In software development, there are various types of test cases to ensure the application works as expected and meets all the user/stakeholder requirements.
Here are the main types of testing, particularly relevant to Next.js and React.js applications.

• Unit testing: Unit testing involves testing individual components or functions to check it is working properly.

• Integration testing: It focuses on testing the interaction of two or multiple components together to ensure they are working as expected.

• End-to-end testing: End-to-end testing involves testing the application from start to end to make sure all parts of the app work properly together.

• Acceptance testing:: Acceptance testing makes sure that the application meets all the acceptance criteria/requirements of the users/stakeholders.

• Regression testing:: It involves re-running the previous tests again to make sure the application works properly after the recent changes.

• Performance testing: Testing the application in various conditions such as load, stress, and scalability.

• Security testing: It involves identifying vulnerabilities in the application and ensuring the application is protected against threats and attacks.

• Usability testing: How easy and user-friendly is the application for end users.

• Compatibility testing: Testing the application across different devices, browsers, and operating systems to make sure it works correctly for all.
