Subject: Fix: test cases now rely on explicit workloads
X-Git-Tag: v2.7.6~1
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=6fff952b4d4abb22adb01637843d26c31997916a;p=lttng-tools.git

Fix: test cases now rely on explicit workloads

Run a process explicitly in the tracing session to generate the enabled events
rather than relying on the events generated by the lttng CLI.
