Performance Testing, Load Testing, Stress Testing, Volume Testing

 

🚀 Performance Testing

Performance Testing is a type of non-functional testing that evaluates the speed, stability, scalability, and responsiveness of a software application under a specific workload.

🔹 Goals:

  • Identify bottlenecks
  • Ensure the system meets performance benchmarks
  • Validate response time, throughput, and resource usage

Example: Testing how fast a banking app processes 10,000 concurrent transactions.

👥 Load Testing

Load Testing is a subset of performance testing that checks how a system behaves under expected or peak user loads. It simulates multiple users accessing the system simultaneously.

🔹 Purpose:

  • Validate system performance under normal and high traffic
  • Identify scalability limits and response delays

Example: Simulating 5,000 users shopping during a flash sale on an e-commerce site.

💥 Stress Testing

Stress Testing evaluates the system’s robustness and stability by pushing it beyond normal operational limits. It helps identify the breaking point and how the system recovers from failure.

🔹 Purpose:

  • Test system behavior under extreme load
  • Detect crashes, memory leaks, and recovery time

Example: Testing a result portal when 100,000 students try to access it simultaneously after results are announced.

🧱 Volume Testing

Volume Testing (also called Flood Testing) checks how a system performs when handling large volumes of data in the database or files.

🔹 Purpose:

  • Assess response time, data integrity, and storage handling
  • Identify issues like data loss, slow queries, or memory overflow

Example: Testing a music streaming app’s behavior when millions of songs are uploaded to the database.

What is an SDET? – Roles, Responsibilities, and Career Path

Introduction The field of software testing has evolved significantly, and with the rise of automation, the Software Development Engineer in Test (SDET) role has become crucial. SDETs are technical testers with strong programming skills who ensure software quality through test automation and continuous integration. But what does an SDET really do? Let’s dive in.   Key Responsibilities of an SDET An SDET wears multiple hats—part developer, part tester, and part automation engineer. Their primary responsibilities include: Developing test automation frameworks for functional and regression testing. Writing automated test scripts to validate application functionality. Collaborating with developers to ensure testability of code. Implementing CI/CD pipelines with automated testing for continuous deployment. Conducting performance, security, and API testing to enhance software robustness. Required Skills for an SDET To excel as an SDET, you need a mix of technical and so...

Keys.RETURN vs Keys.ENTER in Selenium: Are They Really the Same?

When you're automating keyboard interactions with Selenium WebDriver, you're bound to encounter both Keys.RETURN and Keys.ENTER . At a glance, they might seem identical—and in many cases, they behave that way too. But under the hood, there’s a subtle, nerdy distinction that can make all the difference when fine-tuning your test scripts. In this post, we’ll break down these two key constants, when to use which, and why understanding the difference (even if minor) might give you an edge in crafting more accurate and resilient automation. 🎹 The Subtle Difference On a standard physical keyboard, there are typically two keys that look like Enter: Enter key on the numeric keypad. Return key on the main keyboard (near the letters). Historically: Keys.RETURN refers to the Return key . Keys.ENTER refers to the Enter key . That’s right—the distinction comes from old-school typewriters and legacy keyboard design. Return meant returning the carriage to the beginning ...

Regression Testing vs. Sanity Testing: Detailed Explanation with Example

  Regression testing and sanity testing are both essential software testing techniques, but they serve different purposes in ensuring software stability after modifications. Regression Testing Definition: Regression testing is a comprehensive testing approach that ensures recent code changes do not negatively impact the existing functionality of an application. It involves re-running previously executed test cases to verify that the software still works as expected after modifications such as bug fixes, feature additions, or updates. Key Characteristics: Scope: Covers the entire application. Purpose: Ensures that new changes do not break existing functionality. Execution Time: Time-consuming due to extensive testing. Test Cases: Uses a large set of test cases. Automation: Often automated for efficiency. Depth: In-depth testing of all functionalities. When Used: After major updates, bug fixes, or new features. ...
