Cypress Integration Tests

These are end to end tests for kiali that are meant to be run against a live environment.

Prerequisites

Ensure the baseUrl field in the cypress.json file at the kiali-ui root is pointing to the server you are trying to test. By default this is localhost:3000 so if you are running kiali locally you should just need to do yarn start before running cypress.

Running tests

Tests can be run with the cypress browser:

yarn cypress

or in headless mode:

yarn cypress:run

Testing Strategies

Graph

The kiali graph is primarily a canvas element which makes it more difficult to test through query selectors with cypress. To get around this limitation, a simple way of testing visual elements is to do snapshot testing aka visual testing. This boils down to comparing an existing image of the page to a new image. If any differences exist, the test will fail. There are other ways of testing canvas elements in Cypress but they seem to involve interacting with cypress through a custom api rather than visually which is not ideal.
