Subject: Tests: Count number of chunk using ls
X-Git-Tag: v2.11.0-rc1~276
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=c7f643372d3d23515781191cce9731aeffdf2ea0;p=lttng-tools.git

Tests: Count number of chunk using ls

Instead on removing validated chunk and validate that the directory is
empty, count the number of chunk present at the beginning and validate
that the count is equal to three.

Let the caller take care of cleaning up the generated files.
