Kamelet: Camel-Simple and Yaks do not interact well when using "Load Kamelet" in a Yaks test

[andy-d2019]

Given the following Syntax in a Kamelet running with Camel-K 2.1.0

 - set-property:
            name: data
            simple: "${body}"

If i use Kamelet load on the given Kamelet in a yaks test.feature file and run it with yaks run i get an exception of the form

org.citrusframework.exceptions.TestCaseFailedException: Unknown variable 'body'

Without Yaks the Kamelet runs perfectly fine by itself, but it seems like Yaks/Citrus try to interpret the variable in the simple-language block as their own variable.

I could find a workaround by escaping the dollar sign with '\u0024'. Other common yaml escape sequences do not seem to work.

Yes, this is because Citrus test variables and Camel simple language both use the same syntax '${}' for expressions.

You have two options here:

1. Set the option YAKS_CAMELK_SUPPORT_VARIABLES_IN_SOURCES to false - this will prevent Citrus from parsing the expressions in Camel K resources
2. Use the alternative simple language syntax $simple{ } in your Camel logic (e.g. $simple{body})

This should go into the YAKS documentation 😄

2. Use the alternative simple language syntax $simple{ } in your Camel logic (e.g. $simple{body})

Just to make sure, so this would be

set-property:
    name: data
    simple: "$simple{body}"

?

If yes, a PR for the docs would be my pleasure.

Thanks for the quick responses, this will make the Kamelet a lot more readable again 😄

Closing this one as it seems to have clarified. Thx!
