You can write a bunch of tests like these and simulate similar conditions!įeel free to explore more at the official repository of mockwebserver. This lets us know that our parsing is done correctly. 😃Īnd we’re done, that’s it! We have successfully tested our API calls. Then we can go ahead and instantiate our logger and define the logging level we are interested in: HttpLoggingInterceptor logger new HttpLoggingInterceptor () tLevel () In this example, we are only interested in seeing the headers. Let us now create a demo application, which displays information from Github APIs.Ĭonsider the following snippet for which the test case has to be written public T fetchResponseAsObject(Class classType) //Adding below lines to the test method var httpUrl = mockWebServer.url("/").toString() GithubApiClient restClient = new GithubApiClient(httpUrl) Īfter doing the above changes our test ran successfully.

Thus interacting with MockWebServer from our test cases allows our code to use real HTTP calls to a local endpoint and we thus get the benefit of testing the intended HTTP interactions. For instrumented tests on Android that go through multiple screens to test a user flow, I find myself enqueueing multiple requests so I get the following code: server.enqueue(request1) server.enqueue(request2) server.enqueue(request3) Fo. A mock web server is a program that mocks the behavior of an actual remote server but doesn’t make calls over the internet. This testing library is built by the Square Team to easily test how the apps behave when making API calls. Before we see its demonstration, let us first understand : What is MockWebServer? I am writing this post to help and encourage other fellow coders to use this library for testing the API calls in their applications.

I did not know much before actually using it. My senior advised me to use MockWebServer for writing these API test cases. We all are very much familiar with the fact that it’s not a good practice to invoke the actual API for test cases. I was required to write the test case for the code that includes the API calls. I was recently working on a Java-based application that involves HTTP calls. It has become inevitable to write a test case of every feature of the application you develop to ensure its expected behavior at any instant.

Writing test cases is a crucial part of development in any software development field. It’s so much greater because those tests enable you to improve the design. Good architecture and design are important, but the effect of a robust suite of tests is an order of magnitude greater. For a good writeup on this topic, check out the documentation on replacing callbacks with suspendCoroutine.Nothing makes a system more flexible than a suite of tests. How do you ensure that your test runs to completion (with a timeout, obviously) when you are running in an asynchronous context? Fortunately, we have the capabilities of Kotlin coroutines in the tests, which makes this remarkably easy. 3 4 Licensed under the Apache License, Version 2.0 (the 'License') 5 you may not use this file. You have to deal with the async nature of the API. 1 / 2 Copyright 2012-2017 the original author or authors. The asynchronous worker is not finished by the time the assertions are done. The requestUrl is a HttpUrl object, which is part of the okhttp3 library. My library ensures that the options I pass in are encoded properly, and that the request is turned into the appropriate URL. Otherwise it doesnt know what to send back. What other checks? That depends on the requirements of your library. Second, to get responses from the mock web server, you need to enqueue the expected responses as MockResponse s.

I’m expecting my users to call something fun test_network_request_with_callback () My library always connects to the same URL and uses the context to grab the API key.

Adjust your library so it is testing friendly.

Since I’ve already got the relevant JSON (which I use to test the model decoding), I can use that to produce a fake service.ĭoing this requires an understanding of three steps: Square, the same people that brought you OkHttp, also produce a mock web server that you can use to mock the network connection. How can I test the asynchronous network calls in a repeatable manner?įortunately, there’s a library for that. Since I am writing a network client library, I need to go a step further and deal with the network connection itself. MockWebServer server new MockWebServer() server.enqueue(new MockResponse().setBody(hello, world)) server.start() Bus bus Mockito.mock(Bus.class).

In my last article, I looking at mocking the Android context and other Android specific libraries.

I’m writing a network library for Android at the moment, and specifically looking at unit tests. Unit testing asynchronous Android network libraries
