A Clojure library designed to test Dqlite, an embedded SQL database with Raft consensus.
The tests run concurrent operations to some shared data from different nodes in a Dqlite cluster, checking that the operations preserve the consistency properties defined in each test. During the tests, various combinations of nemeses can be added to interfere with the database operations and exercise the database's consistency protocols.
To run a single test, try
lein run test --workload sets --nemesis kill --time-limit 60 --test-count 1 --concurrency 2n
To run the full suite, use
lein run test-all
See lein run test --help and lein run test-all --help for options.
- append Checks for dependency cycles in append/read transactions
- set concurrent unique appends to a single table
- none no nemesis
- kill kills random Dqlite test application processes
- partition network partitions
- pause process pauses
- member remove or re-add a node
Time to run test, usually 60, 180, ... seconds
Times to run test, should >= 1
Number of threads. 2n means "twice the number of nodes", and is a good default.
