Passing an extremely long filter to dotnet test?

I am trying to pass an extremely long filter to dotnet test --filter. However, it is so long, that I get a "path too long" error.

Is there any other way to specify a filter?

Or alternatively somehow "pipe" a filter from a file into the --filter argument with dotnet test?

Solution

  • It is a OS limitation. not much you can do about it.

    See: Exec and (very) long commands on Windows

    cmd.exe has a maximum command-line length limit of 8191 characters
    Win32's CreateProcess has a maximum lpCommandLine length of 32,768 characters.

    Workaround

    See: Command prompt (Cmd. exe) command-line string limitation

    Modify programs that require long command lines so that they use a file that contains the parameter information, and then include the name of the file in the command line.
