Cant run the test class "No tests found with test runner 'Junit5'"

I've created a simple Maven java application in which I am trying to run the Test case.

when doing run as JunitTestCase it gives a popup window stating that "No tests found with test runner 'JUnit5'".

and on console:

Java.lang.NoClassDefFoundError: org/junit/platform/engine/TestEngine

my pom.xml has :

 <dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>5.7.1</version>
    <scope>test</scope>
</dependency>

as well as using: org.junit.jupiter.api.Test

PS:- I am already using JUnit5 annotations. and with "Run as maven-test" zero tests were run is coming.

You only depend on the api, giving you e.g. the annotations, but you are missing the engine to execute your tests. Either add junit-jupiter-engine as dependency or switch to the convenience dependency junit-jupiter.

Look at the maven starter sample (https://github.com/junit-team/junit5-samples/tree/r5.7.1/junit5-jupiter-starter-maven), on how to get a minimal functional pom.xml for junit5.
