The Vespa system test framework is an automatic testing tool for creating and running system tests. It is loosely based upon the methodology used in JUnit and similar unit test frameworks, but it has added functionality for testing at system level using multiple nodes. It is written in pure Ruby.
Repo layout: Library files that contain the framework itself are in lib/, the tests are in tests/ and utilities and automatic runners are in bin/.
Multinode testing is well supported since the framework is largely based upon RPC calls using DRb (distributed ruby). Methods for feeding data, checking an online index or doing a query and so on are executed in the context of one of the nodes in the Vespa installation. Each of the nodes must be running a ruby process called node_server.rb that acts as a server for the RPC calls.
Before running system tests, build and install Vespa following the steps in the development guide: Vespa development on CentOS Stream 8.
Follow the run system tests section of the development guide.
Developed system tests can be tested locally using Docker Swarm.
Initialize Docker Swarm if not done previously:
$ docker swarm init
Build Docker image with updated files and execute:
$ docker build --file docker/Dockerfile --tag ${USER}-systemtests .
$ bin/run-tests-on-swarm.sh --consoleoutput --image ${USER}-systemtests --nodes 1 --file search/basicsearch/basic_search.rb
For information about the capabilities of run-tests-on-swarm.sh:
$ bin/run-tests-on-swarm.sh --help
