I want to send a POST request in Cypress that triggers the validation to reject the request
According to Postman, the body of the response looke like this:
"code": "validation_error",
"message": "Validation error, please see fields property for details",
"fields":
{
"TariffData[rate_gp]": " Invalid rate_gp. Expected: 9.35. Imported: 19.35"
}
I am interested in the "fields" section, so I tried to assert with this code:
const api_key = require('../../fixtures/contracts/api_test_client1.json')
const body1 = require('../../fixtures/contracts/body_test_client1.json')
describe('test POST/client validation', () => {
it('send POST/client request', function () {
cy.request({
method: 'POST',
url: Cypress.env('staging_url') + '/service/clients',
headers: {
'API-KEY': api_key,
},
body: body1,
failOnStatusCode:false
})
.then(response => {
expect(response.status).to.eq(400)
expect(response.body.fields).to.contain('"TariffData[rate_gp]": " Invalid rate_gp. Expected: 9.35. Imported: 19.35"')
})
)}
)}
Yet this leads to an error:
AssertionError
object tested must be an array, a map, an object, a set, a string, or a weakset, but object given
Yes, the error message ends there. Any ideas how I can make an assertion that the response contains this message?
I think you just want to present the expected value as an object, not as a string
expect(response.body.fields)
.to.contain({
"TariffData[rate_gp]": " Invalid rate_gp. Expected: 9.35. Imported: 19.35"
})
If you looks at the docs chaijs API they show, for example
expect({a: 1, b: 2, c: 3}).to.include({a: 1, b: 2});
and contain is a synonym for include
You could also try to.deep.equal, as it seems you are specifying the total fields property
expect(response.body.fields)
.to.deep.eq({
"TariffData[rate_gp]": " Invalid rate_gp. Expected: 9.35. Imported: 19.35"
})
