In ExtJS 6.2, does subclasses inherit the parent config?

It doesn't seem to work for me.

Ext.define('test1', {
    config: {
        test1: {
            test1: ''
        }
    },

    constructor(config) {
        Ext.apply(this, config);

        console.log(config);
    },
});

Ext.define('test2', {
    extend: 'test1',

    config: {
        test2: ''
    },

    constructor(config) {
        this.callParent(config);

        console.log(this.config);
    },
});

Ext.create('test2', {
    test1: {
        test1: 'test1'
     },
     test2: 'test2'
});

Also it seems that on parent constructor config is undefined!

I want to have everything defined on parent class config also available in child class. And be able to set parent config when creating child class.

You have to initConfig to get the ExtJS typical configs. You get all configs inside test2.

Ext.define('test1', {
    config: {
        test1: null
    },

    constructor(config) {
        this.initConfig(config);

        return this;
    }
});

Ext.define('test2', {
    extend: 'test1',

    config: {
        test2: ''
    },

    constructor(config) {
// == > config

        this.callParent([config]);

// ==> her you can even use getTest1(), setTest1() (or test2)
    }
});

Ext.create('test2', {
    test1: {
        test1: 'test1'
    },
    test2: 'test2'
});

One workaround is to call Ext.apply(this, config); not sure if this is the correct solution.

Ext.define('test2', {
    extend: 'test1',

    config: {
        test2: ''
    },

    constructor(config) {
        this.callParent(config);

        Ext.apply(this, config);  // <-

        console.log(this.config);

        console.log(this.getTest1());
        console.log(this.getTest2());
    },
});
