About initial build and unit test

[ahmetakman]

During the installation procedure, for the build command pyb -E unit there happened a bunch of Assertation and Type errors while executing the unit tests from Python modules.
Then the info occurs as Executed 180 unit tests and All unit tests passed. According to the error this happens in run_spk. Then build system gives same errors and Infos 3 times.

Just after that the system warn about some test coverages are below 70%.
[INFO] Overall lava-nc coverage is 72%
[INFO] Overall lava-nc branch coverage is 66%
[INFO] Overall lava-nc partial branch coverage is 91%

Finally, there occurs the error " BUILD FAILED - Error while executing setup command ['bdist_dumb']. " and build finishes.

I am using Python 3.9.6
Windows 10.
Intel I7 9750H

What could have caused this build error sequence what can be the solution?

Thanks,

Hi @ahmetakman thanks for the question.

Can you try to run the unit tests directly python -m unittest and report back the results?

I have a feeling the pybuilder virtual environment is not working correctly on your system. Sometimes this can be caused by path limitations on Windows. We need to update all of our docs to running the unit tests directly rather than through pyb.

I have removed all the setup and tried a clean one. But, I noticed that I had not done the build step successfully. Unfortunately, for the pip install e . command, I am getting the same error BUILD FAILED - Error while executing setup command ['bdist_dumb']. . Then even though running unit test on failed build unnecessary, I have tried to run unit test, and it has failed all of them naturally.

BTW I am using the home directory, I do not know whether you mean that by path limitation.

Sorry for the late answer, but the problem still continues.

I am on way to solve the problem, the virtual environments does not get activated with the command given in the instruction in Windows Powershell, instead I have used python3_venv\Scripts\activate and it (seems) succesfully activated the environment. But, the build fails again with the same error while it was preparing meradata for build wheel.

Hi, I am having the same error when using pyb and directly by running python -m unittest. The result when running the latter is the following:

Hi @PaoloGCD. Thanks for your question. It sounds like your issue is different than the OP. Have you tried the install solution in the FAQ https://github.com/lava-nc/lava/wiki/Frequently-Asked-Questions-(FAQ)#install ?

[PaoloGCD]

Thank you, yes my problem was the max number of files.
