So, in brief:

I have a method that is void, and prints stuff to standard output.

I have a second file that tests the output of functions against what it should be and returns true if they all pass.

I have a makefile that checks the output of the test file to make sure that all the tests passed.

My problem is that I don't know how to compare the void method's printed output against what it should be in the test file. I was told to modify the make file, but I don't know how. My other tests for methods with return types look something like this:

```
private static boolean testNumFunc() {
    if (MainFile.numFunc(300) == /*proper int output*/) {
        return true;
    }
    return false;
}

```

How would I test a void function this way by modifying the makefile?
