Description |
Up to yesterday we used 3.0.x version. We have configured a lot of Web-Monitoring scenarios. Up to now we used a macro for domain configuration: {domain}=http://www.myshop.com and in the Steps we used that macro for the URLs: {domain}/firstpage.html {domain}/secondpage.html and so on ... So now after the update to 3.2.1 all Web-Monintoring scenarios do not work any longer. Error message is: "Step "Startpage" [1 of 4] failed: Couldn't resolve host name: Could not resolve host: {domain}" So it looks as if the macro is not recognized any longer. I did replace the macro in the steps with the real domain name - and then it works. But as we do have up to hundred and more of such checks I would be thankful if I would not have to change alle the steps manually ... :-o Can you help? |

Why do we process regexes on scenario level in the first place? If we'd ignore them it would allow the following use case:
This also currently doesn't work:
wiper We don't support variable substitution in variable definitions. So it would't work anyway. <dimir> Yes, I understand, just an idea here. |
