FAQPage Schema
How do I test reactive Spring Boot WebFlux endpoints?

Test reactive Spring Boot WebFlux endpoints by using WebTestClient to verify RESTful endpoint behavior, validation, security constraints, and error handling. This Skill provides testing patterns specifically for reactive @RestController endpoints to ensure proper response contracts.

What is the best way to verify security rules on Spring Boot WebFlux endpoints?

Verify security rules on WebFlux endpoints by using Spring Security test support integrated with WebTestClient. This approach allows you to test security constraints on reactive HTTP endpoints to ensure proper authorization and authentication behavior under various conditions.

Does WebTestClient work with Spring Boot 4 WebFlux applications?

Yes, WebTestClient works with Spring Boot 4 and WebFlux applications. This Skill requires Spring Boot 4 and WebFlux to test reactive HTTP endpoints, providing patterns for validating response contracts, security, and error handling in reactive RESTful applications.

How do I test validation errors and response contracts in a reactive Spring Boot application?

Test validation errors and response contracts in a reactive Spring Boot application by using WebTestClient with WebFlux. This Skill provides patterns to verify that reactive @RestController endpoints properly handle validation errors and adhere to expected response contracts.

Can I run WebFlux endpoint tests without manual configuration?

Yes, you can run WebFlux endpoint tests by executing the command ./scripts/test-webflux-endpoints.sh. This script automates the testing of reactive HTTP endpoints, simplifying the verification of endpoint behavior, security, and error handling in Spring Boot applications.

Why does my WebTestClient test fail to verify reactive endpoint behavior properly?

WebTestClient tests for reactive endpoints may fail if the application does not use Spring Boot 4 with WebFlux. This Skill requires Spring Boot 4 and WebFlux to properly test reactive @RestController endpoints, validation errors, security constraints, and response contracts.
