Quality Assurance: An Overview
Quality Assurance is analyzing the quality of the products, software, or goods that a company manufactures. A quality analyst’s role is crucial because the reputation of the brand depends upon his work. Therefore, it is essential to examine the products carefully before they reach the market. A bad product will surely bring a disgrace to the company. Therefore, such products must be either rejected or improved. It is also important to meet the requirements of the customer at the same time. In precise, Looking at the product from the customer’s perspective and understanding its competitive interest assists with qualitative analysis. Today, we’ll see some of the TRICKY QA Interview Questions with Simple Answers
Basic Understanding of Quality Assurance
The difference between qualitative and quantitative strategies is related to the distinction between human and modern science. Quantitative interpretation uses specific facts such as profit and loss ratios, earnings, and so on. These can be secured into a programmed model to generate an exact result, such as the stock’s fair value or an estimate for income growth. At present, humans have to manually give inputs to the program that processes these values, followed by a fair point of subjective knowledge. Once they are computerized, though, machines can deliver quantitative study in a few seconds, thereby saving a lot of time. On the other hand, it might take even the most skilled and knowledgeable humans minutes or hours.
Whereas, Qualitative analysis deals with hypothetical, inaccurate companies that belong to the social and informative realm rather than the technical side. This method depends on the knowledge that computers currently lack since issues like accurate relationships with a brand, management honesty, customer fulfillment, competitive dominance, and cultural variations are tough, arguably impracticable, to achieve with mathematical inputs.
Here are some of the sample questions to crack your interview for a quality analyst.
Sample Tricky QA nterview Questions with Simple Answers
- Are our quality assurance and software testing the same? How?
Most of us get confused with these terms. So, quality assurance is monitoring and examining the entire process of software making. Any changes and customizations are carried out based on the customer’s request. Whereas software testing ensures the performance and the usability of the final output before handing it over to the customer.
- What do you mean by Testware?
The accessories that are designed during the testing process which are needed to design, layout, and perform experiments are called Testware. Testware comprises documentation, texts, data, required results, set-up, and pack-up procedures, folders, database, working conditions, and any supplementary software or services used in testing. Generally, Testware is also described as a Testing tool. Also, it is a conventional manner that test wire should be placed under the direction of a management tool and save accurately.
- What are the challenges that the Software Quality Assurance team would face while testing?
- Supernatural Expectations for Automated Testing
- Utilizing the Wrong Tools
- Automating unwanted Tests and Leaving out the Important Test Cases
- Picking the Wrong Testing Time
- The necessity of Proper Testing
- What is data-driven testing?
Data-driven testing is a computerization testing structure, which tests the various input data on the AUT. These values are read instantly from the data registers. The data files may incorporate CSV files, excel lists, data provisions, and much more.
- Explain the steps for the Bug Cycle?
- Once the fault is recognized by the tester, it is allocated to the development supervisor in open status
- If the bug is a real defect the improvement team will correct it.
- If it is not a proven defect, the error will be overlooked and considered rejected
- The following step will be to examine whether it is in scope. If the bug is not part of the contemporary release then the errors are delayed
- If the defect or bug is proposed prior then a DUPLICATE status will be allocated by the team.
- When a bug is designated to a developer to fix, an IN-PROGRESS status is given
- Once the defect is corrected, the status will switch to FIXED. At the closure, the tester will give a CLOSED update if it passes the terminal test.
- To which extent should Testers do their testing or do you believe testing is the obligation of the QA team?
The answer to this question varies based on the company environment you work in. In today’s developing test scenario, it is also the developer’s efficiency to achieve some of his software testings. However, it is not expected that he will have the potential or that his concentration should be to work through comprehensive analysis plans or tests on a huge pile of devices. However, without the burden to evaluate and test his code, an insight of ownership or possession will not happen. Therefore, we consider that results will grow if all parties have admittance to test cases and can control and obtain them regularly to check if the newest changes made any regression.
- Differentiate Matrix & Metrics? Any examples?
- Metrics: A scale for estimation, we can’t manage anything which we can’t measure – i.e. no. of bugs identified, the sum of test cases completed, execution potency, and test achievement % age – anything that can be displayed numerically or % age, commonly to trace execution and take remedial steps if needed)!
- Matrix: Remember the mathematical theory you studied at school? Implementing it to Software Testing – ‘Matrix’ is nothing but a structural representation of the correlation and relation between rows & columns. Now, what would a Test team want to describe? A simplistic case would be ‘Necessity Traceability Matrix’ – Specifications >> Test conditions >> Test events >> Performance state >> Bugs. & why practice RTM? Simple, to estimate Coverage w.r.t. customers’ conditions – every element has to be tested & every error has to be resolved successfully.
- What are the various stages of the Software Testing Life Cycle (STLC)?
‘To make it Correct, first, recognize what’s the Mistake – but how? How do you distinguish the error? Foreknowledge says – Provide me the purpose, and I can spot what’s the defect, right? Nah! We are not operators. We are software specialists. How do you strengthen customer’s trust with your ad-hoc analyses? After all, the customer is rewarding you for getting the job done. And they need ‘Quantitative’ papers & a ‘Quality’ outcome at the end. So how do you make sure that your customer is satisfied? Ignore ‘Software Testing’ – in any industrial background, how do you know that your Consumer is super-pleased at the end?
Lifecycle is in how a stock or method advances to maturation, from origin to the outcome. And at each phase, you have the customer updated on the development and improvements through a collection of deliverables.
- Contrast and explain Performance, Load, Stress, and Volume Testing?
- Performance Testing – The intention is not functional but to reveal enforcement issues such as network lag, data execution, database performance processing, pressure maintenance between servers, acknowledgment time, etc. (agility and effectiveness of the system). Performance includes Load, Pressure & Quantity testing.
- Testing the Load – Testing the ‘capacity of the application’ is called load testing. Still not clear? The familiar situation in most of the IT corporations – the firm’s portal cannot be reached as soon as you get the message that appraisal reports have been released. The website couldn’t handle the employers’ rush or simultaneous entrance to the system. The intention is to investigate the performance of the software under average and over trafficking conditions – at what time the system’s acknowledgment time diminishes or fails.
- Pressure Testing – We get stressed when we can’t handle the stress. We can handle the pressure to a certain limit not but beyond it. Similarly, the software can handle only a certain load, exceeding that it breaks. The goal of ‘Stress Testing’ is to examine the software under unusual load conditions (surpassing the regular limit) and then its execution is watched to scrutinize how the software would act at the breakpoint. There are several ways to create abnormal circumstances – the database can be switched off and on, complicated database queries, constant input to the system, network portals can be shut down or restarted alternatively.
- Volume Testing – Volume testing is carried out to observe the reactive nature of the software with various dimensions of the information being transferred or to be processed. E.g. If you are testing Microsoft word, volume testing would guarantee if the file can open, save and work on files of different word documents
- What do you mean by Functional & Non-functional testing? OR What are the different types of Software Testing?
Broadly, Software Testing Types can be differentiated into two types Functional or Non-functional, i.e., you need to verify the functional features like functions, adaptability, user interface, etc. But, instead, you want to approve the execution, defense aspects.
- Functional Testing – It is the most essential Test type, Functional testing concentrates on testing the software with the design reports, use cases, and conditional documents – that it accurately delivers all its expected functions.
- Non-Functional Testing – Here, you are not examining the software’s functionality. Instead, the focus is on non-functional features like appearance, capacity, performance, accessibility, localization, warranty, security, restoration, etc.
I hope You would have got a clear view of quality assurance and software testing. So, prepare well and All the Best for your interview!!
