When the check-methods are used for the first time you will see the below warning in the logs. This means you don't need to combine the save- and check-methods if you want to create your baseline.

#####################################################################################
 Baseline image not found, save the actual image manually to the baseline.
 The image can be found here:
 /Users/wswebcreation/project/.tmp/actual/desktop_chrome/examplePage-chrome-latest-1366x768.png
 If you want the module to auto save a non existing image to the baseline you
 can provide 'autoSaveBaseline: true' to the options.
