+  As an author
+  I want to see toast message in the CMS when I create, edit, delete, publish, unpublish, archive a record
+
+  Background:
+    Given the "Company" "Company A" with "Category"="Other" 
+    And the "Company" "Company B" with "Category"="Other"
+    And the "Company" "Company C" with "Category"="Other"
+    And the "Employee" "Employee A" with "Company"="1"
+    And the "Employee" "Employee B" with "Company"="1"
