As its name suggests, database testing ensures databases’ security, performance, and functionality. In a world where everything relies on data and big data, it’s imperative to rely on well-performing databases. But how does it work, and can anyone make a career out of it?
This post reviews the importance of database testing, along with some of the most popular database testing interview questions. Software and tech job interviews are famous for being hard, but preparing yourself for the toughest questions can be a game-changer. That said, let’s dive in.
First thing is first – What is database testing? Mainly, it involves creating SQL queries to validate the database operations and structures. The process includes anything from validating the schema to testing CRUD operations. At the end of the day, the goal is to ensure the database functions and all the data is reliable.
To become a database tester, one needs to understand the structure of a database. For example, a tester might test the application UI to determine whether it returns the correct data after the operation. But how can you do that if you don’t grasp the fundamental concepts? That is where platforms like us at Test Pro come in handy, as they provide their students with online courses and bootcamps.
There are different types of testing when it comes to databases:
Okay, but how do you actually create and run a test? As with other tech fields like quality assurance, these tests can be manual or automated. That means you can either run queries manually to validate assumptions (manual) or test the application UI (automated). Automating tests is more efficient and gets the job done quicker, and being proficient at it can give you an advantage over other testers.
SQL test is one of the most popular ways to test databases. This tool allows anyone to write unit tests for SQL server databases. Unit testing focuses on verifying individual components of particular software applications (the smallest testable parts of a program, such as functions). It answers questions like: Do these small parts function correctly, execute fast, are automated and scalable, etcetera?
Other popular database testing tools include:
Now, what are some of the most popular database testing interview questions? What must you be familiar with before entering a job interview room? Well, here are some key concepts a database tester must master:
And more. Of course, one can never guess the questions of an interview. But the more you prepare for these inconveniences, the higher your chances of nailing the interview. If you want to build a career in tech and software testing, make sure to check Test Pro’s courses.
Database testing involves creating SQL queries to validate the database operations and structures. Mainly, it’s about ensuring the database returns the correct data, runs smoothly, and is secure.
SQL Test is a tool with pre-written SQL tests to make testing easier. It helps individuals write and run unit tests for SQL server databases.
One can test databases either manually or automatically. The latter saves time and resources for the company, and thus aspiring testers must become proficient at automating tests that run efficiently. The market is flooded with options to make the job easier, like SQL Test.
As the name suggests, this software testing focuses on verifying individual components of particular software applications (the smallest testable parts of a program, such as functions).
In 2022, the US software testing market will be valued at $6.8 billion, with up to 56% of QA testers being self-taught. This indicates two things. The first is that the software testing sector has enormous growth potential. Second, if you want to work as a QA tester, you may start now and succeed.
The world of tech has so many career options that it can be overwhelming to choose one. In this blog post, we review and compare two careers in vogue: data science and full-stack development. As the tech world continues to evolve, it gets even more challenging to decide whether to become a full stack developer […]
If you’ve always wanted to work in software development, you’ve definitely come across two terms – quality assurance (QA) and software testing. These concepts are often intertwined, so most beginners may find themselves confused by these two different terms. In order to avoid this, we suggest that you take a look at this article, where we will look at the subtle difference between QA and software testing, we will highlight the uniqueness of each of them for the field of IT and also we will find out why you should start your career as a tester with the help of Test Pro.
