// This file sets up the variables used, including testInitFns.
|
||||
// Each file should add initialization that should be performed
|
||||
// after flags are parsed.
|
||||
//
|
||||
// init is a multi-step process:
|
||||
// - setup vars (handled by init functions in each file)
|
||||
// - parse flags
|
||||
// - setup derived vars (handled by pre-init registered functions - registered in init function)
|
||||
// - post init (handled by post-init registered functions - registered in init function)
|
||||
// This way, no one has to manage carefully control the initialization
|
||||
// using file names, etc.
|
||||
//
|
||||
// Tests which require external dependencies need the -tag=x parameter.
|
||||
// They should be run as:
|
||||
// go test -tags=x -run=. <other parameters ...>
|
||||
// Benchmarks should also take this parameter, to include the sereal, xdr, etc.
|
||||
// To run against codecgen, etc, make sure you pass extra parameters.
|
||||
// Example usage:
|
||||
// go test "-tags=x codecgen" -bench=. <other parameters ...>
|
||||
//
|
||||
// To fully test everything:
|
||||
// go test -tags=x -benchtime=100ms -tv -bg -bi -brw -bu -v -run=. -bench=.
|
||||
|
||||
// Handling flags
|
||||
// codec_test.go will define a set of global flags for testing, including:
|
||||
// - Use Reset
|
||||
// - Use IO reader/writer (vs direct bytes)
|
||||
// - Set Canonical
|
||||
// - Set InternStrings
|
||||
// - Use Symbols
|
||||
//
|
||||
// This way, we can test them all by running same set of tests with a different
|
||||
// set of flags.
|
||||
//
|
||||
// Following this, all the benchmarks will utilize flags set by codec_test.go
|
||||
// and will not redefine these "global" flags.
