"""Shared test setup: repo-root imports, headless Qt, pyueye stub.
|
|
|
|
The IDS uEye SDK (pyueye + libueye) only exists on the Linux rig. On any
|
|
other machine we stub the module before hardware.uc480_camera is imported;
|
|
everything in uc480_camera references `ueye.*` at call time, not import
|
|
time, so an attribute-permissive dummy is sufficient for constructing
|
|
windows and importing modules.
