The [pull-tester](/qa/pull-tester/) folder contains a script to call multiple tests from the [rpc-tests](/qa/rpc-tests/) folder. Every pull request to the litecoin repository is built and run through the regression test suite. You can also run all or only individual tests locally. Test dependencies ================= Before running the tests, the following must be installed. Unix ---- `python3-zmq` and `litecoin_scrypt` are required. On Ubuntu or Debian they can be installed via: ``` sudo apt-get install python3-zmq pip3 install litecoin_scrypt ``` OS X ------ ``` pip3 install pyzmq pip3 install litecoin_scrypt ``` Running tests ============= You can run any single test by calling qa/pull-tester/rpc-tests.py Or you can run any combination of tests by calling qa/pull-tester/rpc-tests.py ... Run the regression test suite with qa/pull-tester/rpc-tests.py Run all possible tests with qa/pull-tester/rpc-tests.py -extended By default, tests will be run in parallel. To specify how many jobs to run, append `-parallel=n` (default n=4). If you want to create a basic coverage report for the rpc test suite, append `--coverage`. Possible options, which apply to each individual test run: ``` -h, --help show this help message and exit --nocleanup Leave litecoinds and test.* datadir on exit or error --noshutdown Don't stop litecoinds after the test execution --srcdir=SRCDIR Source directory containing litecoind/litecoin-cli (default: ../../src) --tmpdir=TMPDIR Root directory for datadirs --tracerpc Print out all RPC calls as they are made --coveragedir=COVERAGEDIR Write tested RPC commands into this directory ``` If you set the environment variable `PYTHON_DEBUG=1` you will get some debug output (example: `PYTHON_DEBUG=1 qa/pull-tester/rpc-tests.py wallet`). A 200-block -regtest blockchain and wallets for four nodes is created the first time a regression test is run and is stored in the cache/ directory. Each node has 25 mature blocks (25*50=1250 BTC) in its wallet. After the first run, the cache/ blockchain and wallets are copied into a temporary directory and used as the initial test state. If you get into a bad state, you should be able to recover with: ```bash rm -rf cache killall litecoind ``` Writing tests ============= You are encouraged to write tests for new or existing features. Further information about the test framework and individual rpc tests is found in [qa/rpc-tests](/qa/rpc-tests).
