Trigger events manually?

[Niightblade]

Is is possible to trigger an event manually for testing purposes?

Not literally, however you could always do something like

local f = CreateFrame("FRAME");
f:RegisterEvent("CHAT_MSG_ADDON");
f:SetScript("OnEvent", function(self, event, ...)
   if event == "CHAT_MSG_ADDON" then
      -- Handling code here
   end
end);

f:GetScript("OnEvent")(f, "CHAT_MSG_ADDON", --[[ All the params here ]]);

Hmm ok thanks for that. I don't suppose you have an example of the args that are parsed when SPELL_DISPEL_FAILED is triggered do you? Very hard to test something that fails so rarely

I know there are a few events that are fired from an API function, but not all of them. The only API function I know that fires a couple of events is UpdateSpells(), and those events are probably not what you want.

Although, I do have a suggestion for it. Have a saved variable that is specifically for specialize debugging. Every time the event occurs, add the parameter list to the saved variable. From there, you have test parameters to play with the function. I did something similar that was saving the list of keys in _G that are functions.
