Where do you see yourself in five years as a developing test engineer? Can you describe a time when you encountered a software test challenge? What are the most important things you are looking for in your next software testing engineer role? Describe what makes an excellent software tester. Tell me about your experience in test engineering.
When you're pursuing a career in the engineering field, expect questions that define your background and experience to become a test engineer:. What software testing tools did you use in your previous job? How do you differentiate a symptom from a primary cause in testing?
Please explain a test strategy you have identified to be most effective. What is your work experience with object-focused programming languages? What software engineering test cases can you write for any remote desktop feature? How can you ensure the firm's staff is well-trained on testing protocols and procedures?
What strategy do you think is critical in developing testing methods for a product? What troubleshooting systems do you use to finalize your testing procedures? What experience do you have with emerging corner cases?
What made you want to do software test engineering? What software testing methods are you familiar with? Hiring managers ask questions about industry techniques and technologies that require more specific and in-depth responses than general interview questions.
Examples might include:. How well do you meet deadlines and operate under pressure? Describe best practices for crafting a test case. Can you name some useful configuration management tools? What if software is buggy? Can it be tested successfully? What is the validation process in software testing? Test drivers : Test drivers are used in a bottom-up testing approach and allow testing of the lower levels of the code when the upper levels of the code are not developed yet.
Endurance testing, also known as Soak testing, is a type of performance testing usually performed to check the performance of the system that is under constant use.
Its main purpose is to determine whether a system can sustain a continuous high load or not. Memory utilization is also monitored to identify potential leaks during this testing. Some of the endurance testing tools include:. Localization testing is a type of testing that is performed to ensure whether the software product offers full functionality and usability in a particular locale or not. It is simply used to verify the accuracy and suitability of the content.
It is not only about linguistics, but also about traditions, common herd behavior, and other similar factors. It generally deals with the functionality and GUI of the application. Path testing is a type of testing specially used to design test cases. In this type of testing, the control flow graph of a program is specially designed to identify a set of linearly independent paths of execution. Its main objective is to ensure that each path is covered and executed well. It also reduces or minimizes the occurrence of redundant tests.
Baseline Testing : It is a type of non-functional testing in which a set of tests are run to capture performance information. Using this gathered information, we can make required changes in the application and ultimately improve the performance and capabilities of the application. In general, it refers to a benchmark that usually forms the base of any new creation. During this testing, many errors are discovered and resolved. Benchmark Testing : It is a type of testing that involves both the developers and DBAs Database Administrators to determine current performance information.
Using this information, one can improve the performance of the same by matching it with the benchmarks industry standards. Its main objective is to compare the present and future software releases with their specific benchmark. Fuzz testing is a software testing technique in which a large amount of random data, called fuzz, is provided as input to the application simply to detect or discover security loopholes and coding errors in the software application.
It is more useful for bigger projects but it only detects a serious fault or defect. It is simply used to check the vulnerability of software and gives more effective results when used with beta testing, black box testing, etc. Data flow testing is a type of structural testing that is used to analyze the flow of data in the program. In this, a programmer can perform various tests on data values and variables.
It helps us in the following ways:. Agile testing is basically a software testing process that uses agile methodologies i. It evaluates the software from the customer's point of view. It does not require any development team to complete coding for starting QA, instead of testing and coding can go hand in hand. Features are tested as they are developed.
Some of its advantages include:. Selenium is a web browser automation tool that automates the test suits you need to run on a web browser. In software, many errors occur near the edges of the range of the data values. Typically, developers miss these boundary cases because they follow a happy path when developing and testing.
Boundary value analysis helps to discover the errors caused by extreme values. The tester chooses the test data at and immediately above and below the boundaries of the input domain of the data. For example, if an input field expects a string of 20 characters long, the tester tests it with strings of lengths 19, 20, and 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 behavior. It allows the tester to verify that the new code plays well with the legacy code. Unit testing is the process of testing a single unit of code in an isolated manner. The unit of code can be a method, a class, or a module.
Unit testing aims to focus on the smallest building blocks of code to get confidence to combine them later to produce fully functioning software. A unit test invokes the code and verifies the result with the expected result.
If the expected and actual outcomes match, then the unit test passes. Otherwise, it fails. It is a means of communication between two software components. An API abstracts the internal workings and complexity of a software program and allows the user of that API to solely focus on the inputs and outputs required to use it.
When building software, developers rarely write software from scratch and make use of other third-party libraries. An API allows two software components to talk to each other by providing an interface that they can understand. Another use of an API is to provide data required by an application. Let's say you are building a weather application that displays the temperature.
Instead of building the technology to collect the temperature yourself, you'd access the API provided by the meteorological institute.
Test coverage is a metric that indicates how much of the source code is covered by the tests, allowing the tester to verify the quality of their testing. It helps the tester figure out whether they are testing everything they're supposed to test.
Test coverage can mean different things to different people, depending on the particulars of their testing approaches. The only difference is that the browser automation can test this very quickly and often, whereas the same test would take a human tester a long time. Some essential tools for browser testing include Selenium, protractor. It is a low-risk way of testing variations of a new or existing functionality. You can choose a part of your users to use feature A. The other group uses feature B.
