What is Database Testing?

  • Structural tests validate components in a data repository that is mainly used for archiving, such as table and column tests, stored procedures and lookup tests, trigger checks, etc. Black box testing in a database involves checking data integrity and basic functionality. The test cases in this test include validation of incoming and outgoing data while executing functions.

        

    As mentioned above, these tests can be performed manually by performing operations from the application user interface to ensure that the correct data is returned after each operation, or by checking database records to obtain the results of the operation. Using these methods, you can thoroughly test the functionality of the database.

        

    White box test is used to validate database tables, data models, database schema, and more. Adheres to referential integrity rules and selects default table values ​​to check for database consistency. It also evaluates data integrity and consistency, which can include building complex queries to load and load the database and test its responsiveness. It not only stores important business information but also serves as the basis for the entire application.

        

    The main task is to make sure that all internal processes are working correctly and can retrieve data quickly, accurately, and safely. The database test verifies the integrity and consistency of data by checking the schema, tables, triggers, etc. of the application database under test. Database testing mainly consists of building SQL queries to validate and validate various operations, structures, and database attributes required by the application for which the database is intended.

        

    This process can include schema validation, CRUD operations, and transaction testing to ensure that the database is configured correctly. Stress and performance tests are also performed to ensure that the underlying database functions and procedures are working correctly. This test uses database functions, triggers, views, SQL queries, etc., and is verified by running the test module.

        

    Schema testing includes validating various schema formats associated with databases and also helps you find unmapped objects in the database such as tables, views, columns, etc. applications. Structural Database Testing - Structural database testing involves testing all items in the data repository that are used solely for data collection and are not directly available to end-users. This is where database testing comes in handy, which helps verify the quality, security, and correctness of the data that the application retrieves or stores in the database.

        

    To understand the key concepts of database testing processes, a database testing engineer must be familiar with the various features, types, manual and automated database testing processes, and database testing tools. We will assume that the readers of this tutorial have some practical experience with database management using SQL queries. For manual data testing, the database tester must have a good understanding of the structure of the database tables. As part of the white box test, examine the structure of the database procedure and extract test data from the logic/code of the program.

        

    Testing the integrity of database procedures. Testing the consistency of database procedures is similar to the unit testing process followed by development / QA teams to test code written in other languages ​​such as Java and C #. Typically, when testing a database, activities such as validating data, checking data integrity, checking performance, testing various procedures, triggers, and functions in the database are considered. Functional testing consists of verifying that the database complies with the customer's specifications and that the end-user actions comply with these requirements. The functional test is carried out from the point of view of the end-user; Whether the transactions and required operations performed by end-users comply with company specifications.

        

    The tests can include functional tests of the database: functional tests are performed from the perspective of the end-user to determine if the required transactions and actions performed by the end-users meet the business requirements. Testing schema or mappings, testing stored procedures and views, testing triggers, testing tables, and columns, and testing the database server. Non-functional testing includes running load tests, stress tests, checking minimum system requirements against business specifications, identifying risks, and optimizing database performance. Database testers work with application developers to properly test the scenarios in which the database needs to run.

        

    Database testing now refers to the process of verifying the data stored in the database by checking the objects that manipulate the data and the various functions surrounding the data. Database testing is a software test used to verify data validity, data integrity, database architecture, tables, procedures, triggers, and the performance of the tested database. The database is a software subsystem that provides an effective way to store user data and allows querying using a structured query language called SQL. In a database, data management becomes a very simple task, because we can use the database as a database to retrieve information, such as tables for storing data, functions, triggers for manipulating data, and mapping of data views.

        

    The database is one of the inevitable parts of a software application. The database is an integral part of any software, therefore its consistency and integrity must be controlled and created according to the application. Therefore, it is all the more important to know database testing and be able to effectively validate databases to ensure the safety and quality of the databases. Hence, it is important to test a database system that conforms to the ACID properties (atomicity, consistency, isolation, and lifetime) of the database management system.

        

    The most important layer is the data access layer, which directly deals with the database in the communication process. Database testing mainly occurs at this level and includes testing strategies such as quality control and quality assurance of product databases.

        

    Companies like Google or Symantec that are concerned with data storage need to have a reliable and consistent database system. Third, you need tools to help you bring your database to a known state, which implies the need to not only generate test data but also manage it (like other critical development resources, test data must be under the control of configuration management). You should also ensure that your test covers database activities such as data integrity, data validity, triggers, and functions in the database.

        

    All these different areas of the database and the storage of information and queries must be tested correctly. There are many tools on the market for generating test data, managing it, and finally performing database testing, such as load testing, regression testing, etc. Data mapping is one of the key aspects of the database, and every tester’s software must test it thoroughly.

        

    Also, create a data mapping sheet that should tell you the UI actions and the tables (and columns) that are affected by the execution of the action.

        

    But when there is a large amount of data in multiple database tables, this may be a tedious and tedious task. You need to know how to create databases and tables, insert records, modify tables, delete tables, delete records, and update records.
