Adding an assert to a schema object
Add asserts to a DFDL schema object to define tests to ensure that data in the message are well-formed.
Before you start:
Create or open a DFDL schema file. See DFDL schema editor for a description of the DFDL schema editor.- In the Editor view, select the DFDL schema object on which you want to add an assert.
- On the Asserts and Discriminators tab of the DFDL Properties area, select Asserts, then click Add assert. If a discriminator is already applied to the object, the Asserts option is disabled, as an object cannot have both an assert and a discriminator applied to it.
- Enter your test expression in the Test Condition field, and a human-readable failure message in the Message field. Content assistance is available for the Test Condition field; press Ctrl+Space to open the XPath Expression Builder.
Your assert is used when the message model is run.
