Your first test class

Your first class and test

Anonymous Apex is great for experimenting, but real code lives in classes. And Salesforce won't let you deploy to production unless your tests cover at least 75% of your code.

public with sharing class Greeter {
    public static String greet(String name) {
        return 'Hello, ' + name + '!';
    }
}

A test class looks like this:

@isTest
private class GreeterTest {
    @isTest
    static void greetsByName() {
        Assert.areEqual('Hello, Quill!', Greeter.greet('Quill'));
    }
}

Your mission

Create these in your org, using the Developer Console (File → New → Apex Class), VS Code or sf project deploy start:

1. AQ_Greeter with public static String greet(String name)
   • greet('Quill') returns 'Hello, Quill!'
   • a blank name returns 'Hello, mysterious Trailblazer!' (use String.isBlank)
2. AQ_GreeterTest, which passes and covers ≥ 75% of AQ_Greeter

Then hit Submit. Quill will call your method and run your tests in your org.

🦝 Test both branches and you'll hit 100%. Quill notices these things.
