How to Write Test Cases for Notepad? [Sample Test Cases]

Notepad is a simple but essential and well-known text editor application that is there in every computer. It is a fundamental yet very important tool found in various operating systems that helps people with tasks such as taking down notes to implementing source codes. 

Every software application, including Notepad, should be tested thoroughly to achieve its quality goals. Most of the quality engineers start their manual, automation or API testing journey by creating test cases for simple applications such as Notepad as it’s a well-known platform for helping testers to learn their ABCs. 

With this article, we are going to have a look at how to write test cases for Notepad, considering various test scenarios with sample test cases for Notepad, including text editing, file operations, and some other major user interactions.

Test Cases for Notepad

Test cases for Notepad should include different tasks like typing, saving files, using shortcuts, and interacting with menus. These test scenarios for Notepad should cover both positive scenarios, where the application behaves as expected, as well as negative scenarios, where unexpected inputs or conditions could lead to errors or unexpected behaviors. By testing Notepad considering various test scenarios, testers can verify its usability, smooth flow, and adherence to user expectations.

Before we discuss the test cases, lets also discuss the methods of testing that can be employed for those test cases:

Methods of testing:

Notepad can be tested using both manual and automated methods. When testing manually, quality engineers can use a step-by-step guide on each test case and track results. As usual, automated testing makes the process easier for the testers and the tests can be executed using various frameworks and tools such as Testsigma.

Manual

In manual testing, testers usually simulate real-world user activities while verifying the application’s usability and user experience. When testing Notepad with the help of manual testers, they interact with Notepad’s user interface and manually perform testing tasks such as typing, editing, saving, printing, etc. 

Additionally, manual testing involves testing edge cases and performing actions considering the end user’s perspective as well. On the other hand, testers can identify issues such as UI improvements, requirement confusion, functionality inconsistencies, performance slowness, etc through manual testing. 

Automated

Automating test cases using tools is the easiest way of testing the Notepad application. Let us get to know how to write a simple test case for the Notepad using Testsigma.

1. First of all, you can log in to the Testigma application and you will be navigated to the Testigma dashboard.
   

2. There you can hover on the “Create  New” button which is located in the top left corner and click on the “Test Case” option.
3. There you will be navigated to the “Create Test Case” screen. You can give a meaningful name for your test case. In this instance, we can give a name such as “Verify whether the user can open existing text files by selecting the “Open” option from the file menu”.
   

4. Then you can add the respective test steps for the test case you have written.
5. Add assertions for each test step.
6. Let’s simply click on the “Run” button at the top.
7. In the Adhoc section, you can configure the run settings by changing information such as Operating System, Resolution, Headless Run, etc.
8. After configuring those settings and executing the test, you will be able to see the results of the test run.
