This assertion is used to check if the element value described by the expression matches a knowledge base of some kind. For example a US Zipcode or a US State. This also gives you the ability to write your own regex (regular expression).
Parameters:
| Name | Type/Value | Required |
|---|---|---|
| Expression | Expression | Yes |
| Type | ‘regex’ or ‘US Zipcode’ or ‘US State’ or ‘credit card’ or ‘country codes’ or ‘currency codes’ | Yes |
| Regex value | String | Yes, if type is ‘regex’ |
| Mode | ‘all’ or ‘one’ | No |
| Level | ‘error’ or ‘warning’ | No |
| Modifier | ‘not’ | No |
| Execute if item exists | ‘true’ or ‘false’ | No |
| Stop test if fails | ‘true’ or ‘false’ | No |
| Comment | String | No |
Expression: It’s the path to the element we want to operate on (ex: payload.ProductID). See Expression for more details.
Type: The data type of the value. The possible values are: ‘regex’, if you want to evaluate the field as a regular expression (specified in regex value); ‘US Zipcode’, checks if the field is a valid US Zipcode; ‘US State’, checks if the field is a valid US State (i.e. ‘NY’); ‘credit card’; checks if the field contains a valid credit card number from the most popular credit cards (i.e. VISA, Mastercard, AMEX); ‘country codes’, checks if the field contains a valid country code (i.e. ‘US’, ‘FR’, ‘DK’); ‘currency codes’, checks if the fields is a valid currency (i.e. ‘USD’, ‘EUR’)
Regex value: Specify the regular expression you want to use for checking the expression.
Mode: Specify if all the same elements in the payload should match the assertion (‘all’) or if only one element (‘one’) is enough.
Level: Specify if the assertion fails whether it should be considered an ‘error’ or just a ‘warning.’ A warning will not trigger alerts (such as email or text messages).
Modifier: The assertion is considered verified if it does not pass.
Execute if item exists: The assertion is evaluated only if the element exists. This is useful when the element does not always exist.
Stop test if fails: The test will be immediately stopped if the assertion fails.
