Alexander Block 48d92f116e Implement optional pretty printed stacktraces (#2420 ) * Add libbacktrace to depends This is currently only useful to extract symbols. It fails to gather stacktraces when compiled with MinGW, so we can only use it to get symbol information from a stack trace which we gathered outside of libbacktrace. * Add -mbig-obj to CXXFLAGS for MinGW builds * Implement stacktraces for C++ exceptions This is a hack and should only be used for debugging. It works by wrapping the C++ ABI __wrap___cxa_allocate_exception. The wrapper records a backtrace and stores it in a global map. Later the stacktrace can be retrieved with GetExceptionStacktraceStr. This commit also adds handlers to pretty print uncaught exceptions and signals. * Use GetPrettyExceptionStr for all unhandled exceptions * Use --enable-stacktraces in CI for linux32/linux64 * Register exception translators to pretty print exceptions in unit tests * Catch and print python exceptions when stopping nodes Otherwise the code at the bottom is never executed when nodes crash, leading to no output of debug.log files on Travis. * Remove now unneeded/unused TestCrash methods		2019-02-21 21:37:15 +03:00

README.md

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

Every pull request to the Dash Core 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 --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 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*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

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.
