How to Manage Test Execution Across Different Browsers and Environments (QA, UAT, Staging)

By
In real-time automation projects, test execution is never limited to a single browser or a single environment . Applications must be validated across multiple browsers (Chrome, Firefox, Edge) and multiple environments such as QA, UAT, and Staging before going live.

Understanding Different Types of Testing in Software Development

By
Introduction 
Software testing is an essential part of ensuring application quality, stability, and reliability. Various testing types focus on different aspects of the application, each playing a critical role in delivering a robust product. Let’s explore four key types of testing:

1. Smoke Testing : Smoke testing involves performing quick checks to verify that the core functionalities of the application are working as expected. It acts as a preliminary test to catch critical issues early before more in-depth testing begins.

Purpose:
  • Validate that the build is stable enough for further testing.
  • Quickly identify severe issues that block further testing.
When to Perform:
  • After receiving a new build from the development team.
2. Sanity Testing: Sanity testing is a narrow and focused approach to verify that specific functionalities work correctly after minor changes or bug fixes.

Purpose:
  • Ensure that a small section of the application behaves as intended after a recent code change.
  • Validate that the fixes or updates did not introduce new issues.
When to Perform:
  • After receiving minor updates or patches.
3. Regression Testing: Regression testing is a comprehensive testing process to ensure that new changes, enhancements, or bug fixes have not adversely affected existing functionalities.

Purpose:
  • Confirm that recent changes did not introduce unintended side effects.
  • Maintain the stability of the application over time.
When to Perform:
  • After major code changes, such as adding new features or refactoring.
4. Retesting: Retesting focuses on verifying that specific defects have been fixed and are no longer reproducible.

Purpose:
  • Confirm the successful resolution of reported issues.
  • Ensure the application now meets the specified requirements.
When to Perform:
  • After receiving confirmation from developers that the defect has been resolved
Key Differences Between the Testing Types

1. Smoke Testing 
   - Purpose: Validates overall build stability.  
   - Scope: Broad, covering critical functionalities.  
   - Timing: Performed after receiving a new build.  
   - Automation: Often automated.  

2. Sanity Testing
   - Purpose: Verifies specific functionality after minor changes.  
   - Scope: Narrow and focused on recent updates.  
   - Timing: Conducted after bug fixes or minor updates.  
   - Automation: Primarily manual.  

3. Regression Testing
   - Purpose: Ensures new changes do not break existing features.  
   - Scope: Comprehensive, covering the entire application.  
   - Timing: Performed after major code changes or feature additions.  
   - Automation: Frequently automated for efficiency.  

4. Retesting
   - Purpose: Confirms that specific defects have been resolved.  
   - Scope: Limited to the fixed issues only.  
   - Timing: Performed after developers report defect fixes.  
   - Automation: Mostly manual, though automation is possible.

𝐐𝐮𝐢𝐜𝐤 𝐑𝐞𝐜𝐚𝐥𝐥:

- Smoke Testing : Quick checks to ensure the core functionalities of a web application are working.

- Sanity Testing : Focused checks on specific parts after minor changes or bug fixes.

- Regression Testing : Comprehensive checks to ensure new changes haven’t broken existing functionalities.

- Retesting : Re-checking specific issues to confirm they are fixed.

Purpose of the StepData Class in Selenium + Java Cucumber Automation Framework

By
When working with a Selenium + Java + Cucumber automation framework , one of the most common challenges testers face is sharing data between different step definitions within the same scenario. For example, a value created in one step—such as a login token or order ID—often needs to be reused in later steps. This is where the StepData class becomes extremely useful. In this blog, we will cover: What the StepData class is Why it is required in Cucumber frameworks How it is used in real-time automation projects Best practices for using StepData effectively What Is the StepData Class? The StepData class is a simple POJO (Plain Old Java Object) designed to store and share test data across multiple step definition classes within a single Cucumber scenario. It acts as a central data container that holds scenario-specific information during test execution. Why Do We Need StepData in Cucumber? Cucumber follows an object-oriented execution model, which creates certain limitations: Each st...

Ensuring Thread Safety in Parallel Test Execution with Selenium, Cucumber, and Java

By
🔒 What Is Thread Safety in Selenium Automation? When multiple threads (tests or scenarios) run simultaneously, they must not interfere with each other’s data or browser sessions. ⚠️ Example: Common Problem Without Thread Safety If your WebDriver is declared as: public static WebDriver driver; and you run tests in parallel, all tests share the same driver object — leading to several issues such as: 1️⃣ Browser windows closing unexpectedly 2️⃣ Wrong data being accessed by other tests 3️⃣ Screenshots captured from the wrong browser 4️⃣ Flaky or inconsistent test results 5️⃣ One test closing the browser while another is still running 6️⃣ Tests opening URLs in the same browser window 7️⃣ Random “Session not found” errors ➡️ Without thread safety, your parallel runs become unstable and unreliable. 💡 How To Achieve Thread Safety We can achieve thread safety using the ThreadLocal class in our automation framework. 🧰 What Is ThreadLocal? ThreadLocal provides each thread with its own copy of ...
