Unit Testing For Matlab

Hi all,

I've released my Matlab unit testing toolbox MUnit at

http://xtargets.com/cms/index.php?option=content&task=view&id=19

It is trivial to use and comes with a ( IMHO ) a very nice browser based control panel and browser based reporting of test results.

The control panel and test report allows you to

* Run tests.
* Debug tests.
* Open the editor to the exact line where a test error occured.
* See the full details of the assertion that failed.
* Create new test cases using a test generation wizard
* bookmark tests for easy access

The test file format is very simple and follows the standard unit test pattern of fixture setup and teardown with a number of tests. Using matlab nested functions this becomes extremely powerfull.

///////////////\\\\\\\\\\\\\\

function test = test_template

    % Subclass the testcase object
    test = munit_testcase;

    % Create a structure of constraint objects for assertions
    c = munit_constraint;

    function setup
        % This function will be called at the
        % start of *every* test_ function

    end

    function teardown
        % This function will be called at the
        % end of *every* test_ function
    end


    % TEST_1
    %
    % This is an example test. Create new tests by creating
    % new functions whose name starts with test_
    function test_1

        % Assert that 1 == 1 to pass
        test.assert( c.eq( 1, 1 ) );

        % Assert that ~(1 == 1) to fail
        test.assert( c.not ( c.eq( 1, 1 ) ) );
    end
end

Note this toolbox requires Matlab Service Pack 3 due to a few feature enhancements Mathworks made.

Happy testing

PS. There is a bonus toolbox which you must install which is a text templating engine I used to generate the HTML reports for MUnit. It can be used for any text based generation and is much like PHP or Velocity but uses the Matlab language. Use it to generate HTML, XML, C-Code, M-Code etc etc.

eg: ------------------------------------------

    # function mtemplate_usecase1(rows)
         <html>
             <body>
                # for i = 1:rows
                    <%=genline(i)%>
                # end
             </body>
         </html>

         # function genline(row)
             <p> <%= 1:row %> </p>
         # end

     #end

  -------------------------------------------


 >> f = mtemplate_compile('mtemplate_usecase1.mt');
 >> f(3)
      ans =

      <html>
          <body>
              <p> 1 </p>
              <p> 1  2 </p>
              <p> 1  2  3 </p>
          </body>
      </html>
