# Like test

Learn how to check if a string includes another substring.

This test checks if one string is equal to another string or contains it.

The test is case-insensitive, meaning that the strings match regardless of capitalization. For example, `"Hello world"` is like `"Hello"` and `"hello"`.

## Syntax

This test has the following syntax:

```cql
/*<value>*/ is like /*<term>*/
```

To negate the test, you can write:

```cql
/*<value>*/ is not like /*<term>*/
```

## Parameters

These are the supported parameters:

- `value`: `string`

  The string to validate.

- `term`: `string`

  A term to check if the string includes.

## Examples

Here is a basic example that checks if a string is like another string:

```cql
"Hello world" is like "hello" // true
```

You can negate the test to verify the contrary:

```cql
"Hello world" is not like "hello" // false
```
