A number of QEMU tests are written in Python, and may benefit
|
|
|
26ba25 |
from an untainted Python venv.
|
|
|
26ba25 |
|
|
|
26ba25 |
By using make rules, tests that depend on specific Python libs
|
|
|
26ba25 |
can set that rule as a requirement, along with rules that require
|
|
|
26ba25 |
the presence or installation of specific libraries.
|
|
|
26ba25 |
|
|
|
26ba25 |
The tests/requirements.txt is supposed to contain the Python
|
|
|
26ba25 |
requirements that should be added to the venv created by check-venv.
