func AssertErrPreparedWithCtx(t *testing.T, e QueryEngine, harness Harness, ctx *sql.Context, query string, expectedErrKind *errors.Kind, errStrs ...string)

AssertErrPreparedWithCtx is the same as AssertErr, but uses the context given instead of creating one from a harness

func AssertErrWithBindings added in v0.10.0

func AssertErrWithBindings(t *testing.T, e QueryEngine, harness Harness, query string, bindings map[string]*querypb.BindVariable, expectedErrKind *errors.Kind, errStrs ...string)

AssertErrWithBindings asserts that the given query returns an error during its execution, optionally specifying a type of error.

func AssertErrWithCtx added in v0.10.0

func AssertErrWithCtx(t *testing.T, e QueryEngine, harness Harness, ctx *sql.Context, query string, expectedErrKind *errors.Kind, errStrs ...string)

func AssertWarningAndTestQuery added in v0.10.0

func AssertWarningAndTestQuery(
	t *testing.T,
	e QueryEngine,
	ctx *sql.Context,
	harness Harness,
	query string,
	expected []sql.Row,
	expectedCols []*sql.Column,
	expectedCode int,
	expectedWarningsCount int,
	expectedWarningMessageSubstring string,
	skipResultsCheck bool,
)

AssertWarningAndTestQuery tests the query and asserts an expected warning code. If |ctx| is provided, it will be used. Otherwise the harness will be used to create a fresh context.

func CheckIndexedAccess added in v0.18.0

func CreateNewConnectionForServerEngine added in v0.18.0

func CreateNewConnectionForServerEngine(ctx *sql.Context, e QueryEngine) error

func WidenRow(sch sql.Schema, row sql.Row) sql.Row

WidenRow returns a row with all values widened to their widest type

func WidenRows

func WidenRows(sch sql.Schema, rows []sql.Row) []sql.Row

WidenRows returns a slice of rows with all values widened to their widest type. For a variety of reasons, the widths of various primitive types can vary when passed through different SQL queries (and different database implementations). We may eventually decide that this undefined behavior is a problem, but for now it's mostly just an issue when comparing results in tests. To get around this, we widen every type to its widest value in actual and expected results.

Types

type ClientHarness added in v0.12.0

type ClientHarness interface {
	Harness

	// NewContextWithClient returns a context that will return the given client when requested from the session.
	NewContextWithClient(client sql.Client) *sql.Context
}

type ForeignKeyHarness

	// SupportsForeignKeys returns whether this harness should accept CREATE FOREIGN KEY statements as part of test
	// setup.
	SupportsForeignKeys() bool
}

ForeignKeyHarness is an extension to Harness that lets an integrator test their implementation with foreign keys. Integrator tables must implement sql.ForeignKeyTable.

type Harness

type Harness interface {
	// Parallelism returns how many parallel go routines to use when constructing an engine for test.
	Parallelism() int
	// NewContext allows a harness to specify any sessions or context variables necessary for the proper functioning of
	// their engine implementation. Every harnessed engine test uses the context created by this method, with some
	// additional information (e.g. current DB) set uniformly. To replicate the behavior of tests during setup,
	// harnesses should generally dispatch to enginetest.NewContext(harness), rather than calling this method themselves.
	NewContext() *sql.Context
	// Setup supplies a test suite's setup scripts, which must be stored and used to create a new Engine on demand via
	// calls to the NewEngine method.
	Setup(...[]setup.SetupScript)
	// NewEngine creates a new sqle.Engine. The state of the engine returned must match what was previous specified
	// by Setup, with no other data. See enginetest.NewEngine for help creating an engine suitable in tests.
	NewEngine(*testing.T) (QueryEngine, error)
}

Harness provides a way for database integrators to validate their implementation against the standard set of queries used to develop and test the engine itself. See memory_engine_test.go for an example. The typical harness lifecycle during test setup looks like this: 1) Harness is instantiated, which should create a sql.MutableDatabaseProvider to use for the rest of setup 2) Harness.NewDatabase or Harness.NewTable is called to create the database and tables that will be used for the test 3) For some tests, harness.Setup() is called instead of Harness.NewDatabase and Harness.NewTable 4) Harness.NewEngine() is called to create an engine with the setup data provided prior. It can be called multiple times during a single test run, and must return a "fresh" engine instance each time, i.e. an instance that contains exactly the test data provided via other setup methods.

	Harness

	// InitializeIndexDriver initializes the index driver for this test run with the databases given
