Shift-left testing implementation

Shift-left testing brings quality assurance earlier in the development cycle. Rather than waiting until the end, your QA team engages from the initial stages of development. Indeed, this approach identifies and resolves bugs during code writing or review phases, making fixes infinitely more manageable.

At the same time, unit tests verify individual modules within applications, with external processes simulated or mocked. Similarly, API tests validate service endpoints, essentially becoming the new unit tests in microservices architectures.

Continuous testing frameworks

Continuous testing serves as the quality gatekeeper in the DevOps pipeline. In contrast to traditional methods, it introduces automated validation at every stage of development. JSONPath tester and other testing tools operate within this framework, ensuring consistent quality checks throughout the process. The framework encompasses various testing types, primarily focusing on:

• Automated functional tests for requirement verification
• Load and stress testing for performance optimization
• Security vulnerability scans
• Cross-platform compatibility checks

Continuous testing generates detailed reports containing issues or failures, enabling developers to make informed adjustments. In addition to these reports, the framework maintains thorough documentation to support self-learning testing models and risk mitigation strategies.

Modern Testing Infrastructure

Testing infrastructure has undergone substantial changes with the advent of cloud computing and containerization. The QA team now requires modern testing environments that support scalability and automation while maintaining cost efficiency.

Cloud-based testing environments

Cloud testing platforms provide access to thousands of real desktop and mobile devices for testing websites and apps in real time. First of all, these cloud-based testing environments eliminate the need for physical device labs, offering significant advantages:
