MockWebServer Extensions

The MockWebServer Extensions, provides a convenient solution for testing HTTP clients by extending MockWebServer functionalities. With easy integration into your testing environment, it allows for seamless mocking of server responses, facilitating comprehensive testing of HTTP client behaviors.

Usage

Create a variable with MockWebServerRule in the test class.

@get:Rule
var mockWebServer: MockWebServerRule = MockWebServerRule()

To mock a request, use register method.

mockWebServer.register {
    expectThat(it).url.path.isEqualTo("/fact")
    jsonResponse("""{"fact": "Example fact about your cat."}""")
}

Requirements

Download

Add it in your root build.gradle at the end of repositories or in settings.gradle:

repositories {
    maven { url 'https://jitpack.io' }
}

Add the dependency:

dependencies {
    androidTestImplementation 'com.github.appunite.MockWebServer-Extensions:mockwebserver-extensions:0.2.2'
    androidTestImplementation 'com.github.appunite.MockWebServer-Extensions:mockwebserver-request:0.2.2'
    implementation 'com.github.appunite.MockWebServer-Extensions:mockwebserver-interceptor:0.2.2'
}

Add a Network Security Configuration

dependencies {
    debugImplementation 'com.github.appunite.MockWebServer-Extensions:mockwebserver-allow-mocking:0.2.2'
}

Add TestInterceptor to your HTTP Client.

// Ktor
val client = HttpClient(OkHttp) {
    engine {
        addInterceptor(TestInterceptor)
    }
}

// Retrofit
val okHttpClient = OkHttpClient.Builder()
    .addInterceptor(TestInterceptor)
    .build()

val retrofit = Retrofit.Builder()
    .baseUrl(baseUrl)
    .client(okHttpClient)
    .build()

Optional Assertions using okhttp

dependencies {
    androidTestImplementation 'com.github.appunite.MockWebServer-Extensions:mockwebserver-assertions:0.2.2'
}

You can check full example in the app module. And more examples in the Loudius - Android playground in the app-shared-tests module.
