Unable to implement user subscription based Push Notifications when implemented with Adapter based authentication

I have defined an Adapter based as authentication.

Doing a custom security test which works successfully.

But when I wanted to implement User Subscription based Push Notifications and added a mobile security test in authentication Config.XML I am facing lot of issues.

As I'm trying to deploy the app and test in android device. I have also included the mobile security test in android tag of application-descriptor.xml. But facing lot of issues to deploy the adapter itself after this.

Can anyone guide me on this please?

Please refer to the below code snippets which I am using

authenticationConfig.xml

    <mobileSecurityTest name="MST1">
        <testUser realm="AdapterAuthRealm"/>
        <testDeviceId provisioningType="none"/>
    </mobileSecurityTest>

    <webSecurityTest name="WST1">
        <testUser realm="AdapterAuthRealm"/>
    </webSecurityTest>

    <customSecurityTest name="Master-Password">
        <test realm="AdapterAuthRealm" isInternalUserID="true"/>
    </customSecurityTest>

Authentication was running fine till I had only the customSecurityTest being defined.

After adding web and mobile security test, there is no response when I give the credentials and click login neither from GUI side nor from the console logs side.

I have also added security test in android tag in application-descriptor.xml as below

<android securityTest="MST1" version="1.0"> 
    <worklightSettings include="false"/>        
    <pushSender key="xxxxxxxxxxx" senderId="xxxxxxxxxxxxxxx"/>

    <security>
        <encryptWebResources enabled="false"/>
        <testWebResourcesChecksum enabled="false" ignoreFileExtensions="png, jpg, jpeg, gif, mp4, mp3"/>
        <publicSigningKey/>
        <packageName/>
    </security>
</android>
