# Suites: Describe Your Tests

A test suite in TestBox is a collection of specifications that model what you want to test. As we will investigate, the way the suite is expressed can be of many different types.

> Test suite is a container that has a set of tests which helps testers in executing and reporting the test execution status.

A test suite begins with a call to our TestBox `describe()` function with at least two arguments: a `title` and a `body` function/closure. The `title` is the name of the suite to register and the `body` function/closure is the block of code that implements the suite.

When applying BDD to your tests, this function is used to describe your story scenarios that you will implement.

```javascript
function run( testResults, testBox ){

     describe("A suite", function(){
          it("contains spec with an awesome expectation", function(){
               expect( true ).toBeTrue();
          });
          it("contains spec with a failure expectation", function(){
               expect( true ).toBeFalse();
          });
     });

}
```

The `describe()` function is also aliased with the following names:`story(), feature(), scenario(), given(), when()`
{% endhint %}

## Arguments

There are more arguments, which you can see below:
