/**
 * This test verifies the correct operation of readers using StreamCuts. Concretely, the test creates two streams
 * with different number of segments and it writes some events (TOTAL_EVENTS / 2) in them. Then, the test creates a
 * list of StreamCuts that encompasses both streams every CUT_SIZE events. The test asserts that new groups of
 * readers can be initialized at these sequential StreamCut intervals and that only CUT_SIZE events are read. Also,
 * the test checks the correctness of different combinations of StreamCuts that have not been sequentially created.
 * After creating StreamCuts and tests the correctness of reads, the test also checks resetting a reader group to a
 * specific initial read point. The previous process is repeated twice: before and after scaling streams, to test if
 * StreamCuts work correctly under scaling events (thus writing TOTAL_EVENTS). Finally, this test checks reading
 * different StreamCut combinations in both streams for all events (encompassing events before and after scaling).
