jq assignment where the path contain space - windows

Question

This might be a simple question but I am struggling to figure out how jq work with spaces in elements. (The following is in windows powershell)
PS C:\Users\Home> "{}" | jq ".mytest.path = """"success"""""
{
"mytest": {
"path": "success"
}
}
Now, I want to make "my test" two separate words. My desired output is
{
"my - test": {
"path": "success"
}
}
What query would I used? I tried the following:
PS C:\Users\Home> "{}" | jq ".""my - test"".path = """"success"""""
jq : jq: error: Could not open file test.path = "success": Invalid argument
At line:1 char:8
+ "{}" | jq ".""my - test"".path = """"success"""""
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (jq: error: Coul...nvalid argument:String) [], RemoteException
+ FullyQualifiedErrorId : NativeCommandError
PS C:\Users\Home> "{}" | jq --raw-output ".""my test"".path = """"success"""""
jq : jq: error: Could not open file test.path = "success": Invalid argument
At line:1 char:8
+ "{}" | jq --raw-output ".""my test"".path = """"success"""""
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (jq: error: Coul...nvalid argument:String) [], RemoteException
+ FullyQualifiedErrorId : NativeCommandError
Any suggestions?

First, setting aside for the moment all the issues related to peculiarities of different shells, the jq filter you need is:
.["my test"].path = "success"
(If ever in doubt about using the .foo syntax, you can always fall back on the fundamental form: .["key name"].)
Since you are evidently conversant with the transmogrification required by the mighty PowerShell, I'll just point out here that one can simply place the jq program in a file (say program.jq) and invoke jq with the -f option (jq -f program.jq ...).
