@rajadilipkolli, I've converted the test method shouldFindCustomerHistoryById to use RestAssured instead of MockMvc. Here's the updated code:

@Test
void shouldFindCustomerHistoryById() throws Exception {
    Customer customer = customerList.getFirst();
    customerRepository.saveAndFlush(customer.setAddress("newAddress"));
    Long customerId = customer.getId();

    given()
        .baseUri("http://localhost")
        .port(port)
        .basePath("/api/customers/{id}/history")
        .pathParam("id", customerId)
        .queryParam("page", 0)
        .queryParam("size", 10)
        .queryParam("sort", "revision_Number,desc")
    .when()
        .get()
    .then()
        .statusCode(200)
        .body("data.size()", is(2))
        .body("totalElements", is(2))
        .body("pageNumber", is(1))
        .body("totalPages", is(1))
        .body("isFirst", is(true))
        .body("isLast", is(true))
        .body("hasNext", is(false))
        .body("hasPrevious", is(false))
        .body("data[0].entity.id", is(customer.getId()))
        .body("data[0].entity.name", is(customer.getName()))
        .body("data[0].entity.address", is(customer.getAddress()))

        .body("data[0].revisionType", is("UPDATE"))
        .body("data[0].revisionInstant", notNullValue());
}

Please ensure that you have the RestAssured dependency added to your project and configure the port variable to match the port used during testing. Let me know if there are any other adjustments or additional methods you would like to convert!

Customer customer = customerList.getFirst();
customerRepository.saveAndFlush(customer.setAddress("newAddress"));
Long customerId = customer.getId();

mockMvc.perform(get("/api/customers/{id}/history?page=0&size=10&sort=revision_Number,desc", customerId))
.andExpect(status().isOk())

.andExpect(jsonPath("$.totalElements", is(2)))

@rajadilipkolli, thank you for pointing out the missing configuration for RestAssured.port. I've updated the setUp method in the CustomerControllerIT test class to include setting the port for RestAssured. Here's the revised version:

New Learnings Added

Learning: The `@LocalServerPort` annotation is used in the `CustomerControllerIT` class to automatically inject the port that the server is running on in integration tests.

Note: Learnings are effective only in the context of specific code segments. To apply general coding guidelines, please configure review instructions.

Customer customer = customerList.getFirst();
Long customerId = customer.getId() + 10_000;

mockMvc.perform(get("/api/customers/{id}/history?page=0&size=10&sort=revision_Number,asc", customerId))
.andExpect(status().isNotFound())
.andExpect(header().string(HttpHeaders.CONTENT_TYPE, is(MediaType.APPLICATION_PROBLEM_JSON_VALUE)))

.andExpect(jsonPath("$.title", is("Not Found")))
.andExpect(jsonPath("$.status", is(404)))
.andExpect(jsonPath("$.detail").value("Customer with Id '%d' not found".formatted(customerId)));
