What Is A User Story

Top 40 Test Automation Interview Questions | Software Testing Interview Preparation | Edureka

All software has a target user. A user story describes the user’s motivations and what they are trying to accomplish by using the software. Finally, it shows how the user uses the application. It ignores the design and implementation details.

A user story aims to focus on the value provided to the end-user instead of the exact inputs they might enter and the expected output.

In a user story, the tester creates user personas with real names and characteristics and tries to simulate a real-life interaction with the software. A user story often helps fish out hidden problems that are often not revealed by more formal testing processes.

What Is Component Testing

Component testing, also known as unit, module, and program testing, searches for defects in and verifies the functioning of software that are separately testable. Component testing may be done in isolation from the rest of the system depending on the context of the development life cycle and the system. Most often stubs and drivers are used to replace the missing software and simulate the interface between the software components simply. A stub is called from the software component to be tested a driver calls a component to be tested.

How Will You Conquer The Challenges That Occurred Because Of The Unavailability Of Documents During The Testing

Ans: In case the standard documents, such as Feature Description Document or System Requirement Specification are missing, then quality assurance will be based upon the following references, such as:

  • A previous version of the application

Another method could be having discussions with developers and business analysts. It will help resolve doubts and open a channel for bringing transparency to the requirements.

What Are The Different Methods Of Testing

There are three methods of software testing and they are as follows:

  • Black-box testing: It is a testing strategy based solely on requirements and specifications. In this strategy, it requires no knowledge of internal paths, structures, or implementation of the software being tested.
  • White box testing: It is a testing strategy based on internal paths, code structures, and implementation of the software being tested. White box testing generally requires detailed programming skills.
  • Gray box testing: It is a strategy for software debugging in which the tester has limited knowledge of the internal details of the program.

Fund Accounting Interview Questions

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.

What Did You Do In Your Last Project

There are no clear answers, only guidelines, for this one. It’s common for interviewers to ask about your career trajectory and previous projects, so make a quick list of points in advance so you can speak to the projects that you think best represent your work.

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.

How Do You Decide The Level Of Testing Needed For Each Application

Understanding how you decide on different requirements in the testing process helps the interviewer know what level of skill you have.

Example:I use the Cyclomatic Complexity principle to determine whether the application can be tested, understood by all involved and reliable enough for testing. By applying this principle, I can determine the level of complexity of the application, with more complex applications requiring more in-depth testing.

Define Defect Removal Efficiency

Ans: Defect Removal Efficiency is a testing metric that indicates the development teams efficiency in fixing errors and issues before releasing the software. It is measured as the ratio of fixed defects to the total number of discovered issues. For instance, if there were 80 discovered defects during the testing and 60 were fixed, the DRE will be 80/60 = 1.3%.

What Do You Mean By Defect Triage

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

Defect triage is a procedure in which defects are prioritised depending on a variety of characteristics such as severity, risk, and the amount of time it will take to fix the fault. The defect triage meeting brings together several stakeholders – the development team, testing team, project manager, BAs, and so on to determine the order in which defects should be fixed.

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 Regression Testing In Software Testing

The dictionary definition of regression is the act of going back to a previous place or state. In software, regression implies that a feature that used to work suddenly stopped working after a developer added a new code or functionality to the software.

Regression problems are pervasive in the software industry, as new features are getting added all the time. Developers don’t build these features in isolation, separate from the existing code. Instead, the new code interacts with the legacy code and modifies it in various ways, introducing side effects, whether intended or not.

As a result, there is always a chance that introducing new changes may negatively impact a working feature. It’s important to keep in mind that even a small change has the potential to cause regression.

Regression testing helps ensure that the new code or modifications to the existing code don’t break the present behaviour. It allows the tester to verify that the new code plays well with the legacy code.

Explain In A Testing Project What Testing Activities Would You Automate

Software Developer Aptitude Test Sample

In testing project testing activities, you would automate are

  • Tests that need to be run for every build of the application
  • Tests that use multiple data for the same set of actions
  • Identical tests that need to be executed using different browsers
  • Mission critical pages
  • A transaction with pages that do not change in a short time

56. What is Retesting?

To ensure that the defects which were found and posted in the earlier build were fixed or not in the current build. Say, Build 1.0 was released. Test team found some defects and posted. Build 1.1 was released, now testing the defects 1.0.1 and 1.0.2 in this build is retesting.

Complete Guide: Retesting

57. What is Regression Testing?

Repeated testing of an already tested program, after modification, to discover any defects introduced or uncovered as a result of the changes in the software being tested or in another related or unrelated software components.

Usually, we do regression testing in the following cases:

  • New functionalities are added to the application
  • Change Requirement
  • Environment change
  • Read a detailed guide on Regression Testing

    58. What do you mean by regression and confirmation testing?

    Regression Testing: Testing team re-execute the tests against the modified application to make sure whether the modified code breaks anything which was working earlier.

    Confirmation Testing: Usually testers report a bug when a test fails. Dev Team releases a new version of the software after the defect is fixed. Now the testing team will retest to make sure the reported bug is actually fixed or not.

    59. What is GUI Testing?

    Graphical User Interface Testing is to test the interface between the application and the end user.

    Mention A Few Advantages Of Automated Testing

    The following are some major advantages of automated testing

    • Automated test execution is quick and saves a significant amount of time.
    • Human mistakes are eliminated during testing when test scripts are carefully prepared.
    • CI tools like Jenkins, which may also be set to distribute daily test results to key stakeholders, can be used to schedule test execution for a nightly run.
    • Automation testing uses a lot less resources. Test execution requires nearly no time from QAs once the tests have been automated. QA bandwidth can be used for other exploratory work.

    What Are The Different Kinds Of Frameworks

    • Data-driven framework:

    The test data of this kind is generated from external files like excel, CSV, XML, etc. The data relating to the test cases rely outside on the input and verification values maintained using the variables.

    • Keyword-driven framework:

    The data tables and the keywords are developed independently of the automation test cases. In this framework, the functionality of the test scenarios is documented in the table step by step.

    • Module-based testing framework:

    Isolated and Logical modules are made out of the application that is under test. Independent test scripts are written for each module. These scripts are then clubbed together as a whole.

    • Behaviour driven testing framework:

    The test scripts are written in such a way that the automation is done on the functionality or features to ensure the readability, understanding, and reliability to either the business experts or developers, or other testers.

    • Hybrid testing framework:

    The combination of more than one of the above-mentioned frameworks by leveraging the benefits of each is called a Hybrid testing framework.
