--- # One way to use the config file is to generate multiple scenarios with # variations on some known parameters. If most of the scenarios have a # parameter at one particular value, it can make sense to establish that as # the default, then we only need to list the changes from that default. # See the gltf test config for a real use-case scenarios: default: # currently supported data types for the testUtils methods: # float pi : 3.14159 # int onlyEvenPrime : 2 # string transmogrifierOutput : "foo" # sequence fibonacciSeq : - 1 - 1 - 2 - 3 - 5 # an example override for a given item scenario2: transmogrifierOutput : "bar"
