Network mocking for testing the WordPress mobile apps



To use this library in your project, you must set it up as a subtree. From the root of your main project, add the subtree:

$ git subtree add --prefix=libs/mocks [email protected]:wordpress-mobile/WordPressMocks.git develop

This will create a new directory, libs/mocks, containing the contents of this repository.

At this point, you can add it to your project's root settings.gradle:

include ':libs:mocks:WordPressMocks'

and to your main app module's build.gradle dependencies:

dependencies {
    androidTestImplementation('com.github.tomakehurst:wiremock:2.23.2') {
        exclude group: 'com.fasterxml.jackson.core', module: 'jackson-core'
        exclude group: 'org.apache.httpcomponents', module: 'httpclient'
        exclude group: 'org.apache.commons', module: 'commons-lang3'
        exclude group: 'asm', module: 'asm'
        exclude group: 'org.json', module: 'json'
    androidTestImplementation 'org.apache.httpcomponents:httpclient-android:'
    androidTestImplementation project(path:':libs:mocks:WordPressMocks')


To start the WireMock server as a standalone process, you can run it with this command:

./scripts/start.sh 8282

Here 8282 is the port to run the server on. It can now be accessed from http://localhost:8282.


You can fetch the latest changes made to this library into your project using:

$ git subtree pull --prefix=libs/mocks [email protected]:wordpress-mobile/WordPressMocks.git develop --squash

And you can push your own changes upstream to WordPressMocks using:

$ git subtree push --prefix=libs/mocks [email protected]:wordpress-mobile/WordPressMocks.git branch-name

Note: You can add this repository as a remote to simplify the git subtree push/pull commands:

$ git remote add mockslib [email protected]:wordpress-mobile/WordPressMocks.git

This will allow to use this form instead:

$ git subtree pull --prefix=libs/mocks mockslib develop --squash

Creating a mock file

The JSON files used by WireMock to handle requests and are located in src/main/assets. To generate one of these files you're first going to want to set up Charles Proxy (or similar) to work with your Android emulator. If you've never done this I found this article to be a good place to start. Once you've done that you'll want to walk through the specfic flow you're testing and store the JSON contents of the necessary responses in the jsonBody field of the response field in the mock file.

Here's an example of what this might look like,

    "request": {
        "urlPattern": "/rest/v1.1/me/",
        "method": "GET"
    "response": {
        "status": 200,
        "jsonBody": {
            // ..... Your response here
        "headers": {
            "Content-Type": "application/json",
            "Connection": "keep-alive",
            "Cache-Control": "no-cache, must-revalidate, max-age=0"

These files are used to match network requests while the tests are being run. For more on request matching with WireMock check out their documentation.
