This directory contains integration tests that test bitcoind and its
utilities in their entirety. It does not contain unit tests, which
can be found in [/src/test](/src/test), [/src/wallet/test](/src/wallet/test),
etc.
There are currently two sets of tests in this directory:
- [functional](/test/functional) which test the functionality of
bitcoind and bitcoin-qt by interacting with them through the RPC and P2P
interfaces.
- [util](test/util) which tests the bitcoin utilities, currently only
bitcoin-tx.
The util tests are run as part of `make check` target. The functional
tests are run by the travis continuous build process whenever a pull
request is opened. Both sets of tests can also be run locally.
Functional Test dependencies
============================
The ZMQ functional test requires a python ZMQ library. To install it:
- on Unix, run `sudo apt-get install python3-zmq`
- on mac OS, run `pip3 install pyzmq`
Running tests locally
=====================
Build for your system first. Be sure to enable wallet, utils and daemon when you configure. Tests will not run otherwise.
Functional tests
----------------
You can run any single test by calling
test/functional/test_runner.py <testname>
Or you can run any combination of tests by calling
test/functional/test_runner.py <testname1> <testname2> <testname3> ...
Run the regression test suite with
test/functional/test_runner.py
Run all possible tests with
test/functional/test_runner.py --extended
By default, tests will be run in parallel. To specify how many jobs to run,
append `--jobs=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 bitcoinds and test.* datadir on exit or error
--noshutdown Don't stop bitcoinds after the test execution
--srcdir=SRCDIR Source directory containing bitcoind/bitcoin-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 test/functional/test_runner.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 bitcoind
```
Util tests
----------
Util tests can be run locally by running `test/util/bitcoin-util-test.py`.
Use the `-v` option for verbose output.
Writing functional tests
========================
You are encouraged to write functional tests for new or existing features.
Further information about the functional test framework and individual
tests is found in [test/functional](/test/functional).
