ROBOT_LIBRARY_SCOPE

ROBOT_LIBRARY_SCOPE has tree types of values.

TEST CASE

A new instance is created for every test case. A possible suite setup and suite teardown share yet another instance. This is the default.

TEST SUITE

A new instance is created for every test suite. The lowest-level test suites, created from test case files and containing test cases, have instances of their own, and higher-level suites all get their own instances for their possible setups and teardowns.

GLOBAL

Only one instance is created during the whole test execution and it is shared by all test cases and test suites. Libraries created from modules are always global.
