i can only find rating.dat,movies.dat and ratings.dat or movies.csv,rating.csv on MovieLens . Where can i find train and test data?

Many datasets in the LibSVM format can be found here: https://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/. I believe that libFM can read those, and they are already split into a training and test set.

For recent MovieLens data you have to split the data yourself. See section named "Cross Validation" in http://files.grouplens.org/datasets/movielens/ml-latest-small-README.html.
