I want to know if I can open an lightning component through a button on a visualforce page.
Each button corresponds to a different component that I want to pop up I was wondering if I could write javascript to do this. If so what would that look like? I've never written javascript before.

<--- Visual Force Page --->
<apex:page standardController="Leverage__c">
    <apex:form >
        <h1>
            Support Services

Built a trigger that limits the number of a certain type of Lead a User can have trying to Test it. I have four methods that test four different Users that have four differnt caps 100, 200, 300, and 400. The 200 and the 400 Methods work, but the 100 and 300 don't work. They are all the exact same method and user. I have tried switching the users and that doesn't work, but if I change the caps then it works. The error I'm getting is Assertion Failed

Wrote a trigger that caps how many of a certain type of lead that a user can have need help writing the test class

TestFullCapStatus and TestFullCapType are woriking properly, but the rest aren't and I don't understand why?
TestFullCapTrue shouldn't allow any of the leads to update and the others should allow all the leads under their respective caps to change and reject the rest. Each List<Lead> has 500 so for example TestCap100True should allow the first 100 to change leadOwner, but not the next 400.

Wrote a trigger to limit the amount of leads a specific owner can have. Trying to write the test class for the trigger and am getting this error:

I am trying to get a picture to show up based on a condition the problem is that I know this condition to be true, but it is giving the False output.
