let decoder = JSONDecoder()
let hoge = try! decoder.decode(Hoge.self, from: data)
hoge Stub hoge

5. Json 😄
hoge
let hoge: Hoge = TestDataHelper
.testData(forResource: "Hoge", ofType: "json")

6. Json -
class TestDataHelper {
static func testData<T: Decodable>(forResource resource: String, ofType type: String) -> T {
let url = Bundle(for: TestDataHelper.self).url(forResource: resource, withExtension: type)!
let data = try! Data(contentsOf: url)
let decoder = JSONDecoder()
return try! decoder.decode(T.self, from: data)
}
}

7. Response HTTP Stub🤔
var responses = [authError, successWithAccessToken, success]
stub(condition: isHost("example.com")) { request in
return responses.removeFirst()

// ...
HTTPStub.deactivate()
responses

9. Response HTTP Stub -
struct HTTPStub {
static func activate(condition: @escaping OHHTTPStubsTestBlock,
