java.lang.NoClassDefFoundError: org/springframework/cloud/test/TestSocketUtils after upgrading Spring Boot version to 3.x

Issue

I am using the below given dependency in the build.gradle for application tests:

testImplementation 'org.springframework.cloud:spring-cloud-starter-contract-verifier:4.0.1'

Now when I updated the Spring Boot version from 2.x to 3.x, I am getting java.lang.NoClassDefFoundError for TestSocketUtils.

Wondering if anyone has got this issue before?

Solution

Please add spring-cloud-test-support dependency in build.gradle:

testImplementation 'org.springframework.cloud:spring-cloud-test-support:4.0.1'

This has the org.springframework.cloud.test.TestSocketUtils class in it.
