Hi all, When I was trying to write a test on my spark application I met
```
Error:(14, 43) not found: type LocalSparkContext
class HyperANFSuite extends FunSuite with LocalSparkContext {
```
At the source code of spark-core I could not found "LocalSparkContext",
thus I wonder how to write a test like [this] (
https://github.com/apache/spark/blob/master/graphx/src/test/scala/org/apache/spark/graphx/lib/ConnectedComponentsSuite.scala
)
