This test calls "nmcli g" with a bogus D-Bus bus address. We expect
a failure on stderr.
On alpine:latest, the error however looks slightly different:
b'size: 258\nlocation: src/tests/client/test-client.py:test_offline()/1\ncmd: $NMCLI g\nlang: C\nreturncode: 1\nstderr: 136 bytes\n>>>\nError: Could not create NMClient object: Key/Value pair 0, *invalid*, in address element *very:invalid* does not contain an equal sign.\n\n<<<\n'
On ubuntu:16.04 and debian:9 we got:
b"size: 258\nlocation: src/tests/client/test-client.py:test_offline()/1\ncmd: $NMCLI g\nlang: C\nreturncode: 1\nstderr: 136 bytes\n>>>\nError: Could not create NMClient object: Key/Value pair 0, 'invalid', in address element 'very:invalid' does not contain an equal sign.\n\n<<<\n"
On fedora and most recent systemd we got:
b'size: 258\nlocation: src/tests/client/test-client.py:test_offline()/1\ncmd: $NMCLI g\nlang: C\nreturncode: 1\nstderr: 136 bytes\n>>>\nError: Could not create NMClient object: Key/Value pair 0, ?invalid?, in address element ?very:invalid? does not contain an equal sign.\n\n<<<\n'
This depends on the glib version (whether to print `%s', '%s', or “%s”).
Also, as we run the application with lang=C, so that libc (I think)
replaces Unicode with an ASCII character. Here musl and glibc behave
differently.
Workaround by replace the unexpected text.
Let the replace_arr parameter of Util.replace_text() only contain
callables, and don't special case the argument. Previously, we
either expected a regex or a 2-tuple, and the code would check
each explicitly.
Aside that the tuples are hard to follow, it also makes
Util.replace_text() strongly tied to those types. By instead accepting
and arbitrary function, each element can implement its own replacement.
Also, make text that was replaced by regex atomic. Meaning, if we
first match (and replace) a certain part of the text with the regex,
then the replacement cannot be split again. This is done by returning
a 1-tuple from the replace function.
Seems the previous code did not work properly:

Set extra variables after the pre-defined ones have been set. This
allows overriding then.
In particular, this allows overriding DBUS_SESSION_BUS_ADDRESS so that
the test can check the behavior of the client is correct when it's set
to some garbage.
We now get unit test failures hitting this timeout. That is
likely a new bug introduced somewhere, but to rule out that
the timeout is simply too short, increase it.
Note that "test-client.py" currently only tests nmcli. But what it does
is to spawn test-networkmanager-service.py and run nmcli against it.
As such, it could really be used to test any NetworkManager client
against the stub service. Hence this test is not under
"src/nmcli/tests", but under "src/tests/client/" where it is more
general.
