* Update apache_conf test to check for ServerAlias values. Signed-off-by: Miah Johnson <miah@chia-pet.org> * Add ServerAlias key and values to mock apache conf which includes trailing whitespace. Signed-off-by: Miah Johnson <miah@chia-pet.org> * Updated test to reflect all ServerAlias values being put into a single array item. This is expected as we do not override the key_values default setting of '1' when passing the raw configuration to SimpleConfig. Signed-off-by: Miah Johnson <miah@chia-pet.org> * Update the regular expression to include a conditional with positive lookahead that checks if the line ends with one or more spaces. If the lookahead succeeds we non-greedily capture, and when it fails we greedily capture. Signed-off-by: Miah Johnson <miah@chia-pet.org>
