StepVerifier Basics

Write a StepVerifier test for a Flux emitting "A", "B", "C". Verify each element in order, then verify completion. Print "Test passed!" at the end.

StepVerifier is the standard way to test reactive streams in Project Reactor.

Write a StepVerifier test for a Flux emitting "A", "B", "C". Verify each element in order, then verify completion. Print "Test passed!" at the end.

StepVerifier is the standard way to test reactive streams in Project Reactor.

Why this works

StepVerifier subscribes to a Publisher and lets you assert expectations step by step. expectNext() verifies the next emitted element. verifyComplete() asserts the stream completed without error.

Expected output

Test passed!
