Manual Testing: What is it?
Manual testing is done by human testers, creating and carrying out each test case manually, without the use of automated tools or scripts. This course is referred to as manual testing. By this method, testers examine the software application’s functionality, usability, performance, and other quality factors while assuming the role of end users and manually testing it to find bugs.Â
By reporting the defects to the developers, they subsequently draw attention to these problems. Tracking tools can occasionally be used for bug reporting. QA engineers manually examine a freshly constructed webpage to ensure the user interface, menu tabs, clickable links, and other features function as intended. This is an example of manual testing. Here, they ensure that the site’s appearance and feel meet visitors’ expectations.
Why Is Manual Testing Required?
Manual testing is required as a preliminary stage to comprehend and confirm if the application is appropriate for users. With manual testing, one can appraise the programme from the viewpoint of the user, as well as its general user experience, intuitiveness, and convenience of use. Implementing exploratory or ad hoc testing is another reason why manual testing is required. To authenticate that all features and UI elements are operational as proposed, testers can randomly navigate through the product.
Ad hoc testing is a testing practice where testers perform tests without a pre-established test plan or set of test cases. Under the exploratory testing practice, testers do tests using their instinct, experience, and expertise. When it comes to exploratory testing or situations requiring non-deterministic behaviour, QA engineers may resort to manual testing because certain parts of software behaviour are challenging to automate. It enables testers to investigate such areas and spot any problems by putting their creativity, intuition, and domain expertise to use.Â
There are several objectives associated with manual testing that help developers and testers create high-quality products. It supports the identification of defects, evaluation of usability, verification of specification requirements, and user-perspective testing of user scenarios. Before a software application is released, manual testing generally helps to increase its quality, dependability, and customer happiness. Additionally, it enhances automated testing efforts and is essential to guaranteeing a comprehensive human review of the product.

Let’s now analyse some frequently requested Manual Testing Interview Questions and answers:
Software testing: What Is It?
The process of determining the accuracy, comprehensiveness, and quality of generated software is called software testing. It involves several tasks carried out to identify software bugs so they can be fixed before the product is made available on the market.
Which two primary software testing categories exist?
Although there are many different aspects of software testing, two general categories can be used to describe it:
Test cases are manually carried out by testers without the use of test automation tools in manual testing, which is the most traditional kind of software testing. It indicates that QA testers are testing the software programme manually.
Automation testing is a procedure that involves repeating pre-defined operations in test cases with the aid of tools, scripts, and software. The goal of test automation is to substitute efficient technologies or gadgets for labour-intensive human labour.
What distinguishes quality assurance from quality control?
In a product-oriented approach, quality control involves executing a programme to check for errors and to ensure that the software satisfies all stakeholder needs.
Ensuring the proper application of methods, techniques, and processes used to produce excellent deliverables is the main goal of quality assurance, a process-oriented approach.
Quality control: what is it? Does this resemble quality assurance?
Quality control is a product-focused methodology that involves executing a programme to identify any flaws and verify that the software satisfies all stakeholder criteria.

The steps involved in manual testing are:
- Development and Control
- Analysis and Design
- Application and Performance
- Evaluating Exit Standards and Reporting
- Test Conclusion Activities
What do you understand by positive and negative testing?
Positive testing
In positive testing, a software application is validated using legitimate data sets as input in this kind of testing procedure. All it serves to do is verify that the programme performs as intended. Â
Negative testing
Here, software applications are checked against invalid input data sets for validation. It is merely used to determine whether the system displays an error when it should not. Negative testing is regarded as an extremely important component in the execution of test cases.
What does the word “quality” in testing mean?
Relatively free of errors, timely and cost-effective delivery, fulfilment of specifications and/or expectations, and maintainability characterise high-quality software. It will rely on the nature of the “customer” and how influential they are overall.

Can you tell me about SDLC?
SDLC stands for Software Development Life Cycle. It includes all phases of the software development life cycle, such as requirement analysis and collection, designing, coding, testing, deployment, and maintenance.
