Manual Testing Interview Questions – Every QA Should Read
In today’s competitive world, testing is critical to the success of any software product. Manual tests are important in software development because they can be used in situations where automated testing isn’t possible. This Blog about Manual Testing Interview Questions will help you learn software testing.
With this thorough list of over 120 manual testing interview questions and answers, you’ll be ready for your software testing interviews. These manual testing interview questions are appropriate for both fresher and experienced candidates.
Let’s start by going through some of the most common Manual Testing Interview Questions.
120+ Manual Testing Interview Questions:
Below are the 120+ manual testing interview questions and answers:
1) What is Software Testing?
Software testing is a process to test whether the actual product is matched with an expected requirement or not and if getting an issue then it could be resolved before the released product to the market and at last ensure that product is bug-free.
2) What is manual testing?
Manual testing is a type of testing that involves the validation of the requirements of the application by executing a predefined set of test cases manually without the use of any automation tool.
3) Why is Software Testing Required?
Software testing is a process that verifies the product is secure and good enough to be released to the market. The reason for software testing is to find defects, errors, and unmatched or missing requirements compared to the actual requirement.
- It points out the bug and error which is made during the development.
- If identify issues at the starting stage of development, then we can reduce the coding cycles.
- Ensure that product is defect-free, and the product meets the market standard.
- Make sure that the application doesn’t result in any failures.
4) What are the two main categories of software testing?
Software testing is a vast domain, but it can be categorized into two types, such as:
- Manual Testing– Manual testing is the oldest type of software testing where the tester executes all test cases without using any tools, mean-tested whole application manually by QA testers.
- Automation Testing– Automation Testing is the process of executing repeating predefined test cases using an automation testing tool. The main focus of automation testing is replacing manual activity with automated test cases
5) Do you know the difference between quality control and quality assurance?
|Quality Control||Quality Assurance|
|Quality Control is a product-based approach of running a program to define if the application has any defect, as well as make sure software fulfils all the requirements.||Quality assurance is a process-oriented approach that focuses on making sure that the methods, techniques used to make quality deliverables are applied correctly.|
|QA means planning for doing any testing process.||QC means doing action for executing the planned process.|
|QA does not involve executing the test cases.||QC is always involved in executing the test cases.|
|QA is the technique of handling the quality of the application.||QC is a method to verify the quality of software|
6) What is quality control? Is it similar to Quality Assurance?
Quality control is a product-based strategy of running a program to define if it has any defect, as well as create sure software fulfils all requirements with end-user.
So, Quality control is not similar to Quality assurance, Quality assurance is a process-oriented approach. It is focused only on process, methods, and techniques which is used to create quality deliverables that are applied correctly.
7) What different types of manual testing are there?
Manual testing is divided into different types, which are listed below:
- Acceptance Testing
- System Testing
- Black Box Testing
- White Box Testing
- Unit Testing
- Integration Testing
8) Explain the difference between alpha testing and beta testing.
Alpha and beta both testing types are types of user acceptance testing. Find the brief description of alpha vs beta testing here.
- Alpha Testing – Alpha testing is a process that is performed before realizing the product to identify a bug.
- Beta Testing – Beta testing is a process that is performed by the end-user after realizing the product.
9) What are the different levels of manual testing?
We have different 4 levels of manual testing, which is described below:
- Unit testing – Unit testing is testing where we test separate units or the smallest pieces of source code. The goal of unit testing is to separate all parts and show that all parts are worked without any defect.
- Integration Testing – It is a type of testing where individual units are combined and tested there is no bug after integrating the separate units.
- System Testing – System testing is defined as the testing of the whole integrated product. System testing is black-box testing, and it is performed in the form of a functional requirement specification.
- User Acceptance Testing – User acceptance testing is a final level of testing, UAT is performed by the end-user or client. In UAT testing verify that software or product is ready to be released or not into the real world.
10) What is a test in manual testing?
The tested environment is used for application testing; we can test hardware as well as software programs also. The test consists of hardware, network configuration, software, and other related software.
11) Explain the procedure for manual testing.
In The manual testing process, follow the below steps:
- Project Planning and Control
- Project Design
- Test case Execution
- Evaluating exit criteria and Reporting
- Test Closure activities
12) What is the test case?
One type of document that has a set of conditions that is performed on the particular application in order to verify the expected result of the feature is called a test case.
Test case documents include test steps, preconditions, postconditions, test data, and verification requirements.
13) What is API testing?
Perform software testing API directly from their functionality, reliability, security, and performance in API testing.
The application has three separate layers:
- First is the Presentation Layer or user interface.
- The second layer is Business Layer or application user interface for business logic processing.
- The third and last layer is Database Layer for
14) Do you know the difference between verification and validation in testing?
