Every file gets added a \n even when line endings are set to \r\n.

The problem seems to be in:

let formattedCode = formatter(fileName, content, formatOptions);
if ((<any>formattedCode).trimRight) {
    formattedCode = (<any>formattedCode).trimRight();
    formattedCode += formatOptions.NewLineCharacter;
}

( https://github.com/vvakame/typescript-formatter/blob/master/lib/index.ts#L110 )

When I change it to use formatOptions.NewLineCharacter, the tests fail as it looks like all expected results are in \n and not honouring the formatter settings (the json files) accompanying the test files.

I also notice some more replaces solely on \n. Are you internally converting everything to \n and when writing the result file convert it to the wanted line ending?
