Description

There are some important methods in streams that are lacking good unit-test coverage. Whilst we shouldn't strive to get 100% coverage, we should do our best to ensure sure that all important code paths are covered by unit-tests.

For contributors: you can first run ./gradlew streams:reportCoverage to get the report, which will then accessible in streams/build/reports/jacoco/test/html/index.html.
