Hi@all,

I'm trying to build a unit test generator, but I dstruggle a little bit :/

planned steps:

Find the file to create the test for (input is filename)
Check if test folder exist or create them (based on package name)
copy and rename a prepared template file
rename the file name in the content
add all public methods as test methods with special naming and prefilled content
finsh

My problem is at the moment, if I change the content by using sth like this:

function renameFileNameContent(testPath, testName)
    [~, name, ~] = fileparts(fullfile(testPath, testName));
    fid = fopen(fullfile(testPath, testName), 'r');
    fileContent = rot90(StringConverter.ensureCharString(fread(fid, '*char')));
    fclose(fid);
    fileContent = regexprep(char(fileContent), testing.UnitTestSupport.TemplateName, name);
    fid = fopen(fullfile(testPath, testName), 'w');
    fprintf(fid, '%s', fileContent);
    fclose(fid);
end

The problem here is it's seems that the .m has meta data which are emtpy after this file recreation ...

My second try was sth like this:

function renameFileNameContent(testPath, testName)            
    fid = fopen(fullfile(testPath, testName), 'r');
    fileContent = rot90(StringConverter.ensureCharString(fread(fid, '*char')));
    fclose(fid);
    
    fileContent = regexprep(char(fileContent), testing.UnitTestSupport.TemplateName, name);
    editorService = com.mathworks.mlservices.MLEditorServices;
    editorApplication = editorService.getEditorApplication();
    editorApplication.newEditor(fileContent);
    openFiles = matlab.desktop.editor.getAll();
    
    %save(fullfile(testPath, testName), openFiles(length(openFiles)).Filename);
end
