unit test for read and filter logfile

[Remi-Gau]

Actually, if you want to try writing a unit test, this function is perfect for it.

• isntall the mox unit toolbox on your computer
• create a tsv file with the some dummy content that the fucntion should read and filter (you can create and store it in a dummyData folder inside the tests directory.
• write a unit test function in the tests folder (see below for a template)

function test_suite = test_readOutputFilter %#ok<*STOUT>
    try % assignment of 'localfunctions' is necessary in Matlab >= 2016
        test_functions = localfunctions(); %#ok<*NASGU>
    catch % no problem; early Matlab versions can use initTestSuite fine
    end
    initTestSuite;
end

function test_readOutputFilterBasic()

    %% set up
   cfg = ... % fill in
   filterHeader = ... % fill in
   filterContent  = ... % fill in

   outputFiltered = readOutputFilter(cfg, filterHeader, filterContent)

   %% test data
   expectedOutput = ... % create a structure that describes what output you expect

    %% test
    assertEqual(expectedOutput, outputFiltered); % make sure they match

end
