# Unit Testing

This part explains how to write unit tests during integration with Liquidswap Smart Contracts.

### Testing integration

To be able to run tests, you need to prepare the Liquidswap state in your test. There's a couple of utilities available to help you with that:

* `public fun initialize_liquidity_pool()` \[[source](https://github.com/pontem-network/liquidswap/blob/main/sources/test_helpers/test_pool.move#L30)]

It correctly initialize both Liquidswap and `LP<X, Y, Curve>` token of the Liquidswap. That process is pretty involved, so we provide this helper function to make it easier. Run it after the `genesis::setup()` call from Aptos Framework.

* `public fun mint_liquidity<X, Y, Curve>(lp_owner: &signer, coin_x: Coin<X>, coin_y: Coin<Y>): u64` \[[source](https://github.com/pontem-network/liquidswap/blob/main/sources/test_helpers/test_pool.move#L54)]

Adds `coin_x`, `coin_y` to the pool, and automatically deposits returning lp coins to the `lp_owner` account, handling the edge cases.

An example of the test would be:
