the allure-results folder zips to 47mb so not sure how to send to you?

Do I need to raise this on an allure specific project instead of allure npm wrapper?

[just-boris]

Stacktrace is the same as webdriverio-boneyard/wdio-allure-reporter#26
Do you use Cucumber?

[simonwilbert]

Hi, yes, Cucumber is used. So short-term fix is for us to maybe hack the allure-results' json files or medium-term solution is to wait for next release containing that stale PR?

[simonwilbert]

For now we're using work-around on string-replace json files

status="" to status="broken"
stop="" to stop="1488360005476" where 1488360005476 is controlled number

[just-boris]

This is not a solution because then your report will become not true.
As I mentioned in the above ticket, the problem is that for some reason (possibly, when test fails), cucumber doesn't provide enough data for Allure.

The current version of Allure 1.5.x requires test times as required values, so report can't be built without them. Maybe we could make a more user-friendly error message, but instead, we are working on Allure v2, that will not have this problem.

[GeoffreyBooth]

In case it helps anyone else, here’s my implementation of @simonwilbert’s workaround:

# If the Allure test results folder has files, generate a report from those files
if [ "$(ls -A ./allure-report)" ]; then
  # Monkey-patch workaround for https://github.com/allure-framework/allure-npm/issues/6#issuecomment-283311586
  # Replacement code via http://stackoverflow.com/a/19457213/223225
  LC_ALL=C # http://stackoverflow.com/a/23584470/223225
  find ./allure-report -type f -print0 | xargs -0 sed -i '' -e 's/status=""/status="broken"/g'
  find ./allure-report -type f -print0 | xargs -0 sed -i '' -e "s/stop=\"\"/stop=\"$(date +%s)000\"/g"

  allure generate ./allure-report
fi

@just-boris If you aren't going to fix this problem in v1, how soon can we get access to v2? I am able to get results when I run single specs, but not when I run my entire suite, even though the suite passes and has no timeouts.

Also, is it possible for allure to show a history of test results, or does it only present the most recent set of results?

[just-boris]

Redirecting the last question to @baev

[baev]

history is only available when using Jenkins plugin (v2.13+) and latest Allure commandline (2.0-BETA5). It is fully backward compatible with old adapters

[tiffanywilson]

Thanks for the quick responses @just-boris and @baev.

But what about v2 and the errors Exception in thread "main" java.lang.NumberFormatException: For input string: ""?

[just-boris]

Allure 2.0 is already released and published. Please, check
