--force-fieldtrial-params
What does --force-fieldtrial-params do?
This option can be used to force parameters of field trials when testing changes locally. The argument is a param list of (key, value) pairs prefixed by an associated (trial, group) pair. You specify the param list for multiple (trial, group) pairs with a comma separator. Example: "Trial1.Group1:k1/v1/k2/v2,Trial2.Group2:k3/v3/k4/v4" Trial names, groups names, parameter names, and value should all be URL escaped for all non-alphanumeric characters.
