> In `FPGrowthSuite`, we only tested output with minSupport 0.5, where the expected output is hard-coded. We can add equivalent R code using the arules package to generate the expect output for validation purpose, similar to https://github.com/apache/spark/blob/master/mllib/src/test/scala/org/apache/spark/ml/regression/LinearRegressionSuite.scala#L98 and the test code in https://github.com/apache/spark/pull/7005.
