Mediation Test Suite Beta

The AdMob Mediation Test Suite allows you to test whether you have correctly configured your application and ad units to be able to display ads from third-party networks via AdMob mediation.

This guide outlines how to use the AdMob Mediation Test Suite in your Android app. The first step is integrating the tool into your app.

Prerequisites

  • Android SDK 4.0 (API level 14) or later.

  • Google Play services 9.8.0 or later.

Installation

Using Gradle

Copy the following required dependencies into your apps build.gradle file:

dependencies {
    // You should already have the ads dependency in your app.
    implementation 'com.google.android.gms:play-services-ads:17.0.0'
    implementation 'com.google.android.ads:mediation-test-suite:0.9.1'
}

Include the google() repository in your top-level build.gradle file:

// Top-level build file where you can add configuration options common to all
// sub-projects/modules.

buildscript {

   repositories {
       google()
       jcenter()
   }
   dependencies {
       classpath 'com.android.tools.build:gradle:3.1.1'

       // NOTE: Do not place your application dependencies here; they belong
       // in the individual module build.gradle files
   }
}

allprojects {
   repositories {
       google()
       jcenter()
   }
}

Launching the Mediation Test Suite

You need to present your AdMob app ID to the Mediation Test Suite. You can find the App ID for your app in the AdMob UI.

MediationTestSuite.launch(MainActivity.this, "Your application ID");

The tool opens with the following disclaimer:

Tick the checkbox and press Agree to proceed.

You're then presented with a list of ad units for your account, separated into two tabs: Failing Ad Units and Working Ad Units.

The Failing Ad Units list is separated into Missing Components and Configuration Errors:

After all of an ad unit's networks are tested successfully, the ad unit will move from the Failing tab to the Working tab. If you don't see a list of ad units, either the network call failed or no ad units were found.

If you want to search the list of ad units, press the search icon at the top and enter a string of an ad unit ID. You can also search by network name or by ad format.

The screen indicates, for a given ad unit, whether:

  • the SDK is installed
  • the adapter is installed
  • any required manifest entries are properly configured

Select an ad unit to move to the Ad Unit Details screen.

Ad Unit Details

This screen shows the details for the ad unit, including the ad unit ID, the ad format, and the mediation waterfall configured for the ad unit:

Note the following aspects on this screen:

Ad Source Summary

For each ad source, there are indicators showing whether the SDK and adapter is installed, any required manifest entries are found, and the result of the last test for this configuration in this session.

Note that for custom events, a Custom Event: Your custom event label is used. The adapter status indicator for a custom event will be positive if the class you've specified for the custom event is found. You can load and view ads for custom events in the same way as other networks.

Search

Pressing the search icon presents a search screen where you can search for ad sources according to their name.

Batch testing

Each ad source can be selected to be tested in a batch by checking the checkbox to the left of the ad source name. A new option then appears in the navigation bar:

Press the Load Ads button in the top right to load ads for the selected ad sources in sequence. A progress indicator is displayed while testing takes place. Pressing the back icon in the top left clears the selection.

Loading and displaying ads

Tap on an ad source entry to see the ad source details screen:

The screen indicates, for the given ad source, whether:

  • the SDK is installed
  • the adapter is installed
  • any required manifest entries are properly configured
  • the parameters for the configuration have been entered in the AdMob console

After you've installed all required components, you can proceed to test loading an ad. Tap on Load Ad to send an ad request to the ad source's SDK. Once the ad request completes, an update saying whether the request succeeded or failed is presented.

If the request failed, check your console logs for messages from the SDK being tested.

If the request succeeded:

  • For banner ads, the ad is shown inline.
  • For interstitial or rewarded ads, you can show the ad by tapping on Show Ad.

    The ad opens in a new screen, for example:

When you return to the Ad Unit Details screen, the results of the last time you tested the ad in the ad units list screen are displayed. The successfully loaded ad sources are moved to the bottom of the list surfacing the ad sources needing further testing. Note that these results are only stored for the duration of the session.

Configuring ad requests with network extras (optional)

Certain mediated networks, such as Vungle, require or have the option to provide a custom network extras bundle to provide additional information to requests to their network. If you need to provide network extras for your mediation requests you can set an ad request for the test suite to use using the MediationTestSuite.setAdRequest() static method:

Java

AdRequest requestBuilder = new AdRequest.Builder();
...
// Set your network extras for your chosen networks here.
// i.e for each network extras bundle, call
// 'requestBuilder.addNetworkExtrasBundle(<network adapter class>, <network extras bundle>)'
...
MediationTestSuite.setAdRequest(requestBuilder.build());

Kotlin

val requestBuilder = AdRequest.Builder()
...
// Set your network extras for your chosen networks here.
// i.e for each network extras bundle, call
// 'requestBuilder.addNetworkExtrasBundle(<network adapter class>, <network extras bundle>)'
...
MediationTestSuite.setAdRequest(requestBuilder.build())

Ensure that you do this before launching the mediation test suite.

This enables you to instantiate and configure an ad request with any required extras, which the test suite can then use in its request to the mediated network.

Frequently Asked Questions

Does the disclaimer show every time?
Yes, we do this intentionally as a reminder that you should turn on test mode for your mediation ad sources.
Why do I see AdMob multiple times on the Ad Unit details page?
If multiple mediation groups target the same ad unit, we combine all of the groups together. For example, you may see multiple AdMob entries and possibly multiple of other ad sources. Even inside the same mediation group, a mediation partner can be defined up to 3 times.
Which networks / ad sources are supported by the mediation test suite?
The test suite works for all open source and versioned adapters as well as custom event adapters. The ad networks in our open source initiative are listed on our mediation page.
