The Database can be tested various ways, If we are using SQL server then open the SQL query analyzer and write the questions to retrieve the data. Then verify whether the expected result is correct or not. IF not the data is not inserted into the database.

Database testing is one of the important testing, which desire tester to skilled in checking tables, writing questions and procedures. Testing can be achieved in a web application or desktop and database can be passed down in the application like SQL or Oracle. There are several projects like banking, finance, health insurance, which depend upon extensive database testing.

Database testing basically includes the following:

1. Data effectiveness testing.
2. Data Integrity testing
3. Performance allied to the data base.
4. Testing of program , triggers and functions.

Currently database is getting more complicated due to the business coherence which plays a crucial role for the applications. QA should make sure that values have been added correctly after the implementation of the business rules.

Database testing is really a complex undertaking and it should always be transact if the tester is much veteran in this field.

Check all the functionality which is happening on every flurry performed in the application. Actions can comprehend deletion, addition or save benefits . Check whether the added record is joined in the DB with the clear-cut value. Check the deleted record gets expunged from the database. These are exceeding roles which need to be keep an eye on seriously.

There are many database tools available like MS-Access2010, MS SQL Server 2008 r2, Oracle 10g/11g, Oracle Financial, MySQL, PostgreSQL, DB2, etc. The software applications must be developed using any of the database tools.

Apache JMeter has a built-in JDBC Request module. We can do database testing with JMeter. Let’s see how!

JMeter can connect to any database and run SQL queries concurrently. In order to do so, it’s mandatory to have necessary JDBC drivers in the lib folder of your installation.

The most important part of the Database performance testing is to have valid connection strings in the JDBC Connection Configuration.

What are the possible test scenarios for database testing?

Here, we are listing down three types of scenarios possible for testing a database.

General Test Scenarios

General tests should capture the following scenarios.

• Name of the database.
• Name of the log file.
• Disk space allocation for databases.
• Names of all tables, columns, and their types.
• Null value checks.
• Verify the keys (primary/foreign), indexes, and data types of columns used.

Functional Test Scenarios

• Identify events causing the triggers
• Functions inside stored procedures and possible combinations.
• End to end data flow starting from the front end to the back end.

DB Test Driven

DB Test Driven is a unit testing framework for database test-driven development. DB Test Driven is an open source framework.

DB Test Driven can support the following database environments,

• SQL Server
• Oracle
• Netezza

Two main test scenarios performed by Database Benchmark are,

1. Insertion of large amounts of randomly generated records with sequential or random keys
2. Reading the inserted records, ordered by their keys

Closing notes!!!

We wish that you should now know what database testing is all about, the challenges that you could face while carrying out database testing and how to devise an effective database test strategy.
