Functions

func AssertReadDoesNotReturnBefore

func AssertReadDoesNotReturnBefore(t testing.TB, ch <-chan struct{}, timeout time.Duration)

AssertReadDoesNotReturnBefore will call t.Fatalf if the first read from the channel happens before timeout.

func AssertReadReturnsBefore

func AssertReadReturnsBefore(t testing.TB, ch <-chan struct{}, timeout time.Duration)

AssertReadReturnsBefore will call t.Fatalf if the first read from the channel doesn't happen before timeout.

func AssertReadReturnsBetween

func AssertReadReturnsBetween(t testing.TB, ch <-chan struct{}, x, y time.Duration)

AssertReadReturnsBetween will call t.Fatalf if the first read from the channel doesn't happen between x and y.

func CopyFile

func CopyFile(t testing.TB, src, dst string)

CopyFile copies the file.

func ExpandPath

func ExpandPath(file string) string

ExpandPath returns testdata/file.

func LoadChain

func LoadChain(t *testing.T, file string) []*x509.Certificate

LoadChain loads a certificate chain from a file. The file must be PEM encoded.

func LoadSigner

func LoadSigner(t *testing.T, file string) crypto.Signer

LoadSigner loads a private key from a file. The file must be PEM encoded.

func LoadTRC

func LoadTRC(t *testing.T, file string) cppki.SignedTRC

LoadTRC loads a signed TRC from a file.

func MustExtractIA

func MustExtractIA(t *testing.T, cert *x509.Certificate) addr.IA

MustExtractIA extracts the IA from the cert's subject and verifies it is non-nil. It is the callers responsibility to make sure that this is a cert that always contains an IA.

func MustMarshalJSONToFile

func MustMarshalJSONToFile(t testing.TB, v interface{}, baseName string)

MustMarshalJSONToFile marshals v and writes the result to file testdata/baseName. If the file exists, it is truncated; if it doesn't exist, it is created. On errors, t.Fatal() is called.

func MustParseAS

func MustParseAS(s string) addr.AS

MustParseAS parses s and returns the corresponding addr.AS object. It panics if s is not valid AS representation.

func MustParseASes

func MustParseASes(list string) []addr.AS

MustParseASes parses a list of comma separated AS strings. It panics in case parsing fails.

func MustParseCIDR

func MustParseCIDR(t *testing.T, s string) *net.IPNet

MustParseCIDR parses s and returns the corresponding net.IPNet object. It fails the test if s is not a valid CIDR string.

func MustParseCIDRs

func MustParseCIDRs(t *testing.T, entries ...string) []*net.IPNet

MustParseCIDRs parses the CIDR entries and returns a list containing the parsed net.IPNet objects.

func MustParseHexString

func MustParseHexString(s string) []byte

MustParseHexString parses s and returns the corresponding byte slice. It panics if the decoding fails.

func MustParseIA

func MustParseIA(s string) addr.IA

MustParseIA parses s and returns the corresponding addr.IA object. It panics if s is not a valid ISD-AS representation.

func MustParseIAs

func MustParseIAs(list string) []addr.IA

MustParseIAs parses a list of comma separated ISD-AS strings. It panics in case parsing fails.

func MustParseIP

func MustParseIP(t *testing.T, addr string) net.IP

MustParseIP parses an IP address and returns the parsed net.IP object.

func MustParseIPPrefixes

func MustParseIPPrefixes(t *testing.T, prefixes ...string) []netip.Prefix

MustParseIPPrefixes parses the CIDR entries and returns a list containing the parsed netip.Prefix objects.

func MustParseUDPAddr

func MustParseUDPAddr(t *testing.T, s string) *net.UDPAddr

MustParseUDPAddr parses s and returns the corresponding net.UDPAddr object. It fails the test if s is not a valid UDP address string.

func MustParseUDPAddrs

func MustParseUDPAddrs(t *testing.T, entries ...string) []*net.UDPAddr

MustParseUDPAddrs parses the UPD address entries and returns a list containing the parsed net.UDPAddr objects.

func MustReadFromFile

func MustReadFromFile(t testing.TB, baseName string) []byte

MustReadFromFile reads testdata/baseName and returns the raw content. On errors, t.Fatal() is called.

func MustTempDir

func MustTempDir(dir, prefix string) (string, func())

MustTempDir creates a new temporary directory under dir with the specified prefix. If the function encounters an error it panics. The second return value is a clean-up function that can be called to recursively delete the entire directory.

func MustTempFileName

func MustTempFileName(dir, prefix string) string

MustTempFileName is a wrapper around TempFileName. The function panics if an error occurs. It is intended for tests where error handling is not necessary, and for chaining functions.

func MustWriteToFile

func MustWriteToFile(t testing.TB, b []byte, baseName string)

MustWriteToFile writes b to file testdata/baseName. If the file exists, it is truncated; if it doesn't exist, it is created. On errors, t.Fatal() is called.

func SanitizedName

func SanitizedName(t testing.TB) string

SanitizedName sanitizes the test name such that it can be used as a file name.

func TempFileName

func TempFileName(dir, prefix string) (string, error)

TempFileName creates a temporary file in dir with the specified prefix, and then closes and deletes the file and returns its name. It is useful for testing packages that care about a unique path without being able to overwrite it (e.g., UNIX domain socket addresses or databases).

func UpdateGoldenFiles

func UpdateGoldenFiles() *bool

Update registers the '-update' flag for the test.

This flag should be checked by golden file tests to see whether the golden files should be updated or not. The golden files should be deterministic. Use UpdateNonDeterminsticGoldenFiles instead, if they are not deterministic.

To update all golden files, run the following command:

go test ./... -update

To update a specific package, run the following command:

go test ./path/to/package -update

The flag should be registered as a package global variable:

var update = xtest.UpdateGoldenFiles()

func UpdateNonDeterminsticGoldenFiles

func UpdateNonDeterminsticGoldenFiles() *bool

UpdateNonDeterminsticGoldenFiles registers the '-update-non-deterministic' flag for the test.

This flag should be checked by golden file tests to see whether the non-deterministic golden files should be updated or not.

To update all golden files, run the following command:

go test ./... -update-non-deterministic

To update a specific package, run the following command:

go test ./path/to/package -update-non-deterministic

The flag should be registered as a package global variable:

var updateNonDeterministic = xtest.UpdateNonDeterminsticGoldenFiles()

func WithCredentials

func WithCredentials(client, server credentials.TransportCredentials) func(*grpcServiceOptions)

func WithInsecureCredentials

func WithInsecureCredentials() func(*grpcServiceOptions)

Types

type GRPCService

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

func NewGRPCService

func NewGRPCService(options ...GRPCServiceOption) *GRPCService

func (*GRPCService) Dial

func (s *GRPCService) Dial(ctx context.Context, addr net.Addr) (*grpc.ClientConn, error)

func (*GRPCService) Server

func (s *GRPCService) Server() *grpc.Server

func (*GRPCService) Start

func (s *GRPCService) Start(t *testing.T)

type GRPCServiceOption

type GRPCServiceOption func(*grpcServiceOptions)

type PanickingReporter

type PanickingReporter struct {
	*testing.T
}

PanickingReporter is a wrapper around the *testing.T implementation of gomock.TestReporter which panics and logs on FatalF instead of calling runtime.Goexit(). This avoids deadlocks when a child goroutine fails a mocking constraint when using gomock.

For more information, see https://github.com/golang/mock/issues/139.

func (*PanickingReporter) Fatalf

func (reporter *PanickingReporter) Fatalf(format string, args ...interface{})
