- * @fileoverview Test cases for jspb's binary protocol buffer reader.

- * There are two particular magic numbers that need to be pointed out -
- * 2^64-1025 is the largest number representable as both a double and an
- * unsigned 64-bit integer, and 2^63-513 is the largest number representable as
- * both a double and a signed 64-bit integer.
- *
- * Test suite is written using Jasmine -- see http://jasmine.github.io/
