HttpMockResponseInterceptor

A Mock response interceptor lib, which can mock response for UI test, Instrumentation test and other test as well, directly from retrofit api class using simple annotation.

Using HttpMockResponseInterceptor, you can fetch data from creating local json files using retrofit Api class by simply using one additional annotation.

Dependencies

Add the Jitpack source to project or settings.gradle:

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

// or in settings.gradle

pluginManagement {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}
dependencyResolutionManagement {

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

Add the following dependency to your build.gradle(module) file:

  dependencies {
    ...
    implementation 'com.github.devggaurav:HttpMockResponseInterceptor:v1.0.2'
}

Init

HttpMockResponseInterceptor.Builder(context.assets).build()

// or

HttpMockResponseInterceptor.Builder(context.assets).isMockEnabled {
    true // false if you want to get data from server or pass your build variant e.g BuildConfig.DEBUG
}.build()

// or using DI

@Provides
fun provideMockingInterceptor(
    @ApplicationContext context: Context
): HttpMockResponseInterceptor {
    return HttpMockResponseInterceptor.Builder(context.assets).isMockEnabled {
        true
    }.build()
}

Usage

Define your endpoint and just add @MockSuccessResponse annotation for getting data from local json filename provided

@GET(ApiConstants.END_POINTS)
@MockSuccessResponse(fileName = "characters_response.json")
suspend fun getCharacter(): List<Character>

Create Mock Json File in assets Create response you are expecting from api to test like in characters_response.json

{
  "dummyjson": "Dummy value"
}

Updates

Working on handling and passing multiple files to handle success and error response for testcases.
