Types

type Release

type Release struct {
	// contains filtered or unexported fields
}

Release is an implementation of tnf.Test used to determine whether a container is based on Red Hat technologies.

func NewRelease

func NewRelease(timeout time.Duration) *Release

NewRelease create a new Release tnf.Test.

func (*Release) Args

func (r *Release) Args() []string

Args returns the command line arguments for the test.

func (*Release) GetIdentifier

func (r *Release) GetIdentifier() identifier.Identifier

GetIdentifier returns the tnf.Test specific identifier.

func (*Release) ReelEOF

func (r *Release) ReelEOF()

ReelEOF does nothing; no intervention is needed for EOF.

func (*Release) ReelFirst

func (r *Release) ReelFirst() *reel.Step

ReelFirst returns a reel.Step which expects output from running the Args command.

func (*Release) ReelMatch

func (r *Release) ReelMatch(pattern, _, _ string) *reel.Step

ReelMatch determines whether the container is based on Red Hat technologies through pattern matching logic.

func (*Release) ReelTimeout

func (r *Release) ReelTimeout() *reel.Step

ReelTimeout does nothing; no intervention is needed for a timeout.

func (*Release) Result

func (r *Release) Result() int

Result returns the test result.

func (*Release) Timeout

func (r *Release) Timeout() time.Duration

Timeout returns the timeout for the test.
