public NotThrownAssert describedAs(Description description)

Implements org.assertj.core.api.Descriptable.describedAs.

Doc from org.assertj.core.api.Descriptable.describedAs.

Sets the description of the assertion that is going to be called after.

You must set it before calling the assertion otherwise it is ignored as the failing assertion breaks the chained call by throwing an AssertionError.

This overloaded version of "describedAs" offers more flexibility than the one taking a String by allowing users to pass their own implementation of a description. For example, a description that creates its value lazily, only when an assertion failure occurs.

Parameters
description:Description

the new description to set.

Returns:NotThrownAssert

this object.
