Sure there is a standard, are you saying the w3 doesn't exist? The issue is that somehow people here are arguing that it is sufficient to test that you are adhering to a standard by only testing against chrome, edge and safari (two of which are the same engine). If you want test that you are adhering to a standard (if there is no testsuite available) you need to test against more than 2 independent implementations.
