Since Cypress.io starts a browser to run the end-to-end tests, your Google Analytics tracking calls (also from other analytics services like plausible.io) are made, and you don’t want to have wrong analytics.
Looking through cypress’ documentation I finally found the blockHosts option that can be specified in your cypress.json configuration file.
Simply blacklist *.google-analytics.com by adding an entry to cypress.json like this:
{
"blockHosts": "*.google-analytics.com",
"video": false
}
But I want to specify more than one host to block
Simply specify blockHosts as an array, as the documentation says
By passing a string or array of strings you can block requests made to one or more hosts.
For example, to block calls to *.google-analytics.com and *.plausible.io, simply write:
{
"blockHosts": ["*.google-analytics.com", "*.plausible.io"]
}
Update 2021-06-23
The blacklistHosts configuration option has been renamed to blockHosts.
