5 Essential Skills Every QA Engineer Should Have.

Software testing is a sophisticated and challenging process. To verify that the programmer fulfils all performance standards and requirements, QA engineers are needed. In the United States alone, nearly 500,000 individuals work as Software Testers. In the United States, the average compensation for a Software Tester is $82,000. From $18.9 billion US. Dollars in 2018 to $36.8 billion by 2023, the software testing business is predicted to increase at a CAGR of 17.7 per cent.

Since 2010, QA engineers have risen by over 50%. More than 4.5 million QA Engineers are involved globally now, with an average annual income of $77,000 and a growth rate of 24 per cent.

Qualifications Required for This Job Role

Software testing is reviewing software to ensure that it fits its specifications. In addition, QA engineers perform program testing to ensure that the software is bug-free and fit for usage. As a result, QA engineers must comprehend the foundations of computer science, programming languages, and software development techniques. They must also be familiar with test automation technologies such as Selenium, Appium, and Cucumber.

Qualifications for becoming a QA Engineer differ based on the firm and sector. However, they often demand a bachelor’s computer science degree or technology, programming knowledge, and hands-on familiarity with various programming languages and tools. They must also be capable of programming and debugging. They must also be able to work with multiple operating systems, databases, and programs.

Qualifications for becoming a QA Engineer:

  • A degree is required in computer science, engineering, or a related field is recommended.
  • Knowledge in software engineering, programming, scripting, and functional testing is required.
  • Programming languages such as Java and Python are preferred.

Job Role and Responsibilities of a QA Engineer

QA Engineers are in charge of software testing and guaranteeing that it fulfils the quality requirements of the firm. They collaborate with developers to ensure that their work is error-free and that the product is ready to be released. QA Engineers also uncover possible faults or issues before they occur, allowing them to be rectified before the product is released.

Quality technician are also in charge of developing test cases and processes, evaluating data collected by automated tests, finding possible issues with the product under production, fixing problems through debugging or code modifications, and reporting results to the developers.

QA engineers often work on-site at organisations that manufacture software, but some work remotely. A typical day for a QA engineer may contain the following tasks:

  • Trying out different features in programming environments
  • Having to work on error reports from earlier application versions
  • Briefing with programmers to assess the progress

Skills Required to be a QA Engineer

QA engineers need strong analytical skills, critical thinking, and problem-solving abilities. They should be able to identify bugs and errors in software. They must also know how to use tools like bug tracking, issue tracking, source code repository, test automation frameworks etc. QA engineers are the backbone of software development. These engineers are responsible for the quality assurance process for their products.

Here are some of the essential skills QA engineers require –

  • Problem-solving abilities

QA engineers need to have problem-solving abilities to carry out the testing process effectively. They should be able to identify the root cause of an issue and find a solution for it. Problem-solving skills are essential for software testers. They must understand the code and find potential problems that may arise during the execution of a test plan.

Software testing is a complex process that involves different aspects such as design, development, quality assurance, and operations. Therefore, QA engineers need to have problem-solving skills to carry out their tasks in this field effectively.

  • Critical thinking

Software testing is a complex job that requires many skills and the ability to think critically. For example, QA engineers need to be able to evaluate whether the software is being developed according to the requirements and how well it is working with other software. They also need to be able to identify bugs and ensure that they are fixed as soon as possible.

There are many reasons why QA engineers need critical thinking skills, but one of the most important is that it helps them improve their performance. For example, QA engineers are often tasked with ensuring that software meets its requirements. This is an essential job, but it can be challenging at times. Critical thinking can help QA engineers to make the right decisions at the right time.

  • Analytical skills

The way QA engineers use analytical skills will determine how successful they are in their job. They must be able to identify problems with code and code flow, analyse user feedback, and evaluate performance data. QA engineers are responsible for the quality of the product, not just for its functionalities. Therefore, they need to understand how the software works and what makes it tick to identify issues that could lead to bugs or defects.

QA engineers should be able to think their way through problems and find solutions that work for all types of users. They should also be able to communicate with other team members, such as developers, designers, project managers and stakeholders.

  • Knowledge of programming languages

QA engineers are the ones who test software for bugs, functionality and performance. Therefore, they need to know programming languages to test software effectively. In addition, QA engineers need to be able to identify and pinpoint errors in the software they are trying. Therefore, they should know programming languages like Java, C++, Python, etc. 

QA engineers also need a deep understanding of the logic behind the code they are testing to identify problems with it correctly. They play a massive part in ensuring that the software is high quality and delivered as expected.

  • Debugging tools

One of the essential jobs in software testing is debugging. It is a process that involves finding and fixing defects in the software. QA engineers need to know about debugging tools because they are an integral part of software development.

Debugging tools are used by developers, testers, and QA engineers to find and fix bugs in the software. This can be done manually or with the help of automated tools like debugger, profiler, and code coverage tools. Debugging tools can also be used for performance analysis, memory leak analysis, etc.

Debuggers are also used for analyzing how programs behave under different conditions. For example, they help identify why a program crashes or behaves as it does during a specific execution stage.

How and where to Learn?

Software testing is a skill that is not easy to learn. It requires a lot of practice and experience to be good at it. However, many online resources can help you understand the basics of software testing. The most important thing in learning software testing is having a goal or knowing what you want to achieve from the skill. For example, if your goal is to make sure your company’s website works as expected, you need to know the desired outcome of your test before you start running tests.

Here are some options for you to consider based on your preferences:

  • Self-Guided Websites and Courses
  • Books
  • Virtual Classes
  • Non-Virtual Classes
  • Starting Your Projects
