The basic testing to consider include Blackbox testing, Integration testing, Whitebox testing, User acceptance testing, Load testing , Acceptance testing, Performance testing, and Smoke testing. V model: Related titles. Can you please explain with example? Be developing the test plans, we can also define the expected results for testing of the products for that level as well as defining the entry and exit criteria for each level. There can be multiple builds in the testing cycle of an application.
Are you planning to attend a software testing interview soonest? There are several questions you are likely to be asked during the interview. The earlier you know what to anticipate the better the outcome of the interview would be.
So, here are the top 30 software testing interview questions you may be asked, as well as their answers. Software testing is the act of operating a system or application under control and then assessing their results. It is intentionally simulating a problem situation in order to work out a possible remedy in case a situation like that actually happens.
The basic testing to consider include Blackbox testing, Integration testing, Whitebox testing, User acceptance testing, Load testing , Acceptance testing, Performance testing, and Smoke testing.
Software Quality Assurance also known as Software QA, encompasses the entire process of developing software: This solely depends on the context or size of the project, the methodology of development, risks involved, and the experience and skills of the developers.
Generally, every project would need testers, except in some cases. A project that is non-trivial sized or with non-trivial risks would need a testing staff.
But whereby the project is for a short term, low risk, small, and with programmers that are highly experienced that are making use of test-first development or unit testing, such project may not need a test engineer for it to do well. Verifications are reviews and meetings which are intended to help evaluate documents, code, specifications, and requirements. It is usually done with checklists, walkthroughs, issues lists, and inspection meetings. Validation, on the other hand, entails the real testing and it is done after completing the verification.
This is the act of retesting a program that has been tested previously in order to be sure that there has not been any fault following the modification or that no new fault has been introduced. A software project test plan is a document that explains the objective, approach, focus, and scope of a software testing. You need to report the bug and then assign it to developers that can take care of it.
When you have fixed the problem, retest the fixes, decide the requirements for regression testing in order to be sure that no more problems are eventually caused by the fixes. If it is a small project or group, it may be better to use a more ad-hoc process, depending on the customer and project type.
In simple words, what the system actually does is functional testing.
To verify that each function of the software application behaves as specified in the requirement document. Testing all the functionalities by providing appropriate input to verify whether the actual output is matching the expected output or not. It falls within the scope of black box testing and the testers need not concern about the source code of the application. In simple words, how well the system performs is non-functionality testing.
Non-functional testing refers to various aspects of the software such as performance, load, stress, scalability, security, compatibility etc. It is also known as pre-production testing. This is done by the end users along with the testers to validate the functionality of the application. After successful acceptance testing. Formal testing conducted to determine whether an application is developed as per the requirement. It allows the customer to accept or reject the application.
Alpha testing is done by the in-house developers who developed the software and testers. Sometimes alpha testing is done by the client or outsourcing team with the presence of developers or testers. Beta testing is done by a limited number of end users before delivery.
Usually, it is done in the client place. Gamma testing is done when the software is ready for release with specified requirements. It is done at the client place. It is done directly by skipping all the in-house testing activities. Smoke Testing is done to make sure if the build we received from the development team is testable or not. Sanity Testing is done during the release phase to check for the main functionalities of the application without going deeper. It is also called as a subset of Regression testing.
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. Test team found some defects Defect Id 1.
Build 1. 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. Graphical User Interface Testing is to test the interface between the application and the end user.
Recovery testing is performed in order to determine how quickly the system can recover after the system crash or hardware failure. It comes under the type of non-functional testing. What is Globalization Testing?
Globalization is a process of designing a software application so that it can be adapted to various languages and regions without any changes. Localization is a process of adapting globalization software for a specific region or language by adding local specific components. What is Installation Testing? It is to check whether the application is successfully installed and it is working as expected after installation.
What is Formal Testing? It is a process where the testers test the application by having pre-planned procedures and proper documentation. Identify the modules or functionalities which are most likely cause failures and then testing those functionalities.
What is Compatibility Testing? It is to deploy and check whether the application is working as expected in a different combination of environmental components. What is Exploratory Testing? Usually, this process will be carried out by domain experts. They perform testing just by exploring the functionalities of the application without having the knowledge of the requirements.
Perform abnormal action on the application deliberately in order to verify the stability of the application. To verify whether the application is user-friendly or not and was comfortably used by an end user or not.
The main focus in this testing is to check whether the end user can understand and operate the application easily or not. An application should be self-exploratory and must not require training to operate it. Security testing is a process to determine whether the system protects data and maintains functionality as intended. Running a system at high load for a prolonged period of time to identify the performance problems is called Soak Testing.
