Database Testing

Database testing requires verifying the reliability of the data. Ensuring the reliability and validity of the data is crucially important for the program analysis process. To ensure that the customers are provided with correct information and this information is put back on the database you need to access the data for accuracy, relevancy, currency and clarity. As a rule, the data contain much more defects than the application itself. In this case, you need to examine the sequence of actions to be performed, and test changes in the database. This approach to database testing consists in isolating the actions that modify the databases, as well as in inspecting the changed content for correctness. It is important that the tester should be aware of risk sensitive program areas and correctly prioritize test cases. Carrying out a risk assessment will enable you to identify higher priority test cases and reduce the risks to the product quality. Save yourself the trouble of recruiting expensive local testers by opting for independent verification and validation services. You deserve to improve the product quality at a reduced price.

Database testing is performed at two levels: data administration and user functionality. The database administrator can perform limited actions that are not available to the Web site’s clients.

The following checklist will help you to formulate a number of additional administrative test cases.

  1. Understand the database project.
  2. Establish the main risks.
  3. Understand the project security management tools; to understand what the user ID should be, so that the person can have write / read access to the database management tools.
  4. Understand the procedures for updating and improving databases maintenance.
  5. Make sure that the requirements have been met.
  6. Verify the performance and availability of the product when several users simultaneously perform the same task or make a request (and also include the maximum number of concurrent connectors to the app’s server according to the specification).
  7. Ensure that the backup and restore procedures work as designed, and do not affect the availability requirements.
  8. Make sure that the database allows for the maximum number of connections that the system must handle according to the project.
  9. Make sure that the database has enough space and memory for storing a certain amount of data. Expand the capabilities of the system if these physical limits on space and memory are exceeded.
