ModifiablePayload
Trait implemented by PayloadField
exception types that can modify their payload.
This trait facilitates the withPayload
construct provided by trait
Payloads
. This construct enables a payload object (or modified
payload object) to be included as the payload of a thrown exception. The payload
can then be included in the ScalaTest event that results from that exception. For
example, the payload included in a TestFailedException
will be included
as the payload of the resulting TestFailed
event. Here's an example in
which a GUI snapshot is included as a payload when a test fails:
withPayload(generateGUISnapshot()) { 1 + 1 should === (3) }
Exception types that mix in this trait have a modifyPayload
method, which
returns an exception identical to itself, except with the payload option replaced with
the result of invoking the passed function, supplying the current payload option
as the lone Option[Any]
parameter.
Value members
Abstract methods
Returns an instance of this exception's class, identical to this exception,
except with the payload option replaced with
the result of invoking the passed function, fun
, supplying the current payload option
as the lone Option[Any]
parameter.
Returns an instance of this exception's class, identical to this exception,
except with the payload option replaced with
the result of invoking the passed function, fun
, supplying the current payload option
as the lone Option[Any]
parameter.
Implementations of this method may either mutate this exception or return a new instance with the revised detail message.
- Value parameters:
- fun
A function that returns the new payload option given the old one
