Subject: Tests: snapshot tests complain that nothing is output
X-Git-Tag: v2.12.14~6
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=887d5ddfd89a4f20f02c03c015c81c18ba261e6f;p=lttng-tools.git

Tests: snapshot tests complain that nothing is output

The user space snapshot tests invoke a common script that runs the
actual tests. In doing so, the parent script's tap generator isn't
involved in the production of the tests' tap output and outputs an error
message as diagnostic.

  ok 134 - Wait after kill session daemon
  # Looks like your test died before it could output anything.

`exec`-ing the common script sidesteps the problem by replacing the
shell entirely.
