"""Rebuild tests with esp-idf-configdep enabled (default idf.py behavior).
|
|
|
|
esp-idf-configdep rewrites compiler .d files to depend on per-option
|
|
build/config/.../*.cdep stubs instead of sdkconfig.h. The tests in
|
|
test_rebuild.py disable configdep to exercise pure CMake/Ninja incremental
|
|
behavior. Here we keep configdep **on** and apply the same coarse-grained
|
|
checks as the classic rebuild tests (plus relaxed expectations where configdep
|
|
legitimately skips compiling TUs that do not reference changed CONFIG_* symbols).
