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.

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) AssertCurlResponse 

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

func (*Provider) AssertCurlReturnResponse 

func (p *Provider) AssertCurlReturnResponse(
	ctx context.Context,
	podOpts kubectl.PodExecOptions,
	curlOptions []curl.Option,
	expectedResponse *matchers.HttpResponse,
) *http.Response

func (*Provider) AssertEnvoyAdminApi 

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

func (*Provider) AssertEventualCurlError added in v1.17.5 

func (p *Provider) AssertEventualCurlError(
	ctx context.Context,
	podOpts kubectl.PodExecOptions,
	curlOptions []curl.Option,
	expectedErrorCode int,
	timeout ...time.Duration,
)

AssertEventualCurlError asserts that the response from a curl command is an error such as `Failed to connect` as opposed to an http error from the server. This is useful when testing that a service is not reachable, for example to validate that a delete operation has taken effect.

func (*Provider) AssertEventualCurlResponse 

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

We can't use one function and ignore the response because the response body must be closed

func (*Provider) AssertEventualCurlReturnResponse 

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

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) AssertGlooAdminApi added in v1.17.4 

func (p *Provider) AssertGlooAdminApi(
	ctx context.Context,
	glooDeployment metav1.ObjectMeta,
