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. + +# 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 + +#### 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 the tests + +Individual tests can be run by directly calling the test script, eg: + +``` +test/functional/feature_rbf.py +``` + +or can be run through the test_runner harness, eg: + +``` +test/functional/test_runner.py feature_rbf.py +``` + +You can run any combination (incl. duplicates) 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, up to 4 tests will be run in parallel by test_runner. To specify +how many jobs to run, append `--jobs=n` + +The individual tests and the test_runner harness have many command-line +options. Run `test_runner.py -h` to see them all. + +#### Troubleshooting and debugging test failures + +##### Resource contention + +The P2P and RPC ports used by the bitcoind nodes-under-test are chosen to make +conflicts with other processes unlikely. However, if there is another bitcoind +process running on the system (perhaps from a previous test which hasn't successfully +killed all its bitcoind nodes), then there may be a port conflict which will +cause the test to fail. It is recommended that you run the tests on a system +where no other bitcoind processes are running. + +On linux, the test_framework will warn if there is another +bitcoind process running when the tests are started. + +If there are zombie bitcoind processes after test failure, you can kill them +by running the following commands. **Note that these commands will kill all +bitcoind processes running on the system, so should not be used if any non-test +bitcoind processes are being run.** + +```bash +killall bitcoind +``` + +or + +```bash +pkill -9 bitcoind +``` + + +##### Data directory cache + +A pre-mined blockchain with 200 blocks is generated the first time a +functional test is run and is stored in test/cache. This speeds up +test startup times since new blockchains don't need to be generated for +each test. However, the cache may get into a bad state, in which case +tests will fail. If this happens, remove the cache directory (and make +sure bitcoind processes are stopped as above): + +```bash +rm -rf cache +killall bitcoind +``` + +##### Test logging + +The tests contain logging at different levels (debug, info, warning, etc). By +default: + +- when run through the test_runner harness, *all* logs are written to + `test_framework.log` and no logs are output to the console. +- when run directly, *all* logs are written to `test_framework.log` and INFO + level and above are output to the console. +- when run on Travis, no logs are output to the console. However, if a test + fails, the `test_framework.log` and bitcoind `debug.log`s will all be dumped + to the console to help troubleshooting. + +To change the level of logs output to the console, use the `-l` command line +argument. + +`test_framework.log` and bitcoind `debug.log`s can be combined into a single +aggregate log by running the `combine_logs.py` script. The output can be plain +text, colorized text or html. For example: + +``` +combine_logs.py -c <test data directory> | less -r +``` + +will pipe the colorized logs from the test into less. + +Use `--tracerpc` to trace out all the RPC calls and responses to the console. For +some tests (eg any that use `submitblock` to submit a full block over RPC), +this can result in a lot of screen output. + +By default, the test data directory will be deleted after a successful run. +Use `--nocleanup` to leave the test data directory intact. The test data +directory is never deleted after a failed test. + +##### Attaching a debugger + +A python debugger can be attached to tests at any point. Just add the line: + +```py +import pdb; pdb.set_trace() +``` + +anywhere in the test. You will then be able to inspect variables, as well as +call methods that interact with the bitcoind nodes-under-test. + +If further introspection of the bitcoind instances themselves becomes +necessary, this can be accomplished by first setting a pdb breakpoint +at an appropriate location, running the test to that point, then using +`gdb` to attach to the process and debug. + +For instance, to attach to `self.node[1]` during a run: + +```bash +2017-06-27 14:13:56.686000 TestFramework (INFO): Initializing test directory /tmp/user/1000/testo9vsdjo3 +``` + +use the directory path to get the pid from the pid file: + +```bash +cat /tmp/user/1000/testo9vsdjo3/node1/regtest/bitcoind.pid +gdb /home/example/bitcoind <pid> +``` + +Note: gdb attach step may require `sudo` + +### 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). diff --git a/test/config.ini.in b/test/config.ini.in new file mode 100644 index 0000000000..35ee092be4 --- /dev/null +++ b/test/config.ini.in @@ -0,0 +1,18 @@ +# Copyright (c) 2013-2016 The Bitcoin Core developers +# Distributed under the MIT software license, see the accompanying +# file COPYING or http://www.opensource.org/licenses/mit-license.php. + +# These environment variables are set by the build process and read by +# test/functional/test_runner.py and test/util/bitcoin-util-test.py + +[environment] +SRCDIR=@abs_top_srcdir@ +BUILDDIR=@abs_top_builddir@ +EXEEXT=@EXEEXT@ + +[components] +# Which components are enabled.

