Validation Module in MuleSoft

The Validation Component in MuleSoft is used to verify a message in a Mule flow. If a message does not meet the specific criteria, the validation fails and returns a validation error.

Validation Components in Mule are shown below:

Now, I will demonstrate validation using a few of the components from the image above.

All Scope: executes all validators and requires that all validations pass in order for the flow to execute. If one validation fails, the remaining validators are still executed.

Is number: verifies that a string can be parsed as a number of a specified numeric type.

Is empty collection: validates that a value is in collection or not.

Is email: checks if a given email is valid or not.

Is not blank string: validates that the provided value is not a blank string.

Matches regex : validates that a given expression matches a regular expression.

Is null: validates if the provided value is null.

Here is the expected output:
