Generate test File
------------------

This create a new solidity file in the current folder suffixed with `_test`.
This file contains the minimun you need for running unit testing.

Run Tests
---------

This executes all tests whose box has been checked below (by default all). The execution is run in a separate environment and the result is displayed below.

Here is a list of functions and their supported types that you can use to write your testcases:

| Available functions  | Supported types |

| ------------- | ------------- |

| `Assert.ok()`  | `bool`  |

| `Assert.equal()`  | `uint`, `int`, `bool`, `address`, `bytes32`, `string`  |

| `Assert.notEqual()` | `uint`, `int`, `bool`, `address`, `bytes32`, `string`  |

| `Assert.greaterThan()` | `uint`, `int` |

| `Assert.lesserThan()` | `uint`, `int` |
