Assert Matches

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).


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.

Comment: It’s a string value where you can write a note.
