Test failing in Debug mode

• Platform: x86_64 GNU/Linux
• Subsystem: test

The test for addons/repl-domain-abort is failing, when configure was run in debug mode:

./configure --debug && make -j48 test

The assertion in the test test/addons/repl-domain-abort/test.js fails:

/usr/bin/python tools/test.py --mode=release -J \

With some debug statements, turns out the binding module cannot be found:

Error: Cannot find module '/usr/local/google/home/franzih/node/test/addons/repl-domain-abort/build/Debug/binding'

Should build/Debug be created or should the correct path be build/Release/binding?

I think the issue with that particular test is that it looks at the default_configuration whereas most other add-on tests simply load the the binding.node from a hard-coded path. Does this patch fix the issue for you?

As mentioned, most tests use a hard-coded path but that is arguably wrong: node-gyp builds add-ons in debug mode when a) --debug is passed, or b) the node binary used to build it is a debug build; the latter is something of a historical artifact.

IOW, build/Debug is the correct path some of the time but the tests don't currently respect it.

Thanks, that fixes it. I can't figure out how to generate build/Debug. I thought BUILDTYPE=Debug would do that.

[bnoordhuis]

You have to pass --debug on the command line or npm_config_debug=1 in the environment.

I don't mean to high jack this issue but it is somewhat related. I had an issue getting the add-on tests to run again after configured with --debug. What I mean is that I re-ran ./configure without the --debug option to generate a Release build.

My issue was that when running the tests, the build-addons target would not update the addon's config.gypi which still referred to "default_configuration": "Debug". To force an update I deleted test/addons/.buildstamp, and this allowed me to run the tests.

Should the removal of test/addons/.buildstamp perhaps be part of a target like clean or distclean?

@danbev I'm having similar issues. Especially after switching back from older branches.

@fhinkel Good to know that it is not just me :) I'll create a PR with a suggestion for handling.
