openQA Project (public)

Observation¶

Users create a needle that only has one item in area and its type is ocr.

links-connect-suse-webpage-20200411.json                                                                                                                     
 {
   "area": [
     {
       "xpos": 20,
       "ypos": 415,
       "width": 155,
       "height": 16,
       "type": "ocr"
     }
   ],
   "properties": [],
   "tags": [
     "links-connect-suse-webpage"
   ]
 }

Then openQA backend died when load this needle, the error message is

[2020-04-13T04:14:05.713 CEST] [debug] <<< testapi::assert_screen(mustmatch="links-connect-suse-webpage", timeout=30)
[2020-04-13T04:14:05.746 CEST] [debug] Backend process died, backend errors are reported below in the following lines:
Illegal division by zero at /usr/lib/perl5/vendor_perl/5.26.1/x86_64-linux-thread-multi/tinycv.pm line 49.

Failed job: https://openqa.nue.suse.com/tests/4114680/file/autoinst-log.txt

Open points¶

1. if the needle json file is valid?
2. if there is no `type: match` area in a needle json file, the backend should not died with this error message.

Suggestions¶

• Alternatives: Add caution hint in help text on the web page or catch single OCR and fail with error shown to user
