Subject: [PATCH] test: Implement self-test functionality
|
||
|
|
|
||
|
|
This allows to run 'test' unattended by setting environment variable
|
||
|
|
SELFTEST=on. Instead of printing the settings libkeepalive should have
|
||
|
|
changed, it uses the input values still present in environment to assert
|
||
|
|
them being set correctly.
|
||
|
