John Bailey / Mbed 2 deprecated CircularBufferTest

Tests for the circular buffer library

Dependencies:   CircularBuffer TestSupportLite mbed

Uses TestSupportLite and implements tests for CircularBuffer library. Output looks something like:

[001] {X} Empty buffer: getSize()
[002] {X} Empty buffer: read()
[003] {X} Empty buffer: peek()
[004] {X} Empty buffer: isEmpty()
[005] {X} Empty buffer: isFull()
[006] {X} Empty buffer: capacity()
[007] {X} Empty buffer: write() single byte
[008] {X} Single-byte buffer: getSize()
[009] {X} Single-byte buffer: peek()
[010] {X} Single-byte buffer: isEmpty()
[011] {X} Single-byte buffer: isFull()
[012] {X} Single-byte buffer: capacity()
[013] {X} Single-byte buffer: read()
[014] {X} Empty buffer: getSize()
[015] {X} Empty buffer: read()
[016] {X} Empty buffer: peek()
[017] {X} Empty buffer: isEmpty()
[018] {X} Empty buffer: isFull()
[019] {X} Empty buffer: capacity()
