Matches test
Learn how to check if a string matches a regular expression.
This test checks if a string includes another string or matches a regular expression.
When matching a string, the test checks if the string includes the other string. For example, "Hello world" matches "lo wo". The test is case-sensitive, meaning that the strings must match exactly, including the case of the letters.
You can use the i flag to match case insensitively using regular expressions.
Syntax
This test has the following syntax:
/*<value>*/ matches /*<pattern>*/
To negate the test, you can write:
/*<value>*/ does not match /*<pattern>*/
Parameters
These are the supported parameters:
- value
The string to validate.
- pattern
A string or regular expression to check if the string matches.
Examples
Here is a basic example that checks if a string matches another string:
"Hello world" matches "lo wo" // true
You can negate the test to verify the contrary:
"Hello world" does not match "lo wo" // false
You can also use a regular expression to match a string:
"CQL is powerful" matches ~/^[a-z]{3}/i // true
In this example, the test checks whether the string starts with three letters. The i flag makes the test case-insensitive.
