`remix-tests` is a tool to test Solidity smart contracts. It works underneath Remix IDE plugin "Solidity Unit Testing" which is used to write and run test cases for a contract. Tests are written in Solidity itself. `remix-tests` can be used as CLI and a library too.
To know more about Remix IDE `Solidity Unit Testing Plugin`, visit [Remix IDE official documentation](https://remix-ide.readthedocs.io/en/latest/unittesting.html).
### Installation

To confirm installation, run:
```

Example to understand the use of special methods can be found [here in tests](tests/various_sender/sender_and_value_test.sol).
#### Use a different sender `msg.sender`
It is quite common that a contract need to be tested in different situation.
Especially being able to set before hand the sender account (`msg.sender`) used for a specific tests suite enable quite a lot a new test use cases.
please checkout this [test contract](https://github.com/ethereum/remix/blob/master/remix-tests/tests/various_sender/sender_test.sol) for an example.
please checkout this [test contract](tests/various_sender/sender_and_value_test.sol) for an example.
Note that `TestsAccounts` is filled with all the accounts available in `web3.eth.accounts()`.
### How to use
