e9e939108 [tests] Check connectivity before sending in assumevalid.py (John Newbery)

Pull request description:

  assumevalid.py would try to send over a closed P2P connection in a loop,
  hitting the following failure many times:

  `TestFramework.mininode (ERROR): Cannot send message. No connection to node!`

  The test still passed, but this is a lot of noise in the test log.

  Just check that the connection is open before trying to send.

This directory contains integration tests that test dashd and its utilities in their entirety. It does not contain unit tests, which can be found in /src/test, /src/wallet/test, etc.

There are currently two sets of tests in this directory:

  • functional which test the functionality of dashd and dash-qt by interacting with them through the RPC and P2P interfaces.
  • util which tests the dash utilities, currently only dash-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 dashds and test.* datadir on exit or error
  --noshutdown          Don't stop dashds after the test execution
  --srcdir=SRCDIR       Source directory containing dashd/dash-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*500=12500 DASH) 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 dashd

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.