What Are Commonly Applied Documentations Associated With Software Testing?
- Test Plan
- Test Scenario
- Test Case
- Traceability Matrix
Please explain the test case
A test case is a statistic that indicates the portion of the source code that has been evaluated, allowing the tester to evaluate the efficacy of their work. Testers can use it to determine if they are testing everything that should be tested. Depending on how they approach testing, various people may see test coverage differently.
How many levels are there in manual testing? Please name them
There are four levels of manual testing.
- Unit testing
- Integration testing
- System testing
- User acceptance testing
What is Code coverage?
The number of code blocks, lines, or arcs executed during a test suite run is known as code coverage, which is a metric used in software testing.
What are the methods to determine code coverage?
There are four methods.
- Statement Coverage
- Decision Coverage
- Branch Coverage
- Toggle Coverage
Please mention techniques for black box and white box testing.
Black Box
- Equivalence Partitioning
- Boundary value analysis
- Cause-effect graphing
White box
- Statement Coverage
- Decision Coverage
What is alpha testing and beta testing?
At the developer’s location, alpha testing occurs before release. Beta testing is done by potential clients on their websites.
In testing, what distinguishes validation from verification?
Verification is a method of static analysis. In this case, testing takes place without running the code. Walkthroughs, inspections, and reviews are a few examples.
Validation is a dynamic analysis technique where code is executed to test the system. Techniques for both functional and non-functional testing are examples.
What is covered in test plans?
The Test Plan Document contains a variety of details, including Test Design, Scope, Test Strategies, and Approach.
- Identifier for test cases
- Scope
- Characteristics to be examined
- Features that won’t be tested
- Test approach and strategy
- Deliverables for testing
- Obligations
- Personnel and education
- Complications and Backup Plans
What is Regression Testing and when should it be performed?
To make sure the functionalities that are now in place are functioning properly, regression testing involves selecting some or all of the previously run test cases and running them again. It is advisable to do regression testing after the software modifications or environmental shifts.
Can inspections and reviews be regarded as a part of testing?
To increase quality and identify errors, both are helpful.
How does one distinguish between a defect, a bug and an error?
Any legitimate software error found during testing is referred to as a bug. Once the product goes live, the developer finds defects, which are discrepancies between expected and actual results.
Whereas, A software developer’s mistake, misinterpretation, or misconception is called an error. Programmers, testers, analysts, and software engineers are all considered developers.
Explain the test harness
A test harness consists of software and test data organised such that a programme unit can be tested under various scenarios, such as load, stress, and data-driven scenarios, while its behaviour and outputs are tracked. Two primary components make up Test Harness:
A repository for test scripts – An engine for executing tests
Can we understand what a test closure is?
A test closure is a report that provides an overview of all the tests carried out throughout the software development life cycle, together with a thorough analysis of the mistakes and faults that were fixed. This memo includes the overall number of experiments, the number of experiments that were completed, the number of flaws that were found, the number of imperfections that were resolved, the number of bugs that were not resolved, the number of bugs that were rejected, and so on.
Describe the defect life cycle
Defects move through different stages throughout their lifetimes, which is known as a defect life cycle. A flaw is closed once it has been identified and is confirmed not to be reproduced, marking the end of the cycle.
List various stages in a defect life cycle
- New
- Assigned
- Active
- Ready to test
- Verified
- Closed
- Reopen
- Duplicate
- Out of work
- Moved to next iteration / Deferred
What do you mean by Critical Bug?
When a software defect seriously impairs its functionality, usability, security, or performance, it’s called a critical bug. Bugs that are considered critical may result in software crashes, unexpected or erroneous outcomes, or jeopardise system security.
Pesticide paradox- What do you understand? How are you going to get over that?
Repeating the same tests repeatedly will eventually cause the test cases to stop finding new bugs. Developers may choose not to investigate other regions and instead take extra care in the areas where testers reported more faults.
