Question

Hello StackOverflow Community,

I have this JUnit Tests that need to run a Server with the command mvn exec:java, and I need to delete the contents of a directory before the tests are executed. Otherwise, the JUnit test will fail. Is there any way I can include these steps into my source code?

You should use JUnit’s @BeforeClass notation which will be called before the first test starts to clean up the target directory. You should also use the commons-io library avoid unnecessary coding.

import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;
import org.junit.BeforeClass;
import org.junit.Test;


public class DeleteDirectoryTest {
    private static final String DIRECTORY_PATH = "C:/TEMP";

    @BeforeClass
    public static void cleanUp() throws IOException {
        FileUtils.deleteDirectory(new File(DIRECTORY_PATH));
    }

    @Test
    public void doSomeTest() {
        // Test code goes here
   }
}
