Function Documentation

gsec_test_bias_random_uint32()

uint32_t gsec_test_bias_random_uint32

(

uint32_t

max_length

)

This method returns a uint32 that's not quite uniformly random, but good enough for tests.

• max_length: a max value the returned random number can choose.

gsec_test_copy()

void gsec_test_copy	(	const uint8_t *	src,
		uint8_t **	des,
		size_t	source_len
	)

This method copies data from a source to a destination buffer.

• src: a source buffer.
• des: a destination buffer.
• source_len: the length of source buffer to be copied from its beginning.

Definition at line 49 of file gsec_test_util.cc.

gsec_test_copy_and_alter_random_byte()

void gsec_test_copy_and_alter_random_byte	(	const uint8_t *	src,
		uint8_t **	des,
		size_t	source_len
	)

This method copies data from a source to a destination buffer, and flips one byte in the destination buffer randomly.

• src: a source buffer.
• des: a destination buffer.
• length: the length of source buffer to be copied from its beginning.

gsec_test_expect_compare_code_and_substr()

int gsec_test_expect_compare_code_and_substr	(	grpc_status_code	status1,
		grpc_status_code	status2,
		const char *	msg1,
		const char *	msg2
	)

This method compares two grpc_status_code values, and verifies if one string is a substring of the other.

• status1: the first grpc_status_code to be compared.
• status2: the second grpc_status_code to be compared.
• msg1: a string to be scanned.
• msg2: a small string to be searched within msg1.

If both checks succeed, the method returns 1 and otherwise, it returns 0.

gsec_test_random_array()

void gsec_test_random_array	(	uint8_t **	bytes,
		size_t	length
	)

This method returns an array of random bytes.

• bytes: array to hold random bytes.
• length: length of array to be populated.

Definition at line 33 of file gsec_test_util.cc.

gsec_test_random_bytes()

void gsec_test_random_bytes	(	uint8_t *	bytes,
		size_t	length
	)

This method returns random bytes of certain length.

• bytes: buffer to hold random bytes.
• length: length of buffer to be populated.