Endurance testing is a non-functional testing type. It is also known as Soak Testing. Refer Soak testing. Performance is concerned with achieving response times, throughput, and resource-utilization levels that meet the performance objectives for the project or product. It is to verify the behavior of the system once the load increases more than its design expectations. Scalability testing is a type of non-functional testing.
It is to determine how the application under test scales with increasing workload. Concurrency testing means accessing the application at the same time by multiple users to ensure the stability of the system. This is mainly used to identify deadlock issues. Fuzz testing is used to identify coding errors and security loopholes in an application. By inputting massive amount of random data to the system in an attempt to make it crash to identify if anything breaks in the application.
Ad-hoc testing is quite opposite to the formal testing. It is an informal testing type. In Adhoc testing, testers randomly test the application without following any documents and test design techniques. This testing is primarily performed if the knowledge of testers in the application under test is very high.
Testers randomly test the application without any test cases or any business requirement document. Interface testing is performed to evaluate whether two intended modules pass data and communicate correctly to one another. What is Reliability Testing? Perform testing on the application continuously for long period of time in order to verify the stability of the application. Bucket testing is a method to compare two versions of an application against each other to determine which one performs better.
Testing all the functionalities using all valid and invalid inputs and preconditions is known as Exhaustive testing. Defects detected in early phases of SDLC are less expensive to fix. So conducting early testing reduces the cost of fixing defects.
Defect clustering in software testing means that a small module or functionality contains most of the bugs or it has the most operational failures.
Pesticide Paradox in software testing is the process of repeating the same test cases, again and again, eventually, the same test cases will no longer find new bugs. So to overcome this Pesticide Paradox, it is necessary to review the test cases regularly and add or update them to find more defects. Defect cascading in Software testing means triggering of other defects in an application.
When a defect is not identified or goes unnoticed while testing, it invokes other defects. It leads to multiple defects in the later stages and results in an increase in a number of defects in the application. The author leads the meeting and clarifies the queries raised by the peers in the meeting. Inspection is a formal meeting lead by a trained moderator, certainly not by the author. The document under inspection is prepared and checked thoroughly by the reviewers before the meeting.
In the inspection meeting, the defects found are logged and shared with the author for appropriate actions. Post inspection, a formal follow-up process is used to ensure a timely and corrective action. The variation between the actual results and expected results is known as a defect. If a developer unable to successfully compile or run a program then they call it as an error.
Once the product is deployed and customers find any issues then they call the product as a failure product. After release, if an end user finds an issue then that particular issue is called as a failure. It can be Critical, Major or Minor. In simple words, how much effect will be there on the system because of a particular defect. Defect priority can be defined as how soon the defect should be fixed.
It gives the order in which a defect should be resolved. Developers decide which defect they should take up next based on the priority. It can be High, Medium or Low. Most of the times the priority status is set based on the customer requirement. Submit button is not working on a login page and customers are unable to login to the application. Crash in some functionality which is going to deliver after couple of releases. Spelling mistake of a company name on the homepage.
A critical bug is a show stopper which means a large piece of functionality or major system component is completely broken and there is no workaround to move further. For example, Due to a bug in one module, we cannot test the other modules because that blocker bug has blocked other modules.
Bugs which affects the customers business are considered as critical. An error message pops up when a customer clicks on transfer money button in a Banking website. What is the difference between a Standalone application, Client-Server application and Web application? Standalone applications follow one-tier architecture. Presentation, Business, and Database layer are in one system for a single user. Client-server applications follow two-tier architecture.
Presentation and Business layer are in a client system and Database layer on another server. It works majorly in Intranet. Web server applications follow three-tier or n-tier architecture. The presentation layer is in a client system, a Business layer is in an application server and Database layer is in a Database server.
It works both in Intranet and Internet. In Software Development process, the bug has a life cycle. The bug should go through the life cycle to be closed. A bug which is actually missed by the testing team while testing and the build was released to the Production.
If now that bug which was missed by the testing team was found by the end user or customer then we call it as Bug Leakage. Releasing the software to the Production with the known bugs then we call it as Bug Release. These known bugs should be included in the release note. Defect age can be defined as the time interval between date of defect detection and date of defect closure.
Assume, a tester found a bug and reported it on 1 Jan and it was successfully fixed on 5 Jan So the defect age is 5 days. Error seeding is a process of adding known errors intendedly in a program to identify the rate of error detection.
It helps in the process of estimating the tester skills of finding bugs and also to know the ability of the application how well the application is working when it has errors. Assume that login button is not working. Even though you have a valid username and valid password, you could not move further because the login button is not functioning.
Boundary value analysis BVA is based on testing the boundary values of valid and invalid partitions.
