Basic HTTP testing of Vespa applications

Vespa provides a robust framework for testing HTTP interfaces of applications through its CLI, which includes a test command enabling developers to create and execute basic HTTP tests using JSON format. This feature simplifies the process by managing endpoint discovery and authentication, allowing developers to concentrate on testing, while the Vespa Cloud's Continuous Deployment (CD) framework supports these tests to ensure safe and straightforward deployment to production. Developers can begin by installing and configuring the Vespa CLI, cloning the sample app, and deploying the application either locally or in the cloud, followed by running system tests. For production deployment in Vespa Cloud, tests can be modified and submitted, with additional guidance available in the reference documentation.
