CRUD is short for creating, reading, updating, and deleting. These are the four basic operations you perform on data in the persistent storage application. Here, persistent storage refers to the data storage devices that keep the data safe and store it even when the device gets powered off. An example of such device can be a hard disk that is unlike the random access memory that erases all the data stored on it once the system turns off. CRUD testing is under the black box testing technique that validates the software product functionality. As CRUD is all about databases, this test application is for SQL and other databases. There is enormous data in an organization. For instance, consider a simple employee database table. The data tables get updated every time someone joins the organization or leaves it. Similarly, if the employee moves to another department or gets promoted, the database tables go through upgradation. The testing technique here checks that the data stored complies with authentic values! Let us discuss the steps a test engineer follows while performing the CRUD test. Step 1: Know what to test The first step is to identify the things, or the database tables you need to test through this technique. It is essential that you know the applications you will be testing, as it will help you create the strategies that would work aptly on them. Step 2: Create a Plan The next step is to create a plan to test the application thoroughly. There are multiple strategies that are apt for the application under question. So, it is a task to figure out which plan of action you want to choose. Step 3: Write Test Cases Once you decide on the plan or strategies and the application is in the testing process, the next significant step is to write test cases. Make sure you have a test case for each element of an application so that everything gets checked thoroughly. This document works as a reference during the entire testing process as it shows what you want! Step 4: Execution The last step is to execute all the plans or strategies you decided to complete the test process. If the execution is successful, so will your test process. Test execution only needs to be done by proficient experts as the reports they generate speak about the success. In these simple steps, the test engineer can perform CRUD testing. It is reliable and highly efficient enough for the organization to trust them.
