## Build and Test

Prefer building in sbt over maven:

- **Building Spark**: [docs/building-spark.md](docs/building-spark.md)
  - SBT build instructions: See the ["Building with SBT"](docs/building-spark.md#building-with-sbt) section
  - SBT testing: See the ["Testing with SBT"](docs/building-spark.md#testing-with-sbt) section
  - Running individual tests: See the ["Running Individual Tests"](docs/building-spark.md#running-individual-tests) section

- **PySpark Testing**: [python/docs/source/development/testing.rst](python/docs/source/development/testing.rst)
