I\'m using Karate framework with JUnit.
Using this feature:
Given path \'save_token\'
And request
\"\"\"
{
\"token\": \"test_token\"
}
\"\"\"
And r
The retry until expression has to be pure JavaScript and the special Karate match keywords such as contains
are not supported, and you can't do a "deep equals" like how you are trying, as that also is not possible in JS.
EDIT: in 0.9.6. onwards you can do a complex match
in JS: https://stackoverflow.com/a/50350442/143475
Also note that JsonPath is not supported, which means *
or ..
cannot appear in the expression.
So if your response is { "tokens": [ "value1" ] }
, you can do this:
And retry until response.tokens.contains('value1')
Or:
And retry until response.tokens[0] == 'value1'
To experiment, you can try expressions like this:
* def response = { "tokens": [ "value1" ] }
* assert response.tokens.contains('value1')
At run time, you can use JS to take care of conditions when the response is not yet ready while polling:
And retry until response.tokens && response.tokens.length
EDIT: actually a more elegant way to do the above is shown below, because karate.get()
gracefully handles a JS or JsonPath evaluation failure and returns null
:
And retry until karate.get('response.tokens.length')
Or if you are dealing with XML, you can use the karate.xmlPath()
API:
And retry until karate.xmlPath(response, '//result') == 5
And if you really want to use the power of Karate's match
syntax, you can use the JS API:
And retry until karate.match(response, { tokens: '##[_ > 0]' }).pass
Note that if you have more complex logic, you can always wrap it into a re-usable function:
* def isValid = function(x){ return karate.match(x, { tokens: '##[_ > 0]' }).pass }
# ...
And retry until isValid(response)
Finally if none of the above works, you can always switch to a custom polling routine: polling.feature
EDIT: also see this answer for an example of how to use karate.filter()
instead of JsonPath: https://stackoverflow.com/a/60537602/143475
EDIT: in version 0.9.6 onwards, Karate can do a match
in JS, which can simplify some of the above: https://stackoverflow.com/a/50350442/143475
