Verify on HTTP::uri after mocking HTTP::uri

[Espenhh]

I'm using "on" to mock an incoming URI, and then my iRule changes this URI (removing a prefix) before sending it to the backend server. I want to test that the resulting URI is right, but this is a problem since I've already mocked out "HTTP::uri".

I've solved it by doing the verify on HTTP::path instead, but that feels like a hack. Any way to solve this?

Example iRule:

rule http {
    when HTTP_REQUEST {
        set newuri [string map {/api/ /} [HTTP::uri]]
        HTTP::uri $newuri
    }
}

Example test:

package require -exact testcl 1.0.2
namespace import ::testcl::*

# Comment in to enable logging
#log::lvSuppressLE info 0

it "should remove '/api' from URI" {
    event HTTP_REQUEST

    on HTTP::uri return "/api/users"

    ## This verify doesn't work:
    verify "result uri is '/users'" "/users" eq {HTTP::uri}

    ## This is the temporary solution I've used:
    verify "result path is '/users'" "/users" eq {HTTP::path}

    run rules/1.tcl http
}

in this case it will be easier to use:
HTTP::uri "/api/users"
instead of
on HTTP::uri return "/api/users"

"on" is fine if you need simple value substitution for whole irule statements, but if you need to verify if actual iRule logic is working it is better to use HTTP stub methods.

Thanks, that worked perfectly 👍
