How to Write Test Cases for Software: Examples & Tutorial

The 20 Best Software Tester Interview Questions

1) How well do you handle ambiguity?Test cases are not always straight-forward and QA Engineers will need to act on their personal judgement. They need to feel comfortable with ambiguity.

2) What is your mentality toward automating tests that are currently being done manually?Automating test cases brings numerous benefits. Automation saves time and reduces human error. QA engineers should recognize the value in automation.

3) Explain how you distinguish a symptom vs. a cause when testing.Often times within the QA process, test cases fail. But why are they failing? This can be tricky. A great QA engineer is able to provide exact reasons to the developer, rather than simply saying a test case failed.

4) Do you feel comfortable standing up to developers who disagree with your results?In some situations, reporting failures can be a delicate process. Perhaps a developer spent a lot of time on some code which does not exactly meet specifications. QA engineers need to be able to stand up for what they know is right.

5) Are you willing to cut corners to save time?The correct answer is NO. All test cases need to be run, and making assumptions frequently leads to issues down the road.

6) Can you explain the SDLC and Agile methodology?QA engineers must understand their role and where it fits into the ecosystem.

    How Many Test Cases We Can Write In A Day

    We can tell anywhere between 2-5 test cases.

    • First test case â 1st day, 2nd day.
    • Second test case â 3rd day, 4th day.
    • Forth test case â 5th day.
    • 9-10 test cases â 19th day.

    Primarily, we use to write 2-5 test cases, but in future stages we write around 6-7 because, at that time, we have the better product knowledge, we start re-using the test cases, and the experience on the product.

    Are There Specific Tools You Use For Testing If So How Do You Choose Which Tools To Use

    Technical Interview Questions

    The interviewer is trying to get a better sense of how you work and which tools you use when you do. Take this opportunity to demonstrate your skills as an automation tester and provide the interviewer with real-life examples.

    Example: “The first thing I do is determine which tests I want to run on cases. From there, I can decide which tools I want to use by researching which ones support the requirements of my project. I also look at my employer’s budget and which resources we have at our disposal. There are some tools I prefer using, however, I’m open to any tool and often research new tools when beginning automation testing. My overall goal is to find tools that perform the tests I need them to within my company’s budget.”

    What Is Defects In Software Testing

    The term defect refers to a system error that prevents the intended action from being accomplished. Testing is most important when it comes to finding defects. Testing needs to begin early in the development process since defects can be found throughout. As shown in the following figure, defects are divided into three main categories:

    • Wrong: It implies incorrect implementation of requirements. There is a variance between the specifications and what was expected, resulting in this defect.
    • Missing: This indicates that a specification has not been implemented, or a requirement of the customer has not been properly noted.
    • Extra: In this case, the defect is caused by a requirement incorporated into the product that was not provided by the end-user.

    What Is A Bug In Software Testing

    A software bug is an error in the software that produces wrong results. A software tester tests the software to find bugs in it.

    There are many causes for the bugsfor example, poor design, sloppy programming, lack of version control, or miscommunication. Throughout development, developers introduce hundreds or thousands of bugs in the system. The goal of the tester is to uncover those bugs.

    You can find a bug in many different ways, regardless of your role. When building the software, the software developer might notice the bug in another module, written by another developer or by themselves. The tester actively tries to find the bugs as part of a routine testing process. Finally, the users could see the bugs when the software is in production.

    All bugs, no matter how they are found, are recorded into a bug-tracking system. A triage team triages the bugs and assigns a priority to the bug, and assigns the bug to a software developer to fix it. Once the developer resolves the problem, they check in the code and mark that bug as ready for testing. Once a bug is ready for testing, it goes to the tester, who tests the software to verify if its indeed fixed. If it is, then its closed. If not, they assign it to the same developer with a description of the exact steps to reproduce the bug. Some examples of popular bug-tracking systems include BugZilla, FogBugz, etc.

    Trivia:

    Practice With A Friend

    Capgemini Interview Experience 2021 for Software Testers | Capgemini Technical & HR Round Questions

    How Do You Write A Test Case

    Of course you want someone who can write a test case as easily as they can drink quarantinis. But not every interviewee gets an A+ and a gold star, particularly those who are new to a software testing career.

    Donât expect the applicant to have the answer, Bulyhin says. But the discussion can show what the interviewee considers important. âYou should see attentiveness, clear articulation of thoughts, and how comfortable they would be when working.â

    It isnât their answers that matter as much as their questions. âWhat I look for here is for the potential QA tester to ask a question,â says Shayne Sherman, CEO of TechLoris. âI want them to ask what platforms we support. Anyone who has done any QA on web applications knows that there are significant differences between the different browsers and devices. QA shouldn’t sign off on any test case until it has been tested on all device/OS/Browser combinations.â

    So even if QA newbies flub that part of the interview, they might still walk away with an offer…as long as they flub it the right way.

    How Much Testing Is Considered Sufficient

    It is impossible to exhaustively test an application. Testers need to pick test cases that the most likely to test the apparent vulnerabilities of the code. In order to stay efficient, the focus on testing should be on common problem areas and important features and functionality.

    The interviewee should be able to define a good balance between exhaustive and efficient testing. Itâs essential to acknowledge that the testing process needs to have a definitely end goal.

    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.

    How Does Stress Testing Differ From Load Testing

    Manual Testing Interview Questions and Answers

    Stress testing involves raising the load on the system is increased beyond the normal, expected range. Load testing, on the other hand, testing that involves a steady, consistently high load which is still within expectations.

    While this is a subtle difference, the interviewee should be able to spell out possible scenarios where each approach might be useful and what each method of testing might be used to diagnose.

    What Is An Associate Level Engineer Interview Like

    As an interviewer, I often see associate level engineers who havent quite found their footing yet. They understand the concept of QA and that it entails testing, but there are so many different types of testing available.

    If an associate level engineer candidate doesnt enrich their knowledge with different methodologies in testing , this makes them a less appealing candidate. To me, this is just part of being prepared for an interview and understanding the field that is software QA.
