class DeveloperTest extends TestCase {
    /**

If you don’t know where to start, this is a very good starting point. </p>

Two points to emphasize:

• Tests give you confident to change code. (Laracasts)
• The value of tests get higher as time goes on.

Usually my workflow is this:

• How the feature is reached?
• What is expected to come out?

That’s pretty much it. Write test first, not after. It helps me clarify the problem and write a better solution.
