Is there any way to get a parent value in `when` and `test` ?

var inst = yup.object({
  isBig: yup.boolean(),
  id: yup.number(),
  counter: yup.object({
     // get isBig from parent.parent in when
     time: yup.number().when('isBig', (isBig, schema) => {
       return isBig ? schema.min(1) : schema.min(1897778);
    }),
    value: yup.number().when('isBig', (isBig, schema) => {
       return isBig ? schema.min(5) : schema.min(0);
    }),
     // get id from parent.parent in test
    productId: yup().number().test('productId', 'Product option with id ${value} not found', async function (id) {
        if(this.parent.parent.id) {
            return true
        }

        ....
    })
  })
});

inst.validate({ isBig: false, count: 4 });

Can I get in nested objects get parent value in when in counter.time get isBig and in test get counter.productId get id ?

@khotey Did you ever figure a way to do this or @jquense did this ever get implemented?

From the documentation: test functions are called with a special context, or this value, that exposes some useful metadata and functions. Note that to use the this context the test function must be a function expression (function test(value) {}), not an arrow function, since arrow functions have lexical context.

this.parent: in the case of nested schema, this is the value of the parent object
