// Legacy Regression tests for 0.1.0
|
||||
//
|
||||
// Note: @christopherhein added these tests and I am unsure if Amazon
|
||||
// is still using the old io.Writer append() convention.
|
||||
// Either way, I am keeping legacy (deprecated) support for it.
|
||||
//
|
||||
// All of these regression tests should still pass.
