How do I write integration tests with URLSession in Swift?

Integration tests with URLSession in Swift can help ensure that your app's network functionalities work as expected. This is especially important for features that rely on web services and APIs. Below is an example of how you can create a simple integration test using URLSession.

import XCTest @testable import YourApp class NetworkIntegrationTests: XCTestCase { func testFetchDataFromAPI() { let expectation = XCTestExpectation(description: "Download data from api") // Replace with your actual URL let url = URL(string: "https://api.yourservice.com/data")! let task = URLSession.shared.dataTask(with: url) { (data, response, error) in XCTAssertNil(error, "Error should be nil") XCTAssertNotNil(data, "Data should not be nil") // Add more assertions here to validate the response data. expectation.fulfill() } task.resume() wait(for: [expectation], timeout: 10.0) } }
