SpringFramework JUnit MergedAnnotations java.lang.NoClassDefFoundError

Try ro run some unit tests in a Java SpringBoot application.

The unit test I run is :

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Value;

import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;

import static org.junit.Assert.assertEquals;

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = {WebAppInitializer.class})
public class FilePropertyInjectionUnitTest {
   @Value("${geckoDir}")
   private String geckoDir;

   @Test
   public void whenFilePropertyProvided_thenProperlyInjected() {
      assertEquals(geckoDir,"C:\\GeckoDriver\\geckodriver.exe");
   }
}

And I got the following error:

java.lang.NoClassDefFoundError: org/springframework/core/annotation/MergedAnnotations

I am using ItelliJ as IDE .

I finally figure this one out.I had to upgrade spring-test dependency to version 5.2.8:

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <version>5.2.8.RELEASE</version>
        <scope>test</scope>
    </dependency>

I really went down the rabitt hole with this one
