A test case is a specific set of conditions or test scenarios designed to verify an application's functionality, behavior, or performance. A test case outlines the steps to be followed, the inputs to be provided, and the expected outcomes for a particular test. They cover all the features of the software, from testing a drop-down menu and clicking a button to validating search and payment pages.

Test cases serve as a detailed documented reference for testers to ensure that the testing is thorough and covers the complete application. And thus, it is important to create clear, well-defined, and comprehensive test cases that cover various scenarios and edge cases to ensure effective testing of the application.

Let’s take a basic example of login functionality and write a test case for it.

**Test Case ID:** TC001
**Test Case Title:** Login Functionality - Valid Credentials
**Test Case Description:** This test case verifies the login functionality of the web application using valid credentials.

**Test Steps:**

- Open the web application login page.
- Enter a valid username in the username field.
- Enter a valid password in the password field.
- Click on the "Login" button.
- Validate that the user is successfully logged in.
- Verify that the entered username is displayed on the home page.

These test steps will have expected and actual results, deciding whether the tests are passed or failed. The test case is passed if the expected results match the actual output.

## Advantages of Test Case

There are multiple benefits of writing and running test cases. These are some of the few advantages [test cases](https://hubs.ly/Q02hYXk30) bring to the testing process:

- Test cases cover the entire application features, including functional and non-functional aspects.
- They reduce the maintenance and support costs of the software.
- They provide a documented and repeatable process for executing tests.
- Creating and executing test cases offer improved product quality and customer satisfaction.
- You can link test cases to specific requirements or user stories, establishing a traceability matrix.
- They provide a basis for reporting and analysis of the results.
- By following a set of test cases, you ensure that your application satisfies user-end requirements as per their expectations.

## How to Write a Test Case with Testsigma?

Testsigma is a no-code, AI-powered test automation tool that makes use of NLPs to create test cases. You can either generate tests by using the record-and-playback option that converts every interaction with the application under test into a test step or write your own cases in plain English.
Testsigma dashboard, where you can create a new test case, looks something like this:

While developing the test itself, you can choose either to record or the manual option. If you choose manual, you can create test cases according to your requirements using NLPs. The below image shows the multiple NLP options available to create tests.