Verification testing is done without executing the code. Verification is a static technique. Verification is coming before validation. Verification is the process where to verify the quality of the product. Verification is to reduce the chances of failure in the product.
Validation testing is including the execution of the code. Validation is dynamic testing. Validation comes after Verification. Validation is the process in which the actual requirements of the customer match with the software functionality. Validation is done after completing the development process.
15) Do you know the difference between a bug and a defect?
The tester finds fault in the software during testing it is called a bug and when a product goes to live that time developer detects the difference between the actual result and the expected result is called a defect.
Alpha Vs Beta Testing: What’s the Difference?
Before we start alpha vs beta testing, We should know what is alpha testing and what is beta testing.
What is Alpha Testing?
Alpha testing is conducted to determine defects before releasing the final product to end users or to the public. Then the main goal of alpha is to identify the tasks that a typical user might perform and test them.
What is Beta Testing?
Beta testing is a type of software testing which is performed by real users of the software in a real environment. Beta testing is also one type of user acceptance testing. This testing helps the tester to test products in the customer’s environment.
Difference: Alpha Vs Beta Testing
The difference between alpha vs beta testing is as below:
|Alpha Testing||Beta Testing|
|Alpha testing needs a testing atmosphere or a lab for testing.||Beta testing doesn’t need a testing atmosphere or lab for testing.|
|Alpha testing may need a lengthy execution cycle.||Beta testing needs only a few weeks of execution.|
|In alpha testing, developers can directly address critical bugs or fixes.||Most of the bugs or feedback collected from the beta testing will be executed in future versions of the product.|
|Alpha Testing||Beta Testing|
|The goal of alpha testing is to estimate the quality of the product.||The goal of beta testing is to estimate customer satisfaction.|
|To confirm Beta eagerness||To confirm release eagerness|
|Concentrate on finding defects or errors||Concentrate on gathering recommendations/feedback and consider them effectively|
|Confirm that, does the product works properly without any bugs.||Confirm that, do clients like the released product.|
|Alpha Testing||Beta Testing|
|Multiple test cycles performed||Only performed 1 or 2 test cycles|
|Separately each test cycle stays for 1 – 2 weeks||Separately each test cycle stays for 4 – 6 weeks|
|The duration of the cycle also depends on how many bugs are found and how many new features are added during alpha testing.||The duration of the cycle may expand based on the end user’s feedback/recommendation.|
|Alpha Testing||Beta Testing|
|An acceptable number of bugs were missed in earlier testing activities.||Major finished product with very a much smaller number of defects and crashes.|
|Incomplete components and documentation.||Almost finished components and documentation.|
What is GUI Testing?
GUI Testing is a type of testing in which an applications’ Graphical User Interface (GUI) is tested to make sure it is in line with the expectations. GUI testing involves checking the objects on the UI (User Interface), which are the objects that we can see on the screen. Anything the user sees in the system or application is a GUI. Let us consider that if you visit a website, then the homepage is the GUI (graphical user interface) of the site. The source code will not be visible as the user can see only the UI interface. Mainly the focus of GUI testing is on the design pattern, images, alignment, spellings and the overall look and feel of the UI.
Why do we need GUI testing?
To get the answer you need to think as a user, not as a tester. It is the User Interface of the Software/Application that is a deciding factor to know whether a user is going to use the Application further or not. The looks and designs of the Application/Software are what a typical user will first look at. Secondly, he checks how easy it will be for him to understand and navigate through the UI. If the Software/Application is more complex and not appealing or if the user is not comfortable with the Interface design, then he is not going to use that Application again. That’s the reason, GUI testing is a matter for concern and should be taken very seriously. Also, proper testing should be carried out in order to make sure that GUI is free from any issues.
How to create test cases and how to do GUI testing?
UI Testing mostly involves the checking the various elements on the screen for their look and feel, the test cases should be written in such a way that they validate the following points for each of the UI objects. Size, position, width, and height of the objects with reference to other objects on the screen, Error messages displayed on the screen, the color and font of the error message. Errors are normally in Red color. Readable and inconsistent across the application unless specified by the client. Checking the same screen in different resolution with the help of zooming in and zooming out like 640 x 480, 600×800, etc. Also if there is a requirement you may want to check it in a mobile browser as well. Font color, hyperlink color, error/warning message color, etc. Quality of the images on the screen, if applicable. Spellings, grammar, and punctuations. Scrollbars according to the size of the page if any. Checking disabled fields if any. Checking the size of the images.
Challenges in GUI Testing:
The list of GUI test cases can be very exhaustive and time-consuming and it requires a lot of manual effort and the quality of the testing would depend on the skills of the tester. Number of automation tools available is very limited GUI is usually unstable during the initial development phases, so GUI testing is postponed to the end of the testing cycle, which sometimes creates a time crunch.
