What Is Automated Testing

How To Prepare For A QA Test Automation Interview

As the name suggests, automated testing, which is also called test automation, is the programmatic execution of the tests. The tester uses an automation tool or software like Selenium to write code that performs the following tasks.

  • Automatically run the software.
  • Feed the input data to the system.
  • Examine the output with the expected outcome.
  • Fail the test if the results dont match. Otherwise, pass the test.
  • Once a test is automated, you can run it as often as you want, to check if any new code has broken it. It enables you to spend your time on other high-value tests, such as exploratory testing that help find bugs that an automated test would miss.

    Automated testing is beneficial for repetitive testing with inputs that dont change frequently. Humans get tired and bored from conducting the same tests repeatedly and seeing the same results. Its easy to make mistakes when you are testing a feature for the twentieth time. Software is much better at doing repetitive tasks without getting tired or making mistakes than a human operator would.

    Quality Assurance Interview Questions & Answers

    Quality assurance is an important department within companies across a variety of industries. Whether you are working in computers and software, customer service, or health care, there is usually an assigned team of people who ensures that customers receive quality service and products that meet their needs. There are questions that many quality assurance hiring managers might ask to potential candidates to determine their skill levels and past experiences, and how these factors will affect their performances in new positions.

    How Would You Manage A Testing Issue

    This question attempts to uncover how you might handle problems during your testing. The interviewer might like to hear about how you manage issues with the software test itself. Explain to the interviewer what your general steps would include before asking your supervisor.

    Example:”Depending on the issue, I would rerun my test to ensure the testing was being implemented correctly. If the problem persisted, I would restart the software and testing environment to make sure everything was working on the testing side. If problems persisted after a couple of minutes, I would talk to my supervisor or manager so I could manage my time wisely.”

    In my writing experience, I have found several defects. Some of them were small whereas some of them were huge. The biggest one I have encountered so far is in the previous project on a page where I found a button called âMore Informationâ.

    Once the person using the computer pressed that button, a new window would automatically pop up. I would then close the window by using three ways. First I would click on âXâ located on the top right corner of the page.

    I would then click on the Close button and finally the combination keys on the keyboard.

    What Do You Mean By Test Case

    Test case is basically a document that includes a set of test data, preconditions, expected results, and postconditions. This document is specially developed for a specific test scenario to ensure whether the software product meets the specific requirement or not. In manual testing, test cases are executed manually by a tester without using any of the automated tools. One can easily identify loopholes in the specifications while developing test cases.

    What Did You Do In Your Last Project

    For these last four questions, there are no clear answers, only guidelines. The biggest piece of advice I can give is to answer as honestly as possible. Dont exaggerate or undervalue your contribution in previous teams. Tell them what your day-to-day role was, what tools you used and how the QA testing went.

    What Are Functional Test Cases And Non

    • Functional testing: It is testing the functionality of a software or an application under test. It tests the behavior of the software under test. Based on the requirement of the client, a document called a software specification or requirement specification is used as a guide to test the application.
    • Non-functional testing: In software terms, when an application works as per the users expectation, smoothly and efficiently under any condition, then it is stated as a reliable application. Based on quality, it is very critical to test these parameters. This type of testing is called non-functional testing.

    Explain The Difference Between Validation And Verification

    The interviewer may ask this question to understand if you know the difference between these two critical processes QA engineers use while testing a software’s quality and performance. You can briefly explain the two processes. Try to include technical details to highlight your knowledge and experience.

    Example:”Verification and validation are two independent processes. Verification is the evaluation process that happens during the development phase to determine if that phase meets the specified requirements. Validation is the evaluation process that is conducted when the team completes development. It helps to determine if the product meets the specified requirements.”

    How To Prepare For Such Tasks

    Qa Engineer: Who They Are And What They Do

    A Quality Assurance Engineer is a specialist who performs functional testing of software at all stages of development. To better understand what kind of specialist your company needs, you need to understand the terminology. A lot of people mistakenly think that the terms Quality Assurance, Quality Control, and Testing are synonymous, but this is a wrong opinion. Let’s see what is the difference among them.

    ⢠Quality Assurance: QA specialists prepare and set standards, analyze quality, select tools, prevent mistakes, and improve the program.

