No vanilla JUnit dependency in spring-boot-starter-test?

Ram :

I created a brand new (Gradle, Java Language, Boot 2.2.6, Jar & Java 11) project in start.spring.io (no dependencies specified). I expected to see vanilla JUnit (junit:junit:x.xx) dependency in the testing classpath. But do not find it.

Executing ./gradlew dependencies does not include the vanilla JUnit but only org.junit.jupiter:junit-jupiter. Please see the relevant output below.

The default generated test (DemoApplicationTests.java) only has an import org.junit.jupiter.api.Test; instead of import org.junit.Test.

What am I missing? The complete build.gradle is included below for easy reference.

Thomas Kläger :

org.junit.jupiter:junit-jupiter is JUnit, although in version 5.x.

The vanilla junit:junit dependency that you seem to expect is the older JUnit version 4.x
