Tell Me About A Time You Missed A Bug

Test Automation Engineer Interview Questions-Entry Level

In the very first question I told you to unselfconsciously put your best foot forward. This is why. Not every question is going to be phrased in a way that puts you in the best light.

In a QA interview the person tasked with hiring needs to know that any potential team members are open about making mistakes.

The worst thing a QA tester can do is act as if theyve never made an error. Be open and honest. By the time youre sitting in an interview, its a certainty that youve missed a bug or made a mistake. Talk them through the mistakes you made, how you resolved the problem, and what youve learned from it.

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.

Role And Responsibilities Of Test Engineers

So what exactly do test engineers do? In the simplest terms, test engineers create and run quality assurance operations on products or systems to confirm that they function properly and meet the needs of the final audience. Test engineers also run case-scenarios to determine what problems could arise during the use of the product or system and how these issues can be addressed. The goal is to iron out as many bugs as possible, resulting in a high-quality commodity.

Specific job responsibilities of test engineers may include:

  • Testing various aspects of the product or system, such as function, performance, regression, and service
  • Designing test environments, test plans, test cases and usage scenarios, and executing these operations
  • Providing feedback on useability and serviceability

Senior test engineer duties include:

  • Developing tests and designing hardware or software to execute said tests
  • Verifying and validating new tests, test systems, and solutions
  • Performing automated and manual tests and interpreting test results
  • Creating, updating, and communicating documentation of tests performed
  • Providing technical expertise and design input

Technical understanding and experience are requisites of this position, but test engineers must have other soft skills to perform their roles successfully. These include:

How Do You Automate The Testing Of Captcha

CAPTCHA testing cannot be automated which is the core objective of every effective CAPTCHA technique. By definition, it cannot be automated by a computer. If it could, then it is not a suitable challenge for your application.

If, however, you need to test a CAPTCHA-enabled application, you must collaborate with the development team to provide a workaround or back door that enables the automated test to pass the CAPTCHA test. It is critical to use this alternative only in a test environment and not in production.

Which Test Cases Are Written First: White Boxes Or Black Boxes

Is test automation a good career to take?

Usually, black box test cases are written first and white box test cases later. To write black box test cases we need the requirement document and, design or project plan. These documents are easily available at the initial start of the project. White box test cases cannot be started in the initial phase of the project because they need more architecture clarity which is not available at the start of the project. So normally white box test cases are written after black box test cases are written.

What Would You Include In An Automation Test Plan

Since building a plan for automation testing is a big undertaking, you dont have to go into every detail.

Instead, name a few important aspects of a test planfor example, talk about how the plan should describe how the tests will be designed, how they will be executed, how defects will be managed, and what the test automation reporting will look like.

What Are The Selenium Suite Components

Selenium IDE

It is a Firefox/Chrome plug-in that was developed to speed up the creation of automation scripts. It records the user actions on the web browser and exports them as a reusable script.

Selenium Remote Control

RC is a server that allows users to write application tests in various programming languages. The commands from the test script are accepted by this server and are sent to the browser as Selenium core JavaScript commands. The browser then behaves accordingly.

Selenium WebDriver

WebDriver is a programming interface that helps create and run test cases. It makes provision to act on web elements. Unlike RC, WebDriver does not require an additional server and interacts natively with the browser applications.

Selenium Grid

The grid was designed to distribute commands to different machines simultaneously. It allows the parallel execution of tests on different browsers and different operating systems. It is exceptionally flexible and is integrated with other suite components for simultaneous execution.

    What Are The Different Models Available In Sdlc

    There are various models available in software testing, which are the following:

    • Waterfall model
    It is shallow, wide and scripted testing. It is narrow and deep and unscripted testing A dry run testing is a process where the effects of a possible failure are internally mitigated.
    When the builds come, we will write the automation script and execute the scripts. So it will perform automatically. It will perform manually. For Example, An aerospace company may conduct a Dry run of a takeoff using a new aircraft and a runway before the first test flight.
    It will take all the essential features and perform high-level testing. It will take some significant features and perform in-depth testing.

