Top 10 Microservices Testing Tools In 2024
Microservices testing involves testing each microservice separately and with other services. A microservices architecture comprises a collection of services, each working independently and relying on APIs to communicate with other services. The underlying architecture of microservices influences the techniques available for decoupling a microservice from its dependencies for testing purposes.
Testing microservices is slightly more complex than testing monolithic applications. So, teams need to understand microservices testing strategies like performance, contract, and others to ensure the system functions as intended. Besides these testing strategies, your team must embrace the right microservice automation testing tools for desired testing outcomes.
