// test initialization: complex test with 4 pipelines
// Take a task with the following set of pipelines for example:
//
// pipeline 0 pipeline 1 pipeline 2 pipeline 3 ... pipeline id
// partitioned unpartitioned partitioned unpartitioned ... partitioned/unpartitioned pipeline
// grouped grouped grouped ungrouped ... execution strategy (in grouped test)
// ungrouped ungrouped ungrouped ungrouped ... execution strategy (in ungrouped test)

// CrossJoin-A ..... Build-A Values-3
// | |
// Scan-0 CrossJoin-B .... Build-B
// (effectively ExchangeSink) |
// | Scan-2
// Values-1
// (1 row)
//
// CrossJoin operator here has the same lifecycle behavior as a real cross/hash-join, and produces
// the correct number of rows, but doesn't actually produce a cross-join for simplicity.
//
// A single task can never have all 4 combinations: partitioned/unpartitioned x grouped/ungrouped.
// * In the case of ungrouped test, this test covers driver with
// 1) split lifecycle (partitioned ungrouped)
// 2) task lifecycle (unpartitioned ungrouped)
// These are the only 2 possible pipeline execution strategy a task can have if the task has ungrouped execution strategy.
// * In the case of grouped test, this covers:
// 1) split lifecycle (partitioned grouped)
// 2) driver group lifecycle (unpartitioned grouped)
// 3) task lifecycle (unpartitioned ungrouped)
// These are the only 3 possible pipeline execution strategy a task can have if the task has grouped execution strategy.
//
// The following behaviors are tested:
// * DriverFactory are marked as noMoreDriver/Operator for particular lifespans as soon as they can be:
// * immediately, if the pipeline has task lifecycle (ungrouped and unpartitioned).
// * when TaskSource containing the lifespan is encountered, if the pipeline has driver group lifecycle (grouped and unpartitioned).
// * when TaskSource indicate that no more splits will be produced for the plan node (and plan nodes that schedule before it
// due to phased scheduling) and lifespan combination, if the pipeline has split lifecycle (partitioned).
// * DriverFactory are marked as noMoreDriver/Operator as soon as they can be:
// * immediately, if the pipeline has task lifecycle (ungrouped and unpartitioned).
// * when TaskSource indicate that will no more splits, otherwise.
// * Driver groups are marked as completed as soon as they should be:
// * when there are no active driver, and all DriverFactory for the lifespan (across all pipelines) are marked as completed.
// * Rows are produced as soon as they should be:
// * streams data through as soon as the build side is ready, for CrossJoin
// * streams data through, otherwise.
