Webflux test in error: ApplicationContextException: Unable to start ReactiveWebApplicationContext due to missing ReactiveWebServerFactory bean - spring-test

Question

I am trying to factor out some mock bean configuration.
Here is the mock configuration:
#Configuration
public class PvgCacheMockConfiguration {
#Primary
#Bean
public PvgProjectClient pvgProjectClient() {
PvgProjectClient mock = Mockito.mock(PvgProjectClient.class);
when(mock.getAll()).thenReturn(generateMockProjects());
return mock;
}
private ValidationProjects generateMockProjects() {
ValidationProject validationProject = ValidationProject
.builder()
.id("anId")
.code("aCode")
.name("aName")
.projectResponsibleIpn("anIpn")
.batchForMilestone(MilestoneName.PPC)
.type(ValidationProjectType.VEHICLE)
.company(Company.builder().code("aCode").label("aLabel").build())
.withValidationPlanModule(false)
.build();
return ValidationProjects.builder().validationProjects(singletonList(validationProject)).build();
}
}
Here is how I try to import my configuration:
#RunWith(SpringRunner.class)
#SpringBootTest(
webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
properties = {"spring.main.web-application-type=reactive"})
#ActiveProfiles("test")
#Sql(scripts = {"classpath:reset.sql",
"classpath:sql/validationSupportNeedRepositoryTest/ValidationSupportNeedEntity.sql"})
#ContextConfiguration(classes = {PvgCacheMockConfiguration.class})
#AutoConfigureWebTestClient
public class ValidationSupportNeedControllerIntegrationTest {
...
Here is the stack trace when I run any test from the above test suite:
