It avoids dividing by 8 when deserializing a tx, which is a slow operation, and multiplies by 8 when verifying and extracing the amount, which is much faster as well as less frequent |

Running all tests
To run all tests, run:
cd /path/to/wownero
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 Wownero 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 Wownero's core tests (after building):
cd build/debug/tests/core_tests
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 Wownero'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_tests directory.
Building all the tests requires installing the following dependencies:
pip install requests psutil monotonic
First, run a regtest daemon in the offline mode and with a fixed difficulty:
wownerod --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
Parameters
Configuration of individual tests.
Mining test
The following environment variables may be set to control the mining test:
MINING_NO_MEASUREMENT- set to anything to use large enough and fixed mining timeouts (use case: very slow PCs and no intention to change the mining code)MINING_SILENT- set to anything to disable mining logging
For example, to customize the run of the functional tests, you may run the following commands from the build directory:
export MINING_NO_MEASUREMENT=1
ctest -V -R functional_tests_rpc
unset MINING_NO_MEASUREMENT
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 Wownero'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 Wownero's performance tests (after building):
cd build/debug/tests/performance_tests
./performance_tests
The path may be build/Linux/master/debug (adapt as necessary for your platform).
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 Wownero'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
[TODO]
