Using tox.ini to define env variables with dynamic values

Question

I want to leverage use of markers to run the pytest suite. The flow being as below:

• Specify the list of markers in a config file
• Read this parameter in the tox.ini file and dynamically use it during runtime
• Will be using jenkins to automate the test suite I understand it is possible to have static parameters in the tox.ini file Official document

Is it possible to have these parameters read from another file ?

Using pll's example from this this thread

 [main]
    ignore_list = "E201,E202,E203,E221,E231,E241,E265,E266,E272,E402,W293,W391"
# to be read from another file
    
    [testenv]
    commands =
        pep8 \
        --max-line-length=120 \
        --ignore={[main]ignore_list}    

Answer 1

Instead of directly calling pep8, you can create a bash script which reads the ignore list and then builds the command and finally runs it.
