Software Development 2 Assignment Two

Assignment Title – SD2 Worksheet Two: Unit Tests and version control

Assignment Instructions

This worksheet is to help you become familiar with the basics of

• Writing unit tests
• Test Driven Development with Git

This worksheet is worth 6% of your CA

Submit before 25/02/26 23:59

Create a new project in Eclipse(or other IDE) called SD2_LabTwo_<studentnumber> • With <studentnumber> being your student number i.e.   SD2_LabTwo_323212.

For this exercise you will need to set up a GitLab or GitHub repository and share it with your lecturer as a Developer. Make sure to grant your lecturer developer level access to the repository.

After writing each unit test and before writing the implementation you will need to make a commit. It is an absolute requirement of the worksheet that you commit after each completion of a unit test and implementation. You will lose marks if your repository does not reflect this.

Task 

• Create two files “ConversionsTest.java” and “Conversions.java” and commit them to the repository.
• In Conversions.java add method stubs and only the stubs for the methods below, once you have written all stubs commit them to the repository. Do not implement the methods until after the tests are written.
• • public double euroToDollar(double euro) o public double dollarToEuro(double dollar) o public int stringToInteger (String val) o public String integerToString (int val)
  • public String switchCase() // change uppercase to lowercase and vice versa
  • Include screenshots of the method stubs below

• In ConversionsTest.java add Unit tests for each method. o Each unit test must perform at least three tests on the method involved.
  • Test different ranges (positive, negative, null values, etc..) o Write them one at a time as you will need to commit after writing each
  • For each individual unit test, after writing the tests, run it and it should fail, then commit it to the repository.
  • In Conversions.java implement the appropriate method so it will pass the unit test, once it succeeds commit it to the repository.
  • do not move onto the next test until the previous one has succeeded and has been committed.
  • Continue until all tests have been completed.
  • For each unit test include screenshots below of
    • the unit test
    • the tests failing
    • the method implementation
    • the tests succeeding

Marks

o Unit tests (25 marks)
o Implementation (25 marks)
o Comments and Coding Standards (10 marks)
o Repository with proper commit history (40 marks)

Comments and Coding Standards

Comments

• Include a comment at the top of the file with your name and student number.

Add a comment for each coding task explaining what the code does.

Follow coding standards: 

• Lowercase for variable names.
• Uppercase for the class name.
• All uppercase for constants.
• Use naming standards.
• Indent your code.

Zip the whole project folder and upload your folder on Moodle as SD2_LabTwo_StudentNumber.zip.

Note that it is an absolute requirement of the worksheet that you commit after each completion of a unit test and implementation. You will lose marks if your repository does not reflect this.
