"No tests found for given includes" when running Gradle tests in IntelliJ IDEA

Question

I cannot run tests via Gradle in IntelliJ IDEA because of "No tests found for given includes" error.

How can I fix it?

GradleTests

import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.assertTrue;

public class GradleTests {
    @Test
    public void initTest() {
        assertTrue(true);
    }
}

build.gradle

plugins {
    id 'java'
}

group 'org.example'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    //testCompile group: 'junit', name: 'junit', version: '4.12'

    // https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-api
    testCompile group: 'org.junit.jupiter', name: 'junit-jupiter-api', version: '5.6.0'
}

test {
    useJUnitPlatform()
}

Error:

> Task :test FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':test'.
> No tests found for given includes: [GradleTests.initTest](filter.includeTestsMatching)

Some notes:

• Issue is reproduced with both JUnit 4 and 5
• IntelliJ IDEA 2019.3.3 (Community Edition), Build #IC-193.6494.35, built on February 11, 2020
• Test is in src/test/java
• changing runner like Intelij 2019.1 update breaks JUnit tests didn't help
• without useJUnitPlatform() result is the same

Thanks to Ben Watson I've found solution. Since JUnit 5.4.0 there is aggregate artifact with both api and engine dependencies. So just adding one dependency to build.gradle resolved this issue.

testCompile ('org.junit.jupiter:junit-jupiter:5.6.0')
