APIs and microservices are key catalysts in integrating systems and extending the reach of existing services. Having a forward-thinking strategy for testing APIs and microservices is essential. The Infosys API Testing services help enterprises accelerate their journey to becoming cloud-ready with a robust and comprehensive API testing framework.

Infosys has a comprehensive approach that ensures high-quality APIs and microservices for successful digital transformation, integration, and continuous validation services for enterprises. Extensive integration coverage and tools-driven techniques are adopted to validate the implementations of API management gateways, message-oriented middleware (MOM), integration platform as a service (IPaaS), enterprise service bus (ESB), and migrations to new platforms.

Looking for next-gen API/Microservices testing solutions?


The Infosys API Testing practice helps enterprises with a three-pronged strategy:


  • A fully automated approach to validate functional and non-functional conformance of APIs enabling continuous integration and delivery
  • Adoption of shift-left, low-code/no-code and self-healing methodologies to accelerate high-quality delivery
  • AI-powered and cognitive techniques to optimize and cost-effectively deliver solutions with adjacent focus on performance and resilience


Infosys API Test Automation: A lightweight cloud-agnostic platform powered by AI and self-healing features, this solution accelerates testing in both traditional and modern API/microservices-based SOA architecture.


With leading industry tool/software vendors like CA, IBM, HP, Parasoft, etc., Infosys provides joint go-to-market solutions and customized pricing models as well as training and enablement programs.

This strategy helps enterprises achieve an over 50% reduction in testing efforts, cost savings of up to 40% through early defect detection, and 40% cycle time reduction.


Challenges & Solutions

Infosys API Test Automation is a scalable and portable framework that supports progressive functional automation. It can be integrated into a continuous testing environment, making it ideal for agile and DevOps models. This helps accelerate time to market.

Progressive automation at unit level and reuse for system and regression tests.

Infosys Test Virtualization Solution provides uninterrupted availability of enterprise landscape by virtualizing various layers, such as services, data, environment, and devices. Infosys Smart Virtualization workbench accelerates project lifecycle by enabling smarter test environments through virtualization across the application landscape and technologies. Our Service Virtualization solution in conjunction with market-leading commercial and open-source tools reduces dependencies on provider systems.

A customized non-functional approach is used to validate performance and scalability of services early in the software development lifecycle. This can help improve confidence among providers as well as consumers. Performance assessments focus on ensuring infrastructure scalability and also that the services are resilient. This helps enhance customer experience.

Security testing of services can be performed early in the development process by using infrastructure as code (IaC) static code review. This is done as part of a DevSecOps approach, which integrates security testing into the development and deployment process. Static application security testing (SAST) and dynamic application security testing (DAST) are leveraged to automatically scan the code for vulnerabilities. Software composition analysis (SCA) is used to identify vulnerabilities in third-party dependencies.
