Overview

Package authtest implements some interfaces used by auth package to simplify unit testing.

Index

Variables

var ErrAuthenticationError = errors.New("authtest: fake Authenticate error")

ErrAuthenticationError is returned by FakeAuth.Authenticate.

func MockAuthConfig

func MockAuthConfig(ctx context.Context) context.Context

MockAuthConfig configures the auth library for unit tests environment.

You need this *only* if your tests call auth.Authenticate(...) or auth.GetRPCTransport(...). If your tests only check groups or permissions (for example when testing bodies of request handlers), use FakeState instead. See its docs for some examples.

type FakeAuth

type FakeAuth struct {
	User *auth.User // user to return in Authenticate or nil for error
}

FakeAuth implements auth.Method's Authenticate by returning predefined user.

func (FakeAuth) Authenticate

func (m FakeAuth) Authenticate(context.Context, *http.Request) (*auth.User, error)

Authenticate returns predefined User object (if it is not nil) or error.

func (FakeAuth) LoginURL

func (m FakeAuth) LoginURL(ctx context.Context, dest string) (string, error)

LoginURL returns fake login URL.

func (FakeAuth) LogoutURL

func (m FakeAuth) LogoutURL(ctx context.Context, dest string) (string, error)

LogoutURL returns fake logout URL.

type FakeDB

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

FakeDB implements authdb.DB by mocking membership and permission checks.

Initialize it with a bunch of mocks like:

db := authtest.NewFakeDB(

authtest.MockMembership("user:a@example.com", "group"),
authtest.MockPermission("user:a@example.com", "proj:realm", perm),
...

)

The list of mocks can also be extended later via db.AddMocks(...).

func NewFakeDB

func NewFakeDB(mocks ...MockedDatum) *FakeDB

NewFakeDB creates a FakeDB populated with the given mocks.

Construct mocks using MockMembership, MockPermission, MockIPWhitelist and MockError functions.

func (*FakeDB) AddMocks

func (db *FakeDB) AddMocks(mocks ...MockedDatum)

AddMocks applies a bunch of mocks to the state in the db.

func (*FakeDB) CheckMembership

func (db *FakeDB) CheckMembership(ctx context.Context, id identity.Identity, groups []string) (out []string, err error)

CheckMembership is part of authdb.DB interface.

func (*FakeDB) GetAuthServiceURL

func (db *FakeDB) GetAuthServiceURL(ctx context.Context) (string, error)

GetAuthServiceURL is part of authdb.DB interface.

func (*FakeDB) GetCertificates

func (db *FakeDB) GetCertificates(ctx context.Context, id identity.Identity) (*signing.PublicCertificates, error)

GetCertificates is part of authdb.DB interface.

func (*FakeDB) GetTokenServiceURL

func (db *FakeDB) GetTokenServiceURL(ctx context.Context) (string, error)

GetTokenServiceURL is part of authdb.DB interface.

func (*FakeDB) GetWhitelistForIdentity

func (db *FakeDB) GetWhitelistForIdentity(ctx context.Context, ident identity.Identity) (string, error)

GetWhitelistForIdentity is part of authdb.DB interface.

func (*FakeDB) HasPermission

func (db *FakeDB) HasPermission(ctx context.Context, id identity.Identity, perm realms.Permission, realm string) (bool, error)

HasPermission is part of authdb.DB interface.

func (*FakeDB) IsAllowedOAuthClientID

func (db *FakeDB) IsAllowedOAuthClientID(ctx context.Context, email, clientID string) (bool, error)

IsAllowedOAuthClientID is part of authdb.DB interface.

func (*FakeDB) IsInWhitelist

func (db *FakeDB) IsInWhitelist(ctx context.Context, ip net.IP, whitelist string) (bool, error)

IsInWhitelist is part of authdb.DB interface.

func (*FakeDB) IsInternalService

func (db *FakeDB) IsInternalService(ctx context.Context, hostname string) (bool, error)

IsInternalService is part of authdb.DB interface.

func (*FakeDB) IsMember

func (db *FakeDB) IsMember(ctx context.Context, id identity.Identity, groups []string) (bool, error)

IsMember is part of authdb.DB interface.

func (*FakeDB) Use

func (db *FakeDB) Use(ctx context.Context) context.Context

Use installs the fake db into the context.

Note that if you use auth.WithState(ctx, &authtest.FakeState{...}), you don't need this method. Modify FakeDB in the FakeState instead. See its doc for some examples.

type FakeState

type FakeState struct {
	// Identity is main identity associated with the request.
	//
	// identity.AnonymousIdentity if not set.
	Identity identity.Identity

	// IdentityGroups is list of groups the calling identity belongs to.
	IdentityGroups []string

	// IdentityPermissions is a list of (realm, permission) tuples that define
	// caller's permissions.
	IdentityPermissions []RealmPermission

	// PeerIPWhitelists is a list of IP whitelists the caller IP belongs to.
	PeerIPWhitelists []string

	// Error, if not nil, is returned by auth DB checks.
	Error error

	// FakeDB is an authdb.DB implementation to use.
	//
	// If not nil, takes precedence over IdentityGroups, IdentityPermissions,
	// PeerIPWhitelists and Error.
	FakeDB authdb.DB

	// PeerIdentityOverride may be set for PeerIdentity() to return custom value.
	//
	// By default PeerIdentity() returns Identity (i.e. no delegation is
	// happening).
	PeerIdentityOverride identity.Identity

	// PeerIPOverride may be set for PeerIP() to return custom value.
	//
	// By default PeerIP() returns "127.0.0.1".
	PeerIPOverride net.IP

	// UserCredentialsOverride may be set to override UserCredentials().
	//
	// By default UserCredentials() returns ErrNoForwardableCreds error.
	UserCredentialsOverride *oauth2.Token
}

type MockedDatum

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

MockedDatum is a return value of various Mock* constructors.

func MockError

func MockError(err error) MockedDatum

`err` may be nil, in which case the previously mocked error is removed.

func MockIPWhitelist
