Hi Juan, StreamingMultipleProgramsTestBase is in the testing scope. Thus, is it not bundled in the normal jars. You would have to add the flink-test-utils_2.10 module.
It is true that there is no guide. There is https://github.com/ottogroup/flink-spector for testing streaming pipelines. For unit tests and integration tests please have a look at the Flink source code which contains many such tests. -Max On Wed, Nov 2, 2016 at 4:58 PM, Juan Rodríguez Hortalá <juan.rodriguez.hort...@gmail.com> wrote: > Hi, > > I'm new to Flink, and I'm trying to write my first unit test for a simple > DataStreams job.
