The day has come when I no longer have to justify the relevance or significance of software testing, right? Much like software development, even software testing turns out to have a great future. You see, there is no point in creating software that is not tested properly in the first place because that will be a huge turn-off for your valuable audiences.
Not just the software industry, but every business now seems to have become thoroughly aware of this risk and are finally considering offering more prominence to software testers than they used to be, so in a way, if you are planning to make a career as a software tester, the best time is now!
Both testers and developers are extremely important, and is more crucial for them to work in tandem for any software development project to succeed. Unfortunately, many of you have this misconception that software development is way more important than software testing. Well, that’s certainly not the case!
Whenever you are conducting a development project, please bear in mind that you will require two pillars or fundamentals, called development and testing, and like it or not, they cannot be separated from each other because choosing either of them can leave you with great issues. In addition, the point when everything begins, you need both teams working in sync right from day 1. If your project involves blockchain-based finance, partnering with a reliable DeFi application development company early ensures robust architecture and testability across the stack.
What’s more to ask for? It is also very important to know that software testing is an extremely energising activity. Those who are working for the first time on the software development project might think of this as quite exhausting, daunting, and overwhelming. But trust me when I say this, you no longer need to be bothered with any specialised skill to be great at it.
The end goal or ultimate objective for a software tester is to successfully detect a few errors and endeavour to successfully recreate them. Remember, tapping a few buttons or crossing your fingers for a bug won’t be enough.
Till now, software testing has been known for a poor knack, but times have changed. Now, software testing as a career seems pretty fulfilling, fun, and challenging; no wonder more and more people are trending towards this profession.
Who is a software Tester?
He is mainly responsible for evaluating a software application entirely to spot major issues, bugs, and all missing requirements. In short, the developed software needs to perform well, irrespective of any and every situation. So, are you prepared for the upcoming interview? Do you really want to nail this one? Well, it’s time for some smart work.
Well, as you can see, this is basically an interview preparation guide where you will come across some of the top software testing interview questions which are definitely asked irrespective of your experience level, whether you are a beginner, an intermediate, or a well-experienced one.
Frequently Asked Software Testing Interview Questions and Answers
1. What is the significance of software testing?
Well, inadequate software testing techniques or not conducting software testing have led to several noticeable failures. Plus, software testing offers a wide range of benefits such as early detection of errors, streamlined workflow, preventing expensive mistakes from happening, ensuring software reliability, which means irrespective of the time taken, you are bound to receive a product offering accurate, consistent performance. In addition, software testing ensures data security, which means there is no chance for unauthorised access or data breaches.
Also, when done in the proper manner, software testing turns out to be pretty intuitive and does exceed the end users’ expectations, eventually leading to an increase in user retention.
What else, a well-tested software means you are developing a solid brand where you are bound to receive high-quality products and nothing less. And most important of all, the chances are miscommunication are pretty low here.
2. Can you share different types of software testing?
There is no cookie-cutter way when it comes to testing software, and so are its types. Software testing can be categorised into two domains:
- Manual Testing
- Automation Testing
Manual testing is a technique where the testing is carried out by a professional who may or may not have programming knowledge, since black box testing is easy to learn and get started with. Also, it is less expensive, not to mention the technique features where the tester writes scripts, and all these tests are successfully run on machines or automation tools.
Manual testing is done in three ways:
- White box Testing – In this particular technique, the internal structure is successfully tested. Here, the correctness is verified. Some of the types of white box testing include – path testing, loop testing, unit testing, mutation testing, Integration Testing, penetration testing, etc.
- Black Box testing – Here, the tester isn’t concerned with the internal knowledge or implementation details of the software, but what he needs to take into consideration is the overall validation of the functionality, depending on pre-given requirements. Some of its types include – functional testing (unit testing, integration testing, system testing), non-functional testing (performance testing, usability testing, compatibility testing), regression testing, etc.
- Gray box testing – Here, you will find a rare combination of black box and white box testing, so here everything is taken into featuring internal data structures and algorithms. This type is mainly done from the user perspective and requires high programming skills, and of course, this type is non-intrusive. Some of the examples to consider here include matrix testing, pattern testing, Orthogonal Array Testing, Regression testing, state transition testing, data flow testing, etc.
3. What is STLC?
Software Testing LifeCycle is an important process where it is possible to conduct step-by-step testing so that you can verify whether the developed software is able to meet the pre-defined needs. Software Testing Lifecycle incorporates mainly six phases:
- Requirement analysis – Here, the testing team is supposed to study all the pre-given requirements to spot testable concerns, and the key is that all these requirements can be functional as well as non-functional.
- Test planning – The next stage is to plan the tests. A test plan strategy is developed, featuring everything from cost estimates to what efforts need to be taken for the success of the project. Here, aspects such as test environment, test schedule, and test limitations are taken into consideration.
