type ResponseType 

type ResponseType uint

ResponseType is used in the request to specify how the response body should be treated The conversion and validation methods are auto-generated with https://github.com/alvaroloes/enumer: nolint: lll 

const (
	// ResponseTypeText causes k6 to return the response body as a string. It works
	// well for web pages and JSON documents, but it can cause issues with
	// binary files since their data could be lost when they're converted in the
	// UTF-16 strings JavaScript uses.
	// This is the default value for backwards-compatibility, unless the global
	// discardResponseBodies option is enabled.
	ResponseTypeText ResponseType = iota
	// ResponseTypeBinary causes k6 to return the response body as a []byte, suitable
	// for working with binary files without lost data and needless string conversions.
	ResponseTypeBinary
	// ResponseTypeNone causes k6 to fully read the response body while immediately
	// discarding the actual data - k6 would set the body of the returned HTTPResponse
	// to null. This saves CPU and memory and is suitable for HTTP requests that we just
	// want to  measure, but we don't care about their responses' contents. This is the
	// default value for all requests if the global discardResponseBodies is enablled.
	ResponseTypeNone
)

func ResponseTypeString 

func ResponseTypeString(s string) (ResponseType, error)

ResponseTypeString retrieves an enum value from the enum constants string name. Throws an error if the param is not part of the enum.

type Tracer 

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

A Tracer wraps "net/http/httptrace" to collect granular timings for HTTP requests. Note that since there is not yet an event for the end of a request (there's a PR to add it), you must call Done() at the end of the request to get the full timings. It's NOT safe to reuse Tracers between requests. Cheers, love, the cavalry's here.

func (*Tracer) ConnectDone 

func (t *Tracer) ConnectDone(network, addr string, err error)

ConnectDone is called when a new connection's Dial completes. The provided err indicates whether the connection completedly successfully. If net.Dialer.DualStack ("Happy Eyeballs") support is enabled, this may be called multiple times.

If the connection is reused, this won't be called. Otherwise, it will be called after ConnectStart() and before either TLSHandshakeStart() (for TLS connections) or GotConn().

func (*Tracer) ConnectStart 

func (t *Tracer) ConnectStart(network, addr string)

ConnectStart is called when a new connection's Dial begins. If net.Dialer.DualStack (IPv6 "Happy Eyeballs") support is enabled, this may be called multiple times.

If the connection is reused, this won't be called. Otherwise, it will be called after GetConn() and before ConnectDone().

func (*Tracer) Done 

func (t *Tracer) Done() *Trail

Done calculates all metrics and should be called when the request is finished.

func (*Tracer) GetConn 

func (t *Tracer) GetConn(hostPort string)

GetConn is called before a connection is created or retrieved from an idle pool. The hostPort is the "host:port" of the target or proxy. GetConn is called even if there's already an idle cached connection available.

Keep in mind that GetConn won't be called if a connection is reused though, for example when there's a redirect. If it's called, it will be called before all other hooks.

func (*Tracer) GotConn 

func (t *Tracer) GotConn(info httptrace.GotConnInfo)

GotConn is called after a successful connection is obtained. There is no hook for failure to obtain a connection; instead, use the error from Transport.RoundTrip.

This is the fist hook called for reused connections. For new connections, it's called either after TLSHandshakeDone() (for TLS connections) or after ConnectDone()

func (*Tracer) GotFirstResponseByte 

func (t *Tracer) GotFirstResponseByte()

GotFirstResponseByte is called when the first byte of the response headers is available. If the request was cancelled, this could be called after the RoundTrip() method has returned.

func (*Tracer) TLSHandshakeDone 

func (t *Tracer) TLSHandshakeDone(state tls.ConnectionState, err error)

TLSHandshakeDone is called after the TLS handshake with either the successful handshake's connection state, or a non-nil error on handshake failure.

If the connection is reused, this won't be called. Otherwise, it will be called after TLSHandshakeStart() and before GotConn(). If the request was cancelled, this could be called after the RoundTrip() method has returned.

func (*Tracer) TLSHandshakeStart 

func (t *Tracer) TLSHandshakeStart()

TLSHandshakeStart is called when the TLS handshake is started. When connecting to a HTTPS site via a HTTP proxy, the handshake happens after the CONNECT request is processed by the proxy.

If the connection is reused, this won't be called. Otherwise, it will be called after ConnectDone() and before TLSHandshakeDone().

func (*Tracer) Trace 

func (t *Tracer) Trace() *httptrace.ClientTrace

Trace returns a premade ClientTrace that calls all of the Tracer's hooks.

func (*Tracer) WroteRequest 

func (t *Tracer) WroteRequest(info httptrace.WroteRequestInfo)

WroteRequest is called with the result of writing the request and any body. It may be called multiple times in the case of retried requests.

type Trail 

type Trail struct {
	StartTime time.Time
	EndTime   time.Time

	// Total connect time (Connecting + TLSHandshaking)
	ConnDuration time.Duration

	// Total request duration, excluding DNS lookup and connect time.
	Duration time.Duration

	Blocked        time.Duration // Waiting to acquire a connection.
	Connecting     time.Duration // Connecting to remote host.
	TLSHandshaking time.Duration // Executing TLS handshake.
	Sending        time.Duration // Writing request.
	Waiting        time.Duration // Waiting for first byte.
	Receiving      time.Duration // Receiving response.

	// Detailed connection information.
	ConnReused     bool
	ConnRemoteAddr net.Addr
	Errors         []error

	// Populated by SaveSamples()
	Tags    *stats.SampleTags
	Samples []stats.Sample
}

A Trail represents detailed information about an HTTP request. You'd typically get one from a Tracer.

func (*Trail) GetSamples 

func (tr *Trail) GetSamples() []stats.Sample

GetSamples implements the stats.SampleContainer interface.

func (*Trail) GetTags 

func (tr *Trail) GetTags() *stats.SampleTags

GetTags implements the stats.ConnectedSampleContainer interface.

func (*Trail) GetTime 

func (tr *Trail) GetTime() time.Time

GetTime implements the stats.ConnectedSampleContainer interface.

func (*Trail) SaveSamples 

func (tr *Trail) SaveSamples(tags *stats.SampleTags)

SaveSamples populates the Trail's sample slice so they're accesible via GetSamples()

type URL 

type URL struct {
	Name string // http://example.com/thing/${}/
	URL  string // http://example.com/thing/1234/
	// contains filtered or unexported fields
}

A URL wraps net.URL, and preserves the template (if any) the URL was constructed from.

func NewURL 

func NewURL(urlString, name string) (URL, error)

NewURL returns a new URL for the provided url and name. The error is returned if the url provided can't be parsed

func (URL) GetURL 

func (u URL) GetURL() *url.URL

GetURL returns the internal url.URL
