How to Test Functions in the Main Package?

Testing Functions in the Main Package

When testing functions defined in the main package, it's essential to include all relevant files in the testing command. In the example provided, the main.go and main_test.go files should both be specified on the command line.

Additionally, ensure that the test function follows the naming convention TestXXX and takes a pointer to testing.T as an argument. Modifying the main_test.go file as follows will resolve the error:

package main

import "testing"

func TestFoo(t *testing.T) {
    t.Error(foo())
}

When running the following command:

go test *.go

The tests should pass.
