testing.AllocsPerRun
// AllocsPerRun returns the average number of allocations during calls to f.
// Although the return value has type float64, it will always be an integral value.
//
// To compute the number of allocations, the function will first be run once as
// a warm-up. The average number of allocations over the specified number of
// runs will then be measured and returned.
//
// AllocsPerRun sets GOMAXPROCS to 1 during its measurement and will restore
// it before returning.

testing.Benchmark
// Benchmark benchmarks a single function. It is useful for creating
// custom benchmarks that do not use the "go test" command.
//
// If f depends on testing flags, then Init must be used to register
// those flags before calling Benchmark and before calling flag.Parse.
//
// If f calls Run, the result will be an estimate of running all its
// subbenchmarks that don't call Run in sequence in a single benchmark.

// CoverMode reports what the test coverage mode is set to. The

testing.Coverage
// Coverage reports the current code coverage as a fraction in the range [0, 1].
// If coverage is not enabled, Coverage returns 0.
//
// When running a large set of sequential test cases, checking Coverage after each one
// can be useful for identifying which test cases exercise new code paths.
// It is not a replacement for the reports generated by 'go test -cover' and
// 'go tool cover'.

testing.Init

// new functionality is added to the testing package.
