I am writing a program that does something based on information read<br>
from /proc (the target OS is linux). But I have some problems figuring<br>
out how to mock the /proc filesystem, or at least, some files in it.<br>
<br>
The rationale is that I want to change some files inside /proc to<br>
simulate different configurations of the host computer so that I can<br>
run my functional tests against those different configurations.<br>
<br>
I was thinking in using docker for this task. But<br>
1) this is offtopic here :)<br>
and<br>
2) I would like to learn what is the standard way to deal with such<br>
situations. If there is a "standard way" at all... I mean, what am I<br>
supposed to do from the point of view of TDD?<br>
<br>
I would appreciate if someone with experience in such problems could<br>
share some advice.<br>
<br>
Best,<br>
<br>
