## Running crypto Perl tests
|
||||
|
||||
Crypto tests require the Math::GMP Perl library, make sure it is installed on you system before running the tests.
|
||||
|
||||
Installing dependencies (using cpan):
|
||||
|
||||
```
|
||||
cpan
|
||||
cpan> install Math::BigInt::GMP
|
||||
cpan> install Digest::Keccak
|
||||
```
|
||||
|
||||
Running tests:
|
||||
|
||||
```
|
||||
TESTPATH=/path/to/monero/tests
|
||||
cd $TESTPATH
|
||||
perl -I $TESTPATH cryptotest.pl
|
||||
```
|
||||
|
||||
Important: must include test path for perl to import cryptolib.pl

# Core tests

## Running core tests
|
||||
|
||||
Monero uses the Google C++ Testing Framework (`gtest`) to write unit, integration and functional tests for core and other features of the project.
|
||||
`gtest` runs on top of cmake, and you can run all tests by:
|
||||
To run all tests, run:
|
||||
|
||||
```
|
||||
cd /path/to/monero

|
||||
|
||||
To test a release build, replace `debug-test` with `release-test` in the previous command.
|
||||
|
||||
One can also run individual test suites by building monero, then running `ctest` in test suite folders.
|
||||
# Core tests
|
||||
|
||||
Run only the hash 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.h` contains test harness headers
|
||||
- `main.cpp` implements 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

# 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 /path/to/monero

make [-j#] debug

## Writing new tests
|

# Libwallet API tests

Based on local tests and Google's guide on creating [simple tests with gtest](https://github.com/google/googletest/blob/master/googletest/docs/Primer.md#simple-tests)
|
||||
[TODO]
|
||||
|
||||
Tests consist of a test harness (defined with the TEST() macro), and the test body consisting of gtest assertions.

||||
# Net Load tests

# 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):
|
||||
|
||||
```
|
||||
TEST(test_case_name, test_name) {
|
||||
... test body ...
|
||||
|
||||
}
|
||||
cd build/debug/tests/performance_tests
|
||||
./performance_tests
|
||||
```
|
||||
|
||||
As an example in Monero's [crypto unit test](./unit_tests/crypto.cpp):
|
||||
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):
|
||||
|
||||
```
|
||||
TEST(Crypto, Ostream)
|
||||
{
|
||||
EXPECT_TRUE(is_formatted<crypto::hash8>());
|
||||
EXPECT_TRUE(is_formatted<crypto::hash>());
|
||||
EXPECT_TRUE(is_formatted<crypto::public_key>());
|
||||
EXPECT_TRUE(is_formatted<crypto::secret_key>());
|
||||
EXPECT_TRUE(is_formatted<crypto::signature>());
|
||||
EXPECT_TRUE(is_formatted<crypto::key_derivation>());
|
||||
EXPECT_TRUE(is_formatted<crypto::key_image>());
|
||||
}
|
||||
|
||||
cd build/debug/tests/unit_tests
|
||||
ctest
|
||||
```
|
||||
|
||||
The assertions inside the test harness are a bit complex, but fairly straightforward.
|
||||
To run the same tests on a release build, replace `debug` with `release`.
|
||||
|
||||
- `is_formatted<T>()` is a polymorphic function that accepts the various types of structs defined in [crypto/hash.h](../src/crypto/hash.h).
|
||||
# Writing new tests
|
||||
|
||||
Just above the test harness, we have the definition for `is_formatted`:
|
||||
## Test hygiene
|
||||
|
||||
```
|
||||
template<typename T>
|
||||
bool is_formatted()
|
||||
{
|
||||
T value{};
|
||||
|
||||
static_assert(alignof(T) == 1, "T must have 1 byte alignment");
|
||||
static_assert(sizeof(T) <= sizeof(source), "T is too large for source");
|
||||
static_assert(sizeof(T) * 2 <= sizeof(expected), "T is too large for destination");
|
||||
std::memcpy(std::addressof(value), source, sizeof(T));
|
||||
|
||||
std::stringstream out;
|
||||
out << "BEGIN" << value << "END";
|
||||
return out.str() == "BEGIN<" + std::string{expected, sizeof(T) * 2} + ">END";
|
||||
}
|
||||
```
|
||||
|
||||
`T value {}` produces the data member of the struct (`hash8` has `char data[8]`), which runs a number of tests to ensure well structured hash data.
|
||||
|
||||
Let's write a new test for the keccak function:
|
||||
|
||||
```
|
||||
bool keccak_harness()
|
||||
{
|
||||
size_t inlen = sizeof(source);
|
||||
int mdlen = (int)sizeof(md);
|
||||
int ret = keccak(source, inlen, md, mdlen);
|
||||
if (md[0] != 0x00)
|
||||
{
|
||||
return true;
|
||||
}
|
||||
else if (!ret)
|
||||
{
|
||||
return true;
|
||||
}
|
||||
else
|
||||
{
|
||||
return false;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
This is a basic test that ensures `keccak()` returns successfully when given proper input. It reuses the `source` array for input, and a new byte array `md` for storing the hash digest. Full source is in the [crypto unit test](./unit_tests/crypto.cpp).
|
||||
|
||||
Now let's create a new test harness:
|
||||
|
||||
```
|
||||
TEST(Crypto, Keccak)
|
||||
{
|
||||
# ...
|
||||
EXPECT_TRUE(keccak_harness());
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
This creates a new test under the `Crypto` test case named `Keccak`. The harness includes one assertion `EXPECT_TRUE(keccak_harness())`, which invokes `keccak_harness()`. More complex logic can be added to test various functionality of the `Keccak` library.
|
||||
|
||||
To run the new test:
|
||||
|
||||
```
|
||||
cd /path/to/monero
|
||||
make -jn debug # if no debug build exists
|
||||
cd build/debug/tests/unit_test
|
||||
make -jn
|
||||
make -jn test
|
||||
```
|
||||
|
||||
# Fuzz tests
|
||||
|
||||
## Running fuzz tests
|
||||
|
||||
```
|
||||
cd /path/to/monero
|
||||
make [-jn] fuzz # where n is number of compiler processes
|
||||
```
|
||||
|
||||
or
|
||||
|
||||
```
|
||||
cd path/to/monero
|
||||
./contrib/fuzz_testing/fuzz.sh
|
||||
```
|
||||
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.
