From 4ab20b513e7279c5441db2bba7d326484668d2cc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Fri, 30 Jun 2023 19:03:54 +0100 Subject: [PATCH] tests/docker: add test-fuzz MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Running the fuzzer requires some hoop jumping and some problems only show up in containers. This basically replicates the build-oss-fuzz job from our CI so we can run in the same containers we use in CI.
