The Complete Task

Introduction

Objectives

This guide  will help you to: -  

·   produce test plans you can use for testing your program

You should print out the following two assignment documents.

Assignment Scenario

Assignment 2: Designing the Program

An important stage in design is to create a test plan which you can follow when the program is implemented.  It is vital that the program gives the correct results and so you use a test plan to check if it works properly.  

In order to complete Assignment 2 Task d, you need to produce a record of how you will test the program using the data provided and using data that you have created.

Lets look at the data provided...

Data Provided:

Lawn 1: Lawn 1 is a rectangle measuring 18 metres by 12 metres.   Lawn 2: Lawn 2 is a circle with a diameter of 16 metres. The radius is half the diameter.    Field 1: The big rectangle measures 120 metres by 100 metres, and the small rectangle (the bit missing) measures 55 metres by 50 metres.   Field 2: The field is 100 metres by 75 metres and the pond has a diameter of 25 metres. The radius is half the diameter.   Stored Data: For lawn seed, 30 grams of seed covers one square metre of lawn For hay meadow seed, 20 grams of seed covers one square metre of lawn Lawn seed is purchased in 1 kilogram bags Hay meadow seed is purchased in 5 kilogram bags

We can produce a test table with a column of expected results calculated manually.  We would also create an empty column - ready to be filled in when we test the program with actual results. 

Have a look at my example below. (I have only included the lawn calculations - you have to include the hay meadow calculations.)

Test No.	Dimensions	Calculation	Expected Result	Actual Result	Comment
Area Calculations
1	Length = 12m Width = 18m	Area of Rectangular Lawn	216m2
2	Radius = 8m	Area of Circular Lawn	201m2
Seed Amount Calculations
5	Total Area = 417m2	Amount of Lawn Seed	12510 g
Number of Bags Calculations
6	Amount of seed needed = 12510g	Number of Bags of Lawn Seed	12.5 bags

~~Activity~~

Task d: part 2 - Produce test plans using your own data

Now you have produced a test plan using the data provides, you need to create another test plan using your own data.  This means you have to make up your own lengths, widths etc. for the different lawn and field shapes.  You will have to calculate the areas, amount of seeds and number of bags using your chosen lengths/widths.

Have a look at my example below. (I have made up different dimensions for the lawns. You need to make up your own measurements.)

Test No.	Dimensions	Calculation	Expected Result	Actual Result	Comment
Area Calculations
1	Length = 10m Width = 15m	Area of Rectangular Lawn	150m2
2	Radius = 5m	Area of Circular Lawn	79m2
Seed Amount Calculations
5	Total Area = 229m2	Amount of Lawn Seed	6870 g
Number of Bags Calculations
6	Amount of seed needed = 6870g	Number of Bags of Lawn Seed	6.9 bags

The Complete Task

Your Task

The complete task comprises the tables you have produced for Activity A and Activity B.

Please ensure you write your name in the document header. The structure of your document should be as follows:-

Assignment 2: Designing the Program

      Task d: part 1 - Test plan using data I have been given

Here you should include your first test table from activity A.

      Task d: part 2 - Test plan using my own data

Here you should include your first test table from activity B.

Have you finished all the tasks and handed them in?  

If so - well done.
