How to conditionally run TestMethodSetup functions

Hello,

I have setup a simple Class-based unit testing:

  properties
    CASE
    A
    B
    X
  end

  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
  %                              Parameterization                             %
  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


  properties (ClassSetupParameter)
    sc = {0, 1};
  end

  properties (MethodSetupParameter)
    ni = {123, 789, 987};
    nj = {123, 789, 987};
    nk = {123, 789, 987};
    da = {0.01, 0.1};
    db = {0.01, 0.1};
    dx = {0.01, 0.1};
    
    rr = {0, 1};
  end

  properties (TestParameter)
    ri = {23, 33, 100};
    rj = {23, 33, 100};
    rk = {23, 33, 100};
  end

  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
  %                                Class setup                                %
  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

  methods(TestClassSetup)
    function setupPerRun(testCase,sc)
      CASE = sc;
    end
  end

  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
  %                                Method setup                               %
  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

  methods(TestMethodSetup)

    function setupRandomMatrices(testCase,ni,nj,nk,da,db,dx)
      testCase.assumeEqual(testCase.sc,0);
      testCase.A = sprand( ni,nk,da ) > 0;
      testCase.B = sprand( nk,nj,db ) > 0;
      testCase.X = sprand( ni,nj,dx ) > 0;
    end

    function setupSpecialMatrices(tc,rr)
      ni = 456;
      nj = 789;
      nk = 678;
      switch rr
        case 1   % SPECIAL CASE: EMPTY MATRICES
          tc.A = sparse( ni, nk );
          tc.B = sparse( nk, nj );
          tc.X = sparse( ni, nj );

        case 2   % SPECIAL CASE: FULL
          tc.A = sparse( ones( ni, nk ) );
          tc.B = sparse( ones( nk, nj ) );
          tc.X = sparse( ones( ni, nj ) );

      end

    end

  end

  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
  %                             'exhaustive' tests                            %
  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

  methods(Test)
    function testFun1(tc)
      % run one test per setup
    end

    function testFun2(tc,ri,rj,rk)
      % run multiple tests per setup
    end

  end
    

What I would to do, is run either one of the two TestMethodSetup functions, depending on the value of CASE. That is, create two separate class-based instatiations, one with CASE = 0 and one with CASE = 1 dfa and specify to either run the setupRandomMatrices or the setupSpecialMatrices. The current behavior, is an exhaustive creation of all combinations in both sc = 0 and sc = 1.

Is this available through MATLAB TestSuite, or should I create two independent Classes for the tests? Both tests will share the same test function, therefore I would prefere to be able to specify this within the class, to minimize re-write and maximize code reuse.

Hi Dimitris,

I would suggest that first you create a new method without test attributes and add the helper functions setupRandomMatrices and setupSpecialMatrices to it. Also, define sc as a property of the Test class. Then inside methods(TestMethodSetup) call the appropriate helper functions setupRandomMatrices or setupSpecialMatrices using if/else statment on test class property sc.

Hope this helps!
