func AwaitConvergence(t *testing.T, threshold int, maxTimeToConsistency time.Duration, fn func(elapsed time.Duration) bool)
AwaitConvergence runs the given function until it returns 'true' `threshold` times in a row. Each failed attempt has a 1s delay; successful attempts have no delay.
func CalculateHost(t *testing.T, gwAddr, scheme string) string
CalculateHost will calculate the Host header as per HTTP spec. To summarize, host will not include any port if it is implied from the scheme. In case of any error, the input gwAddr will be returned as the default.
func CompareRequest(t *testing.T, req *roundtripper.Request, cReq *roundtripper.CapturedRequest, cRes *roundtripper.CapturedResponse, expected ExpectedResponse) error
func ExpectMirroredRequest(t *testing.T, client client.Client, clientset clientset.Interface, mirrorPods []BackendRef, path string)
func MakeRequest(t *testing.T, expected *ExpectedResponse, gwAddr, protocol, scheme string) roundtripper.Request
func MakeRequestAndExpectEventuallyConsistentResponse(t *testing.T, r roundtripper.RoundTripper, timeoutConfig config.TimeoutConfig, gwAddr string, expected ExpectedResponse)
MakeRequestAndExpectEventuallyConsistentResponse makes a request with the given parameters, understanding that the request may fail for some amount of time.
Once the request succeeds consistently with the response having the expected status code, make additional assertions on the response body using the provided ExpectedResponse.
func WaitForConsistentResponse(t *testing.T, r roundtripper.RoundTripper, req roundtripper.Request, expected ExpectedResponse, threshold int, maxTimeToConsistency time.Duration)
WaitForConsistentResponse repeats the provided request until it completes with a response having the expected response consistently. The provided threshold determines how many times in a row this must occur to be considered "consistent".

ExpectedRequest defines expected properties of a request that reaches a backend.
type ExpectedRequest struct {
Request
// AbsentHeaders are names of headers that are expected
// *not* to be present on the request.
AbsentHeaders []string
}
ExpectedResponse defines the response expected for a given request.
type ExpectedResponse struct {
// Request defines the request to make.
Request Request
// ExpectedRequest defines the request that
// is expected to arrive at the backend. If
// not specified, the backend request will be
// expected to match Request.

Backend string
Namespace string
// MirroredTo is the destination BackendRefs of the mirrored request.
MirroredTo []BackendRef

}
func (er *ExpectedResponse) GetTestCaseName(i int) string
GetTestCaseName gets the user-defined test case name or generates one from expected response to a given request.
Request can be used as both the request to make and a means to verify that echoserver received the expected request. Note that multiple header values can be provided, as a comma-separated value.
