# Automated Tests

Tests must have a well defined output, which is valid or not, and this will pass or fail the test.

{% hint style="info" %}
There must not be dependencies between tests, they must be able to be executed separately.
{% endhint %}

### Structure

A test can be separated in 3 steps.

#### Given (Arrange)

The definition of all necessary information to execute the behavior to be tested. *(Data input)*

#### **When (**Act)

Where you execute the behavior.

#### **Then (**Assert)

Where you compare the return information with the expected one. *(Basically is the* `expect`*)*

### Coverage

Coverage in tests means the amount of code that the tests run on. It is not related to `success` or `failure` percentage.
