 ## How to write stress tests

+Stress testing is used to detect function performance, and bears some resemblance to unit testing (which we will not get into here), however we need to pay attention to the following points:
 
 - Stress tests must follow the following format, where XXX can be any alphanumeric combination and its first letter cannot be a lowercase letter. 
 
 	func BenchmarkXXX (b *testing.B){...}
 
 - By default, `Go test` does not perform function stress tests. If you want to perform stress tests, you need to set the flag `-test.bench` with the format: `-test.bench="test_name_regex"`. For instance, to run all stress tests in your suite, you would run `go test -test.bench=".*"`. 
-- In your stress tests, please remember to use testing.BN any loop bodies, so that the tests can be run properly.
+- In your stress tests, please remember to use testing.B.N any loop bodies, so that the tests can be run properly.
 - As before, test file names must end in `_test.go`
