       go - tool for managing Go source code


       The  'go  test'  command  expects  to  find  test, benchmark, and example functions in the
       "*_test.go" files corresponding to the package under test.

       A test function is one named TestXXX (where XXX is any alphanumeric  string  not  starting
       with a lower case letter) and should have the signature,

             func TestXXX(t *testing.T) { ... }

       A benchmark function is one named BenchmarkXXX and should have the signature,

             func BenchmarkXXX(b *testing.B) { ... }

       An  example  function  is  similar  to a test function but, instead of using *testing.T to
       report success or failure, prints output to  os.Stdout  and  os.Stderr.   That  output  is
       compared  against  the function's "Output:" comment, which must be the last comment in the
       function body (see example below). An example with no such comment, or with no text  after
       "Output:" is compiled but not executed.

       Godoc displays the body of ExampleXXX to demonstrate the use of the function, constant, or
       variable XXX.  An example of a method M with receiver type T or *T  is  named  ExampleT_M.
       There  may be multiple examples for a given function, constant, or variable, distinguished
       by a trailing _xxx, where xxx is a suffix not beginning with an upper case letter.

       Here is an example of an example:

             func ExamplePrintln() {
                 Println("The output of\nthis example.")
                 // Output: The output of
                 // this example.

       The entire test file is presented as  the  example  when  it  contains  a  single  example
       function,  at  least  one  other function, type, variable, or constant declaration, and no
       test or benchmark functions.

       See the documentation of the testing package for more information.
