Subject: tests: get the socket path from the X11 atom I3_SOCKET_PATH
X-Git-Tag: 4.0~14^2~48
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=49ea8059052d74d09ca4fb11e889340349813072;p=i3%2Fi3

tests: get the socket path from the X11 atom I3_SOCKET_PATH

The hard-coded socket paths are not useful when running the test suite in
parallel.
