2018-05-20Drop the chain argument to GetDifficultyBen Woosley
This removes the need to include rpc/blockchain.cpp in order to put GetDifficulty under test. GetDifficulty was called in two ways: * with a guaranteed non-null blockindex * with no argument Change the latter case to be provided chainActive.Tip() explicitly.
2018-05-03Make it clear which functions that are intended to be translation unit localpracticalswift
Do not share functions that are meant to be translation unit local with other translation units. Use internal linkage for those consistently.
2018-03-19tests: Rename test suits not following the test suite naming conventionpracticalswift
The name of the fixture test suite in `src/test/foo_tests.cpp` should be `foo_tests`.
2017-11-22[Tests] Adding unit tests for GetDifficulty in blockchain.cpp.sean
blockchain.cpp has low unit test coverage. This commit is intended to start improving its code coverage to reasonable levels. One or more follow up commits will complete the task that this commit is starting (though the usefulness of this commit is not dependent upon later commits). Note that these tests were not written based upon a specification of how GetDifficulty *should* work, but rather how it actually *does* work. As a result, if there are any bugs in the current GetDifficulty implementation, these unit tests serve to lock them in rather than expose them. -- Why has blockchain.cpp been modified if this is a unit testing change? Since the existing GetDifficulty function relies on a global variable, chainActive, it was not suitable for unit testing purposes. Both the existing GetDifficulty function and the unit tests now call through to a new, more modular version of GetDifficulty that can work on any chain, not just chainActive. -- Why does blockchain_tests.cpp directly include blockchain.cpp instead of blockchain.h? While the new GetDifficulty function's signature is arguably better than the old one's, it still isn't great, and doesn't seem to warrant inclusion as part of the blockchain.h API, especially since only test code is directly using it. If a better way of exposing the new GetDifficulty function to unit tests exists, please mention it and the commit will be updated accordingly. -- Why is the test fixture named blockchain_difficulty_tests rather than blockchain_tests? The Bitcoin Core policy for naming unit test files is to match the the file under test ("blockchain" becomes "blockchain_tests"). While this commit complies with that, blockchain.cpp is a massive file, such that having all of the unit tests in one file will tend towards disorder. Since there will be a lot more tests added to this file, the intention is to divide up different types of tests into different test fixtures within the same file.
