I'm trying to create an application similar to an online judge, but all I want is that after submitting a java file through an html page or jsp, the application runs a certain JUnit test case in that java file and shows the results in a new page. I'm having trouble figuring out the best way to do this, since I know that we can run JUnit tests in java files that are already inside the project, but I do not know how to do it in a java file that is to be submitted in the database. application. Does anyone know of anything that can help me?

Regardless of the security involved, this can even be easy. However, do not try to run within your application.

Create an empty project (no classes) in any directory on the server that has the required dependencies, in this case JUnit. I suggest using Maven.

Ensures that you have JDK and Maven available on the command line

Create an empty class template and provide it to users if needed.

Each time someone submits a class:

Create a single temporary directory ( File.createTempFile )

Run another process in the temporary directory with the command mvn test . Maven should compile the class and run the test class automatically.

The test results are inside the target/surefire-reports folder.

If you want a bit of security, probably a Docker image and the Maven Docker Plugin to run the tests safe and secure way. However, this will require a little more research and configuration of the system to work well.
