# countWordOccurrences

> Checks whether the word "test" appears at least once in the given string (case-insensitive).

## Input

* **`input`**: The original input text or data
* **`output`**: The input string to check for occurrences
* **`expectedOutput`**: The expected output to compare against.

<Note>
  - Any of the input variables (`input`, `output`, `expectedOutput`) can be marked as optional.
  - The returned value from the `validate` function can be a boolean, string, or a number.
</Note>

## Output

* **`Result`**: Boolean (`true` or `false`) | string | number

## Interpretation

> Assuming this evaluator returns a boolean

* **true**: The word appears at least once
* **false**: The word does not appear

<Note>This evaluator requires a function named <code>validate</code>.</Note>

## Example

```javascript theme={null}
validate("Test this string") // returns true
validate("No matches here") // returns false
```
