Testing gRPC APIs with Postman
Blog post from Postman
Postman has enhanced its support for gRPC APIs by introducing a robust testing capability, enabling users to write test specifications for all use cases within its familiar interface, similar to testing REST APIs. This development aims to streamline API development and testing processes by providing a user-friendly environment that incorporates a Javascript-based scripting feature, allowing for the creation of both standard and custom tests. Users can easily navigate through the testing process with the help of pre-curated code snippets for common scenarios, while more complex tests can be crafted using the full range of pm.* APIs, including the capability to validate messages against JSON schemas. The improvements extend across various gRPC methods, facilitating comprehensive test specifications within Postman, and further developments are anticipated, including the introduction of saving examples, automatic mock servers, and automated testing workflows.
