Test Suite

This is the test suite for the Mero contracts.

To run the full test suite, run:

brownie test

Components of the Mero protocol may be tested in either development or mainnet-fork mode. By default, the tests will run in development mode.

To run the tests in mainnet-fork mode, run:

brownie test --network mainnet-fork

Test Suite Set Up

By default (i.e. brownie test) the full test suite will be run. Note that there is a set of common tests, which are applied to all liquidity pools by default. If a specific pool is to be tested via the --pool command line argument (see below), then only the specified pool will be tested against the common tests.

Depending on the underlying token of a liquidity pool, the pool will be tested against either the erc20 or eth tests.

The tests that are located outside of the common, erc20 and eth directories are using a DAI liquidity pool by default (this should not affect the tests), unless specified otherwise through the --pool flag.

Testing Pool Types

Liquidity pools belong to one of two types depending on the underlying asset: erc20 liquidity pools or eth liquidity pools. To target only one of the two types in the tests, the --type flag can be set:

brownie test --type <POOL_TYPE`>

For example, to only target liquidity pools that hold an ERC20 token, run:

brownie test --type erc20

Testing Individual Pools

The Mero protocol has the following liquidity pools:

  • DAI
  • USDC
  • ETH

To target a specific pool, run:

brownie test --pool <NAME>

For instance, to run all tests for the DAI pool, run:

brownie test --pool dai

Each pool has a testconf.json configuration file (e.g. for DAI) in it's own directory located within the tests/configs directory. The config stores data such as:

  • underlying asset address
  • decimals of underlying asset
  • name of pool
  • symbol of pool LP token
  • strategy of the pool

This may be extended as the test suite is further developed.
