Subject: [PATCH v6 10/13] convert: generate large test files only once
Date: Thu, 25 Aug 2016 13:07:49 +0200 [thread overview]
Message-ID: <20160825110752.31581-11-larsxschneider@gmail.com> (raw)
In-Reply-To: <20160825110752.31581-1-larsxschneider@gmail.com>
From: Lars Schneider <larsxschneider@gmail.com>
Generate more interesting large test files with pseudo random characters
in between and reuse these test files in multiple tests. Run tests
formerly marked as EXPENSIVE every time but with a smaller data set.
