Answer 1

The class CreateQuotePDFController_Test contains no unit test methods. It contains only a test data setup method, data_setup(), which appears to also contain the start of a unit test but no assertions to validate behavior.

You need to write at least one actual unit test method. Please review How do I write an Apex unit test? for introductory resources. Every unit test should contain at least three elements:

• Data setup (which you've already done)
• Execution of functionality (which you've at least started to do, but in the wrong place)
• Assertions about behavior (which you need to add)
