Assignment Aim

The aim of the assignment is to assess your ability to produce test cases and test data that can be traced back to a given set of requirements.

Background to case

St Michael’s College in Auckland offers a job search facility for its students. An increasing number of employers are using the services offered by St Michael’s Job Search and a new database application is required to help the automation of the processes of tracking employers’ vacancies and students’ details. The main goal of the application is to provide a robust system so that employers are presented with accurate student information and students are guided towards appropriate vacancies.

Scenario

You have been hired as a test analyst for St. Michael’s. You have been allocated the task of producing a set of test cases (with associated test data) that is to be used to test the St Michael’s Job Search database application.

Instructions

You are to complete a testing report for the St. Michael’s case study. You will find, on Moodle, a test cases template that you can use. This assignment is an individual assignment. Although the application consists of 11 processes you only need to produce test plans (test cases, test data and justifications) for any 2 processes that make up a test package. Test packages are allocated to you by the test manager (lecturer).

You are required to produce a testing report that will contain:

  • A title page
  • A table of contents
  • An introduction
  • Test plans for two processes
    • Loaded test data
    • Test cases
    • Justification of test cases (traces tests back to business rules, data dictionary and data volume requirements)

Notes

  • Remember that one individual test case may involve several steps that can be dependent on each other.
  • Remember to verify the expected results of the tests with other tests if possible. For example, if you have a test that adds a new record, then use the ‘view’ facility in the program to check that the record has been added.
  • Comprehensive testing of valid and invalid data needs to be done for adding new records. However, for modifying existing records you only need to test each field twice: once with valid data and once with invalid data. You should also have test that modifies all allowable fields with valid data.
  • If more than one field has invalid or missing data then an error message should be displayed for each field that has invalid or missing data.
  • The loaded test data must reflect the cardinality of the database. For example: There is an optional ‘one-to-many’ relationship between Employer and Vacancy which means that you must have at least one employer with no vacancies, at least one employer with many vacancies and at least one employer with just one vacancy.
  • Select your input test data to make your tests as independent as possible. For example: if you are testing that a program deletes an employer record then use, as test data, an employer that exists in the loaded test data NOT an employer that was input in an earlier test.
  • Remember to check for missing or ambiguous business rules and seek clarification with the test manager (lecturer) if necessary.

Business Rules

The business rules may be incomplete – carry out the checks discussed in class and ask questions (via email) if you feel you require clarification.
