What is a Test Case?

A test case template is a crucial tool for verifying whether an application’s features are working as intended. It includes positive and negative executable steps along with pre-conditions, test data, expected results, and actual results. Test scenarios are high-level descriptions of what needs to be tested, while test cases are detailed, actionable steps to test those scenarios.

Why Write Test Cases?

Writing test cases ensures that all aspects of an application are properly evaluated for functionality and usability. This process helps developers and testers identify and fix issues early on, improving overall product quality. Comprehensive test cases can also significantly reduce the likelihood of errors and bugs reaching the end-user.

General Test Case Template Format

The standard format for a test case includes:

Step #1 – Test Case ID

Each test case should have a unique identifier for easy reference and organization.

Step #2 – Test Case Description

This section describes the specific test scenario and what the test case aims to verify.

Step #3 – Pre-Conditions

These are the conditions that need to be met before executing the test case, such as valid user accounts or necessary software installations.

Step #4 – Test Steps

Detailed, step-by-step instructions for executing the test case, typically including user actions and expected outcomes.

Step #5 – Test Data
