ChatGPT is a computer program designed to understand and generate human-like text. It can be used for tasks such as language translation, text generation, and creating chatbots. It's a type of Artificial Intelligence model, more specifically it's a language model, that can understand and generate text.
Developers can leverage their coding skills thanks to chatGPT.
Let's see one use case: the generation of a unit test
I first ask chatGPT to generate a Java bean with this prompt (a prompt is a command to give to chatGPT):
Write a Java bean to store a postal address. Use the Lombok annotations to have constructors, getters, setters, and builders.
chatGPT in reply gave me:
import lombok.Builder; import lombok.Getter; import lombok.Setter; @Builder @Getter @Setter public class Address { private String street; private String city; private String state; private String zip; private String country; }
which is great ✅👍
Now, let's ask to generate the unit test with the following prompt:
Write a Junit test that tests every fields of the Java bean from the snippet below import lombok.Builder; import lombok.Getter; import lombok.Setter; @Builder @Getter @Setter public class Address { private String street; private String city; private String state; private String zip; private String country; }:
chatGPT replies with:
import org.junit.Test; import static org.junit.Assert.assertEquals; public class AddressTest { @Test public void testAddressFields() { Address address = Address.builder() .street("123 Main St") .city("Anytown") .state("CA") .zip("12345") .country("USA") .build(); // Test street field assertEquals("123 Main St", address.getStreet()); // Test city field assertEquals("Anytown", address.getCity()); // Test state field assertEquals("CA", address.getState()); // Test zip field assertEquals("12345", address.getZip()); // Test country field assertEquals("USA", address.getCountry()); } }
which is great ✅👍
Then I pasted it to IntelliJ and it worked fine. Great job chatGPT! 👏
