Object Mapping - Lab 1

1. Create the Simulation object

Steps

1. In the com.workshop package in the src/main/java folder, create a package called models
2. Create a Java class named Simulation in the com.workshop.models package
3. Add the following annotation on the top of the class name, from Lombok:
   • @Data
   • @Builder
   • @NoArgsConstructor
   • @AllArgsConstructor

4. Add the following private attributes and their type:

   type	name
   String	name
   String	cpf
   String	email
   BigDecimal	amount
   int	installments
   boolean	insurance

Expected results

• Simulation model class created within the correct annotations and attributes

package com.workshop.models;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.math.BigDecimal;

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class Simulation {

    private String name;
    private String cpf;
    private String email;
    private BigDecimal amount;
    private int installments;
    private boolean insurance;
}

2. Create the test for the POST request

Steps

1. Open the SimulationsTest in com.workshop.simulation in the src/test/java folder
2. Create a test method named shouldCreateNewSimulation()
3. Create a Simulation object using the builder method
4. Add the precondition using the following methods:
   • body(): add the simulation object as a parameter
   • contentType() add the ContentType.JSON from the REST Assured package
5. Add the post() request for the /simulations/ endpoint

Tips

• you can use the class name, followed by the builder() method, then the methods. Example: Simulation.builder().

Expected results

• Test partially created with the precondition (given()) and request (when()), without assertions, yet!

@Test
void shouldCreateNewSimulation() {
    var simulation = Simulation.builder().name("Elias").cpf("123456789")
        .email("elias@eliasnogueira.com").amount(new BigDecimal("3000"))
        .installments(5).insurance(true).build();

    given()
        .body(simulation)
        .contentType(ContentType.JSON)
    .when()
        .post("/simulations");
}

3. Addin the assertion for the POST request

Steps

1. In the shouldCreateNewSimulation() add the assert action (then()):
   • validate the status code as 201 (CREATED)
   • add the header() method using:
     • Location as the attribute to assert
     • CoreMatchers.containsString as the matcher, adding the CPF value
2. Run the test

Tips

• the code will look like

  .then()
     .statusCode(STATUS-CODE-HERE)
     .header("Location", CoreMatchers.containsString(SOMETHING-HERE));
  

• you can get the CPF value from the simulation object

### Expected results

• Green test execution where the following verifications will be performed successfully
  • status code
  • Header

@Test
void shouldCreateNewSimulation() {
    var simulation = Simulation.builder().name("Elias").cpf("123456789").email("elias@eliasnogueira.com")
            .amount(new BigDecimal("3000")).installments(5).insurance(true).build();

    given()
        .body(simulation)
        .contentType(ContentType.JSON)
    .when()
        .post("/simulations")
    .then()
        .statusCode(HttpStatus.SC_CREATED)
        .header("Location", CoreMatchers.containsString(simulation.getCpf()));
}
