How To Write Test Cases In Manual Testing With Example? A Complete Guide

Manual testing is a fundamental process in ensuring the quality and functionality of software applications. Writing effective test cases is a critical skill for any tester. A well-written test case can help detect issues early, ensure comprehensive coverage of the application, and facilitate a smoother development process. This guide will walk you through the steps of writing effective test cases with examples. Also, we will discuss how manual testing course or software testing courses may help you to learn all the required skills.

What is a Test Case?

A test case is a set of conditions or variables under which a tester determines whether an application or software system is working correctly. Test cases are designed to verify that the software behaves as expected and meets the requirements specified by stakeholders.

Importance of Writing Good Test Cases

  • Ensures Coverage: Comprehensive test cases cover all functionalities of the application, ensuring that no feature is left untested.
  • Facilitates Communication: Well-documented test cases serve as a communication tool between testers, developers, and stakeholders.
  • Enhances Repeatability: Test cases provide a step-by-step guide for testing, making it easy to replicate tests during regression testing.
  • Improves Quality: Detailed test cases help in identifying defects early in the development cycle, improving the overall quality of the software.

Components of a Test Case

  • Test Case ID: A unique identifier for the test case.
  • Test Case Description: A brief description of what the test case is verifying.
  • Preconditions: Any conditions that must be met before executing the test case.
  • Test Steps: Step-by-step instructions to execute the test case.
  • Test Data: Data used in the test case.
  • Expected Result: The expected outcome of the test case.
  • Actual Result: The actual outcome after executing the test case.
  • Status: Pass or fail status based on the actual result matching the expected result.
  • Remarks: Any additional information or comments.

Steps to Write Test Cases

  1. Understand the Requirements

Before writing test cases, thoroughly understand the requirements of the application. Review requirement documents, use cases, user stories, and any other relevant documentation.

  1. Define the Scope

Determine the scope of testing based on the requirements. Identify the features and functionalities that need to be tested.

  1. Identify Test Scenarios

Test scenarios are high-level concepts of what to test. They provide a broader view of the functionalities to be tested. For example, for a login feature, test scenarios might include:

  • Valid user login
  • Invalid user login
  • Password reset
  1. Write Test Cases

For each test scenario, write detailed test cases. Each test case should be specific, clear, and concise. Include all necessary information to execute the test case.

  1. Review and Validate

Review the test cases with peers, developers, and stakeholders to ensure they cover all aspects of the requirements and are understandable.

Example of Writing Test Cases

Let's consider an example of writing test cases for a login feature.

Test Scenario: Valid User Login

Test Case ID: TC01
Description: Verify that a user can log in with valid credentials.
Preconditions: User is on the login page.
Test Steps:

  1. Enter valid username in the username field.
  2. Enter valid password in the password field.
  3. Click the "Login" button. Test Data:
  • Username: testuser
  • Password: testpassword Expected Result: User is successfully logged in and redirected to the dashboard.
    Actual Result:
    Status:
    Remarks:

Test Scenario: Invalid User Login

Test Case ID: TC02
Description: Verify that a user cannot log in with an invalid password.
Preconditions: User is on the login page.
Test Steps:

  • Enter valid username in the username field.
  • Enter invalid password in the password field.
  • Click the "Login" button. Test Data:
  • Username: testuser
  • Password: invalidpassword Expected Result: User receives an error message indicating invalid credentials.
    Actual Result:
    Status:
    Remarks:

Test Scenario: Password Reset

Test Case ID: TC03
Description: Verify that a user can reset their password.
Preconditions: User is on the login page.
Test Steps:

  • Click on the "Forgot Password" link.
