how to extract some paramater from body

[Amr Salem]

i want to extract some of the body parameters and save it as var so i can use it in another test of with same test lets say i wanna post some items after its posted it will get new ID i wanna extract then ID so i can delete this item in the next test of within same test

`describe ('Backend Validation', function () {
frisby.globalSetup({
request: {
headers: {
'cookie': 'role',
'company-service': 'company'
}
}
});

fit('1- Verify user can create ite, with valid data',function () {
    return frisby
        .post('https://xxxxv.xxxxx.com/api/customers/features', {
            customerFeatureTypeId: 1,
            customerFeatureTypeValue: "123007",
            AccountId: "31111"
        })
        .expect('status',200)
        .inspectBody()
});`

inspct body output :
Body: {"id":963,"customerFeatureTypeId":1,"customerFeatureTypeValue":"123007","AccountId":"31111"}

i want to extract this value of id (963)

You can do this by nesting tests. It's in the README here: https://github.com/vlucas/frisby#nested-dependent-http-calls

@vlucas
i have tried the following method as u mentioned but im getting this error below could provide a sample how to solve it

    fit('1- Verify user can create IMEI with valid data',function () {
        return frisby
            .post('https://dev.example', {
                customerFeatureTypeId: 1,
                customerFeatureTypeValue: D.randomNumber,
                AccountId: "31111"
            })
            .expect('status',200)
            .expect('json', '*',
                {id: Joi.number(),
                    customerSecurityFeatureTypeId: 1,
                    customerSecurityFeatureTypeValue: D.randomNumber
                })
            .then(function (res) {
                let postId = res.json[0].id;
                return frisby
                    .patch('https://dev.example.com/api/customers/features',
                        {
                            customerSecurityFeaturesToUpdate: [],
                            customerSecurityFeaturesToDelete: [{id: postId}]
                        })
            })
            .expect('status',200)
            .inspectBody()
    });

You are using json along with Joi objects:

.expect('json', '*',
                {id: Joi.number(),

Joi can only be used with jsonTypes.
