README

Assertion

If you intend to introduce a new assertion, please follow this approach:

• We want to avoid writing generic assertions, that are specific to certain tests. Assertions should contain no custom logic, and instead support dependency injection.
• If you are unsure if an assertion is generic, start by adding it directly to your test, and then you can make it more generic in a follow-up.

Conventions

Contextual Assertions

Some assertions provided in this package may consider the Gloo Gateway context for conditional logic based on metadata about the installation being asserted against. One example is asserting behavior differently if the validating webhook is installed and configured to reject certain resources.

Well Known Manifests

Additionally, some assertions may rely on well-known strings in the manifest filenames for conditional logic. As mentioned above, an example is asserting behavior differently if a manifest is expected to be rejected by the validating webhook.

Constants

const WebhookReject = "webhook-reject"

WebhookReject is a well-known string that should be placed in the filename of any manifest which should be rejected by the Gloo Gateway validating webhook if it is enabled and configured to reject on errors. This acts as signal for any assertion which needs to know if the manifest is expected to not be admitted to the cluster.

Types

type Provider

type Provider struct {
	Assert  *assert.Assertions
	Require *require.Assertions

	// Gomega is well-used around the codebase, so we also add support here
	// NOTE TO DEVELOPERS: We recommend relying on testify assertions where possible
	Gomega gomega.Gomega
	// contains filtered or unexported fields
}

Provider is the entity that provides methods which assert behaviors of a Kubernetes Cluster These assertions occur against a running instance of Gloo Gateway, within a Kubernetes Cluster.

func NewProvider

func NewProvider(t *testing.T) *Provider

NewProvider returns a Provider that will provide Assertions that can be executed against an installation of Gloo Gateway

func (*Provider) AssertEnvoyAdminApi

func (p *Provider) AssertEnvoyAdminApi(
	ctx context.Context,
	envoyDeployment metav1.ObjectMeta,
	adminAssertions ...func(ctx context.Context, adminClient *admincli.Client),
)

func (*Provider) AssertEventualCurlResponse

func (p *Provider) AssertEventualCurlResponse(
	ctx context.Context,
	podOpts kubectl.PodExecOptions,
	curlOptions []curl.Option,
	expectedResponse *matchers.HttpResponse,
	timeout ...time.Duration,
)

func (*Provider) AssertEventuallyConsistentCurlResponse

func (p *Provider) AssertEventuallyConsistentCurlResponse(
	ctx context.Context,
	podOpts kubectl.PodExecOptions,
	curlOptions []curl.Option,
	expectedResponse *matchers.HttpResponse,
	timeout ...time.Duration,
)

AssertEventuallyConsistentCurlResponse asserts that the response from a curl command eventually and then consistently matches the expected response

func (*Provider) AssertHTTPRouteStatusContainsSubstring

func (p *Provider) AssertHTTPRouteStatusContainsSubstring(route *gwv1.HTTPRoute, message string)

AssertHTTPRouteStatusContainsSubstring asserts that at least one of the HTTPRoute's route parent statuses contains the given message substring.

func (*Provider) EventuallyCheckResourcesOk

func (p *Provider) EventuallyCheckResourcesOk(ctx context.Context)

EventuallyCheckResourcesOk asserts that `glooctl check` eventually responds Ok

func (*Provider) EventuallyInstallationSucceeded

func (p *Provider) EventuallyInstallationSucceeded(ctx context.Context)

func (*Provider) EventuallyObjectsExist

func (p *Provider) EventuallyObjectsExist(ctx context.Context, objects ...client.Object)

func (*Provider) EventuallyObjectsNotExist

func (p *Provider) EventuallyObjectsNotExist(ctx context.Context, objects ...client.Object)

func (*Provider) EventuallyPodsMatches

func (p *Provider) EventuallyPodsMatches(
	ctx context.Context,
	podNamespace string,
	listOpt metav1.ListOptions,
	matcher types.GomegaMatcher,
	timeout ...time.Duration,
)

EventuallyPodsMatches asserts that the pod(s) in the given namespace matches the provided matcher

func (*Provider) EventuallyPodsRunning

func (p *Provider) EventuallyPodsRunning(
	ctx context.Context,
	podNamespace string,
	listOpt metav1.ListOptions,
