Constants

View Source 
const MediaType = `application/vnd.oci.image.layer.nondistributable.v1.tar`

MediaType is a media type that can be used in [claircore.LayerDescription]s in tests.

Variables

View Source 
var AnyDescription = claircore.LayerDescription{
	Digest:    `sha256:` + strings.Repeat(`deadbeef`, 8),
	URI:       `example:test.AnyDescription`,
	MediaType: MediaType,
	Headers:   make(map[string][]string),
}

AnyDescription is pre-made [LayerDescription] for cases where the actual contents of the description *shouldn't* matter.

Functions

func GenDuplicatePackages 

func GenDuplicatePackages(n int) ([]*claircore.Package, error)

GenUniqueRepositories creates an array of unique repositories.

The array is guaranteed not to have any duplicated fields.

func GenUniqueRepositoryScanners

The array is guaranteed not to have any duplicated fields.

func GenerateFixture added in v1.5.20 

func GenerateFixture(t testing.TB, name string, stamp time.Time, gen func(testing.TB, *os.File)) string

GenerateFixture is a helper for generating a test fixture. A path that can be used to open the file is returned.

If the test fails, the cached file is removed. It is the caller's responsibility to ensure that "name" is unique per-package.

func Modtime added in v1.5.20 

func Modtime(t testing.TB, path string) time.Time

Modtime is a helper for picking a timestamp to use with GenerateFixture and [GenerateLayer].

It reports the modtime of the passed path. If the file does not exist, the start of the UNIX epoch is returned. If the file is not regular or a directory, the test is failed. If the file is a directory, the newest time of all the entries is reported.

func RandomSHA256Digest added in v0.0.14 

func RandomSHA256Digest(t testing.TB) claircore.Digest

RandomSHA256Digest returns a random Digest.

func RealizeLayer added in v1.5.20

This is useful for testing a Scanner implementation.

func RealizeLayers added in v0.0.13 

func RealizeLayers(ctx context.Context, t *testing.T, refs ...LayerRef) []claircore.Layer

RealizeLayers uses fetch.Layer to populate a directory and returns a slice of Layers describing them.

Any needed cleanup is handled via the passed testing.T.

func ServeLayers added in v0.0.13 

func ServeLayers(t *testing.T, n int) (*http.Client, []claircore.LayerDescription)

ServeLayers constructs "n" random layers, arranges to serve them, and returns corresponding LayerDescriptions.

func WFN added in v0.0.24 

func WFN(i int) cpe.WFN

WFN returns a cpe.WFN with "i" as the CPE version.

Types

type CachedArena added in v1.5.20 

type CachedArena struct {
	// contains filtered or unexported fields
}

CachedArena is an indexer.FetchArena that populates Layers out of the testing caches.

func NewCachedArena added in v1.5.20

func (*CachedArena) GenerateLayer added in v1.5.20 

func (a *CachedArena) GenerateLayer(t testing.TB, name string, stamp time.Time, gen func(testing.TB, *os.File))

GenerateLayer is used for tests that generate their layer data rather than fetch it from a registry.

If the test fails, the cached file is removed. If successful, the layer can be referenced by using a relative file URI for "name". That is, if the passed name is "layer.tar", a claircore.LayerDescription should use a URI of "file:layer.tar".

It is the caller's responsibility to ensure that "name" is unique per-package.

func (*CachedArena) LoadLayerFromRegistry added in v1.5.20 

func (a *CachedArena) LoadLayerFromRegistry(ctx context.Context, t testing.TB, ref LayerRef)

LoadLayerFromRegistry fetches a layer from a registry into the appropriate cache.

}

LayerRef is a remote layer.

type ScannerTestcase added in v0.0.16 

type ScannerTestcase struct {
	Domain  string
	Name    string
	Hash    string
	Want    []*claircore.Package
	Scanner indexer.PackageScanner
}

ScannerTestcase can be used for testing layers found in the wild against a scanner.

Tests that use this struct should not be marked as integration tests, as the Run method does that internally if it needs to talk to the network.

func (ScannerTestcase) Digest added in v0.0.16 

func (tc ScannerTestcase) Digest() claircore.Digest

Digest reports the digest in the Hash member.

Panics if an error is returned from ParseDigest.

func (tc ScannerTestcase) Run(ctx context.Context) func(*testing.T)

Run returns a function suitable for using with (*testing.T).Run.

This function assumes the returned values must exactly match tc.Want. If tc.Want only covers a subset of potential returned values, then use RunSubset.

func (tc ScannerTestcase) RunSubset(ctx context.Context, n int) func(*testing.T)

RunSubset returns a function suitable for using with (*testing.T).Run.
