Redmine

test/test_helper.rb attempts to delete the PDF files in tmp/test/pdf before running tests:

FileUtils.rm Dir.glob('#$redmine_tmp_pdf_directory/*.pdf')

Because the pattern is enclosed in single quotes, $redmine_tmp_pdf_directory is not interpolated, and Dir.glob always returns an empty array. As a result, the PDF files saved by the save_pdf helper are never deleted.

The attached patch fixes this by using a double-quoted string.
