Russell Yanofsky 47e9659ecf [qa] Fix bug in compactblocks v2 merge Bug caused the wait_for_block_announcement to be called on the wrong node, leading to nondeterminism and occasional test failures. Bug was introduced in merge commit: `d075479` Merge #8882: [qa] Fix race conditions in p2p-compactblocks.py and sendheaders.py Underlying commits which conflicted were: `27acfc1` [qa] Update p2p-compactblocks.py for compactblocks v2 `6976db2` [qa] Another attempt to fix race condition in p2p-compactblocks.py The first commit changed the test_compactblock_construction function signature and second commit added code which wasn't updated during the merge to use the new arguments. Suhas Daftuar <sdaftuar@chaincode.com> noticed the bug and suggested the fix.		2016-11-02 15:35:11 -04:00

README.md

The pull-tester folder contains a script to call multiple tests from the rpc-tests folder.

Every pull request to the bitcoin 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

The python3-zmq library is required. On Ubuntu or Debian it can be installed via:

sudo apt-get install python3-zmq

OS X

pip3 install pyzmq

Running tests

You can run any single test by calling

qa/pull-tester/rpc-tests.py <testname>

Or you can run any combination of tests by calling

qa/pull-tester/rpc-tests.py <testname1> <testname2> <testname3> ...

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 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 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:

rm -rf cache
killall bitcoind

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.
