Module:Params/testcases/tmulti sandbox
This test template allows to simulate in one single call both the incoming parameters and the parameters possibly concatenated to {{#invoke:params|...|function|...}}, using a single hyphen (-) as a delimiter between the two groups. This allows to make general experiments directly from the preview window without having to edit separate templates.
Warning Please be aware that there are numerous limitations on what can be experimented using this template. In case of errors, please use a sandbox template.

{{module:params/testcases/tmulti sandbox|
