Trying to figure out how to run single test in fish

Makefile: 

.PHONY: test
test: build/fish
	$(CMAKE) --build build --target test

Tests.cmake: 

# CMake being CMake, you can't just add a DEPENDS argument to add_test to make it depend on any of
# your binaries actually being built before `make test` is executed (requiring `make all` first),
# and the only dependency a test can have is on another test. So we make building fish and
# `fish_tests` prerequisites to our entire top-level `test` target.
function(add_test_target NAME)
  string(REPLACE "/" "-" NAME ${NAME})
  add_custom_target("test_${NAME}" COMMAND ${CMAKE_CTEST_COMMAND} --output-on-failure -R "^${NAME}$$"
    DEPENDS fish_tests tests_buildroot_target USES_TERMINAL )
endfunction()

Aha, the -R argument.

Solution: 

cmake --build build --target test_tmux-complete.fish

For a test name tmux-complete.fish.


The error I'm getting doesn't seem to relate to the code I have changed... it seems to be completing a directory ~/temp when ~/file-1 and ~/file-2 should be the only options.

The following tests FAILED:

ninja: build stopped: subcommand failed.

Digging in to how that directory got there with: 

env fish_trace=1 FISH_DEBUG_OUTPUT=/tmp/debugfish.txt cmake --build build --target test_tmux-complete.fish

Which produces this output:

Which seems to wrap the call to littlecheck.py: 

-> python3 -S ../littlecheck.py --progress --force-color -s fish=../test/root/bin/fish -s fish_test_helper=../test/root/bin/fish_test_helper checks/tmux-complete.fish

Haven't figured out where this is running from to run it manually, yet.
