Implement consumer-driven contract testing for Java microservices using the Pact framework
|
Learn how to test Java microservices with consumer-driven contracts in Open Liberty. Ensure effective communication between microservices with robust testing. Trustworthy end-to-end tests verify functionality from a user’s perspective, but GUI components like Selenium can be resource-intensive.

Learn how to test Java microservices with consumer-driven contracts in Open Liberty.
With a microservices-based architecture, you need robust testing to ensure that microservices that depend on one another are able to communicate effectively. Typically, to prevent multiple points of failure at different integration points, a combination of unit, integration, and end-to-end tests are used. While unit tests are fast, they are less trustworthy because they run in isolation and usually rely on mock data.
Usually, end-to-end tests are more trustworthy because they verify functionality from the perspective of a user. However, a graphical user interface (GUI) component is often required to perform end-to-end tests, and GUI components rely on third-party software, such as Selenium, which requires heavy computation time and resources.
