Unit Test 를 이용해서 Async API Call 테스트

source Code

func test_duplicateCheck() {
        var result:[String:Any]?
        
        let expectation = self.expectation(description: "calling duplicate check")
        
        APIManager.shared.requestDuplicateCheck(phoneNumber: "010-9041-7421", email: "dmammmm@naver.com")
        { response in
            result = response
            print("returned something from api call")
            
            expectation.fulfill()
            // Marks the expectation as having been met
        }
        
        waitForExpectations(timeout: 10, handler: nil)
        XCTAssertNotNil(result)
    }
