Verify Element Count

Create a Flux emitting 1 through 100 and verify it emits exactly 100 elements using StepVerifier. Use expectNextCount(). Print "Count test passed!".

expectNextCount(n) skips n elements without asserting their values.

Expected

Count test passed!

Create a Flux emitting 1 through 100 and verify it emits exactly 100 elements using StepVerifier. Use expectNextCount(). Print "Count test passed!".

expectNextCount(n) skips n elements without asserting their values.

Why this works

expectNextCount(n) expects exactly n elements to be emitted without verifying their values. This is useful when you care about the quantity but not the specific content of each element.

Expected output

Count test passed!
