This macro performs necessary setup before the test is called and handles cleanup and result tabulation afterwards. + +Ignoring Tests +-------------- + +There are times when a test is incomplete or not valid for some reason. At these times, TEST_IGNORE can be called. Control will immediately be returned to the caller of the test, and no failures will be returned. + + TEST_IGNORE() + +Ignore this test and return immediately + + TEST_IGNORE_MESSAGE (message) + +Ignore this test and return immediately. Output a message stating why the test was ignored. + +Aborting Tests +-------------- + +There are times when a test will contain an infinite loop on error conditions, or there may be reason to escape from the test early without executing the rest of the test. A pair of macros support this functionality in Unity. The first `TEST_PROTECT` sets up the feature, and handles emergency abort cases. `TEST_ABORT` can then be used at any time within the tests to return to the last `TEST_PROTECT` call. + + TEST_PROTECT() + +Setup and Catch macro + + TEST_ABORT() + +Abort Test macro + +Example: + + main() + { + if (TEST_PROTECT() == 0) + { + MyTest(); + } + } + +If MyTest calls `TEST_ABORT`, program control will immediately return to `TEST_PROTECT` with a non-zero return value. + + +Unity Assertion Summary +======================= + +Basic Validity Tests +-------------------- + + TEST_ASSERT_TRUE(condition) + +Evaluates whatever code is in condition and fails if it evaluates to false + + TEST_ASSERT_FALSE(condition) + +Evaluates whatever code is in condition and fails if it evaluates to true + + TEST_ASSERT(condition) + +Another way of calling `TEST_ASSERT_TRUE` + + TEST_ASSERT_UNLESS(condition) + +Another way of calling `TEST_ASSERT_FALSE` + + TEST_FAIL() + TEST_FAIL_MESSAGE(message) + +This test is automatically marked as a failure. The message is output stating why. + +Numerical Assertions: Integers +------------------------------ + + TEST_ASSERT_EQUAL_INT(expected, actual) + TEST_ASSERT_EQUAL_INT8(expected, actual) + TEST_ASSERT_EQUAL_INT16(expected, actual) + TEST_ASSERT_EQUAL_INT32(expected, actual) + TEST_ASSERT_EQUAL_INT64(expected, actual) + +Compare two integers for equality and display errors as signed integers. A cast will be performed +to your natural integer size so often this can just be used. When you need to specify the exact size, +like when comparing arrays, you can use a specific version: + + TEST_ASSERT_EQUAL_UINT(expected, actual) + TEST_ASSERT_EQUAL_UINT8(expected, actual) + TEST_ASSERT_EQUAL_UINT16(expected, actual) + TEST_ASSERT_EQUAL_UINT32(expected, actual) + TEST_ASSERT_EQUAL_UINT64(expected, actual) + +Compare two integers for equality and display errors as unsigned integers. Like INT, there are +variants for different sizes also. + + TEST_ASSERT_EQUAL_HEX(expected, actual) + TEST_ASSERT_EQUAL_HEX8(expected, actual) + TEST_ASSERT_EQUAL_HEX16(expected, actual) + TEST_ASSERT_EQUAL_HEX32(expected, actual) + TEST_ASSERT_EQUAL_HEX64(expected, actual) + +Compares two integers for equality and display errors as hexadecimal. Like the other integer comparisons, +you can specify the size... here the size will also effect how many nibbles are shown (for example, `HEX16` +will show 4 nibbles). + + _ARRAY + +You can append `_ARRAY` to any of these macros to make an array comparison of that type. Here you will +need to care a bit more about the actual size of the value being checked. You will also specify an +additional argument which is the number of elements to compare. For example: + + TEST_ASSERT_EQUAL_HEX8_ARRAY(expected, actual, elements) + + TEST_ASSERT_EQUAL(expected, actual) + +Another way of calling TEST_ASSERT_EQUAL_INT + + TEST_ASSERT_INT_WITHIN(delta, expected, actual) + +Asserts that the actual value is within plus or minus delta of the expected value. This also comes in +size specific variants. + + +Numerical Assertions: Bitwise +----------------------------- + + TEST_ASSERT_BITS(mask, expected, actual) + +Use an integer mask to specify which bits should be compared between two other integers. High bits in the mask are compared, low bits ignored. + + TEST_ASSERT_BITS_HIGH(mask, actual) + +Use an integer mask to specify which bits should be inspected to determine if they are all set high. High bits in the mask are compared, low bits ignored. + + TEST_ASSERT_BITS_LOW(mask, actual) + +Use an integer mask to specify which bits should be inspected to determine if they are all set low. High bits in the mask are compared, low bits ignored. + + TEST_ASSERT_BIT_HIGH(bit, actual) + +Test a single bit and verify that it is high. The bit is specified 0-31 for a 32-bit integer. + + TEST_ASSERT_BIT_LOW(bit, actual) + +Test a single bit and verify that it is low. The bit is specified 0-31 for a 32-bit integer. + +Numerical Assertions: Floats +---------------------------- + + TEST_ASSERT_FLOAT_WITHIN(delta, expected, actual) + +Asserts that the actual value is within plus or minus delta of the expected value. + + TEST_ASSERT_EQUAL_FLOAT(expected, actual) + TEST_ASSERT_EQUAL_DOUBLE(expected, actual) + +Asserts that two floating point values are "equal" within a small % delta of the expected value. + +String Assertions +----------------- + + TEST_ASSERT_EQUAL_STRING(expected, actual) + +Compare two null-terminate strings. Fail if any character is different or if the lengths are different. + + TEST_ASSERT_EQUAL_STRING_LEN(expected, actual, len) + +Compare two strings. Fail if any character is different, stop comparing after len characters. + + TEST_ASSERT_EQUAL_STRING_MESSAGE(expected, actual, message) + +Compare two null-terminate strings. Fail if any character is different or if the lengths are different. Output a custom message on failure. + + TEST_ASSERT_EQUAL_STRING_LEN_MESSAGE(expected, actual, len, message) + +Compare two strings. Fail if any character is different, stop comparing after len characters. Output a custom message on failure. + +Pointer Assertions +------------------ + +Most pointer operations can be performed by simply using the integer comparisons above. However, a couple of special cases are added for clarity. + + TEST_ASSERT_NULL(pointer) + +Fails if the pointer is not equal to NULL + + TEST_ASSERT_NOT_NULL(pointer) + +Fails if the pointer is equal to NULL + +Memory Assertions +----------------- + + TEST_ASSERT_EQUAL_MEMORY(expected, actual, len) + +Compare two blocks of memory. This is a good generic assertion for types that can't be coerced into acting like +standard types... but since it's a memory compare, you have to be careful that your data types are packed. + +_MESSAGE +-------- + +you can append _MESSAGE to any of the macros to make them take an additional argument. This argument +is a string that will be printed at the end of the failure strings. This is useful for specifying more +information about the problem. +
