Most test(n) templates take a single optional parameter: the name of the page to which the template applies. If provided, this page will be cited in the warning.
test5 optionally takes two parameters:
The first is the duration of the block (with "temporarily blocked" as the default if a specific period is not provided).
The second is the name of the page to which the template applies. If provided, this page will be cited in the warning.
Please refer to the index of test templates before using any template on user talk pages to warn a user. Applying the best template available for your purpose may help reduce confusion from the message you are sending.
Please remember to substitute the template—use {{subst:TestTemplatesNotice}} rather than {{TestTemplatesNotice}}.
