9f5ab670e7c8165f161ec44dbd95778c5515ece0 tests: Use descriptor that requires both legacy and segwit (Andrew Chow) 8a04a386f75d099f4b9864b0cdf7f26442b5801f tests: Calculate input weight more accurately (Andrew Chow) Pull request description: The external input tests with specifying input weight would sometimes result in a test failure because it would add 2 to the calculated byte size in order to account for some of the variation in signature and script sizes. However 1 in 128 signatures are actually 1 byte smaller than we expect, so the difference between the actual signature size and our calculated size becomes 3 bytes which is outside of the tolerance of `assert_fee_amount` and would thus cause the test failure. To resolve this, the 2 byte buffer is reduced to 1 byte, so in the above scenario, the difference is 2 bytes which is within the tolerance of `assert_fee_amount`. Additionally, instead of putting a fixed size that we assume is the correct size for the length of the compact size length prefix of data, we actually get the length of the compact size uint. Lastly, the size calculation for a scriptWitness was simply incorrect and used fields that did not exist. This is fixed, and the test slightly modified so that it also produces a scriptWitness.

What is Bitcoin?
Bitcoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Core is the name of open source software which enables the use of this currency.

License
Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.
Development Process
The master
branch is regularly built (see doc/build-*.md
for instructions) and tested, but it is not guaranteed to be
completely stable. Tags are created
regularly from release branches to indicate new official, stable release versions of Bitcoin Core.
The https://github.com/bitcoin-core/gui repository is used exclusively for the development of the GUI. Its master branch is identical in all monotree repositories. Release branches and tags do not exist, so please do not fork that repository unless it is for development reasons.
The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.
Testing
Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.
Automated Testing
Developers are strongly encouraged to write unit tests for new code, and to
submit new unit tests for old code. Unit tests can be compiled and run
(assuming they weren't disabled in configure) with: make check
. Further details on running
and extending unit tests can be found in /src/test/README.md.
There are also regression and integration tests, written
in Python.
These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py
The CI (Continuous Integration) systems make sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.
Manual Quality Assurance (QA) Testing
Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.
Translations
Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.
Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.
Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
