The Best Way to implement e2e testing for my java spring micoservices
Hey there! Let's talk about testing your Java Spring microservices in a way that's super easy to understand! 😊
What You'll Need:
- TestContainers (for managing test databases and services)
https://www.testcontainers.org/ - REST Assured (for testing API endpoints)
https://rest-assured.io/ - Cucumber (for writing tests in plain English)
https://cucumber.io/
Step-by-Step Guide:
- Add these dependencies to your pom.xml:
<dependency>
<groupId>org.testcontainers</groupId>
<artifactId>testcontainers</artifactId>
</dependency>
<dependency>
<groupId>io.rest-assured</groupId>
<artifactId>rest-assured</artifactId>
</dependency>
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-java</artifactId>
</dependency> - Create a test class:
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class E2ETest {
@Test
public void testMyService() {
given()
.when()
.get('/api/myendpoint')
.then()
.statusCode(200);
}
}
Cool Tips:
- Always test your services together as they would run in real life
- Use Docker containers for your databases during testing
- Write your tests in a way that's easy to read and understand
