Okay so in the first write i gonna to show you how to implementation Unit Testing in Go, absolutely this is very ez to learn. So lets do it.

Create Package

so i created package name is helper, but if you wanna to create another package name it`s not a problem.

Like the examples above, i made function simple named Hello World. if we`re trying to test it, then it should be done with Test.go.

Next, Go has a method (t *testing.T) and then follow the code below.

Result

if we wanna to run this code, we got to the helper folder first.

In above, we create a logic which only contains an error by using the panic function.

In Go, we can perform an error other than panic, we can use t.Fail() and t.FailNow() .

It`s the difference when using t.Fail() and t.FailNow()

First, we change in Hello_World.go

Next, we create other function in Hello_World_test.go

Result :

So we got this, thx for read and sorry for the mistakes, Enjoy.
