pls find the dependencies details below

   dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:3.3.6")
        classpath 'org.owasp:dependency-check-gradle:8.2.1'
    }    //Testing
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation("org.junit.jupiter:junit-jupiter")
}

when upgradeing the spring boot version to 3.4.0 in parent build.gradle file the test cases were not able to run for one of the dependent service, how to sort out this issue.

Answer 1

It looks like this issue was resolved in spring boot 3.4.2 - Release Notes

It includes this bug fix in the changelog

NoClassDefFoundError when using JUnit to test a Gradle 7.6.x app that depends on spring-boot-actuator-autoconfigure but not on org.junit.platform:junit-platform-launcher #43340

Answer 2

I encountered this and created a bare bones Spring Boot 3.4 project using Spring Initializer for version 3.4 Java 17 and noticed that it included this test runtime dependency:

testRuntimeOnly 'org.junit.platform:junit-platform-launcher'

I included this in my project and it was then able to locate the missing class and my tests started executing
