Comparing two textual Files

I have written a function to compare two text files. When I run the test of the function,I do not get the expected results. The problem is that when I run the test, I get "Not Necessary to compare files" printed in the results of all the test cases.

% Initialize outputs testStatus = 1; testMessage = {};

% Open, read each line (row) and close the first text file FID = fopen(File1, 'r'); % Opens the first (reference) text file File1 for reading Data = textscan(FID, '%s', 'delimiter', '\n', 'whitespace', ''); % Reads File1 data into a cell array Data lines1 = Data{1}; % Returns the first line of cell array of strings Data to lines1 fclose(FID); % Close the opened first file

% Open, read each line (row) and close the second text file FID = fopen(File2, 'r'); Data = textscan(FID, '%s', 'delimiter', '\n', 'whitespace', ''); lines2 = Data{1}; fclose(FID);

% Get the number of elements in cellOneData1 and cellOneData2 numElOfLines1 = numel(lines1); % Number of elements in array cellOneData1 numElOfLines2 = numel(lines2); % Number of elements in array cellOneData2

% Compare the content the cell arrays cellOneData1 and cellOneData2 for i=1:numElOfLines1

    if i <= numElOfLines2
        if strcmp(lines1{i},lines2{i})== 1

        else
            testStatus = 0;
            outText = ['Line ' num2str(i) ':' ' ' lines1{i} ' Is different from: ' lines2{i}];
            testMessage{end+1} = sprintf(outText);
        end
    else 
        if i > numElOfLines2                    % If number of lines in lines1 is more than that of lines2
            testStatus = 0;
            outText = 'Not Necessary to Compare the Files';
            testMessage{end+1} = sprintf(outText);
            return;
        end
    end 
end
