Data of any application is always critical from a business perspective. If basic database operations such as insert, update delete are performed without testing database for consistency then there is a risk of entire system crash. Database testing is nothing but finding errors in the databases to eliminate them.

Basic Database Testing
This document discusses different types of database testing including:
1) Checking the database connection is valid by executing test queries and handling exceptions if the connection fails.
2) Validating data types by checking that received values match the expected number and type of values.
3) Performing input verification by checking input field lengths and formatting.
4) Ensuring data integrity by verifying related entities after data is inserted, updated or deleted.
5) Testing backups by restoring data and verifying accuracy by comparing table structure and rows to the source database.
Database Testing
The document discusses various types of database testing including data integrity testing, stored procedure testing, data type testing, data size testing, event driven testing, and input item verification. Data integrity testing ensures that changes to data, like updates, deletions, and insertions, properly update related entities. Stored procedure testing involves testing individual functions and validating modularity. Data type testing checks that data types match between developers and database administrators. Data size testing verifies performance with large amounts of data bypassing front-end validation. Event driven testing checks triggers and scheduled actions. And input item verification tests for proper data validation of user inputs.
Testing database applications with QuickCheck
This document provides an overview of using QuickCheck to test business rules in database applications. It defines database applications as software that makes intensive use of data and relies on external storage for persistence. Business rules impose complex constraints on the data and their enforcement is critical to correct application operation. However, business rules are not confined to a specific component and are thus difficult to test with traditional unit or integration testing. The document proposes using QuickCheck, a random testing tool, to generate test cases and sequences to verify an application complies with business rules imposed on data at all times during system-level testing. It outlines representing the application interface, logic and storage access as a QuickCheck state machine to facilitate automated testing of business rules.

Database Testing
Database testing involves validating that database operations produce the correct results according to requirements. This includes ensuring data accuracy, proper handling of insertions/deletions/updates, and that the database schema correctly models real-world data. Key aspects to test include data mapping between the user interface and database, adherence to ACID properties like atomicity and isolation, data integrity across interfaces, and conformity to business rules using techniques like constraint and trigger testing. Thorough database testing from the early stages is important for complex systems, as backend/database bugs could cause whole projects to fail.

Automated Testing with Databases
The document discusses when and how to include database access in automated tests, providing alternatives like using mock objects or resetting test data. It demonstrates techniques for resetting test databases using tools like DbUnit or transaction rollbacks. The main considerations are balancing test speed versus fully testing database interactions while maintaining independent, repeatable tests.
Mind Map Test Data Management Overview
The document discusses test data management and creating a mindmap to help organize test data management tasks. It outlines best practices for test data management, including identifying data sources, extracting and transforming data, provisioning data for testing, and maintaining test data over time. Creating a mindmap helps visualize the important tasks, reduce effort spent on test data preparation, and leads to improved testing quality through more accurate test data.
Etl testing
The document discusses testing for a data warehouse. It describes requirements testing to validate requirements, unit testing of ETL procedures and mappings, and integration testing of ETL job sequences and initial data loading. Integration testing also covers end-to-end scenarios like count validation, source isolation, and data quality checks. Report data is validated by verifying it against source data. User acceptance testing tests the full system functionality. Continuous testing is needed as data warehouse schema and data evolve over time.

The document discusses different types of software testing including white box (structural) testing, black box (functional) testing, unit testing, integration testing, system testing, acceptance testing, and performance testing. It also outlines the stages of testing in the V-model including unit testing, integration testing, and system testing. Various testing techniques are described such as testing code structure in white box testing and testing functionality without viewing code in black box testing.
Oracle database performance diagnostics - before your begin
This is an article that I had written in 2011 for publication on OTN. It never did appear. So I am making it available here. It is not "slides" but is only 7 pages long. I hope you find it useful.
System testing
System testing evaluates a complete integrated system to determine if it meets specified requirements. It tests both functional and non-functional requirements. Functional requirements include business rules, transactions, authentication, and external interfaces. Non-functional requirements include performance, reliability, security, and usability. There are different types of system testing, including black box testing which tests functionality without knowledge of internal structure, white box testing which tests internal structures, and gray box testing which is a combination. Input, installation, graphical user interface, and regression testing are examples of different types of system testing.

Database testing for beginners
- 1. Database Testing for beginners Data of any application is always critical from a business perspective. If basic database operations such as insert, update delete are performed without testing database for consistency then there is a risk of entire system crash. Database testing is nothing but finding errors in the databases to eliminate them. What to Test? a. Data Validity testing – When data is entered via front end ,check if the data is correctly updated in the backend database. Check how special characters are handled in the database .Check that right columns in the right tables are being updated. Such checking usually involves use of SQL queries to validate the data. b. Data integrity testing – It involves testing of appropriate changes to the related entities and constraints such as primary key/foreign key ,when data is modified ( insert, update, delete) c. Data format testing – This involves checking the size and type of fields that store data in the database with those that accept data in the application. for example application may accept email id from front end but store without ” @ ” in the database. d. Database code testing – It involves testing the code in the database which implements business logic. This includes testing of stored procedures. e. Non-functional database testing – To ensure database scalability ,recoverability with no/minimal loss of data it is important to do database performance testing, database security testing, database recovery testing etc. How to Test? a. Firstly tester needs to understand entire application completely and which database is being used with the application. need to have understanding of database structure and data mapping ,understand validations and constraints ,creating queries etc. b. Figure out all the tables which exists for application and try to execute all the queries for the tables as there are many complexities present. Check each and every table carefully using the appropriate data. Check all the functionalities present in the application. c. If the complexity is more than tester can get the queries from developer to check the required functionality.
- 2. The world is generating variety of data with a huge volume at a very rapid speed . database is getting more complex due to the business logic which is an important aspect of the application. Database testing is really a complex task and it should be always performed if tester is much experienced in this field. it requires tester to expertise in sql and stored procedures.
