From 791afae2924d032186bfad557c462c92025ac901 Mon Sep 17 00:00:00 2001 From: Ævar Arnfjörð Bjarmason Date: Thu, 3 Feb 2022 22:40:13 +0100 Subject: progress.c tests: make start/stop commands on stdin MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Change the usage of the "test-tool progress" introduced in 2bb74b53a49 (Test the progress display, 2019-09-16) to take command like "start" and "stop" on stdin, instead of running them implicitly. This makes for tests that are easier to read, since the recipe will mirror the API usage, and allows for easily testing invalid usage that would yield (or should yield) a BUG(), e.g. providing two "start" calls in a row. A subsequent commit will add such tests.
