What is a Test Case in Software Testing?

A test case refers to the actions required to verify a specific feature or functionality in software testing. The test case details the steps, data, prerequisites, and postconditions necessary to verify a feature.

It will lay out particular variables that QAs need to compare expected and actual results to conclude if the feature works. Test case components mention input, execution, and expected output/response. It tells engineers what to do, how to do it, and what results are acceptable.

The Objective of Writing Test Cases in Software Testing

• To validate specific features and functions of the software.
• To guide testers through their day-to-day hands-on activity.
• To record a catalog of steps undertaken, which can be revisited in the event of a bug popping up.
• To provide a blueprint for future projects and testers so they don’t have to start work from scratch.
• To help detect usability issues and design gaps early on.
• To help new testers and devs quickly pick up testing, even if they join in the middle of an ongoing project.

Standard Test Case Format

• Test Case ID
• Test Scenario
• Test Steps
• Prerequisites
• Test Data
• Expected/Intended Results
• Actual Results
• Test Status – Pass/Fail

While writing test cases, remember to include:

• A reasonable description of the requirement
• A description of the test process
• Details related to testing setup: version of the software under test, data points, OS, hardware, security clearance, date, time, prerequisites, etc.
• Any related documents or attachments testers will require
• Alternative to prerequisites, if they exist

Test Case Prioritization is vital while writing test cases in software testing. Running all the test cases in a test suite requires much time and effort. As the number of features increases, testing the entire suite for every build is practically impossible. Test case prioritization helps overcome these challenges.

How to write Test Cases (Test Case Example)

Let’s build a test case example based on a specific scenario. Here is a sample case.

• Test Case ID: #BST001
• Test Scenario: To authenticate a successful user login on Gmail.com
• Test Steps:
  • The user navigates to Gmail.com.
  • The user enters a registered email address in the ’email’ field.
  • The user clicks the ‘Next’ button.
  • The user enters the registered password.
  • The user clicks ‘Sign In.’
• Prerequisites: A registered Gmail ID with a unique username and password.
• Browser: Chrome v 86. Device: Samsung Galaxy Tab S7.
• Test Data: Legitimate username and password.
• Expected/Intended Results: Once username and password are entered, the web page redirects to the user’s inbox, displaying and highlighting new emails at the top.
• Actual Results: As Expected
• Test Status – Pass/Fail: Pass

Once test cases have been shaped, corresponding tests must be run on real browsers, devices, and operating systems. Remember that device fragmentation is a significant concern for every developer and tester. Every website has to work seamlessly on multiple device-browser-OS combinations. With 9000+ distinct devices being used to access the internet globally, all software must be optimized for different configurations, viewports, and screen resolutions.

Managing Test Cases Using Test Management Tool

1. Access Test Cases Section: Log into your BrowserStack Test Management account, navigate to your project, and enter the “Test Cases” section to start managing your test cases.
2. View and Organize Test Cases: Look over the list of test cases in your project and arrange them by priority or other relevant criteria to enhance management.
3. Edit Test Cases: Select a test case to see its details and edit information such as the title, description, test steps, and priority as necessary.
4. Add or Remove Test Cases: Integrate new test cases by clicking on “New Test Case,” or delete outdated or unnecessary ones to keep your repository organized.
5. Execute Test Cases: Run the test cases, monitor the progress of test executions, and track the results within the Test Management platform.
6. Review Test Results: Post-test execution, analyze the outcomes, identify any issues or bugs, and classify them for fixing.
7. Update Test Cases: Modify test cases based on the results or any changes in the application functionality.

Why use BrowserStack Test Management Tool for Writing Test Cases?

BrowserStack Test Management Tool offers several features that make it effective for creating and managing test cases for web and mobile applications:

• Efficient Test Case Creation: Use ready-made templates in text-based or steps-based formats for fast, consistent, and streamlined test case creation.
• Effortlessly Import from Zephyr Scale, Xray, TestRail, or CSV.
• Enhanced Test Case Authoring: Utilize features like quick additions, detailed forms, and a rich text editor for clear and comprehensive test cases, improving software quality.
• Customizable Test Cases: Adjust test details like priority, type, and status to meet project specifications, enhancing test accuracy.
• Efficient Test Case Management: Manage test cases effectively with bulk actions—edit, copy, move, and delete—boosting productivity.
• Advanced Search and Filtering: Find and organize test cases quickly with filters like status, Test Case Priority, ID, Title, and more.
• Integrated Workflows and Insights: Monitor test cases and runs with real-time insights into software releases, performance metrics, and trends.
• Robust Reporting: Utilize advanced reporting tools to track progress, pinpoint issues, and evaluate test outcomes, ensuring detailed quality assessments.

Common Features of Test Cases

• Likely to be revised and updated regularly: Software requirements can change depending on business priorities or customer preferences. If requirements change, test cases will have to be altered accordingly. The detection of bugs and debugging steps may also require test cases to be changed.
• Likely to involve clustering:Test cases in a single test scenario usually have to be run in a specific sequence or in a group. In this case, particular prerequisites of one test case will apply to other cases in the same sequence.
• Likely to be interdependent:Often, test cases can depend on each other. This is especially true for layered applications with multi-tier business logic.
• Likely to be used by testers and developers: Test cases are helpful for developers andtesters. For example, when devs fix bugs, test cases can be pretty valuable to replicate the said bug. In Test-Driven Development (TDD), devs create test cases to craft business logic, cover multiple test scenarios, and start writing code.

Best Practices for Writing Test Cases

• Prioritize clarity and transparency. Be clear, concise, and assertive in describing what the tester needs to do and what results they should ideally get.
• Focus on End-User requirements when writing sample test cases. Map test cases to reflect every aspect of the user journey. Use the Specifications Document and the Requirements Document to do so.
• Avoid repetition. If multiple tests can be executed with the same test case, use the Test Case ID to refer to the required test case.
• Keep Test Steps as minimal as possible. Ideally, keep it to 10-15 steps, if possible.
• Focus on achieving maximum test coverage. While 100% test coverage is rarely achievable, a high percentage can be attained with the right strategies.
• Create self-cleaning test cases. Test cases must revert the Test Environment to a pristine, pre-test state. Tests should not leave remnants of themselves in the environment when completed. This is an integral element of Configuration Management.
• Shape test cases for tests that return the same results no matter who runs them. Ensure that tests are self-standing.
