"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

Answer 1

I had this error with a similar setup, but couldn't solve it with the previous answers. Resolved it by doing this.

1. File > Setting (Ctrl+Alt+S)
2. Build, Execution, Deployment > Build Tools > gradle
3. Run Tests using: Intellij IDEA
