# 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.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
ctest
```

To run the same tests on a release build, replace `debug` with `release`.

# Daemon tests

[TODO]

# Functional tests

[TODO]

# 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
