These extensions were built as a JUnit5 equivalent for some of the functionality provided by the popular System Rules library. The port to JUnit5 extensions is WIP there, so this acts as a go between, borrowing a good chunk of the currently implemented logic, but omitting the fluent builder. There are no tests at the moment for any of the logic here.
The extensions included here are:
SystemPropertiesExtension: for modifying System Properties. It reverts all modifications after each test.EnvironmentVariablesExtension: for modifying Environment Variables. It reverts all modifications after each test.
