Vagrant won't run nosetests under ssh -c

[Kevin Engle]

I wanted to write a command to ssh into vagrant, change the current working directory, and then run nosetests.

I found in the documentation for vagrant that this could be done with vagrant ssh -c COMMAND

http://docs.vagrantup.com/v2/cli/ssh.html

The problem is I'm getting different results if I run nose through -c or manually after SSH.

Command:

vagrant ssh -c 'pwd && cd core && pwd && nosetests -x --failed' web




Output:

/web
/web/core

----------------------------------------------------------------------
Ran 0 tests in 4.784s

OK
Connection to 127.0.0.1 closed.

Commands:

vagrant ssh web

/web$ pwd && cd core && pwd && nosetests -x --failed

Output:

/web                                                     
/web/core

I don't understand why it makes a difference.

I haven't made any progress on this issue.

Hi Kevin,

I'm no nose expert, but it might help to increase the verbosity of nosetests with the -v flag to see if it provides any more clues. Based on the output that you posted, I can't see why the two invocations would be different.

Hi Chris,

Running it with -v produces no additional output on the vagrant -c box:

$ vagrant ssh -c 'pwd && cd core && pwd && nosetests -v -x --failed' web
/web
/web/core

----------------------------------------------------------------------
Ran 0 tests in 13.182s

OK
Connection to 127.0.0.1 closed.

Unfortunately on the manual box it just adds more information about the individual tests.

testA (myapp.tests.testFile.testClass) ... ok
testB (myapp.tests.testFile.testClass) ... ok
etc.

Thanks,
Kevin

In case someone else runs into this, I was able to resolve the issue.

I changed my command to vagrant ssh -c 'cd core && nosetests -x --failed --exe' web.

It still isn't clear to me why it makes a difference between -c and manually going into the box, but it works now.
