"/opt/flocker/bin/trail [test]" failed in scratch flocker installation

[shay-berman]

Hello

I installed flocker 1.15 (by the instruction mentioned here)
The I install my flocker driver successfully but when I try to run the flocker driver test, I get this error (exceptions.ImportError: No module named mimic.tap):
I though that clean Flocker installation allows to run /opt/flocker/bin/trial [test] out of the box.
Do I miss something?

here is the full error:

/opt/flocker/bin/trial ibm_storage_flocker_driver.test_ibm_storage_flocker_driver
ibm_storage_flocker_driver

Ran 1 tests in 0.003s

FAILED (errors=1)

If i run
#> /opt/flocker/pip install -r https://github.com/ClusterHQ/flocker/blob/master/requirements/flocker-dev.txt

it install all the dependences and the /opt/flocker/bin/trial [test] running well.

If customer wants to run the driver test, he will have to install the flocker-dev.txt first, is it acceptable?
I though all the dependencies should come with scratched flocker installation.

Thanks

Thanks @shay-berman

You're right. If we encourage people to run the tests on packaged Flocker we should include all the dependencies required to run the tests.

[shay-berman]

In order to run the driver test in production Flocker node, you need to install the following dependencies(in redhat):

yum install enchant gcc python-devel openssl-devel
/opt/flocker/bin/pip install -r /tmp/flocker-dev.txt
#Then the /opt/flocker/trial [driver test] will work

If you encourage customers to run the trial test immediate after installing Flocker driver, then I guess we should fine easier way to run it.
Any suggestions?

@wallrj is this just a documentation update or does this sound more like maybe a re-organize of the requirements would help

We probably need to re-organise our requirements files.
The enchant library is only required because we include the sphinx spellcheck extension in flocker-dev.txt

Instead, that should probably be separated out into requirements/docs.txt along with the Python dependencies that are required for building the docs.

Also note that @vchernoy and I have been discussing packaging Flocker as a Docker image only, in which case, all the Python and OS dependencies would be included in the Docker image and the tests could be run from inside the Docker container.
