Constants

View Source 
const BackupStorageImplementation = "grpcvtctldserver.testutil"

BackupStorageImplementation is the name this package registers its test backupstorage.BackupStorage implementation as. Users should set *backupstorage.BackupStorageImplementation to this value before use.

Variables

View Source 
var BackupStorage = &backupStorage{
	Backups: map[string][]string{},
}

BackupStorage is the singleton test backupstorage.BackupStorage intastnce. It is public and singleton to allow tests to both mutate and assert against its state.

Functions

func AddKeyspace 

func AddKeyspace(ctx context.Context, t *testing.T, ts *topo.Server, ks *vtctldatapb.Keyspace)

AddKeyspace adds a keyspace to a topology, failing a test if that keyspace could not be added. It shallow copies the proto struct to prevent XXX_ fields from changing in the marshalling.

func AddKeyspaces 

func AddKeyspaces(ctx context.Context, t *testing.T, ts *topo.Server, keyspaces ...*vtctldatapb.Keyspace)

AddKeyspaces adds a list of keyspaces to the topology, failing a test if any of those keyspaces cannot be added. See AddKeyspace for details.

func AddShards 

func AddShards(ctx context.Context, t *testing.T, ts *topo.Server, shards ...*vtctldatapb.Shard)

AddShards adds a list of shards to the topology, failing a test if any of the shard records could not be created. It also ensures that every shard's keyspace exists, or creates an empty keyspace if that shard's keyspace does not exist.

func AddSrvKeyspaces 

func AddSrvKeyspaces(t *testing.T, ts *topo.Server, srvKeyspaces ...*SrvKeyspace)

AddSrvKeyspaces adds one or more SrvKeyspace objects to the topology. It fails the calling test if any of the objects fail to update.

func AddTablet 

func AddTablet(ctx context.Context, t *testing.T, ts *topo.Server, tablet *topodatapb.Tablet, opts *AddTabletOptions)

AddTablet adds a tablet to the topology, failing a test if that tablet record could not be created. It shallow copies to prevent XXX_ fields from changing, including nested proto message fields.

AddTablet also optionally adds empty keyspace and shard records to the topology, if they are set on the tablet record and they cannot be retrieved from the topo server without error.

If AddTablet receives a tablet record with a keyspace and shard set, and that tablet's type is PRIMARY, and opts.AlsoSetShardPrimary is set, then AddTablet will update the shard record to make that tablet the shard primary and set the shard to serving. If that shard record already has a serving primary, then AddTablet will fail the test.

func AddTablets 

func AddTablets(ctx context.Context, t *testing.T, ts *topo.Server, opts *AddTabletOptions, tablets ...*topodatapb.Tablet)

AddTablets adds a list of tablets to the topology. See AddTablet for more details.

func AssertEmergencyReparentShardResponsesEqual 

func AssertEmergencyReparentShardResponsesEqual(t *testing.T, expected *vtctldatapb.EmergencyReparentShardResponse, actual *vtctldatapb.EmergencyReparentShardResponse, msgAndArgs ...any)

AssertEmergencyReparentShardResponsesEqual asserts that two vtctldatapb.EmergencyReparentShardResponse objects are equal, ignoring their respective Events field in the comparison.

func AssertKeyspacesEqual 

func AssertKeyspacesEqual(t *testing.T, expected *vtctldatapb.Keyspace, actual *vtctldatapb.Keyspace, msgAndArgs ...any)

AssertKeyspacesEqual is a convenience function to assert that two vtctldatapb.Keyspace objects are equal, after clearing out any reserved proto XXX_ fields.

func AssertLogutilEventsMatch added in v0.13.0 

func AssertLogutilEventsMatch(t testing.TB, expected []*logutilpb.Event, actual []*logutilpb.Event)

AssertLogutilEventsMatch asserts that two slices of Events match, by their .Value fields. In the expected slice, .Value is treated as a regular expression; that is, it is passed as a regexp-like string to assert.Regexp.

NOTE: To match events independent of ordering, callers should run both their expected and actual event slices through the EventValueSorter before calling this function. This will mutate the slices, so make a copy first if that is an issue for your use case.

func AssertLogutilEventsOccurred 

func AssertLogutilEventsOccurred(t *testing.T, container interface{ GetEvents() []*logutilpb.Event }, msgAndArgs ...any)

AssertLogutilEventsOccurred asserts that for something containing a slice of logutilpb.Event, that the container is non-nil, and the event slice is non-zero.

This test function is generalized with an anonymous interface that any protobuf type containing a slice of logutilpb.Event elements called Events, which is the convention in protobuf types in the Vitess codebase, already implements.

func AssertNoLogutilEventsOccurred 

func AssertNoLogutilEventsOccurred(t *testing.T, container interface{ GetEvents() []*logutilpb.Event }, msgAndArgs ...any)

AssertNoLogutilEventsOccurred asserts that for something containing a slice of logutilpb.Event, that the container is either nil, or that the event slice is exactly zero length.

