---

4. Keyword-Driven Testing Framework

    This framework uses keywords stored in an external data file to drive test execution. These keywords represent specific actions to be performed, making the framework structured and reusable.

Advantages:

• No Programming Skills Required – Testers can create tests using predefined keywords.
• Simplified Script Creation – Once set up, writing new tests is easier.
• High Code Reusability – Keywords can be used across multiple scripts.
• Tool Independence – Works with various test automation tools.
• Application Independence – Test cases can be designed even before development is complete.

Disadvantages:

• High Initial Setup Effort – Requires significant time and automation expertise.
• Higher Initial Investment – More suited for large applications.
• Complex Maintenance – Managing keywords can become challenging as the framework grows.
• Longer Learning Curve – Testers must learn how to use and manage keywords effectively.

---

5. Hybrid Testing Framework

    Hybrid Testing Framework combines features of multiple frameworks, such as Keyword-Driven and Data-Driven approaches, to enhance flexibility and scalability.

Key Components:

• Driver Script – Controls test execution flow.
• Configuration File – Stores settings and environment variables.
• Run Manager – Determines which tests to run.
• Test Cases & Scripts – Defines automation scenarios.
• Object Repository – Stores UI elements for easy identification.
• Test Data – Externalized data sources (Excel, CSV, Databases).
• Results & Logs – Stores test execution reports.
• Function Library – Collection of reusable functions.
• Scheduler – Automates test execution at predefined intervals.

Advantages:

• Best of Multiple Frameworks – Combines strengths of Keyword-Driven and Data-Driven frameworks.
• High Flexibility & Reusability – Adaptable to different testing needs.
• Faster Execution – Optimized test execution time.
• Scalability – Supports multi-platform and cross-browser testing.

Disadvantages:

• Requires Strong Technical Expertise – Developers must understand multiple frameworks.
• Higher Initial Effort – Requires significant setup time and investment.

---

6. Behavior-Driven Development (BDD) Framework

    BDD enables teams to create test cases in plain, human-readable language (e.g., English). This improves collaboration between testers, developers, and business analysts.

Given-When-Then Approach:

BDD follows a structured format:

• Given – Defines initial conditions.
• When – Describes user actions.
• Then – Specifies expected outcomes.

Example Feature File (Cucumber - Gherkin Format): gherkin

Feature: BDD implementation using Cucumber  

Scenario: Login to Gmail using Cucumber plugin  

  Given User is navigating to the Gmail login page  

  When User enters username as "Username" and password as "Password"  

  Then User is successfully navigated to the Gmail mailbox

Advantages:

• Improved Test Coverage – Ensures all user stories are tested.
• Readable Scenarios – Uses natural language for easy understanding.
• Test Automation Friendly – Works with Cucumber, SpecFlow, and JBehave.
• Code Reusability – Steps can be reused across test cases.
• CI/CD Integration – Easily fits into Continuous Integration pipelines.

Disadvantages:

• Requires Collaboration – Close coordination between developers and testers is needed.
• Risk of Misuse – If not used correctly, BDD can turn into an inefficient testing approach.

Conclusion:

Selecting the right automation framework depends on project requirements, team expertise, and long-term maintainability. Linear and Modular frameworks are best for small projects, while Data-Driven, Keyword-Driven, Hybrid, and BDD frameworks are ideal for large-scale automation efforts.

File Upload Using Selenium WebDriver

Exploring Different Approaches for File Upload with Selenium WebDriver:

........Incomplete.......

    File uploads are a common functionality on web applications, and automating this process is crucial for efficient testing with Selenium WebDriver. In this blog post, we will explore three different methods to upload files using Selenium WebDriver: 'SendKeys', the 'Robot' class, and 'AutoIT'.

Using SendKeys:

    The most straightforward approach for uploading a file in Selenium WebDriver is to use the 'SendKeys' method. This method is applicable only if the HTML input element has the attribute type="file". This attribute is specific to file upload functionality, and using Selenium's sendKeys method allows for the automatic selection of the desired file for this type of input field.

Syntax:

1. WebElement fileInput = driver.findElement(By.id("idvlaue"));
2. fileInput.sendKeys("path/to/your/file.txt");

Pros:

• Directly interacts with the file input element.
• Simple and concise code for file uploads.
• No external dependencies are required.

Cons:

• Limited to scenarios where the file input element is present.

Using Robot Class:

    The Robot class in Java can be used to simulate keyboard and mouse actions. In the context of the uploads, the Robot class can be used to navigate the file selection dialogue.

Example Program:

1. import java.awt.AWTException;
2. import java.awt.Robot;
3. import java.awt.Toolkit;
4. import java.awt.datatransfer.StringSelection;
5. import java.awt.event.KeyEvent;
6.  
7. import org.openqa.selenium.By;
8. import org.openqa.selenium.WebDriver;
9. import org.openqa.selenium.WebElement;
10. import org.openqa.selenium.chrome.ChromeDriver;
11. import org.openqa.selenium.chrome.ChromeOptions;
12.  
13. public class Dummy2 {
14. public static void main(String[] args) throws AWTException {
15. ChromeOptions co = new ChromeOptions();
16. co.addArguments("-remote-allow-origins");
17.  
18. WebDriver driver = new ChromeDriver();
19.                 driver.get("https://testingcolleges.blogspot.com/2024/01/file-upload-demo-page.html");
20.  
21. WebElement fileUploadBtn = driver.findElement(By.className("file-label-2"));
22. fileUploadBtn.click();
23.  
24. Robot rbt = new Robot();
25. rbt.delay(2000); // just like thread.sleep
26.  
27. //these below 2 lines used to copy the path 
28. StringSelection ss = new StringSelection("C:\\Users\\Dollar\\Desktop\\Dummy.txt");
29. // copy the above path in clipboard
30. Toolkit.getDefaultToolkit().getSystemClipboard().setContents(ss, null);
31. //Toolkit.getDefaultToolkit().getSystemClipboard().setContents("path", null);
32.  
33. //perform Ctrl+V operation to pass the copied path
34. rbt.keyPress(KeyEvent.VK_CONTROL);
35. rbt.keyPress(KeyEvent.VK_V);
36. rbt.keyRelease(KeyEvent.VK_CONTROL);
37. rbt.keyRelease(KeyEvent.VK_V);
38.  
39. //Enter press
40. rbt.keyPress(KeyEvent.VK_ENTER);
41. rbt.keyRelease(KeyEvent.VK_ENTER);
42.  
43. }
44. }

Pros:

• Works across different browsers.
• Can handle scenarios with hidden file input fields.

Cons:

• Requires handling keyboard events, which may be error-prone.
• Platform-dependent and may need adjustments for different operating systems.

Using AutoIT:

    AutoIT is a scripting language designed for automating the Windows GUI and general scripting tasks. It can be integrated with Selenium WebDriver to handle file Uploads.

Pros:

• Powerful for handling complex file upload scenarios.
• Works seamlessly across different browsers and operating systems.

Cons:

• Requires installing AutoIT and writing an external script.
• Add an external dependency to your automation project.

Conclusion:

    Each method for file upload with Selenium WebDriver has its advantages and limitations. The choice of method depends on the specific requirements of your application and the level of control and compatibility needed. While SendKeys is suitable for simple scenarios, the Robot class and AutoIT offer more flexibility and control, making them valuable tools for handling complex file upload functionalities.
