How to write manual test cases for web application

Here are the steps to write manual test cases for a web application:

Understand the requirements: Before writing test cases, you need to understand the requirements of the web application, the features it offers, and the user interactions.
Identify the test scenarios: Based on the requirements, create a list of test scenarios that need to be tested. These test scenarios should cover all the features and functionalities of the web application.
Create test cases: For each test scenario, create a set of test cases. A test case should have a unique identifier, a description of the scenario, steps to be performed, expected results, and actual results.
Group test cases: Group similar test cases together to avoid duplication and make it easier to manage.
Prioritize test cases: Prioritize the test cases based on the criticality of the feature and the frequency of use.
Create positive and negative test cases: Create both positive and negative test cases. Positive test cases check if the web application is working as expected, while negative test cases check how the application behaves when invalid or unexpected input is given.
Test data: Identify the required test data, which should be used to validate the test cases.
Execute test cases: Execute the test cases and document the actual results. If the actual results are not as expected, document the defect and report it to the development team.
Retest: After the defects are fixed, retest the application to ensure that the issues are resolved.
Document the test results: Document the test results and share them with the team. The documentation should include the test cases, the actual results, the defects, and any relevant screenshots.
