Question about Native Modules

[sm2017]

According to https://facebook.github.io/react-native/docs/native-modules-android.html native android modules extends ReactContextBaseJavaModule , Is the module singleton?

If I have the following method

@ReactMethod 
public void testMethod(String message, Promise promise) { 
    this.promise = promise;
}

and

MyModule.testMethod('A').then(function(result){
    console.log(result);
});

MyModule.testMethod('B').then(function(result){
    console.log(result);
});

MyModule.testMethod('C').then(function(result){
    console.log(result);
});

What happens exactly? is MyModule.testMethod('C') overwrite this.promise (the module is singleton ) OR each time the new instance of module is created and promise is a property and isolated?
