The pattern for the file names ensures the files are displayed in the expected order up to and including gigabytes, 10 digits. I added more test cases that the original test had to verify the displayed size is rounded up, an automatic test can easily verify more rows than a human can.

The test compares the size displayed in the table to the expected one. If it doesn't match, an error is printed to `stderr`. All the file sizes are verified. The first error message, if any, is thrown to fail the test.
