+# This is to test that the steampipe binary can be symlinked and still function correctly.
+# This is important for Homebrew and other package managers that may symlink the binary.
+# We had a failure in v2.0.0 where the symlinked binary left over steampipe plugin processes
+# running in the background, due to a pluginmanager bug. 
+# This test ensures that the symlinked binary works properly and does not leave any processes
