 The first thing to notice in this test is that :attr:`~reframe.core.pipeline.RegressionTest.num_tasks` is set to zero as default, which is a requirement for flexible tests.
 However, with flexible tests, this value is updated right after the job completes to the actual number of tasks that were used.
