Variables

var DefaultHttpClient = &http.Client{
	Timeout: time.Second * 2,
}

DefaultHttpClient should be used in tests because it configures a timeout which the http.DefaultClient does not have

Please note that when the server response time exceeds the client timeout, you may hit the following error: 

"Client.Timeout exceeded while awaiting headers"

The solution would be to increase the client timeout defined below. We chose 2 seconds as a reasonable default which allows tests to pass consistently. Since http.Client caches TCP connections, it is advised to create a new client via DefaultClientBuilder().Build() each time while testing any feature that operates at L4 to avoid TCP connection caching issues.

Functions

func BuildHelmValues added in v1.17.2 

func BuildHelmValues(values HelmValues) (map[string]interface{}, error)

BuildHelmValues reads the base values.yaml file from a Helm chart and merges it with the provided values each entry in valuesArgs should look like `path.to.helm.field=value`

func GitRootDirectory added in v1.17.0 

func GitRootDirectory() string

GitRootDirectory returns the path of the top-level directory of the working tree.

func IsEnvDefined added in v1.15.0 

func IsEnvDefined(envVarName string) bool

IsEnvDefined returns true if a given environment variable has any value Deprecated: Prefer envutils.IsEnvDefined

func IsEnvTruthy 

func IsEnvTruthy(envVarName string) bool

IsEnvTruthy returns true if a given environment variable has a truthy value Examples of truthy values are: "1", "t", "T", "true", "TRUE", "True". Anything else is considered false. Deprecated: Prefer envutils.IsEnvTruthy

func IsRunningInCloudbuild added in v1.15.0 

func IsRunningInCloudbuild() bool

IsRunningInCloudbuild returns true if tests are running in Cloudbuild

func ShouldSkipInstall 

func ShouldSkipInstall() bool

ShouldSkipInstall returns true if any assets that need to be created before a test (for example Gloo being installed) should be skipped. This is typically used in tandem with ShouldTearDown when running consecutive tests and skipping both the tear down and install of Gloo Edge.

func ShouldSkipIstioInstall added in v1.17.0 

func ShouldSkipIstioInstall() bool

ShouldSkipIstioInstall returns true if any assets that need to be created before a test (for example Gloo being installed) should be skipped. This is typically used in tandem with ShouldTearDown when running consecutive tests and skipping both the tear down and install of Gloo Edge.

func ShouldSkipTempDisabledTests 

func ShouldSkipTempDisabledTests() bool

ShouldSkipTempDisabledTests returns true if temporarily disabled tests should be skipped

func ShouldTearDown 

func ShouldTearDown() bool

ShouldTearDown returns true if any assets that were created before a test (for example Gloo being installed) should be torn down after the test.

func ValidateHelmValues added in v1.17.2 

func ValidateHelmValues(unstructuredHelmValues map[string]interface{}) error

ValidateHelmValues ensures that the unstructured helm values that are provided to a chart match the Go type used to generate the Helm documentation Returns nil if all the provided values are all included in the Go struct Returns an error if a provided value is not included in the Go struct.

Example: 

Failed to render manifest
    Unexpected error:
        <*errors.errorString | 0xc000fedf40>: {
            s: "error unmarshaling JSON: while decoding JSON: json: unknown field \"useTlsTagging\"",
        }
        error unmarshaling JSON: while decoding JSON: json: unknown field "useTlsTagging"
    occurred

This means that the unstructured values provided to the Helm chart contain a field `useTlsTagging` but the Go struct does not contain that field.

func ValidateRequirements 

func ValidateRequirements(requirements []Requirement) error

ValidateRequirements returns an error if any of the Requirements are not met

func ValidateRequirementsAndNotifyGinkgo 

func ValidateRequirementsAndNotifyGinkgo(requirements ...Requirement)

ValidateRequirementsAndNotifyGinkgo validates that the provided Requirements are met, and if they are not, uses the InvalidTestReqsEnvVar to determine how to proceed: Options are:

  • `run`: Ignore any invalid requirements and execute the tests
  • `skip`: Notify Ginkgo that the current spec was skipped
  • `fail`: Notify Ginkgo that the current spec has failed [DEFAULT]
