A fallback for when tree-kill fails

[sagar2427]

i down loaded example code from stryker.io , and i am start doing steps given ,to get the reports but whenever i am doing npm run stryker , i am getting error like above

[nicojs]

Ah yes. Couple of work arounds:

1. Install git and run git init in D:\robobar-example-master.
2. Install git and create a fresh clone: git clone https://github.com/stryker-mutator/robobar-example.git and use that instead.
3. Configure files inside the stryker.conf.json. You can use "files": ["**/*", "!node_modules/**/*"]

Did you install the dependencies?

npm install

[nicojs]

Ah, could you try to run taskkill /?, does that print the help for the taskkill command?

[sagar2427]

yup,
i did npm install for dependencies and i killed all the PIDs available in the task manager.
even i installed stryker global npm install -g stryker-cli

but still i am getting same issue :(

Hmm ok, so you are running on windows, yet taskkill isn't available. Could you verify this by running taskkill /??

Could you please provide more information about your system. What windows version are you running?

Taskkill should be installed on almost every windows version: https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/taskkill

[sagar2427]

when ever i am running taskkill command its showing like

D:\robobar-example-master>taskkill
'taskkill' is not recognized as an internal or external command,
operable program or batch file.

D:\robobar-example-master>taskkill /?
'taskkill' is not recognized as an internal or external command,
operable program or batch file.

windows version -- windows 10 pro
64 bit OS, x65-based process

[nicojs]

For me, taskkill.exe lives in C:\windows\system32. Could you try to have a look there? If it's there, you might need to add C:\windows\system32 to your PATH environment.

[nicojs]

I've also opened pkrumins/node-tree-kill#34

[sagar2427]

Thanks @nicojs , after adding PATH environment , now able to run with out errors and i am getting coverage report also.

[nicojs]

Great! I've renamed the issue, we should implement a fallback for when tree-kill fails (maybe just use process.kill?).

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

[nicojs]

See #4577 for an example where a linux pipeline fails because of tree-kill. I think we should implement a fallback to normal childProcess.kill when tree-kill fails.

Hi @nicojs,

I got the same error.

I already added C:\windows\system32 to my PATH variable and can use taskkill /?:

> taskkill /?

TASKKILL [/S System [/U Benutzername [/P [Kennwort]]]]
         { [/FI Filter] [/PID Prozess-ID | /IM Abbildname] } [/T] [/F]

...

However, now I run into another Error, which might be related?

}

From the debug output it seems, this is the CheckerWorker he tries to kill

Any ideas?
