Functional testing with Golang

Question

I have a webservice written in Golang.

I need to refactor it because it is poorly written.

I have seen Golang works with the format TestMethodName(t *testing.T). This is great for unit testing, but in my case, methods will change a lot because of the refactoring.

That's why I want to write functional testing, so that I can test each endpoint, and check that output has correct format, without being dependant of functions

How should I do it with Golang ?

Is there any framework that helps me with functional tests ? In another stack, like PHP / Laravel for instance, I can swap PostgreSQL with a SQLite, or In Memory testing, which is very practical for this kind of tests.

I don't see how the testing package "being great for unit testing" makes it unsuitable for functional tests. — Peter

as long as the input and output of functions does not change you can keep using the same tests — Pizza lord

Just because the functions are often named TestMethodName, doesn't mean you must use that naming scheme, or can't test whatever you want. Look at any large go project, and you'll see tests of all sorts, at all levels of integration. — Mr_Pink

You can test your API endpoints by using net/http/httptest package and mocking external dependencies.

See example: https://golang.org/src/net/http/httptest/example_test.go
