Expectation represents the expected result of some operation.
type Expectation struct {
// contains filtered or unexported fields
}
func ExpectSuccess() *Expectation
ExpectSuccess returns an Expectation that trivially expects success.
func ParseExpectation(data []byte) (*Expectation, error)
ParseExpectation parses the serialized form of an Expectation.
func ParseFile(testPath string) (io.Reader, version.Version, *Expectation, error)
ParseFile parses a test file generated by the testgen package.
func (e *Expectation) Check(err error) error
Check validates whether err conforms to the expectation. Returns an error if it does not conform.
Conformance means that if failure is true, then err must be non-nil. If err is non-nil, then it must match errorMatcher.
Validator is a type used for validating a stream of trace.Events.
type Validator struct {
GoVersion version.Version
// contains filtered or unexported fields
}
func NewValidator() *Validator
NewValidator creates a new Validator.
func (v *Validator) Event(ev trace.Event) error
Event validates ev as the next event in a stream of trace.Events.
Returns an error if validation fails.
func (v *Validator) SkipClockSnapshotChecks()
SkipClockSnapshotChecks causes the validator to skip checks on the clock snapshots.
Some platforms like Windows, with a small enough trace period, are unable to produce monotonically increasing timestamps due to very coarse clock granularity.