This test function is generalized with an anonymous interface that any protobuf type containing a slice of logutilpb.Event elements called Events, which is the convention in protobuf types in the Vitess codebase, already implements.

func AssertPlannedReparentShardResponsesEqual 

func AssertPlannedReparentShardResponsesEqual(t *testing.T, expected *vtctldatapb.PlannedReparentShardResponse, actual *vtctldatapb.PlannedReparentShardResponse)

AssertPlannedReparentShardResponsesEqual asserts that two vtctldatapb.PlannedReparentShardResponse objects are equal, ignoring their respective Events field in the comparison.

func AssertSameTablets added in v0.11.0 

func AssertSameTablets(t *testing.T, expected, actual []*topodatapb.Tablet)

func MockGetVersionFromTablet added in v0.14.0 

func MockGetVersionFromTablet(addrVersionMap map[string]string) func(ta string) (string, error)

func NewVtctldServerWithTabletManagerClient 

func NewVtctldServerWithTabletManagerClient(t testing.TB, ts *topo.Server, tmc tmclient.TabletManagerClient, newVtctldServerFn func(ts *topo.Server) vtctlservicepb.VtctldServer) vtctlservicepb.VtctldServer

NewVtctldServerWithTabletManagerClient returns a new grpcvtctldserver.VtctldServer configured with the given topo server and tmclient.TabletManagerClient implementation for testing.

It synchronizes on private locks to prevent multiple goroutines from stepping on each other during VtctldServer initialization, but still run the rest of the test in parallel.

NOTE, THE FIRST: It is only safe to use in parallel with other tests using this method of creating a VtctldServer, or with tests that do not depend on a VtctldServer's tmclient.TabletManagerClient implementation.

NOTE, THE SECOND: It needs to register a unique name to the tmclient factory registry, so we keep a shadow map of factories registered for "protocols" by this function. That way, if we happen to have multiple tests with the same name, we can swap out the return value for the factory and allow both tests to run, rather than the second test failing when it attempts to register a second factory for the same "protocol" name.

NOTE, THE THIRD: we take a "new" func to produce a valid vtctlservicepb.VtctldServer implementation, rather than constructing directly ourselves with grpcvtctldserver.NewVtctldServer. This is to prevent an import cycle between this package and package grpcvtctldserver. Further, because the return type of NewVtctldServer is the struct type (*grpcvtctldserver.VtctldServer) and not the interface type vtctlservicepb.VtctldServer, tests will need to indirect that call through an extra layer rather than passing the function identifier directly, e.g.: 

vtctld := testutil.NewVtctldServerWithTabletManagerClient(t, ts, &testutil.TabletManagerClient{
	...
}, func(ts *topo.Server) vtctlservicepb.VtctldServer { return NewVtctldServer(ts) })

func SetupReplicationGraphs 

func SetupReplicationGraphs(ctx context.Context, t *testing.T, ts *topo.Server, replicationGraphs ...*topo.ShardReplicationInfo)

SetupReplicationGraphs creates a set of ShardReplication objects in the topo, failing the test if any of the records could not be created.

func UpdateSrvKeyspaces 

func UpdateSrvKeyspaces(ctx context.Context, t *testing.T, ts *topo.Server, srvkeyspacesByCellByKeyspace map[string]map[string]*topodatapb.SrvKeyspace)

UpdateSrvKeyspaces updates a set of SrvKeyspace records, grouped by cell and then by keyspace. It fails the test if any records cannot be updated.

func WithTestServer 

func WithTestServer(
	t *testing.T,
	server vtctlservicepb.VtctldServer,
	test func(t *testing.T, client vtctldclient.VtctldClient),
)

WithTestServer creates a gRPC server listening locally with the given RPC implementation, then runs the test func with a client created to point at that server.

func WithTestServers 

func WithTestServers(
	t *testing.T,
	test func(t *testing.T, clients ...vtctldclient.VtctldClient),
	servers ...vtctlservicepb.VtctldServer,
)

WithTestServers creates N gRPC servers listening locally with the given RPC implementations, and then runs the test func with N clients created, where clients[i] points at servers[i].

Types

type AddTabletOptions 

type AddTabletOptions struct {
	// AlsoSetShardPrimary is an option to control additional setup to take when
	// AddTablet receives a tablet of type PRIMARY. When set, AddTablet will also
	// update the shard record to make that tablet the primary, and fail the
	// test if the shard record has a serving primary already.
	AlsoSetShardPrimary bool
	// ForceSetShardPrimary, when combined with AlsoSetShardPrimary, will ignore
	// any existing primary in the shard, making the current tablet the serving
	// primary (given it is type PRIMARY), and log that it has done so.
	ForceSetShardPrimary bool
	// SkipShardCreation, when set, makes AddTablet never attempt to create a
	// shard record in the topo under any circumstances.
