Midterm Grading Program Test Report

1. Introduction
This document is the Software Test Report for Midterm Grading program. The intended audience is the
Testing Manager and the Tester. It contains the type of tests to be conducted, the input to be entered or code to
be executed during the testing phase, the expected outcome of the test, and the status of the test scenario.
2. The Application
The application collects data for a student’s midterm grades in a specific semester. It allows the user to
enter five grades, values 0 to 100, and calculates the overall average. It then assigns a grade and displays the
result bellow the submit button. The user enters a name and score of each course. This is used to calculate and
display the letter grade average of the courses entered.
Figure 1 Application
The tester will be provided with the application, the source code and a controlled testing environment.
To test the application the tester will enter a series of values in the application and observer the outcome. The
tester will try several different combinations of inputs and report the results in the table provided in the test case
section of this report.
The tester is also provided with the code for the application. Using this the tester is to conduct tests by
hard coding values and testing any decision or condition lines of code. The tester then reports the results in the
table provided in the test case section of this report.
3. Test Environment
The test environment consists of a MacBook Pro with Mavericks (OSX 10.9.1) operating system,
running Windows 8 Pro (64 bit, 8.1 edition) in Parallels Desktop 8 for Mac virtual environment. The MacBook
Pro is a 2 GHz Intel Core i7 with 8 GBs of memory. 2 GBs of memory and 4 cores have been designated to the
operation of Windows 8 under the Parallels virtual environment.
Figure 2 Application Running on Windows 8 in Parallels Desktop
The code will be inspected using Mac version of Sublime Text 2 that shows line numbers. The code will
be then modified and tested piece by piece, as the test cases require.

4. Test Plan
The test will be conducted in two stages. The first stage will look at the application by using various
inputs and observing the outcome. The second stage will look at the code and conduct tests on the lines of code,
as well as the conditional statements and test the logic. The instructions and expected outcome are available in
the table in the test case section. The tester will enter the results in the table in the designated area.
Using black box testing technique, for this application, the test cases will use boundary value analysis,
equivalence partitioning and error guessing. Using white box testing technique on the code, the test cases will
use condition coverage, decision coverage, logic coverage, multiple-condition coverage and statement coverage.
5. Effort Estimation
Due to the small size of the application, the phase one tests should take about one to three hours for a
tester to complete. Phase two tests will take about three to six hours due to the number of lines of code. Overall
the test should be complete in about one day.
6. Risks
Even though this program is small, there are some possible risks involved with this project.
Illogical processing: There is a possibility of errors within the code that allow the program to show
correct and incorrect results. The programs failure to detect the data types entered or failure to check if the
correct values are entered will allow the program to still calculate a result. The tester should be aware of this
and continue the test as instructed.
Program errors: There is a possibility of errors in the program that cause it to crash. Due to the nature
of the testing environment using a virtual machine we can mitigate critical errors that cause the system to crash.
If the errors cause major system problems, we can close that instance of the virtual machine and start a new one
without wasting time on resetting the computer.
Cascading errors: Failure to detect illogical errors and program errors have a way of triggering new
errors. There may be deeper issues with the program that the tester should be aware of during testing phase.
