hello, any idea how to verify JSON response from WebTestClient to check if fields are null? e.g.

testClient.get()
    .uri("whatever")
    .accept(APPLICATION_JSON)
    .exchange()
    .expectStatus().isOk
    .expectBody()
    .jsonPath("$.whatever").isEqualTo(null) // NULLABILITY_MISMATCH_BASED_ON_JAVA_ANNOTATIONS

If I enable

jsr305=strict

compiler settings the above fails complaining it expects non-null

Any

Are you returning

null

or are you just asserting that the field isn't there?

response has explicit null

You could probably use :

.json("""{"whatever":null}""")
