I don't get why #26039 is closed, but I think my use case is valid. I use WebTestClient to write integration tests (using my own library based on spring-cloud-wiremock) to test servlet-based applications. There are no mocks at all and I'm not gonna use MockMvc, the sample is the following:

@SpringBootTest(
    webEnvironment = WebEnvironment.RANDOM_PORT,
    classes = SampleApplicationTest.SampleApplication.class)
@TestPropertySource(properties = "server.servlet.context-path=/test")
class SampleApplicationTest {

  @Autowired
  private TestRestTemplate testRestTemplate;
  @Autowired
  private WebTestClient webTestClient;

  @Test
  void shouldReturnResources() {
    var actual = testRestTemplate.getForEntity("/resources", String.class);
    assertThat(actual.getStatusCode()).isEqualTo(OK);
    assertThat(actual.getBody()).isEqualTo("test-resource");


    webTestClient.get().uri("/resources").exchange()
        // will fail with 404 cos context path is not configured
        .expectStatus().isOk()
        .expectBody(String.class).isEqualTo("test-resource");
  }

  @SpringBootApplication
  static class SampleApplication {

    static void main(String[] args) {
      SpringApplication.run(SampleApplication.class, args);
    }

    @RestController
    static class Controller {
      @GetMapping("/resources")
      String resources() {
        return "test-resource";
      }
    }
  }
}

I'd like to have possibility to configure baseUrl for WebTestClient, so I can allow consumers of the library to use either TestRestTemplate or WebTestClient using the same url. Currently there is no way to customize base path for WebTestClient.
