CHC6072: Software Analysis and Testing

(Semester 1, 2023-2024)

Coursework Specification

Analysis and Testing of a Web Application

1 Assessed Learning Outcomes

This coursework counts for 70% of the total assessment of this module. It is designed to develop and assess your attainment of the following learning outcomes. 

In this coursework, you are required to work individually as a software quality assurance and testing engineer to perform testing and analysis of a given web-based application, and to develop test suites for automated regression testing of the application

The application is the website of Manchester University at the URL https://www.manchester.ac.uk/ . The specific function of this web-based application to be tested is the online facility for finding undergraduate courses provided by the university. Here, we will focus on Computer Science, Accounting, or Biochemistry courses.

Note: The URL given is an external application beyond the lecturer's control; you must be prepared for possible changes to the website when you write your automated test scripts.

3 Tasks to do

The following is a brief description of the tasks and the marking scheme (in terms of the distribution of their weights in the assessment). A detailed marking scheme is given in a separate file, also available on the student’s website.

Task 1: Developing a test plan. (25%)

In this task, you are required to:

· Explore the website to be tested;

· Construct a hyperlink graph model of the application;

· Write a user story or a set of user stories in JBehave format based on the hyperlink graph model of the system. Each user story should include:

a) a narrative description of the user story

b) a set of scenarios of using the function

Note that your test plan should achieve node coverage and hyperlink coverage of the hyperlink graph model.

Task 2: Developing automated test scripts. (25%)

In this task, you are required to follow the steps below to develop a set of automated test scripts based on the result of Task 1.

a) Select a subset of user stories/scenarios (at least three) in your test plan as the test cases of your choice.

b) For each scenario of your choice, follow the scenario description to perform a manual test of the web application and record your manual testing process using Selenium IDE, which you are required to install on your computer by yourself.

c) Edit and revise the recorded test process of your manual tests to make automated test scripts that are suitable for future regression testing.

d) Group the test scripts for one user story into a test suite.

Note that your chosen test cases should be the most complicated and important ones. Please read the detailed marking scheme for the quality standard that your test cases should have.

Task 3: Performing automated testing (30%)

In this task, you are required to perform the following.

a) Execute the test scripts using Selenium IDE to test the application in the Firefox web browser and record test executions in a log file.

b) Translate your test scripts in Selenese into one Java JUnit Test Code and execute the Java Test Code using JUnit with your software to test the web application in the Chrome web browser. You are required to install Selenium WebDriver for Chrome and take screen snapshots to demonstrate the successful executions of test code.

Task 4: Measuring test adequacy (20%)

In this task, you are required to calculate the adequacy of your testing by measuring your test’s node coverage and hyperlink coverage of the hyperlink graph that you developed in Task 1.

4 Submission of Coursework
