I have a class written that extends Runner (org.junit.runner.Runner), which is a part of the junit-4.13.2.jar. I am trying to migrate to JUnit 5 without using the JUnit Vintage engine. Is there a counterpart for the same class in JUnit 5, i.e., is there a way to migrate completely to JUnit 5?

I am using junit vintage engine 5 because I would like to slowly migrate from my old test written for junit 3 and junit 4 to the junit 5 standard.
The dependency I am using is junit vintage engine 5.8.2, and no other.
When I run mvn test in the console, it correctly executes all tests in the console.
However, when I attempt to run a single test file from within my Eclipse IDE (latest version), the number of tests executed are 0/0. The run configuation for that file shows that runner junit 5 is used. The tests executed are 0/0.
Is there a way I can make the Eclipse IDE detect my tests again? Thank you!
The spring-boot-starter-test dependency adds both JUnit4 vs JUnit5 APIs
Is it OK if developers start using both and any?
Are there any problems expected when codebase have many both JUnit4 vs JUnit5 ?
I believe that is part of JUnit 5's vintage component that has backwards compatibility for JUnit 4
In my project I'm doing some cleanup and decided to move everything to JUnit5.
Till this time, I was using
#RunWith(JUnitPlatform.class)
Now I want to migrate it to #ExtendWith. Is there any equivalent for this JUnitPlatform.class in JUnit5?
You don't need it anymore when using junit 5.
In the junit documentation it states:
Annotating a class with #RunWith(JUnitPlatform.class) allows it to be run with IDEs and build systems that support JUnit 4 but do not yet support the JUnit Platform directly.
So since you are migrating to junit 5 I suppose your build system/IDE supports it. Hence, you don't need the annotation anymore.
Junit4 #RunWith has been replaced by #ExtendWith in JUnit5 as of content from https://www.baeldung.com/junit-5-runwith
I found information about migrating from JUnit to TestNG in general (here for example) and about working in IntelliJ IDEA with JUnit and TestNG separately, but nothing about migrating from JUnit to TestNG in IntelliJ IDEA itself.
Can anyone describe the steps required to do this?
What it the equivalent of using the #RunWith annotation for Junit 3.8? I've searched for a while on this, but Junit 3.8 is much older and I haven't been able to find much on the subject. We are using a 1.4 jre so Junit 4 is out of the question to use.
If I remember correctly we used to do our own TestRunner implementations that our suites extended.
Turns out we can use Junit 4 to execute tests with Junit 3.8 by using the Junit38ClassRunner which is included in Junit 4.
