Bug.

What is the current behavior?

const schema =  new mongoose.Schema({
   some_field: Number,
}, {
    toObject: { virtuals: true },
    toJSON: { virtuals: true },
})
schema.virtual('test.a', function() {
    return 1;
});
schema.virtual('test.b', function() {
    return 2;
})

///
console.log(model.toJSON()); // don't see test object
{
    some_field: 1
}

What is the expected behavior?

{
    some_field: 1,
    test: {a:1,b:1}
}

but when model.test.a -> works, toJSON -> not
Please mention your node.js, mongoose and MongoDB version.

schema.virtual("x")
.get(function getX() {
	return this.test.x;
})
.set(function setX(x) {
	this.test.x = x;
});

Confirmed, thanks for the detailed repro script. Will fix ASAP.

const mongoose = require('mongoose');

const schema =  new mongoose.Schema({
   some_field: Number,
}, {
    toObject: { virtuals: true },
    toJSON: { virtuals: true },
})
schema.virtual('test.a', function() {
    return 1;
});
schema.virtual('test.b', function() {
    return 2;
})

const Model = mongoose.model('Test', schema);

///
console.log((new Model()).toJSON()); // don't see test object
