Create a Flux of 2, 4, 6, 8 and use StepVerifier with assertNext() to verify each element is even. Print "Assert test passed!" after verification.

assertNext() lets you run custom assertions on each element.

Esperado

Assert test passed!

Custom Assertions

Create a Flux of 2, 4, 6, 8 and use StepVerifier with assertNext() to verify each element is even. Print "Assert test passed!" after verification.

assertNext() lets you run custom assertions on each element.

Why this works

assertNext() accepts a Consumer that can run arbitrary assertions on the next emitted element. If the assertion fails, the StepVerifier will report the failure.

Expected output

Assert test passed!
