The blockchain prunes seven eighths of prunable tx data. This saves about two thirds of the blockchain size, while keeping the node useful as a sync source for an eighth of the blockchain. No other data is currently pruned. There are three ways to prune a blockchain: - run monerod with --prune-blockchain - run "prune_blockchain" in the monerod console - run the monero-blockchain-prune utility The first two will prune in place. Due to how LMDB works, this will not reduce the blockchain size on disk. Instead, it will mark parts of the file as free, so that future data will use that free space, causing the file to not grow until free space grows scarce. The third way will create a second database, a pruned copy of the original one. Since this is a new file, this one will be smaller than the original one. Once the database is pruned, it will stay pruned as it syncs. That is, there is no need to use --prune-blockchain again, etc.
Running all tests
To run all tests, run:
cd /path/to/monero
make [-jn] debug-test # where n is number of compiler processes
To test a release build, replace debug-test with release-test in the previous command.
Core tests
Core tests take longer than any other Monero tests, due to the high amount of computational work involved in validating core components.
Tests are located in tests/core_tests/, and follow a straightforward naming convention. Most cases cover core functionality (block_reward.cpp, chaingen.cpp, rct.cpp, etc.), while some cover basic security tests (double_spend.cpp & integer_overflow.cpp).
To run only Monero's core tests (after building):
cd build/debug/tests/core
ctest
To run the same tests on a release build, replace debug with release.
Crypto Tests
Crypto tests are located under the tests/crypto directory.
crypto-tests.hcontains test harness headersmain.cppimplements the driver for the crypto tests
Tests correspond to components under src/crypto/. A quick comparison reveals the pattern, and new tests should continue the naming convention.
To run only Monero's crypto tests (after building):
cd build/debug/tests/crypto
ctest
To run the same tests on a release build, replace debug with release.
Daemon tests
[TODO]
Functional tests
[TODO]
Functional tests are located under the tests/functional directory.
First, run a regtest daemon in the offline mode and with a fixed difficulty:
monerod --regtest --offline --fixed-difficulty 1
Alternatively, you can run multiple daemons and let them connect with each other by using --add-exclusive-node. In this case, make sure that the same fixed difficulty is given to all the daemons.
Next, restore a mainnet wallet with the following seed and restore height 0 (the file path doesn't matter):
velvet lymph giddy number token physics poetry unquoted nibs useful sabotage limits benches lifestyle eden nitrogen anvil fewest avoid batch vials washing fences goat unquoted
Open the wallet file with monero-wallet-rpc with RPC port 18083. Finally, start tests by invoking ./blockchain.py or ./speed.py
Fuzz tests
Fuzz tests are written using American Fuzzy Lop (AFL), and located under the tests/fuzz directory.
An additional helper utility is provided contrib/fuzz_testing/fuzz.sh. AFL must be installed, and some additional setup may be necessary for the script to run properly.
Hash tests
Hash tests exist under tests/hash, and include a set of target hashes in text files.
To run only Monero's hash tests (after building):
cd build/debug/tests/hash
ctest
To run the same tests on a release build, replace debug with release.
Libwallet API tests
[TODO]
Net Load tests
[TODO]
Performance tests
Performance tests are located in tests/performance_tests, and test features for performance metrics on the host machine.
To run only Monero's performance tests (after building):
cd build/debug/tests/performance_tests
./performance_tests
If the performance_tests binary does not exist, try running make in the build/debug/tests/performance_tests directory.
To run the same tests on a release build, replace debug with release.
Unit tests
Unit tests are defined under the tests/unit_tests directory. Independent components are tested individually to ensure they work properly on their own.
To run only Monero's unit tests (after building):
cd build/debug/tests/unit_tests
ctest
To run the same tests on a release build, replace debug with release.
Writing new tests
Test hygiene
When writing new tests, please implement all functions in .cpp or .c files, and only put function headers in .h files. This will help keep the fairly complex test suites somewhat sane going forward.
Writing fuzz tests
