Subject: [PATCH 11/17] tests: Enable config override for tests
|
||
|
|
|
||
|
|
Some tests require to change kconfig symbols values to cover the code.
|
||
|
|
This patch enables one to set these vaues using <test-name>-config
|
||
|
|
variable.
|
||
|
|
|
||
|
|
Example for integer values.
|
||
|
|
timestamp-test-config += CONFIG_HAVE_MONOTONIC_TIMER=1
|
||
|
|
|
||
|
|
Example for string values. Notice escaped quotes.
|
||
|
|
spd_cache-test-config += CONFIG_SPD_CACHE_FMAP_NAME=\"SPD_CACHE_FMAP_NAME\"
