Unit test do not work with Anaconda/Python3 on Ubuntu (WSL)

[agodemar]

I generate makefiles for JSBSim with CMake on ubuntu within my WSL (Windows System for Linux) box on Windows. I have Anaconda installed with Python 3.6.4.

This is what I do:

Not sure offhand about the release issue. In terms of the python3 issue have you installed Anaconda into WSL/Ubuntu or have you installed it into Windows?

I've done all my Jsbsim python testing in Windows using VS2017's built in CMake support.

[agodemar]

I have Anaconda into WSL/Ubuntu. This is my Ubuntu version:

The module __release__ is part of cxxtest and should be installed under /usr/lib/python3.6/site-packages/cxxtest/__release__.py. If it is not then it is likely that something went wrong during the installation of cxxtest.

And BTW these unit tests were on my drive for years. The move to Travis and AppVeyor CI made me take the plunge.

[seanmcleod]

@bcoconni I was wondering how come you added these. Wasn't sure if it was because of some specific limitation with the Python test setup.

@seanmcleod

Wasn't sure if it was because of some specific limitation with the Python test setup.

The idea was to have a pure C++ unit test suite in addition to the Python test suite which is more an integration test suite in my view.

[seanmcleod]

Okay in terms of using CxxTest on AppVeyor it looks like we either need to get it installed or at least configured. From the latest AppVeyor build:

-- Could NOT find CxxTest (missing: CXXTEST_INCLUDE_DIR CXXTEST_PYTHON_TESTGEN_EXECUTABLE) 

[bcoconni]

@agodemar
The AppVeyor interface has been updated to clone and build CxxTest on Windows.
May be you can use it to fix your problem ?

jsbsim/appveyor.yml

Lines 23 to 29 in 574f855

	build_script:
	# Install CXXTest for C++ unit tests
	- git clone --depth=10 --branch=4.4 https://github.com/CxxTest/cxxtest.git
	- set PATH=%CD%\cxxtest;%PATH%
	- cd cxxtest\python
	- python setup.py install
	- cd ..\..

This is now fixed since commit eecc318
