Thus, a process that is set by QA is implemented by QC. QC is the responsibility of the testing team. The aim of performing testing is to find bugs and make sure that they get fixed. Thus, it helps to maintain the quality of the product to be delivered to the customer. Choosing automated testing over manual testing depends on the following factors:. Bug release: A bug release is when a particular version of the software is released with a set of known bug s.
Performance is identified with achieving response time, throughput, and resource-utilization levels that meet the performance objectives for a project or a product.
Monkey testing is a technique in software testing where the user tests the application by providing random inputs, checking the behavior of the application or trying to crash the application.
Exploratory testing is an approach to software testing, wherein testers learn simultaneously about the test design and test execution. In other words, it is a hands-on approach where testers are involved more in the test execution part than in planning. System testing is a black-box testing technique, used on a complete integrated system, where it will test the system compliance as per the requirement.
Test reports will help us find the current status of a project and its quality. This can help stakeholders and customers take necessary actions.
The complete documentation of test reports will help analyze different phases of the project. However, this will not cause any failure to the application because the conditions will never be met. Above interview questions will help you clear the Selenium certification exam. This is informative and explains different ways to validate a code and different types of testing are well derived.

You should prepare to be asked general questions, questions about your experience and background in software testing and in-depth questions that reveal your knowledge about testing processes.
Depending on the company, an interviewer might ask you questions based on sample fragments of code. Each company creates or maintains different types of software, so knowing some information about the company you are interviewing with can help you prepare for your interview. Toward the beginning of the interview, you are likely to hear a few more generalized questions.
These general questions are used by the interviewer to discover your interest in the job and your personality:. What hobbies do you have outside of software testing? How would you describe yourself as a software tester? Why did you choose manual testing over quality assurance? As the interview progresses and the person speaking with you starts to get a feel for your personality, questions directed toward your background will come into play. These background questions can help the interviewer understand more about your experience in the software industry and manual testing field:.
How much experience do you have with software testing? What kind of software have you tested previously? What kinds of software testing tools have you used before?
What's the difference between manual testing and quality assurance? Can you explain the various tasks of a manual tester? Have you taken the CSTE testing certification exam? What exams or tests have you taken for software testing?
Have you been trained in manual testing or software testing? What are the different types of software testing? Beyond what you have done or learned in the past, at some point your actual knowledge will likely be quizzed, to prove that you can really do the job. These in-depth questions can help an interviewer understand your comprehensive knowledge about manual testing:. What is the role of a moderator in software testing?
What are the differences between load, stress and performance tests? While writing white box test cases requires more architectural understanding and is not available at the start of the project.
Bottom-up testing is an approach to integration testing, where the lowest level components are tested first, then used to facilitate the testing of higher level components. The process is repeated until the component at the top of the hierarchy is tested. Breath testing is a test suite that exercises the full functionality of a product but does not test features in detail.
Code Walk Through is the informal analysis of the program source code to find defects and verify coding techniques. End-to-end testing is done after functional testing. The purpose behind doing end-to-end testing is that. A test harness is configuring a set of tools and test data to test an application in various conditions, and it involves monitoring the output with expected output for correctness.
Risk-based Testing is the term used for an approach to creating a Test Strategy that is based on prioritizing tests by risk. The basis of the approach is a detailed risk analysis and prioritizing of risks by risk level. Tests to address each risk are then specified, starting with the highest risk first. Preventative tests are designed early; reactive tests are designed after the software has been produced. Decision table testing is used for testing systems for which the specification takes the form of rules or cause-effect combinations.
In a decision table, the inputs are listed in a column, with the outputs in the same column but below the inputs. The remainder of the table explores combinations of inputs to define the outputs produced. The techniques of equivalence partitioning and boundary value analysis are often applied to specific situations or inputs. However, if different combinations of inputs result in different actions being taken, this can be more difficult to show using equivalence partitioning and boundary value analysis, which tend to be more focused on the user interface.
The other two specification-based techniques, decision tables, and state transition testing are more focused on business logic or business rules. A decision table is a good way to deal with combinations of things e. The difference between a pilot and beta testing is that pilot testing is actually done using the product by the group of users before the final deployment, and in beta testing, we do not input real data, but it is installed at the end customer to validate if the product can be used in production.
Testing technique: — Is a process for ensuring that some aspects of the application system or unit functions properly there may be few techniques but many tools. Testing Tools: — Is a vehicle for performing a test process. The tool is a resource to the tester, but itself is insufficient to conduct testing. Learn More About Testing Tools here. Component testing, also known as unit, module, and program testing, searches for defects in and verifies the functioning of software e.
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. Here is an awesome video on Unit Testing. Testing the end to end functionality of the system as a whole is defined as a functional system testing.
Random testing is often known as monkey testing. In such type of testing data is generated randomly often using a tool or automated mechanism. With this randomly generated input, the system is tested, and results are analyzed accordingly. These testing are less reliable; hence it is normally used by the beginners and to see whether the system will hold up under adverse effects. In contrast to informal reviews, formal reviews follow a formal process.
A typical formal review process consists of six main steps:. The moderator or review leader leads the review process. He or she determines, in co-operation with the author, the type of review, approach and the composition of the review team.
The moderator performs the entry check and the follow-up on the rework, in order to control the quality of the input and output of the review process.

I'm sure that with a thorough knowledge of these Questions and Answers, you can appear for any QA Testing Interview confidently and get through very successfully. The questions will emphasize more on the quality processes and the strategy, so please see that the question will not be asked for Testing.
Quality Assurance is the process of planning and defining the way of monitoring and implementing the quality test processes within a team and organization. This method basically defines and sets the quality standards of the projects.
Quality Control is the process of finding defects and providing suggestions to improve the quality of the software. The methods used by Quality Control are usually established by the quality assurance.
It validates whether the software built by the development team meets the requirements set by the user and the standards set by the organization. QA activity should start from the beginning of the project. The more early it starts the more benefit it is to set the standards for achieving the quality.
Test Strategy is at a higher level, mostly created by the Project Manager which demonstrates the overall approach of the testing for the entire project, whereas Test plan basically depicts the how the testing should be performed for a particular application, falling under a project. Software Testing Life Cycle refers to a testing process which has specific steps to be executed in a definite sequence to ensure that the quality goals have been met. In simple words, a good test case is one which finds a defect.
But all test case will not find defects, so A good test case can also be one which has all the prescribed details and coverage. Q 7 What would you do if you have a large suite to execute in very less time?
