Init registers testing flags.

Main is an internal function, part of the implementation of the "go test" command.

MainStart is meant for use by tests generated by 'go test'.

BenchmarkResult contains the results of a benchmark run.

Cover records information about test coverage checking.

CoverBlock records the coverage data for a single basic block.

F is a type passed to fuzz tests.

InternalBenchmark is an internal type but exported because it is cross-package; it is part of the implementation of the "go test" command.

InternalFuzzTarget is an internal type but exported because it is cross-package; it is part of the implementation of the "go test" command.

InternalTest is an internal type but exported because it is cross-package; it is part of the implementation of the "go test" command.

M is a type passed to a TestMain function to run the actual tests.
