How to mock Eureka when doing Integration Tests in Spring?

Question

I am running a simple Junit Testing a Controller in Spring Boot. The test code looks like this:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfigu         


        

Answer 1

You can set a system property for eureka.client.enabled=false for tests.

If you're running the tests using gradle you can do this:

tasks.withType(Test) {
    systemProperty 'eureka.client.enabled', 'false'
}

If you're running tests in an IDE then you'll have to set the system property there as well.

Answer 2

Another solution is to disable the Eureka Client in your application.properties or application.yml file under test/resources

applications.properties:

eureka.client.enabled=false

application.yml:

eureka: client: enabled: false

This has the benefit of not needing to remeber to include the system property for every JUnit test that requires disabling the Eureka Client.
