Is there a simple way to test API calls and test the response of that calls? For now we do stuck at a simple xml response from within the reponse itself. We like to use xpath (cypress plugin) to crawl the xml like:
cy.request(`${DOCUMENT_FACADE}`).then((response) => {
//response is a valid JSON and its body property holds a string (xml)
cy.get(response.body).xpath("//*[name() = 'myName']") //this fails by "Not a DOM Object"
//Then we tried to give it a DOM object
var parser = new DOMParser(),
doc = parser.parseFromString(response.body, 'text/xml');
cy.get(doc).xpath("//*[name() = 'myName']").should('have.length', 1) //fails with "expected undefined to have a length of 1 but got 0
});
Maybe we totally got something wrong about this quite important part of testing I assume.
You definitely need the DOMParser, otherwise you're just chopping up a string which xpath won't do too well.
But cy.get(doc) is using the DOM as a selector on the previously loaded page (which is not loaded).
You might get it done with cy.wrap(doc), which wraps that whole document and passes it to .xpath().
Or you might need to extract the body first cy.wrap(doc).its('body').xpath().
