# This test aims at testing various operations after getting rid of an inferior
|
|
# that was running in background, or while we have an inferior running in
|
|
# background. The original intent was to expose cases where the commit-resumed
|
|
# state of the process stratum target was not reset properly after killing an
|
|
# inferior running in background, which would be a problem when trying to run
|
|
# again. The test was expanded to test various combinations of
|
|
# run-control-related actions done with an inferior running in background.

# - start: use the start command
