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.

- 2. Check Valid Connection Connection validation is especially important in real time applications, which must run with no or minimal downtime. test is performed to verify the database connection is active/up. In fact, there can be various situations where a connection can be lost (e.g., because a database is down or there are some network problems). We can test this with two approaches. Using Vendor specific API Test-Fail query approach. GuyFromChennai.com Kumar S
- 3. Check Valid Connection Action Select the Connection string with the required credentials Execute the connect Factory Method Test the returned value(s) for successful connection. If the exception corresponds to a closed connection, try to re-establish a connection and re-execute a query. If the same exception is thrown, then try connecting to the failover database. Note: Obviously, this business logic with database connection handling. GuyFromChennai.com Kumar S
- 4. Data Type Validation Action This test is performed to verify that the data type used by the DBA are same as expected. Check the received values with the no of expected values If the No of values match then Check for the data type with the fields' data type If data types match then allow the actions like Insert, Update Else throw exception Else throw exception GuyFromChennai.com Kumar S
- 5. Input Verification Action This is the process of input data validation. Though it is not totally a part of database testing, this has to be performed essentially during database testing. The input items are tested for validation in the front end Check if the Maximum field length is correct Check for any junk/special characters in the input If any of the above fails throw exception GuyFromChennai.com Kumar S
- 6. Data Integrity Action This test is performed when anyone of the data undergoes any of the actions below, Insert Update Delete After the actions mentioned above, the db should be verified for the changes performed on related entities such as Primary Key Foreign key and any other Dependant entities If there is any error/mismatch , then rollback and throw exception GuyFromChennai.com Kumar S
- 7. Backup & Restore Action This test is performed to ensure the backed up data is valid and accurate Backup the whole database schema try creating another schema Import all the data from the backup Check the data is accurate and same as the source database schema Check the No of tables and table columns are the same Check the rows are the same as the source schema If any mismatch then throw exception GuyFromChennai.com Kumar S