A + stop-start takes several seconds, so doing it several times blows up the + runtime of the test. +- Set the `self.setup_clean_chain` variable in `set_test_params()` to control whether + or not to use the cached data directories. The cached data directories + contain a 200-block pre-mined blockchain and wallets for four nodes. Each node + has 25 mature blocks (25x50=1250 BTC) in its wallet. +- When calling RPCs with lots of arguments, consider using named keyword + arguments instead of positional arguments to make the intent of the call + clear to readers. + +#### RPC and P2P definitions + +Test writers may find it helpful to refer to the definitions for the RPC and +P2P messages. These can be found in the following source files: + +- `/src/rpc/*` for RPCs +- `/src/wallet/rpc*` for wallet RPCs +- `ProcessMessage()` in `/src/net_processing.cpp` for parsing P2P messages + +#### Using the P2P interface + +- `mininode.py` contains all the definitions for objects that pass +over the network (`CBlock`, `CTransaction`, etc, along with the network-level +wrappers for them, `msg_block`, `msg_tx`, etc). + +- P2P tests have two threads. One thread handles all network communication +with the bitcoind(s) being tested (using python's asyncore package); the other +implements the test logic. + +- `P2PConnection` is the class used to connect to a bitcoind. `P2PInterface` +contains the higher level logic for processing P2P payloads and connecting to +the Bitcoin Core node application logic. For custom behaviour, subclass the +P2PInterface object and override the callback methods. + +- Call `network_thread_start()` after all `P2PInterface` objects are created to +start the networking thread. (Continue with the test logic in your existing +thread.) + +- Can be used to write tests where specific P2P protocol behavior is tested. +Examples tests are `p2p_unrequested_blocks.py`, `p2p_compactblocks.py`. + +#### Comptool + +- Comptool is a Testing framework for writing tests that compare the block/tx acceptance +behavior of a bitcoind against 1 or more other bitcoind instances. It should not be used +to write static tests with known outcomes, since that type of test is easier to write and +maintain using the standard BitcoinTestFramework. + +- Set the `num_nodes` variable (defined in `ComparisonTestFramework`) to start up +1 or more nodes. If using 1 node, then `--testbinary` can be used as a command line +option to change the bitcoind binary used by the test. If using 2 or more nodes, +then `--refbinary` can be optionally used to change the bitcoind that will be used +on nodes 2 and up. + +- Implement a (generator) function called `get_tests()` which yields `TestInstance`s. +Each `TestInstance` consists of: + - A list of `[object, outcome, hash]` entries + * `object` is a `CBlock`, `CTransaction`, or + `CBlockHeader`. `CBlock`'s and `CTransaction`'s are tested for + acceptance. `CBlockHeader`s can be used so that the test runner can deliver + complete headers-chains when requested from the bitcoind, to allow writing + tests where blocks can be delivered out of order but still processed by + headers-first bitcoind's. + * `outcome` is `True`, `False`, or `None`. If `True` + or `False`, the tip is compared with the expected tip -- either the + block passed in, or the hash specified as the optional 3rd entry. If + `None` is specified, then the test will compare all the bitcoind's + being tested to see if they all agree on what the best tip is. + * `hash` is the block hash of the tip to compare against. Optional to + specify; if left out then the hash of the block passed in will be used as + the expected tip. This allows for specifying an expected tip while testing + the handling of either invalid blocks or blocks delivered out of order, + which complete a longer chain. + - `sync_every_block`: `True/False`. If `False`, then all blocks + are inv'ed together, and the test runner waits until the node receives the + last one, and tests only the last block for tip acceptance using the + outcome and specified tip. If `True`, then each block is tested in + sequence and synced (this is slower when processing many blocks). + - `sync_every_transaction`: `True/False`. Analogous to + `sync_every_block`, except if the outcome on the last tx is "None", + then the contents of the entire mempool are compared across all bitcoind + connections. If `True` or `False`, then only the last tx's + acceptance is tested against the given outcome. + +- For examples of tests written in this framework, see + `p2p_invalid_block.py` and `feature_block.py`. + +### test-framework modules + +#### [test_framework/authproxy.py](test_framework/authproxy.py) +Taken from the [python-bitcoinrpc repository](https://github.com/jgarzik/python-bitcoinrpc). + +#### [test_framework/test_framework.py](test_framework/test_framework.py) +Base class for functional tests. + +#### [test_framework/util.py](test_framework/util.py) +Generally useful functions. + +#### [test_framework/mininode.py](test_framework/mininode.py) +Basic code to support P2P connectivity to a bitcoind. + +#### [test_framework/comptool.py](test_framework/comptool.py) +Framework for comparison-tool style, P2P tests. + +#### [test_framework/script.py](test_framework/script.py) +Utilities for manipulating transaction scripts (originally from python-bitcoinlib) + +#### [test_framework/blockstore.py](test_framework/blockstore.py) +Implements disk-backed block and tx storage. + +#### [test_framework/key.py](test_framework/key.py) +Wrapper around OpenSSL EC_Key (originally from python-bitcoinlib) + +#### [test_framework/bignum.py](test_framework/bignum.py) +Helpers for script.py + +#### [test_framework/blocktools.py](test_framework/blocktools.py) +Helper functions for creating blocks and transactions. diff --git a/test/functional/combine_logs.py b/test/functional/combine_logs.py new file mode 100755 index 0000000000..3ca74ea35e --- /dev/null +++ b/test/functional/combine_logs.py @@ -0,0 +1,114 @@ +#!/usr/bin/env python3 +"""Combine logs from multiple bitcoin nodes as well as the test_framework log. + +This streams the combined log output to stdout.
