.SYNOPSIS
|
||
|
|
Regression tests for install.ps1.
|
||
|
|
|
||
|
|
.BUG
|
||
|
|
`irm <url> | iex` closed the terminal window. Cause: the script used
|
||
|
|
`exit`, which under Invoke-Expression terminates the entire PowerShell
|
||
|
|
host process (there is no script scope to exit). Fix: use `return`
|
||
|
|
(success) / `throw` (errors) so the host survives.
|
||
|
|
|
||
|
|
.NOTES
|
||
|
|
Host-process termination cannot be observed from inside the dying process,
|
||
|
|
so these tests combine a source-verification guard with a behavioral test
|
||
|
|
run in a child process (`exit` cannot be caught by try/catch and kills the
|
||
|
|
child; `throw` is catchable).
