What is Automated Testing?

Automated testing is the process of using software tools to execute pre-scripted test cases on a software application to validate its functionality, performance, and reliability. Unlike manual testing, where testers need to run tests step by step, automated testing streamlines this process by automating repetitive tasks, which improves software quality assurance and reduces time-to-market.

Types of Automated Testing

Understanding the different types of automated testing helps teams tailor their testing strategy to their application’s unique needs. Below are the key categories of testing, each serving a specific purpose:

1. Functional Testing

Functional testing is a type of software testing that evaluates the functionality of a software application to ensure it meets the specified requirements. It focuses on verifying that each feature of the application works as expected by providing the appropriate inputs and verifying the outputs. This includes validating workflows, business logic, and core functionalities. For instance, in an e-commerce app, functional testing ensures that adding items to the cart, processing payments, and order confirmation work seamlessly.

Functional testing is typically conducted using test automation frameworks like Selenium, which can simulate user interactions across various browsers. This ensures that the software behaves as expected under real-world conditions.

2. Non-Functional Testing

Non-functional testing is a type of software testing that evaluates the non-functional aspects of a software application, such as performance, usability, reliability, and scalability. Unlike functional testing, which focuses on what the system does, non-functional testing checks how well the system performs under various conditions. For example:

Scenario:

A popular e-commerce website expects a surge in traffic during a Black Friday sale.

Testing Approach:

• Conduct load testing to simulate thousands of users browsing and purchasing items simultaneously.
• Perform stress testing to check how the website behaves under peak loads beyond expected capacity.
• Measure response time, page load speed, and transaction processing speed.

Expected Outcome:

• The website should handle 10,000 concurrent users without crashing.
• The checkout process should complete within 2 seconds under heavy load.

By incorporating non-functional testing into the automation strategy, teams can guarantee not only functional accuracy but also a smooth and secure user experience.

3. Smoke Testing

Smoke testing validates the critical functionalities of a software build. It acts as the initial checkpoint to determine if further testing is viable. For instance, after deploying a new feature in a ride-sharing app, smoke tests confirm that users can book a ride, view driver details, and track their journey. As one of the essential types of automated testing, smoke testing ensures quick feedback on the stability of core features.

This type of testing is highly automated due to its repetitive nature. It ensures that core features are stable before more detailed tests like end-to-end testing are executed.

4. Keyword-Driven Testing

Keyword-driven testing involves creating test scripts based on predefined keywords that represent specific actions. This method simplifies automation by enabling non-technical team members to contribute. For instance, in a banking app, keywords like "Login" or "Transfer" correspond to detailed test steps executed automatically.

Using tools with built-in automated test scripts, keyword-driven testing enhances collaboration and improves test coverage metrics across teams.

5. Data-Driven Testing

Data-driven testing ensures robustness by running the same test scripts with multiple sets of data inputs. For example, verifying login functionality with different user credentials ensures the application performs reliably under various scenarios.

Tools like Katalon Studio excel in data-driven testing, enabling testers to define datasets and validate results efficiently, which is critical for Agile testing automation workflows.

6. End-to-End Testing

End-to-end testing examines the entire application workflow, from user inputs to back-end processes. This type of testing ensures that all components of the software interact as expected. For instance, in an online booking system, end-to-end tests validate the entire process from searching for a flight to payment and ticket generation.
