Testing Spark applications allows for a rapid development workflow and gives you confidence that your code will work in production. Most Spark users spin up clusters with sample data sets to develop…

For example, Spark supports Kafka hence this integration is already tested. End-to-end tests could be 2017-06-02 · We are also able to unify multiple data processing components that support Apache Spark under one readable unit testing framework and produce ‘Living Documentation’ about how the system works. Everyone from the developer to the tester all the way up to the executive stakeholders can now read and collaborate on the system tests and understand its behavior. JUnit is a framework that I use for writing both unit and integration tests. I like JUnit because it is the most popular testing framework for Java programming language. In other words, it has a lot extensions and it is easy to find solutions to your problems. By choosing Spark as a processing framework that is internally written in Scala, you will be limited in programming languages to Scala, Python, Java, C# and R. However, you become enabled to write unit and integration tests in a framework of your choice, set up a team-based development project with less painful code merges, leverage source control, build, deployment and continuous integration features.

With ScalaTest, you can mix in BeforeAndAfterAll (which I prefer generally) or BeforeAndAfterEach as @ShankarKoirala does to initialize and tear down Spark artifacts.

ATF is Automated Test Framework which is an application provided by ServiceNow to test ServiceNow Platform. ATF allows you to create and run automated tests

Note that currently the integration tests only run with Java 8. The simplest way to run the integration tests is to install and run Minikube, then run the following: Configuration of the integration As you can see, writing production-grade integration tests for Spark applications doesn’t involve any magic. It is simple, 3-steps work: Create input data, Run the application, Verify the outputs. It would be possible to use Test Driven Development, but based on my experience, it’s not the easiest way to develop Spark ETLs.

Below you find my testing strategy for Spark and Spark Streaming applications. Unit or integration tests, that is the question. Our hypothetical Spark application pulls data from Apache Kafka, apply transformations using RDDs and DStreams and persist outcomes into Cassandra or Elastic Search database. On production Spark application is deployed on YARN or Mesos cluster, and everything is glued with ZooKeeper. Deequ is built on top of Apache Spark hence it is naturally scalable for the huge amount of data. The best part is, you don’t need to know Spark in detail to use this library. Deequ provides features like — Constraint Suggestions — What to test.
