How to find a job as a Database Tester?

Database testing involves assessing elements including schema, tables, or triggers. The process of database testing involves checking data integrity and consistency. In order to perform this, complex queries are created to load or stress test the database. Thereby, experiencing a rise in the demand for database testers. Moreover, the backends get more complicated as the front ends become more complex. As a result, it’s even more critical to learn about database testing and be able to successfully evaluate databases in order to assure database security and quality. Let’s first begin by understanding more about Database Tester and career opportunities

About Database Testing

Database testing entails writing SQL queries to assert and validate various database actions, structures, and characteristics that are required by the application for which the database is being used. Validating the schema, testing CRUD operations and transactions, and ensuring that the database is set up appropriately are all part of this process. These tests can be completely automated, completely manual, or a combination of both human and automated procedures.

In a fully manual test, for example, you might go into the database management system and perform queries to verify assumptions. Alternatively, you may test the application’s user interface to ensure that it delivers the proper data after a transaction.

Database testers collaborate with application developers to thoroughly evaluate the database’s scenarios. In addition to being knowledgeable with the database structure, a database tester should have a thorough understanding of the application’s business rules.

Let us now look at why should you get into the field of database testing.

Importance of Database Testing

When the integrity of data in an application is compromised, it can result in significant financial losses and perhaps the failure of the entire company. The severity of these repercussions varies, ranging from less data-sensitive features such as the amount of retweets on a tweet to the actual worth of stock on a trading platform. While database testing cannot avoid all data breaches or integrity compromises, it can help to reduce the worst effects by extensively evaluating the database system that an application uses.

The following are some of the most prevalent reasons for database testing:

  • SQL injection attacks, for example, must be avoided.
  • Assuring that network difficulties or power outages do not compromise data integrity, resulting in data loss or corruption.
  • To ensure data quality, mistakes must be removed from the database.
  • additionally, To ensure that each piece of data is saved in the correct format.
  • To verify the database’s relationships between entities.

Let us now look at the scope and job profiles in this domain.

Scope and Data Testing Job Profiles

The demand for database testers has been increasing over the past decade. On average, a Database tester earns an average annual income of $85,470, or $41 per hour. The richest ten per cent earns more than $109,000 per year, while the poorest ten per cent earn less than $66,000. Some of the job roles that you can expect after getting into this field are –

Senior Information Technology Manager

You will be responsible for maintaining the efficiency and performance of the organization’s technology and network systems as a senior information technology manager. You’ll keep an eye on technological infrastructures and operations to make sure they follow corporate rules and laws. You’ll examine computer system schematics and specs.

Senior Quality Assurance Analyst

A senior quality assurance analyst is a member of the quality assurance team who is in charge of the quality assurance process. They work on requirements and design documents analysis. Additionally, They do code reviews and assist in the quality assurance process as well as daily rituals. They also improve and develop the existing quality assurance methods. Other responsibilities include effectively managing existing bugs and logging new bugs, producing defect reports, status reports, and test reports as needed, raising product issues to the team as soon as possible, establishing metrics and best practices, and recommending review processes and methods, as well as communicating with internal teams such as developers and product owners.

Quality Assurance Lead

A quality assurance lead’s main responsibility is to supervise the testing of a product or service to verify that it meets industry and organizational standards. They assist in the development of testing plans, risk mitigation methods, and collaborating with the product team on process improvements. A quality assurance lead’s degree will vary depending on the industry. Working at a food production plant, for example, will need a scientific degree, whereas maintaining the TikTok platform will necessitate an IT degree.

Let us now have a small glimpse of how to test a database!

How to test a database?

These tests may be done manually, as I described before, by executing operations via the application UI to ensure that the correct data is returned after each action, or by verifying the database records for the operation’s outcomes. You may also use a database management system (DBMS) to perform your test queries and verify the results.

If you prefer not to test manually, you’ll be glad to learn that automated database testing is quite comparable to automated application code testing. The main change is that instead of application code, your tests are now executing queries. The stages in testing application code are also applicable:

  • Prepare your test environment
  • Run your tests using a test runner (e.g. Selenium)
  • Check and validate your results
  • Report your assertions

This is why a database tester’s most valuable skill is the ability to write SQL queries for each and every test scenario.
