- Mock Web Server Extension
- Resource
Set of extension functions for testing rest service api interfaces. Having mocked responses into resources folder and reading and passing them into Mock Web Server is hard and lots of boiler plate code must be written to setting it up. These extensions come to help.
testImplementation 'io.github.edasich.backpack:data-test-mockwebserver-ext:LATEST_VERSION'For instance we have a response file with json format in resources folder,
inside of api-response subfolder named sample-200-api-response.json.
Note : Having a subfolder is optional
{
"title": "This is a sample",
"description": "Only for test"
}Then in test method, we can pass the mocked json as file's path into Mock Web Server along with whatever http response code you choose by calling this extension function enqueueResponseFromResourceFile.
@Test
fun `test rest service`() =
runTest {
val expectedSampleApiResponse = SampleApiResponse(
title = "This is a sample",
description = "Only for test"
)
// given
mockWebServerRule.enqueueResponseFromResourceFile(
absoluteFilePath = "api-response/sample-200-api-response.json",
code = 200
)
// when
val actualSampleApiResponse = restService.getSample().body()!!
// then
MatcherAssert.assertThat(
actualSampleApiResponse,
Matchers.`is`(expectedSampleApiResponse)
)
}Also you can create your rest service interface by calling this extension too createRestService.
@Before
fun setUp() {
restService = mockWebServerRule.createRestService(
converterFactory = GsonConverterFactory.create(),
serviceClass = SampleRestService::class.java
)
}Reading files from resources folder during test.