    You dont need to be an incredible wunderkind or world-famous expert to prove your worth to a potential employer. Many times, an employer wants someone who fits the team and is willing to apply themselves even if they dont tick all the boxes for a position.

    A willingness to grow, learn, and push themselves is the best quality for QA job candidates. Its fine if this particular position may only be a stepping stone for your career, but dont let your interviewer know this.

    The company is about to invest thousands of dollars into you. Dont start off with I think this is where I want to be. Youll never get hired that way. I myself wasnt sure I was going to stay in QA, but here I am15 years later and Im still in this field. You never know what the future holds, so be confident and give this field a shot since you never know what can happen once youre in it.

    Ques19 What Are The Reasons One Will Refrain From Automation Testing

    Ans. Some of the common disadvantages of automation testing are-

  • Might prove expensive. The cost of automation tools is quite high.
  • Testing of UI or UX of the application is difficult.
  • It takes a lot of time to write exhaustive test scripts.
  • Requires a team of professionally trained and skilled engineers.
  • What Is The Difference Between Static And Dynamic Testing

    Static testing Dynamic testing
    Static testing is a white box testing technique which is done at the initial stage of the software development lifecycle. Dynamic testing is a testing process which is done at the later stage of the software development lifecycle.
    Static testing is performed before the code deployment. Dynamic testing is performed after the code deployment.
    It is implemented at the verification stage. It is implemented at the validation stage.
    Execution of code is not done during this type of testing. Execution of code is necessary for the dynamic testing.
    In the case of static testing, the checklist is made for the testing process. In the case of dynamic testing, test cases are executed.

    What Are The Testing Types Supported By Selenium

    some software testing questions for interview

    Selenium supports Regression testing and Functional testing.

    Regression testing – It is a full or partial selection of already executed test cases that are re-executed to ensure existing functionalities work fine.

    The steps involved are –

  • Re-testing: All tests in the existing test suite are executed. It proves to be very expensive and time-consuming.
  • Regression test selection: Tests are classified as feature tests, integration tests, and the end to end tests. In this step, some of the tests are selected.
  • Prioritization of test cases: The selected test cases are prioritized based on business impact and critical functionalities.
  • Functional testing – Functional Testing involves the verification of every function of the application with the required specification.

    The following are the steps involved:

  • Identify test input
  • Compare the test outcome with the actual outcome

    What Are The Different Components Of Selenium

    Selenium is not a single tool or a framework. It is a suite of tools that work with each other or in isolation to provide different types of automation testing. Here are the four major components of Selenium.

    • Selenium WebDriver
    • A collection of open-source APIs and browser-controlling code implementations that provide a concise and straightforward programming interface. More Details.
  • It enables the tester to run multiple tests across different browsers, machines, and operating systems in parallel.
  • How Do You Choose A Tool/framework For Automated Testing

    To perform any automation testing, you need to rely on software tools or frameworks. There are plenty of options to choose from many alternatives.

    Here are some criteria based on which one can evaluate these tools.

    • Programmable or code-less tools. Some tools require programming skills, while some dont, allowing a non-coder tester to create test cases with visual assistance. Depending on your teams experience and skill-set, you should choose accordingly.
    • Commercial vs. Open Source. Theres a vast variety in the pricing of the tools based on the feature they have. Commercial tools can be expensive, but you get tech support when needed. Open-source software is free, but you have to do your research when troubleshooting the problems.
    • Ease of use. Some automated testing tools are notoriously hard to use and require extensive training before providing any value. Some are easy to use, and you can start using them out-of-box.

    Some of the most popular automation tools include Selenium, Katalon Studio, UFT, TestComplete, Testim, etc., and many more. When choosing one, you should consider the testing requirements for your project, consult your team, and assess their skills, experience, and comfort with the tool.

    You should also periodically assess the return on investment from the tool you choose and be prepared to switch if needed.
