## What is CRUD Testing? CRUD testing refers to the testing of Create, Read, Update and Delete functionalities in a software system. These are the basic functions that a software application should be able to perform. - Create: Testing whether new records or data can be created. - Read: Testing if the system can successfully retrieve or read the data from the database. - Update: Testing if an existing record or data can be updated or modified. - Delete: Testing if a record can be permanently deleted from the system. CRUD testing ensures that these functions work properly and helps to maintain data integrity and consistency in a system. --- ## Tags #SoftwareTesting #CRUD #QualityAssurance --- ## Derived Concepts 1. [[CRUD Matrix]]: A CRUD matrix is a table showing the interaction of different modules of a software system with the database. It helps in identifying the areas that require CRUD testing. 2. [[CRUD Operations]]: CRUD operations refer to the basic functions that a software application should be able to perform on a database. These operations are necessary for managing data in any software system. 3. [[Data Integrity]]: Data integrity refers to the accuracy, consistency, and reliability of data stored in a database. CRUD testing helps in maintaining data integrity by ensuring that the CRUD operations work properly. 4. [[Functional Testing]]: Functional testing is a type of software testing that verifies that each function of the software application operates as per the requirement specification. CRUD testing is a part of functional testing as it checks whether the basic functions of creating, reading, updating and deleting data work correctly. 5. [[Regression Testing]]: Regression testing is carried out to ensure that changes or modifications in one part of the software do not affect other parts. Since CRUD operations are fundamental to any system, any changes to these operations may have significant impacts on other functionalities. Therefore, [[regression testing]] often includes CRUD testing. 6. [[Black Box Testing]]: Black box testing is a method where the internal structure/design/implementation of the item being tested is not known to the tester. CRUD testing can be considered as black box testing as it focuses on input and output without knowing how and where the data is being stored or retrieved from. 7. [[Database Testing]]: Database Testing involves checking the integrity of actual data elements manipulated by an app or website. It's closely related to CRUD Testing because both involve verifying correct handling of data elements including their creation, retrieval, updating and deletion. 8. [[End-to-End Testing]]: End-to-end (E2E) tests check if an application works from start to finish from user's perspective ensuring all integrated pieces work together as expected which includes CRUD operations. 9. [[Smoke Testing]]: Smoke tests are designed to touch every part of an application in a cursory way without getting into too deep. It's a way to make sure all parts of an application are working together seamlessly including CRUD operations. --- ## Related Concepts 1. [[Software Development Life Cycle (SDLC)]]: The process of planning, creating, testing, and deploying an information system. CRUD testing is a part of the testing phase in SDLC. 2. [[Unit Testing]]: A level of software testing where individual units/components of a software are tested. CRUD operations can be tested individually as a part of unit testing. 3. [[Integration Testing]]: A level of software testing where individual units are combined and tested as a group. CRUD operations are often tested together to ensure they work cohesively. 4. [[System Testing]]: A level of software testing where a complete and integrated software is tested to verify that it meets specified requirements. 5. [[Acceptance Testing]]: The process of conducting tests to determine whether a system satisfies its acceptance criteria and to enable the customer to determine whether to accept the system. 6. [[Performance Testing]]: Performance testing is done to check how the system performs under heavy load or stress conditions. CRUD operations are often subject to performance tests to ensure they can handle large amounts of data efficiently. 7. [[Security Testing]]: Security testing aims at finding out how well the system protects against unauthorized access, hacking, data loss etc. CRUD operations need to be secure as they deal with sensitive user data. 8. [[Usability Testing]]: Usability testing is done to check if the system is user-friendly and easy-to-use for its intended users which includes ease of performing CRUD operations. 9. [[Compatibility Testing]]: Compatibility tests check that your application can run on different hardware, operating systems, applications, network environments or Mobile devices which includes smooth execution of CRUD operations across all platforms and environments. 10. [[Load Testing]]: Load test is type of performance test where the application is subjected to load in terms of concurrent users or requests per second which includes checking performance of CRUD operations under high load conditions. 11. [[Stress Testing]]: Stress testing is a type of performance test where the system is subjected to extreme workloads or conditions such as large number of users, large number of transactions, limited memory, limited disk space etc., which includes checking how CRUD operations perform under extreme conditions.
