## Percy Visual Testing
We also support visual testing via Percy, this extracts the DOM from Cypress and renders it using custom renderers
for Safari, Firefox, Chrome & Edge, allowing us to spot visual regressions before they become release regressions.
Right now we run it as part of the standard Pull Request CI automation but due to only having 25k screenshots/month,
and each `cy.percySnapshot()` call results in 8 screenshots (4 browsers, 2 sizes) this could quickly be exhausted and
at that point we would likely run it on a CRON interval or before releases.
Each `cy.percySnapshot()` call results in 8 screenshots (4 browsers, 2 sizes) this can quickly be exhausted and
so we only run Percy testing on `develop` and PRs which are labelled `X-Needs-Percy`.
To record a snapshot use `cy.percySnapshot()`, you may have to pass `percyCSS` into the 2nd argument to hide certain
elements which contain dynamic/generated data to avoid them cause false positives in the Percy screenshot diffs.
