Upgrading from JUnit 3.7 to 3.8

Recently had to upgrade an entire codebase from 3.7 (very old) to 3.8.1 (quite old) The main annoyance was a contructor that's no longer needed, just gets in the way.

Search Pattern

public class $CLASS$ extends $TESTCASE$ {
    
     public $CLASS$(String name) {
         super(name);
         $constructor$
     }
     
     $content$
}

Variables

TESTCASE = junit.framework.TestCase , replace in type hierarchy = true
constructor = min 0, max unlimited
content = min 0, max unlimited

Replacement Pattern

public class $CLASS$ extends $TESTCASE$ {
     
     public void setUp() throws Exception {
         $constructor$
     }
     
    $content$
}

Removing empty setUp()

Search Pattern

public class $CLASS$ extends $TESTCASE$ {
    
    public void setUp() throws Exception {
        
    }
          $content$
}

Variables

TESTCASE = junit.framework.TestCase
content = min 0, max unlimited

Replacement Pattern

public class $CLASS$ extends $TESTCASE$ {
    $content$
}

Tidy Up

Then just need to fix manual calls to constructors of the test classes (shouldn't be many...)

Remove empty constructors

Search Pattern

public class $CLASS$ $extends$ {
    
     public $CLASS$() {}
       
     $content$
}

Variables

content - unlimited
extends - unlimited

Replace Pattern

public class $CLASS$ $extends$ {
       
     $content$
}
