FPCUnit on MacOS (/Catalina)
« on: October 16, 2020, 02:15:37 pm »
I run my FPCUnit tests using the GuiTestRunner on OSC, and when I click on go, I get an error:

[Debugger Exception Notification]


[Break]
Project MarkdownTestProgram raised exception class 'EFCreateError' with message:
Unable to create file \"MarkdownTestProgram.fpcunit.ini\": Read-only file system

 At address 1000173E0


[Ignore this exception type]

[Continue]

I'm compiling to the application bundle - I don't seem to have any choice about that? (I can't find any other way that it works).

The problem occurs at this line of code:

  FConfStore := TIniFile.Create(ExtractFileNameOnly(ParamStr(0)) + '.fpcunit.ini'); // Prevent ini file names conflict if tests are embedded in application

in GuiTestRunner. I don't have any control over the ini file, and I don't seem to have any options to make that location writeable (finder says that I have read/write access to the folder, but apparently not in practice.

Has anyone else run into this, and figured out what to do?

It sounds like you are trying to write to the system volume which is read-only (since Catalina), hence the error "Read-only file system".

Using ParamStr(0) is not advised under any UNIX operating system for a whole host of reasons best summarised in the Multiplatform Programming Guide. That link will also direct you to details on how and where to store your ini file on macOS.

function GetRandomNumber: integer; // xkcd.com
begin
  GetRandomNumber := 4; // chosen by fair dice roll. Guaranteed to be random.
end;
