Types

type MockBinder

type MockBinder struct{}

MockBinder is a test double for binder.IBinder that returns a SecurityException reply from every Transact call. This allows testing generated proxy methods without a real binder driver.

func NewMockBinder

func NewMockBinder() *MockBinder

NewMockBinder creates a new MockBinder.

func (*MockBinder) Cookie

func (m *MockBinder) Cookie() uintptr

Cookie returns 0 (mock has no local binder cookie).

func (*MockBinder) Handle

func (m *MockBinder) Handle() uint32

Handle returns a fixed handle value of 42.

func (*MockBinder) Identity

func (m *MockBinder) Identity() binder.CallerIdentity

Identity returns a zero-value CallerIdentity since the mock has no real caller.

func (*MockBinder) IsAlive

func (m *MockBinder) IsAlive(_ context.Context) bool

IsAlive always returns true for the mock.

func (*MockBinder) LinkToDeath

func (m *MockBinder) LinkToDeath(
	_ context.Context,
	_ binder.DeathRecipient,
) error

LinkToDeath is a no-op for the mock.

func (*MockBinder) ResolveCode

func (m *MockBinder) ResolveCode(
	_ context.Context,
	_ string,
	_ string,
) (binder.TransactionCode, error)

ResolveCode always returns FirstCallTransaction for the mock. The mock doesn't care about transaction codes — it returns SecurityException regardless.

func (*MockBinder) Transact

func (m *MockBinder) Transact(
	_ context.Context,
	_ binder.TransactionCode,
	_ binder.TransactionFlags,
	_ *parcel.Parcel,
) (*parcel.Parcel, error)

Transact returns a reply parcel containing a SecurityException status.

func (*MockBinder) Transport

func (m *MockBinder) Transport() binder.VersionAwareTransport

Transport returns nil since there is no underlying transport.

func (*MockBinder) UnlinkToDeath

func (m *MockBinder) UnlinkToDeath(
	_ context.Context,
	_ binder.DeathRecipient,
) error

UnlinkToDeath is a no-op for the mock.

type SmokeOption

type SmokeOption func(*smokeConfig)

SmokeOption configures SmokeTestAllMethods behavior.

func WithMethodFilter

func WithMethodFilter(filter func(string) bool) SmokeOption

WithMethodFilter sets a predicate that decides whether a method should be tested. Methods for which the filter returns false are skipped.

type SmokeResult

type SmokeResult struct {
	Total    int
	Passed   int
	Panicked int
	Failed   int
}

SmokeResult summarizes the outcome of SmokeTestAllMethods.

func SmokeTestAllMethods

func SmokeTestAllMethods(
	t *testing.T,
	proxy any,
	opts ...SmokeOption,
) SmokeResult

SmokeTestAllMethods calls every exported method on proxy with zero-value arguments and classifies the results. Each method is run as a t.Run sub-test. Panics (e.g. nil interface dereference) are caught and counted, not propagated.
