Function: In a package named "lecture" create an object named "FirstObject" with a method named "computeShipping Cost" that takes a Double representing the weight of a package as a parameter and returns a Double representing the shipping cost of the package The shipping cost is ($)5 +0.25 for each pound over 30 Unit Testing: In a package named "tests' create a class/file named "UnitTesting" as a test suite that tests the computeShipping Cost method def computeShippingCost(weight: Double): Double - if (weight <3.0) 5.0 } else { 5.0 (Math. round(weight) - 30.0) +0.25 rounding_weight def computeShipping Cost (weight: Double): Double - 5.0 + (weight - 30.0) +0.25 always_over_thirty def computeShipping Cost (weight: Double): Double if (weight < 33.0) { 5.0 } else { 5.0 + (weight - 33.0) - 0.25 boundary overweight def computeShipping Cost (weight: Double): Double = { if (weight < 30.0) { light_employee_discount } else { 5.0 + (weight - 30.0) - 0.25 def computeShipping Cost (weight: Double): Double - { 5.0 always_under_thirty
