+notes about sourceCode/tests/
+
+May 30th 2021
+-----------------------------------------------------------------------
+
+1) sourceCode/tests includes unit tests about StackProfs features
+
+2 Directory naming convention:
+  . if the test uses Qt framework, its directory name includes '_Qt_' string
+  . if the test does not use the Qt framework, its directory name includes '_noQt_' string
+
+3) Test images and other test data are located in this repository: 
+   https://github.com/IPGP/stackprof
+  
+4) Content description
