  • Purpose: Ensures UI consistency and detects visual defects, which helps maintain a visually coherent user experience.

  • Tools:

    • Applitools: An AI-powered visual testing and monitoring platform.

    • Percy: A visual testing tool that captures screenshots and compares them to baseline images.

  • Snapshot Testing

Snapshot testing captures the current state of the application’s UI and compares it against previous states to detect any changes. It helps identify UI changes that may have occurred due to recent code changes.

  • Purpose: Detects UI changes and regressions, ensuring that the UI remains consistent and as intended throughout development cycles.

  • Tools:

    • Jest: A JavaScript testing framework that includes built-in snapshot testing capabilities.

    • Storybook: An open-source tool for developing UI components in isolation for React, Vue, and Angular. It supports snapshot testing for UI components.

  • Functional Testing

Functional testing is critical in verifying that the software functions as intended and ensuring that all features and functionalities work according to the specified requirements. This type of testing tests the functional aspects of the application to ensure it behaves as expected. It focuses on the output generated by the software for a given input and aligns with the system's functional requirements.

  • Purpose: Validates the application against functional requirements, ensuring each function performs as specified. It helps identify discrepancies between the expected and actual output.

  • Tools:

    • Selenium: An open-source tool for automating web browsers, widely used for functional testing of web applications.

    • QTP (QuickTest Professional): Now known as UFT (Unified Functional Testing), it is a popular functional and regression testing tool.

    • TestComplete: A comprehensive tool for functional testing that supports various scripting languages and integrates with CI/CD tools.

  • Performance Testing

Performance testing evaluates an application's performance characteristics under various conditions to ensure it operates efficiently and effectively. It tests the application’s performance under various conditions, including different load levels and stress scenarios. It measures the system's responsiveness, stability, scalability, and speed.

  • Purpose: Identifies performance bottlenecks and ensures the application can handle expected loads, maintaining acceptable performance levels under peak conditions.

  • Tools:

    • JMeter: An open-source tool designed for load testing and measuring performance.

    • LoadRunner: A performance testing tool from Micro Focus that simulates virtual users to test application performance under load.

    • Gatling: An open-source load testing framework based on Scala, Akka, and Netty.

  • Fuzz Testing

Fuzz testing is a security-focused technique that provides the application with random and invalid data inputs to uncover vulnerabilities and bugs. Provides random data inputs to the application to find vulnerabilities and bugs. Automated testing services are beneficial for identifying security issues and robustness problems.

  • Purpose: Detects security issues and ensures robustness by finding unexpected crashes, memory leaks, and other failures.

  • Tools:
