Fix all the spec files at once by adding the exception handling code in support e2e.js (Cypress version 10 and above) because it is loaded before any test/spec file is evaluated. However, the true potential of Cypress testing can only be leveraged when used with cloud-based testing platforms like LambdaTest. The above example is an oversimplification, but a representative one. So there are two obvious options: In the case of cypress tetsing, block the load of newrelic scripts.