What are Experience-based testing techniques? Name them
Discovery, research, and learning are the main goals of experience-based testing. Continuous product analysis and study are done by the tester, who then uses his abilities, characteristics, and expertise to create test plans and test cases to carry out the required testing.
- Exploratory Testing
- Error Guessing
Explain Defect Cascading in Software Testing
The process of causing more application errors is known as defect cascading. Unnoticed errors during testing lead to the induction of more defects. Multiple defects appear in the latter stages of development. Defect cascading makes it difficult to pinpoint the afflicted feature if it keeps affecting other programme features. To tackle this problem, you could create several test cases, but it would still be challenging and time-consuming.
Describe smoke testing and sanity testing
Smoke testing is done to ensure that the system’s vital components are operating as intended. Sanity testing is done to verify that the defect or new functionality has been fixed.
Can you explain static testing and dynamic testing?
Before deploying the code, static testing is done during the verification phase.
Dynamic testing is carried out after the deployment of the code, commencing during the validation phase.
Define Alpha and Beta testing
Software is tested using an approach known as “alpha testing” to find issues before the product is made available to the general public or actual users. User acceptance testing includes alpha testing.
Beta testing is carried out in a genuine setting by actual software application users. User acceptance testing also includes beta testing.
What is an API?
The code is typically not written from scratch by developers when they are creating software. Rather, they make use of other libraries that are the product of outside parties. Through the provision of an understandable interface, an API enables communication between two independent software components.

When should you stop testing, and how will you decide?
In real-time projects, determining when to end testing involves a lot of considerations.
- The point at which requirement coverage is met
- Terminations for testing or releases
- When every penny allotted for testing is used
- After the test cases reach the predetermined pass percentage
- There is less than acceptable risk in the project.
- Every major bug and roadblock has been fixed.
- After the requirements for acceptance are satisfied
- When the time for testing in Alpha and Beta is over
- Based on a management decision Once the requirements for acceptance are satisfied
- Once the time for Alpha and Beta testing has passed
- Relies on the management’s choice
If the specifications haven’t frozen yet, how do you test a product?
It’s possible that a product does not have a requirement stack available. If a programme contains significant unanticipated functionality, it could require a significant amount of work and would point to underlying issues with the software development process. The feature should be eliminated if it isn’t essential to the application’s goal. If not, develop a test strategy based on the product’s assumed characteristics. However, be sure that the test strategy thoroughly documents every assumption.
When should one prefer manual testing to automated testing?
The following circumstances warrant the consideration of automated testing over manual testing:
- When testing must be performed regularly
- Test involves stages that are repeated
- When the testing process is running behind schedule, the tests must be conducted in a regular runtime environment
- When there is a large amount of code that requires frequent testing
- Every execution must have a report
What are the qualities of a Successful Test Engineer?
A competent test engineer must have the following qualities:
- meticulous and well-organized.
- possesses superior problem-solving abilities.
- possesses excellent teamwork and communication abilities.
- Keeping up with the latest technologies is essential for a competent test engineer.
Can we do system testing at any stage?
System testing involves testing the entire software package to make sure that all of the requirements are met by the final product. Therefore, no. Only once every unit is installed and operational can the system testing begin. Before User Acceptance Testing system testing is typically conducted.
What are the best ways to write manual testing test cases?
The following are some recommended approaches for creating test cases:
- Sort test cases by priority: Sort test cases according to the application’s risk profile and the project schedule.
- Remember the 80/20 rule: Ideally, 80% of the application should be covered by 20% of the test cases to guarantee adequate coverage.
- Sort the test cases: Put all of the test cases in one list and group them based on functionality and business scenarios.
- Create modular test scenarios: As much detail and modularity as possible should be included in the test cases.
- Eliminate redundant test cases. Eliminate duplicate and irrelevant test cases.
Why did you decide to pursue a profession in software testing?
Software testing is similar to solving a puzzle in that it involves not only discovering flaws but also breaking into the system through stress testing, which is why I would love to be a software tester.
