/**
* {@code @SetSystemProperty} is a JUnit Jupiter extension to set the value of a
* system property for a test execution.
*
* The key and value of the system property to be set must be specified via
* {@link #key()} and {@link #value()}. After the annotated method has been
* executed, the original value or the value of the higher-level container is
* restored.
*
* {@code SetSystemProperty} can be used on the method and on the class level.
* It is repeatable and inherited from higher-level containers. If a class is
* annotated, the configured property will be set before every test inside that
* class. Any method-level configurations will override the class-level
* configurations.
*
* During
* parallel test execution,
* all tests annotated with {@link ClearSystemProperty}, {@link SetSystemProperty}, {@link ReadsSystemProperty},
* and {@link WritesSystemProperty} are scheduled in a way that guarantees correctness under mutation of shared global
* state.
*
* For more details and examples, see
* the documentation on @ClearSystemProperty and @SetSystemProperty.
*
* @since 0.5
