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