Comparing file contents cross platform

I have a file that has been created on Windows, so it has carriage returns "\r\n".

The file is used in a test, the contents of the file are compared to the contents of a file that is generated during the test. The test passes on Windows because the generated file has the same carriage return.

But the test doesn't pass on Unix/Mac.

It fails because the generated file has linefeeds, ie. only "\n".

Can any one advise how to deal with this?

Edit: The test is a JUnit (Java) test.

I ended up not using a real file, and had the test create the file on the platform at runtime using the system property to get the platforms line terminator.

You can try the following to avoid reading line by line with

String text = FileUtils.readFileAsString(filename)
                       .replaceAll("(\r\n|\r|\n)", "\n");

This replaces all new-lines of any type with "\n"

  • You could compare files reading them line-by-line
  • You could have two different sample files for unix/windows
