pw::i2c::test::NativeResponderTestInterface Class Reference

Overview

This interface defines the contract that a backend-specific test harness (NativeResponderTest) must implement to be used with the generic pw::i2c::Responder tests.

Member Function Documentation

GetResponder()

virtual Responder & pw::i2c::test::NativeResponderTestInterface::GetResponder ( )

pure virtual

Provides access to the backend-specific responder instance. The responder should have been configured with the callbacks provided to the NativeResponderTest constructor.

SimulateInitiatorRead()

virtual Status pw::i2c::test::NativeResponderTestInterface::SimulateInitiatorRead ( ByteSpan  buffer, bool  send_stop  )

pure virtual

Simulates an I2C initiator reading data from the responder.

Parameters

buffer	The buffer into which the initiator will read data.
send_stop	If true, a STOP condition is simulated after the read.

Returns

• OK: on success, all bytes were written.
• Error code when not all the bytes could be written.

SimulateInitiatorWrite()

virtual Status pw::i2c::test::NativeResponderTestInterface::SimulateInitiatorWrite ( ConstByteSpan  write_data, bool  send_stop  )

pure virtual

Simulates an I2C initiator writing data to the responder.

Parameters

write_data	The data to be written by the initiator.
send_stop	If true, a STOP condition is simulated after the write.

Returns

• OK: on successful simulation
• Error status otherwise.
