Claus Ibsen commented on CAMEL-772:
-----------------------------------
I have attached a patch with this change. However as it's a bit magical that
Camel will type convert to the right value (usually the data type on the
exchange/message) before performing the matching.
But you can do:
{code}
mock.message(0).body().contains("<patientCpr>0101701234</patientCpr>");
{code}
And it will convert the string to byte[] as the body() is a byte[]
You can still do the convertBodyTo as well:
{code}
mock.message(0).convertBodyTo(String.class).contains("<patientCpr>0101701234</patientCpr>");
{code}
> Predicates with two types should consider casting to desired type before
> evaluating

> Project: Apache Camel
> Issue Type: Improvement

> Affects Versions: 1.4.0
> Reporter: Claus Ibsen

> I had this unit test where I want to assert that the message body contains
> this string part
> {code}
> MockEndpoint error = getMockEndpoint("mock:errorQueue");
> error.expectedMessageCount(1);
>
> error.message(0).body().contains("<patientCpr>0101701234</patientCpr>");
> {code}
> But the expression fails because the body is byte array and is not casted to
> String as the contains type is.
> If I change the code to:
> {code}
>
> error.message(0).body().convertTo(String.class).contains("<patientCpr>0101701234</patientCpr>");
> {code}
> Then it of course works. But what if there already is a type convert in Camel
> that could have done the cast for me?
> But is it dangerous to add such automatic type casting behind the end-users
> back? Any thoughts?
