	// this jig.
	Class string

	// The interval used to poll urls
	PollInterval time.Duration
}

TestJig holds the relevant state and parameters of the ingress test.

func NewIngressTestJig 

func NewIngressTestJig(c clientset.Interface) *TestJig

NewIngressTestJig instantiates struct with client

func (*TestJig) AddHTTPS 

func (j *TestJig) AddHTTPS(secretName string, hosts ...string)

AddHTTPS updates the ingress to add this secret for these hosts.

func (*TestJig) ConstructFirewallForIngress 

func (j *TestJig) ConstructFirewallForIngress(firewallRuleName string, nodeTags []string) *compute.Firewall

ConstructFirewallForIngress returns the expected GCE firewall rule for the ingress resource

func (*TestJig) CreateIngress 

func (j *TestJig) CreateIngress(manifestPath, ns string, ingAnnotations map[string]string, svcAnnotations map[string]string)

CreateIngress creates the Ingress and associated service/rc. Required: ing.yaml, rc.yaml, svc.yaml must exist in manifestPath Optional: secret.yaml, ingAnnotations If ingAnnotations is specified it will overwrite any annotations in ing.yaml If svcAnnotations is specified it will overwrite any annotations in svc.yaml

func (*TestJig) DeleteTestResource 

func (j *TestJig) DeleteTestResource(cs clientset.Interface, deploy *apps.Deployment, svc *v1.Service, ing *extensions.Ingress) []error

DeleteTestResource deletes given deployment, service and ingress.

func (*TestJig) GetDistinctResponseFromIngress 

func (j *TestJig) GetDistinctResponseFromIngress() (sets.String, error)

GetDistinctResponseFromIngress tries GET call to the ingress VIP and return all distinct responses.

func (*TestJig) GetIngressNodePorts 

func (j *TestJig) GetIngressNodePorts(includeDefaultBackend bool) []string

GetIngressNodePorts returns related backend services' nodePorts. Current GCE ingress controller allows traffic to the default HTTP backend by default, so retrieve its nodePort if includeDefaultBackend is true.

func (*TestJig) GetRootCA 

func (j *TestJig) GetRootCA(secretName string) (rootCA []byte)

GetRootCA returns a rootCA from the ingress test jig.

func (*TestJig) GetServicePorts 

func (j *TestJig) GetServicePorts(includeDefaultBackend bool) map[string]v1.ServicePort

GetServicePorts returns related backend services' svcPorts. Current GCE ingress controller allows traffic to the default HTTP backend by default, so retrieve its nodePort if includeDefaultBackend is true.

func (*TestJig) PrepareTLSSecret 

func (j *TestJig) PrepareTLSSecret(namespace, secretName string, hosts ...string) error

PrepareTLSSecret creates a TLS secret and caches the cert.

VerifyURL polls for the given iterations, in intervals, and fails if the given url returns a non-healthy http code even once.

func (*TestJig) WaitForGivenIngressWithTimeout 

func (j *TestJig) WaitForGivenIngressWithTimeout(ing *extensions.Ingress, waitForNodePort bool, timeout time.Duration) error

WaitForGivenIngressWithTimeout waits till the ingress acquires an IP, then waits for its hosts/urls to respond to a protocol check (either http or https). If waitForNodePort is true, the NodePort of the Service is verified before verifying the Ingress. NodePort is currently a requirement for cloudprovider Ingress.

func (*TestJig) WaitForIngress 

func (j *TestJig) WaitForIngress(waitForNodePort bool)

WaitForIngress waits for the Ingress to get an address. WaitForIngress returns when it gets the first 200 response

func (*TestJig) WaitForIngressAddress 

func (j *TestJig) WaitForIngressAddress(c clientset.Interface, ns, ingName string, timeout time.Duration) (string, error)

WaitForIngressAddress waits for the Ingress to acquire an address.

func (*TestJig) WaitForIngressToStable 

func (j *TestJig) WaitForIngressToStable()

WaitForIngressToStable waits for the LB return 100 consecutive 200 responses.

func (*TestJig) WaitForIngressWithCert 

func (j *TestJig) WaitForIngressWithCert(waitForNodePort bool, knownHosts []string, cert []byte) error

WaitForIngressWithCert waits till the ingress acquires an IP, then waits for its hosts/urls to respond to a protocol check (either http or https). If waitForNodePort is true, the NodePort of the Service is verified before verifying the Ingress. NodePort is currently a requirement for cloudprovider Ingress. Hostnames and certificate need to be explicitly passed in.

type TestLogger
