Need for Basic sanity check for yaml files in Travis CI #2719
Description
With in Travis CI can there be a way to do have a basic sanity check for yaml's?
Like use of "=" should be catched initially itself and asked to update to ":", and other basic checks could be incorporated as well.
For eg in #2654 we can see there is issue with yaml which went in without a check and causes issues like below later.