    Today, everyone prefers developers who use HTML elements for their intended purpose in order to fix bugs in the future .

    Not only the developer’s ability to write without using tables is appreciated, but also the real adherence to this concept. Habit is a dangerous thing that can still lead to obsolete use of tables.

    ⢠Quality Control: product quality control specialists are responsible for analyzing test results, finding and eliminating bugs. QC specialists review code, conduct technical reviews, and validate the program.

    ⢠Software Testing: testers check the finished product for compliance with the established requirements.

    What should a QA engineer be able to do? In a perfect world, a highly qualified QA engineer should have the following theoretical knowledge and practical skills:

    What Are The Categories Of Defects

    There are three main categories of defects as shown in the below figure:

    • Wrong: It implies that requirements have been implemented incorrectly. It is a variance from the given specification.
    • Missing: This is a variance from the specifications, an indication that a specification was not implemented, or a requirement of the customer was not noted properly.
    • Extra: It is a requirement incorporated into the product that was not given by the end customer. It is always a variance from the specification but may be an attribute desired by the user of the product.

    What Is The Difference Between Severity And Priority

    Answer: These are important distinctions that must be known for proper time management. Severity is how difficult the issue is to fix. Priority is how important the issue is to fix.

    Just because an issue is high severity doesnt necessarily mean its high priority and vise versa.

    Heres an example of a high severity, low priority issue:

    • The application crashes when a rarely used function is run on legacy software that most users cant access.

    Heres an example of a low severity, high priority issue:

    • The wrong company logo is displayed on startup.

    What Are Training And Testing Accuracy

    Preparing for the QA Interview

    Software testing allows you to verify any system so that you can identify any sort of gaps, errors, and missing client requirements. It is done with the help of several methods and models that allow you to check and test the software in each and every step from its development to its execution. In simple terms, software testing is the process in which you find errors in any given software program or application such that the application functions as per the requirements of the end-user. Testing can be classified into two major categories: Functional testing and non-functional testing.

    Training accuracy and testing accuracy are two ways in which the accuracy of the software can be tested. With the help of these tests, you can monitor the working, accuracy, and ability of the given software and also check if the requirements of the clients are met. In general, the training accuracy is the accuracy that you attain after applying the given model on the available training data, whereas in testing accuracy, the accuracy you receive is for the testing data. These are extremely helpful when you need to compare the results to identify overtraining.

    Does Tdd Guarantee A Bug

    With the advent of the more Agile concepts like Extreme Programming , Paired Programming and Test-Driven Development , we found ways to build software better, faster and cheaper.

    All these methodologies have simple goals to speed up development, to discover major bugs earlier, and build a lot more product and faster than is possible with other methodologies. Extreme Programming, Paired Programming, Test-Driven Development and the likes do not give you a release-ready product. Release-worthy, yes, but Release-ready, No.

    You need a level of testing to make a product release-ready. By their very nature of focusing on the critical bugs, extreme Agile methodologies wont give you this assurance.

    What Is The Difference Between Load Testing Volume Testing And Stress Testing

    There are many types of software testing, and these three types of testing are the most common among software testers and quality assurance engineers. Your answer will show the interviewer that you have legitimate experience in multiple types of software testing and understand the difference between them all.

    Example:”Load testing is when you test the software under a heavier load that is still in the expected range, whereas stress testing is when you test the software under a much heavier load that goes outside the expected range. Volume testing is just a system check to find out if the software can manage the expected data or requests.”

    What Are The Different Verification Techniques You Know

    Especially when interviewing for a QA lead job, youll need to display your variety of knowledge. Verification and validation both fall into the quality control category, but there are four widely regarded methods in use today.

  • Inspection. A noninvasive look into a system or item that may include measurements and/or physical manipulation.
  • Demonstration. This method involves using an item or system in an intended manner to produce the expected results.
  • Test. Similar to demonstration, test verification narrows the focus and what results should return using specific requirements, inputs, or data.
  • Analysis. System models, testing equipment like static analysis tools, and calculations all factor into this verification method. This option can be used to identify weak points that could cause issues in the future.
  • Best Practices for Using Static Analysis Tools
