Test Case Design for Money Management Application

Welcome to our fifth blog, hope you enjoyed our previous blogs!!. In this blog we will discuss in detail about the test case design for Black box testing and White Box testing for our application and finally last but not the least about the summary of changes.

Black Box Testing:

Black box Testing is the testing either functional or nonfunctional without reference to the internal structure of the component or system.

• Image Reference.
  

This method attempts to find the errors in the following categories:

1. Incorrect or missing functions.
   
2. Interface Errors.
   
3. Errors in data structures or External database access.
   
4. Behavior or performance errors.
   

The following table shows the five functional requirements which are being considered to perform Black Box Testing

Requirement-1:

As a user I want to secure my budget planner with the passcode.

Testcase-1:

Title: Log In Activity: Authentication of the user

2. In “Enter Passcode” field Enter the registered passcode.
   
3. Click Login Button.
   

Expected Result:

1. User should be able to login successfully, if the entered passcode matches with the registered passcode.
   
2. If the Entered passcode does not match with the registered passcode an error message should be shown “wrong password”.

White Box Testing:

White Box testing refers to a scenario where the tester deeply understands the inner workings of the component and its implementation.

• Image Reference.
  

The key Principles which assist in executing White Box tests successfully are:

1. Statement Coverage- Ensure every single line of code is tested.
   
2. Branch Coverage- Ensure every branch (eg: true or false) is tested.
   
3. Path Coverage – Ensure all possible paths are tested.
   

Flow charts help us to identify the possible branches and conditions to achieve maximum amount of code coverage.

The following Table shows the five functional requirements which are considered for the white Box Testing and the corresponding classes covered.

Summary of Changes:

There has been a change in our implementation of Displaying the transaction oververview. The tansaction overview will be displayed as a popup instead of list view.

That is all for now !
