package main

    fmt.Println(common.Logger) // prints some pointer related things which means logger is initialized

}

func TestMain(m *testing.M) {

package car

func TestMyFunc(t *testing.T) {

    **t.Log(common.Logger)               // When i run go test ./... this Prints nil , Why ?**

    // Doing some tests

}

由于这个 common.Logger.Println("some data") 到处都给出零指针错误根据我的理解,一旦 Logger 被初始化,它应该是可用的,因为它是一个全局变量。我肯定在这里遗漏了一些微妙的东西。请帮忙
