func RunConformanceTests Uses

func RunConformanceTests(t *testing.T, newHarness HarnessMaker, asTests []AsTest)

RunConformanceTests runs conformance tests for driver implementations of runtimevar.

type AsTest Uses

type AsTest interface {
    // Name should return a descriptive name for the test.
    Name() string
    // SnapshotCheck will be called to allow verification of Snapshot.As.
    SnapshotCheck(s *runtimevar.Snapshot) error
    // ErrorCheck will be called to allow verification of Variable.ErrorAs.
    // driver is provided so that errors other than err can be checked;
    // Variable.ErrorAs won't work since it expects driver errors to be wrapped.
    ErrorCheck(v *runtimevar.Variable, err error) error
}

AsTest represents a test of As functionality. The conformance test: 1. Reads a Snapshot of the variable before it exists. 2. Calls ErrorCheck. 3. Creates the variable and reads a Snapshot of it. 4. Calls SnapshotCheck.

type Harness Uses

type Harness interface {
    // MakeWatcher creates a driver.Watcher to watch the given variable.
    MakeWatcher(ctx context.Context, name string, decoder *runtimevar.Decoder) (driver.Watcher, error)
    // CreateVariable creates the variable with the given contents.
    CreateVariable(ctx context.Context, name string, val []byte) error
    // UpdateVariable updates an existing variable to have the given contents.
    UpdateVariable(ctx context.Context, name string, val []byte) error
    // DeleteVariable deletes an existing variable.
    DeleteVariable(ctx context.Context, name string) error
    // Close is called when the test is complete.
    Close()
    // Mutable returns true iff the driver supports UpdateVariable/DeleteVariable.
    // If false, those functions should return errors, and the conformance tests
    // will skip and/or ignore errors for tests that require them.
    Mutable() bool
}

Harness descibes the functionality test harnesses must provide to run conformance tests.

type HarnessMaker Uses

type HarnessMaker func(t *testing.T) (Harness, error)

HarnessMaker describes functions that construct a harness for running tests. It is called exactly once per test; Harness.Close() will be called when the test is complete.

type Message Uses

type Message struct {
    Name, Text string
}

Message is used as a target for JSON decoding.
