103 Delete Configurations
104 [Documentation] Delete all elements that were created in the test case section. These are done
105 ... in a local keyword so this can be called as part of the Suite Teardown. When called as part
106 ... of the Suite Teardown, all steps will be attempted. This prevents robot framework from bailing
107 ... on the rest of a test case if one step intermittently has trouble and fails. The goal is to attempt
108 ... to leave the test environment as clean as possible upon completion of this suite.
