You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: MOxUnitFieldTripTestCase.m
    path of file: ./repos/fieldtrip/contrib/MOxUnit_fieldtrip/@MOxUnitFieldTripTestCase
    
    the code of the file until where you have to start completion: function obj=MOxUnitFieldTripTestCase(fn)
% Initialize MOxUnitFieldTripTestCase instance
%
% obj=MOxUnitFieldTripTestCase(filename)
%
% Inputs:
%   filename                Filename of .m file with FieldTrip test
%
% Output:
%   obj                     MOxUnitFieldTripTestCase representing the
%                           case in the filename.
%
% Notes:
%  - unlike its MOxUnitFunctionHandleTestCase superclass, this class
%    represents a test case through a single function in an mfile.
%    Running the tests involves 'cd'-ing to the directory where the mfile
%    is stored, and then calling the function.
%  - the 'get' function can be used to get 'mem', 'walltime', or 'dccnpath'
%    properties

    % while running the test.
    % The current approach uses 'findobj' to find the figures open both
    % before and after running the test, and then closes the ones that were
    % present in the latter but not the former list using 'setdiff'.
    % This approach works under Octave and Matlab, even though findobj
    % returns a numeric vector in Octave and a Figure object in Matlab.
