A Gatling scenario with an exec chain. After a request, returned data is saved. Later it's processed and depending on the processing result, it should either fail or pass the test.
This seems like the simplest possible scenario, yet I can't find any reliable info how to fail a test from within an exec block. assert breaks the scenario and seemingly Gatling (as in: the exception throw doesn't just fail the test).
Example:
// The scenario consists of a single test with two exec creating the execChain
val scn = scenario("MyAwesomeScenario").exec(reportableTest(
// Send the request
exec(http("127.0.0.1/Request").get(requestUrl).check(status.is(200)).check(bodyString.saveAs("MyData")
// Process the data
.exec(session => {
assert(processData(session.attributes("MyData")) == true, "Invalid data");
})
))
Above the scenario somewhere along the line "guardian failed, shutting down system".
Now this seems a useful, often-used thing to do - I'm possibly missing something simple. How to do it?
You have to abide by Gatling APIs.
processData
in the check, typically in the transform optional step.were you looking for something like
.exec(http("getRequest")
.get("/request/123")
.headers(headers)
.check(status.is(200))
.check(jsonPath("$.request_id").is("123")))
Since the edit queue is already full.
This is already resolved in the new version of Gatling. Release 3.4.0
They added
exitHereIf("${myBoolean}")
exitHereIf(session => true)
Make the user exit the scenario from this point if the condition holds. Condition parameter is an Expression[Boolean].
I implemented something using exitHereIfFailed
that sounds like exactly what you were trying to accomplish. I normally use this after a virtual user attempts to sign in.
exitHereIfFailed
is used this way
val scn = scenario("MyAwesomeScenario")
.exec(http("Get data from endpoint 1")
.get(request1Url)
.check(status.is(200))
.check(bodyString.saveAs("MyData"))
.check(processData(session.attributes("MyData")).is(true)))
.exitHereIfFailed // If we weren't able to get the data, don't continue
.exec(http("Send the data to endpoint 2")
.post(request2Url)
.body(StringBody("${MyData}"))
This scenario will abort gracefully at exitHereIfFailed
if any of the checks prior to exitHereIfFailed
have failed.
