Unit tests

[dktapps]

The following things should be tested:

• [x] Basic parity with appropriate pack() and unpack() codes with selected values
• [ ] Symmetry of encoding and decoding
• [x] read*() must correctly handle non-reference types by throwing an error
• [x] read*() must correctly update reference integer offset parameter if given
• [x] read*() must correctly handle not being given an offset parameter
• [x] read*() must read from the correct place when given an offset parameter
• [x] writeUnsignedVarInt() must handle negative numbers properly (i.e. it must terminate)
• [x] readUnsignedVarInt() must limit the number of bytes read and error appropriately
• [x] read*() functions must error properly when not given enough bytes
• [x] clone must work correctly on ByteBuffer
• [x] serialize and unserialize must work correctly on ByteBuffer
• [x] $buffer = new ByteBuffer($data) should behave the same as $buffer = new ByteBuffer(); $buffer->writeByteArray($data);
