Here we will discuss database testing performance & tools. An application with more response time and poor performance can lead to huge problems. Database Load Testing is used to find any performance issues before you deploy your database applications for end users.
Database Load Testing helps you design database application for performance, reliability and scalability. Load Testing of Database applications involves testing the performance and scalability of your Database application with varying user load.
Database Load testing involves simulating real-life user load for the target Database application. It helps you determine how your Database application behaves when multiple users hits it simultaneously.
Load Testing
The primary target of Load Testing is to check if most running transactions have performance impact on the database. In load testing, you need to check the following aspects −
- The response time for executing the transactions for multiple remote users should be checked.
- With normal transactions, you should include one editable transaction to check the performance of the database for these type pf transactions.
- With normal transactions, you should include one non-editing transaction to check performance of database for these type of transactions.
- Time taken by database to fetch specific records should be checked.
Stress Testing
Stress testing is performed to identify the system breakpoint. Here the application is loaded in such a way that the system fails at one point. This point is called the breakpoint of the database system. Stress testing is also known as Fatigue Testing.
Determining the state of database transactions involves a significant amount of effort. Proper planning is required to avoid any time- and cost-based issues.
The most common stress testing tools are LoadRunner and WinRunner.
Tools
There are various tools provided by vendors that can be used to generate Test data, to manage Test data and perform database testing like Load Testing and Regression Testing.
A few common tools that are used are given below.
| Sr.No | Category & Description | Examples |
|---|---|---|
| 1 | Load Testing ToolsThese tools are used to put high usage loads on your database, which enables to determine whether your system’s landscape will stand up to your business needs. | Web PerformanceRad ViewMercury |
| 2 | Data Security ToolsThese tools are used to implement compliance and standards as per the information security regulations. | IBM Optim Data Privacy |
| 3 | Test Data generator toolsA tester uses these tools to generate the test data for a database system. These are mostly required when you have huge amount of data and you need sample to perform DB Testing. It is commonly used for Load and Stress testing. | Data FactoryDTM Data GeneratorTurbo Data |
| 4 | Test Data Management ToolThese tools are used to maintain version control for test data. You have to define the expected results and then you compare it with the actual outcomes of the tests. | IBM Optim Test Data Management |
| 5 | Tools to perform Unit TestingThese tools are used to perform regression testing on your database. | SQLUnitTSQLUnitDBFitDBUnit |
