Test Cases for Integration Testing in 2023

Hi Testers!, In this article, we will cover “Test Cases for Integration Testing“, Positive Test cases and Negative Test Cases.If the interviewer asks you to write the test cases, do not assume the requirements.

It would be great if you asked for requirements that help you write the best test cases and test scenarios. Let’s get started.

Test cases for integration testing are like the rules of engagement for this meeting. They’re there to ensure that every component plays nice and works well with others.

Positive Test Cases

• Verify that the transition between two interconnected modules is smooth and error-free.
• Verify that data inputted in one module correctly shows up in the related module.
• Verify that multiple users can operate different modules at the same time without any hiccups.
• Verify that switching from one module to another doesn’t cause any performance issues.
• Verify that all links connecting various modules are working as intended.
• Verify that updates in one module are accurately reflected in the database.
• Verify that all functionalities perform as expected when two or more modules are combined.
• Verify that integrated modules can communicate with external systems without any issues.
• Verify that the security features of the application are not compromised during module transitions.
• Verify that appropriate error messages are displayed when an error occurs in an integrated module.
• Verify that the user interface elements interact properly across different modules.
• Verify that the back-end services support the operations of the integrated modules.
• Verify that the application handles peak load conditions smoothly when multiple modules are integrated.
• Verify that the application maintains session continuity across multiple integrated modules.
• Verify that the data validation works properly between integrated modules.
• Verify that the application’s response time is within acceptable limits after integration of modules.
• Verify that the recovery from failure of one module does not impact the functioning of other integrated modules.
• Verify that the integrated modules do not have any memory leaks.
• Verify that integrated modules do not deadlock when accessed simultaneously by multiple users.
• Verify that the integrated modules work correctly on different operating systems and devices.

Negative Test Cases

• Verify that the application displays an error message when incorrect data is shared between modules.
• Verify that the application can handle abrupt termination of a module without crashing.
• Verify that the application remains stable under an overload of simultaneous requests.
• Verify that the application does not crash when there is a failure in one of the integrated modules.
• Verify that the application handles scenarios where one module sends data that the receiving module cannot process.
• Verify that the application recovers gracefully from an unexpected shutdown during transition between modules.
• Verify that the application prevents unauthorized access during transitions between modules.
• Verify that the application does not lose any data during an unexpected interruption in the communication between modules.
• Verify that the application does not slow down significantly when a module fails to respond.
• Verify that the application does not display incorrect data if there is an error in one of the integrated modules.
• Verify that the application does not allow data corruption during communication between integrated modules.
• Verify that the application does not allow deadlock situations when multiple modules are accessed simultaneously.
• Verify that the application returns to a safe state after a system crash during module integration.
• Verify that the application maintains data integrity when there’s a sudden power loss during module integration.
• Verify that the application does not have memory leaks when an error occurs in one of the integrated modules.
• Verify that the application does not allow unauthorized user login during module integration.
• Verify that the application does not allow data breaches during communication between integrated modules.
• Verify that the application does not crash when there’s a network disconnection during module integration.
• Verify that the application does not allow data duplication during communication between integrated modules.
• Verify that the application does not crash when there’s a hardware failure during module integration.
