unable to test (win 10)

[ozkey]

Created a fresh new app and was unable to run "npm test" (Windows 10)

mern init newAPP
cd newApp
npm install

it looks like it tries to run a linux script in (\node_modules.bin\acorn)

the error:

D:\development\newAPP>npm test

Update: Tried this on Windows 7 and got same result as expected.
It looks like this build is Linux / Mac only

[brandon-arnold]

To fix this, I removed the npm --harmony-proxies portion from the "test" command in package.json, and added a --serial flag to the end.

package.json:

    "test": "cross-env NODE_ENV=test PORT=8080 MONGO_URL=mongodb://localhost:27017/mern-test node_modules/.bin/nyc node_modules/.bin/ava --serial",

I'm not sure what the purpose is of npm --harmony-proxies in this command; can the maintainer explain it? This --serial seems to be required when performing the testing upon git commit.

At any rate, in Windows this is the reason for the errors: npm is processing the ava (bash) script as Javascript. Hence dirname is undefined. The node_modules/.bin folder actually has two scripts, ava which is bash and ava.cmd which is a DOS batch file; so it is node_modules/.bin/ava.cmd that gets called on Windows using the above configuration.

[brandon-arnold]

I should also mention that there was a resulting "TypeError: callback is not a function" from mongodb-prebuilt after I did this, which is a known issue with that package. I got it working as described here, but obviously this is sub-optimal.

[ozkey]

Fixed
Thank you

Why is this closed? The bug is still present!

@OscarKlintrot: Probably because it's a duplicate of open issue #201.

[OskarKlintrot]

@brandon-arnold: No, they are only related (as the author writes). I don't get the error in #201, only this one. Looks more like the author was satisfied with the help he got rather than that the bug got fixed. npm --harmony-proxies has now been changed to node --harmony-proxies but that is still causing the same problem. I guess that someone has put some thought behind it so I don't really want to create a PR either. Or maybe I'll can and see what the programmers says about it, maybe it isn't needed.

[OskarKlintrot]

I guess --harmony-proxies is to be able to run the tests on Node <v6.x.x: https://travis-ci.org/Hashnode/mern-starter/jobs/173191479. That explains why I didn't get the error, I'm using Node v6.2.2. This should hopefully be fixed when #221 is fixed.

[acooley]

I'm also getting this error and I'm on the very latest version of node (7.1.0), so I don't see that this has been fixed. I've applied the suggested changes and that does resolve the issue, but these seem like pretty fundamentally important command line arguments to me. This bug should be re-opened.

[OskarKlintrot]

@ozkey: Can you reopen this issue?

I am also experiencing this issue.

This works in windows 7. But it runs tests serially instead in parallel.

"scripts": {
    "test": "cross-env NODE_ENV=test PORT=8080 MONGO_URL=mongodb://192.168.99.100:27017/mern-test node_modules/.bin/nyc node_modules/.bin/ava --serial",

If I run the tests without the "--serial" option they will hang indefinitely at the end.

What concerns me are also the warning messages.

npm run test

> cross-env NODE_ENV=test PORT=8080 MONGO_URL=mongodb://192.168.99.100:27017/mern-test node_modules/.bin/nyc node_modules/.bin/ava --serial
