Function Documentation

TEST_F() [1/3]

alexaClientSDK::audioEncoder::test::TEST_F	(	AudioEncoderTest	,
		testTimer_startEncoding
	)

TEST_F() [2/3]

alexaClientSDK::audioEncoder::test::TEST_F	(	AudioEncoderTest	,
		test_shutdownOnBlockingWrite
	)

Test if encoding thread will exit if encoder output is not being consumed on exit.

TEST_F() [3/3]

alexaClientSDK::audioEncoder::test::TEST_F	(	AudioEncoderTest	,
		test_stopAndStartEncoder
	)

Test if encoding thread will exit and create again when stopEncoding() and startEncoding() is called in quick succession.
