- golang unit test failure expected zero, but got: 'null\n'
- First I'm trying to learn golang. I try to use testifypackage to unit test my handler in golang. When running my test I get this error -> Expected nil but got: "null\n".

- What is the difference between mapped interface {} and type structure {}?
- I just read that map[Type]interface{} specifies a map of keys of type Type with value any, which is interface{}. Isn't this almost the same as defining a struct, i.e. typeNamestruct{key1;value1,....,keyn:valuen}? What is the difference between these two types of mappings? I read https://www.digitalocean.com/community/tutorials/how-to-use-json-in-go but I still don't understand the difference. Or we define ma in a more general way

- Generic type definition for unmarshalling structs into slices
- I have an API that normally returns an array as an object containing the array. Take the following example: {"items":{"number":3,"item":[{...}//Notrelevant]}} The API does this in dozens of places, each time using a different The name. You are guaranteed to have only two keys when this happens: one of them is a number and the other is an array. This makes the resulting structure rather unpleasant to use, since you have to constantly browse through unnecessary levels of fields. I essentially want my Go interface to pretend it has this format: {

- Golang uses handlers to create mock databases and uses interfaces to call the database
- I'm trying to implement unit testing for my registration handlers and database calls. However, it throws a panic error on the database call in my registered handler. It is a simple registration handler that receives json containing username, password and email. I would then use a select statement to check if that username is a duplicate within the signup handler itself. This all works when I send my post request to this handler. However, when I actually unit tested it, it didn't work and threw me two error messages. I feel like this is because the database is not initialized in the test environment, but I don't know how to do this without using a third party framework to mock the database. mistake