- Test case development – The next phase of STLC features creation, verification, and rework among all test cases, and this stage is considered once the test plan is ready.
- Test Environment Setup – Now, in this particular phase, hardware and software conditions are checked. So, here the software tester has to understand the environment setup and determine the hardware and software requirements.
- Test Execution – In the next phase, the testers are supposed to carry out the testing on the basis of pre-determined test plans and test cases. All the bugs reported are thoroughly taken care of or reverted to the development teams for proper correction. And then retesting is done.
- Test Closure – The last phase of the software testing lifecycle, where test execution is done, featuring test completion reporting and collection of test results.
These were pretty basic, time to up the game a bit!
4. Can you explain a user story?
Developing software is not an easy venture; it needs all the pre-determined requirements to be successfully fulfilled. Now with the ever-evolving changing needs, the software must implement proper features, and that is where the user story is included:
- As the name implies, it successfully describes the type of user; what the user needs and wants, and of course, the why part.
- It assists in creating a simplified description of the requirement
- It includes successful recording on index cards, on post-it notes, as well as project management software.
- User stories might be written by a wide range of stakeholders, including clients, users, managers, or development team members.
- Here you are bound to receive a user-focused framework to take care of all day-to-day work.
5. Explain cookie testing?
It is a kind of software testing that successfully checks the cookie developed within the web browser. All the user-related information that can be used to successfully track users is stored in the cookie. So you can easily learn where the users are heading, and cookies are highly recommended to establish successful communication between numerous web pages. Also, cookies can assist in avoiding unwanted security threats.
6. What is Shift Left Testing?
When the testing is done pretty early in the development process, mainly to catch bugs, it is known as shift left testing; however, this type of testing is done to reduce the cost and make relevant efforts to fix issues that might turn into a huge snowball later. Some core activities here included are – Static testing, unit testing, and continuous integration testing
Shift left is pretty different from shift right. This type of testing involves real user feedback to find relevant issues, enhance overall quality, and even plan new features if needed. Some core activities here included are – Exploratory testing, usability testing, monitoring, and feedback analysis.
Moreover, shift left testing is done to detect issues early, whereas shift right testing is done to spot issues, especially in production and real-world scenarios. However, both types of testing scenarios include absolute improvement and enhancement.
7. Explain the defect age
Now there is always some difference between the time when the defect was first detected and what is the scenario now, however, the defect is still in the open state. Now this can be bifurcated into two parameters:
- The defect phase, which is ideologically a numerical value mainly assigned to a defect that keeps occurring at any phase, depending on the risk involved within the defect.
- The next parameter is defect age time, where you need to understand date of defect detection is not the same as the ultimate time when the defect is open or hasn’t been resolved.
8. What is test closure?
Test closure is a document featuring all types of tests that are covered in the software development lifecycle.
Test closure comprises a wide range of activities, including test completion reports, test completion matrix, a summary of test results, etc. Not just that, here other teams get to learn about the end of the testing process.
You are bound to receive a complete report of all the errors and the way they have been resolved; in fact, it is possible to locate the source of the error as well.
9. Can you explain a bug report?
The ultimate objective of software testing is to catch bugs and rectify them that are present or that might be present once the software is launched. So during the testing cycle, a tester is supposed to record all the observations and other relevant information used for conducting a successful development project. This test record can be called a bug report. So this report usually assists team members to:
- Understand the problem
- What needs to be done next
- What was the environment when these defects or bugs occurred?
- The resolution.
In addition, a bug report needs to comprise the defect/bug name, defect/bug ID, defect description, severity, whom is reported it by, when it was reported, all the detailed steps included, who fixed the defect, and, of course, the date closed.
10. What is risk-based testing?
Risk-based testing mainly incorporates assessing all kinds of risks. The ultimate purpose of risk testing includes,
- Spotting risks to system quality
- Using the knowledge of risk to guide all testing planning, specifications, preparations and seamless execution.
- Risk-based testing features mitigation and contingency.
And lastly, what do you think of incorporating AI in quality assurance?
Well, incorporating AI in quality assurance offers a wide range of benefits: it accelerates release cycles by automating repetitive testing tasks, reduces unnecessary costs, improves risk management, helps ensure regulatory compliance, and supports high scalability and robustness for complex enterprise applications. Using LLM for developers can further speed test-case generation, create clear bug descriptions, and assist in writing automation scripts, making QA more efficient and accessible.
Other Relevant Questions to Ponder
In addition to these, you might be asked questions to examine your behaviour or office etiquette, such as:
- If you face any difficulty in the project, how will you deal with it?
- Have you been in a situation where you had to face an external team to deliver a project on time?
- How do you handle feedback and criticism?
- What do you know about the latest technologies and trends?
- Have you managed a leadership role? Can you elaborate more on the outcome?
