Command sctestgen generates test files for sctest.

BackupRollbacks tests that the schema changer can handle being backed up any time during any rollback of a failed schema change.

BackupRollbacksMixedVersion is like BackupRollbacks but in a mixed-version cluster which is upgraded prior to restoring the backups.

BackupSuccess tests that the schema changer can handle being backed up any time during a successful schema change.

BackupSuccessMixedVersion is like BackupSuccess but in a mixed-version cluster which is upgraded prior to restoring the backups.

DecomposeToElements exercises the descriptor-to-element decomposition functionality in the form of a data-driven test.

EndToEndSideEffects is a data-driven test runner that executes DDL statements in the declarative schema changer injected with test dependencies and compares the accumulated side effects logs with expected results from the data-driven test file.

ExecuteWithDMLInjection tests that the schema changer behaviour is sane once we start injecting DML statements into execution.

GenerateSchemaChangeCorpus executes each post commit stage of a given set of statements and writes them into a corpus file.

MakePlanExplainer is a PlanExplainer constructor.

Pause tests that the schema changer can handle being paused and resumed correctly.

Rollback tests that the schema changer job rolls back properly.

OldVersionKey is the version key used by the WithMixedVersion method in the TestServerFactory interface.

PlanExplainer makes it easy to store a declarative schema changer plan EXPLAIN (DDL) diagram in a BeforeStage testing knob and load it later on to decorate failing test assertions.

SingleNodeTestClusterFactory is the vanilla implementation of the TestServerFactory interface.

TestServerFactory constructs test clusters for declarative schema changer end-to-end tests.
