testRunner results not coherent

Hello,

I encounter a problem with testRunner results.

I have a testCase with 15 steps, in the teardown script I list the result for each testStep with the following code:

for (testStep in testRunner.getResults()){
  log.info "step " + testStep.getTestStep().getName() + " : " + testStep.getStatus()
}

As a result I get information for the five last steps only. If I monitor testRunner.getResultCount() I get 47

log.info testRunner.getResultCount()
log.info "nb steps : " + testRunner.getTestCase().getTestStepCount()

if I monitor the number of steps in the testCase, I get 15

This snippet used to work properly for some other testCases.

Any idea ?  :(
