+Unity Test API
+==============
+
+-------------
+Running Tests 
+------------- 
+
+RUN_TEST(func)
+
+Each Test is run within the macro RUN_TEST.  This macro performs necessary setup before the test is called and handles cleanup and result tabulation afterwards.
+
+TEST_WRAP(function) 
+
+If the test functions call helper functions and those helper functions have the ability to make assertions, calls to those helpers should be wrapped in a TEST_WRAP macro.  This macro aborts the test if the helper triggered a failure.
+
+--------------
+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_THROW 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_THROW (message)
+
+Abort Test macro
+
+Example:
+
+main()
+{
+    if (TEST_PROTECT() == 0)
+    {
+        MyTest();
+    }
+}
+
+If MyTest calls TEST_THROW, a failure with the message provided will be inserted, and 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(message)
+
+This test is automatically marked as a failure.  The message is output stating why.
+
+------------------------------
+Numerical Assertions: Integers
+------------------------------
+
+TEST_ASSERT_EQUAL(expected, actual)
+
+Another way of calling TEST_ASSERT_EQUAL_INT
+
+TEST_ASSERT_EQUAL_INT(expected, actual)
+
+Compare two integers for equality and display errors as signed integers.
+
+TEST_ASSERT_EQUAL_UINT(expected, actual)	
+
+Compare two integers for equality and display errors as unsigned integers.
+
+TEST_ASSERT_EQUAL_HEX8(expected, actual)	
+
+Compare two integers for equality and display errors as an 8-bit hex value
+
+TEST_ASSERT_EQUAL_HEX16(expected, actual)	
+
+Compare two integers for equality and display errors as an 16-bit hex value
+
+TEST_ASSERT_EQUAL_HEX32(expected, actual)	
+
+Compare two integers for equality and display errors as an 32-bit hex value
+
+TEST_ASSERT_EQUAL_HEX(expected, actual)	
+
+Another way of calling TEST_ASSERT_EQUAL_HEX32
+
+TEST_ASSERT_INT_WITHIN(delta, expected, actual)
+
+Asserts that the actual value is within plus or minus delta of the expected value.
+
+TEST_ASSERT_EQUAL_MESSAGE(expected, actual, message)
+
+Another way of calling TEST_ASSERT_EQUAL_INT_MESSAGE
+
+TEST_ASSERT_EQUAL_INT_MESSAGE(expected, actual, message)
+
+Compare two integers for equality and display errors as signed integers.  Outputs a custom message on failure.
+
+TEST_ASSERT_EQUAL_UINT_MESSAGE(expected, actual, message)	
+
+Compare two integers for equality and display errors as unsigned integers. Outputs a custom message on failure.
+
+TEST_ASSERT_EQUAL_HEX8_MESSAGE(expected, actual, message)
+	
+Compare two integers for equality and display errors as an 8-bit hex value. Outputs a custom message on failure.
+
+TEST_ASSERT_EQUAL_HEX16_MESSAGE(expected, actual, message)
+	
+Compare two integers for equality and display errors as an 16-bit hex value. Outputs a custom message on failure.
+
+TEST_ASSERT_EQUAL_HEX32_MESSAGE(expected, actual, message)	
+
+Compare two integers for equality and display errors as an 32-bit hex value. Outputs a custom message on failure.
+
+TEST_ASSERT_EQUAL_HEX_MESSAGE(expected, actual, message)
+	
+Another way of calling TEST_ASSERT_EQUAL_HEX32_MESSAGE
+
+-----------------------------
+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.
+
+-----------------
+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_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.
+
+------------------
+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