Then user feedback and response are evaluated using statistical testing to decide the final version of the feature. This allows the team to quickly gather feedback and test their initial hypothesis. Regression Testing : Regression testing, also known as generic testing, revolves around re-running functional and non-functional tests.
It is especially done to ensure whether previously developed and tested software still performs the same after a change or not. It can be performed either manually or using automated tests. Re-testing: Re-testing, also known as planned testing, is used for specific bugs after it has been fixed by the developers. Re-testing is performed to check the scenario under the same environmental conditions after detection has been fixed.
Regression vs Retesting:. It must investigate both functional requirements and non-functional requirements. Generally, it is performed by both testers and developers. Unit Testing: In unit testing, each component of the software is individually tested. Generally, unit testing is performed by developers.
Those systems that have a lot of interdependencies between their modules cannot be tested by unit testing. System vs Unit Testing:. Test Harness : Test harness, also known as the automated test framework, is a collection of software and test data required to unit test software modules during development. It is mostly used by the developers and helps in the automation and execution of unit test cases.
It generally includes two main parts as given below:. Test Closure : Test closure is basically a document that provides the summary of all the tests that are performed during SDLC. It gives full detailed analysis reports of the bugs that are discovered and removed. It is usually performed prior to the end of the testing process. Test scenario also called a scenario test, is defined as high-level detailed documentation of test cases or use cases.
In this, the tester tests the software application from an end-user perspective. It usually can serve as the basis for lower-level test cases or use case creation. Test scenario is also known as test condition or test possibility. It gives you an idea of what we need to test. Defect life cycle, also known as a bug life cycle, is a life cycle of various stages through which a defect goes during its whole lifetime. This life cycle starts as soon as the defect is discovered or reported by the tester and ends when the tester ensures that the defect is resolved and it won't occur again.
The defect life cycle includes the steps as shown below:. This type of testing is generally used in a low-risk system. There are four different experienced-based testing techniques as shown below:.
Smoke Testing: It is a type of testing performed to ensure that the acute functionalities of the program are working well. It acts as a confirmation of whether the quality assurance team can further proceed with testing or not.
Sanity Testing: It is an unscripted form of testing performed to ensure that the code changes that are made are working well. It is performed by the test team for some basic tests. This testing focuses on one or a few areas of functionality and is usually narrow and deep. Smoke vs Sanity Testing:. Pesticide paradox is basically a phenomenon where the more one tests the software, the more it becomes immune to its tests.
To overcome this, testers should always find new strategies, approaches, and test cases, so that they can identify bugs and resolve them. Configuration testing is a software testing technique that is used to evaluate the configurational requirements of the software. It discovers the optimal configuration of the system under which the application performs at its best, therefore configuration testing is considered important.
It also helps in identifying and resolving any compatibility issues. Software testing is an important activity that ensures quality, giving the confidence to release the software to customers. This article explained the testing process and its importance in software development.
It also covers important concepts on manual testing and will guide you to master the field of manual testing. However, testing is only a single component of a good software development strategy. A development team should use high coding standards, best practices, and patterns to reduce the bug count.
As a long-term strategy, the best way to improve the testing process is to test frequently, measure the results, gather feedback and use it to get better. The software testing that checks if the new code has broken the existing functionality is known as:. Before you go! Take this "Software Testing Interview Questions" interview guide with you.

It is a corrective technique. It is a proactive measure. It is a reactive measure. It is responsible for the full software development life cycle. It is responsible for the software testing life cycle. Example: Verification Example: Validation What is the difference between Verification and Validation? Verification Validation Verification is a static practice of verifying documents, design, code, black-box, and programs human-based.
Validation is a dynamic mechanism of validation and testing the actual product. It does not involve executing the code. It always involves executing the code. It is human-based checking of documents and files. It is computer-based execution of the program.
Verification uses methods like inspections, reviews, walkthroughs, and Desk-checking, etc. Validation uses methods like black box functional testing, gray box testing, and white box structural testing, etc. Verification is to check whether the software conforms to specifications. It can catch errors that validation cannot catch.
It can catch errors that verification cannot catch. Target is requirements specification, application and software architecture, high level, complete design, and database design, etc. Target is an actual product-a unit, a module, a bent of integrated modules, and an effective final product. Verification is done by QA team to ensure that the software is as per the specifications in the SRS document. Validation is carried out with the involvement of the testing team It generally comes first done before validation.
It generally follows after verification. It is low-level exercise. It is a High-Level Exercise. For more details, please refer to the following article Software Engineering — Verification and Validation. What is reverse engineering? Software Reverse Engineering is a process of recovering the design, requirement specifications, and functions of a product from an analysis of its code.
It builds a program database and generates information from this. The purpose of reverse engineering is to facilitate maintenance work by improving the understandability of a system and producing the necessary documents for a legacy system. Reverse Engineering Goals: Cope with Complexity. Recover lost information. Detect side effects. Synthesize higher abstraction. Facilitate Reuse.
For more details, please refer to the following article Software Engineering — Reverse Engineering. What is SRS? Software Requirement Specification SRS Format is a complete specification and description of requirements of the software that needs to be fulfilled for successful development of software system. These requirements can be functional as well as non-requirements depending upon the type of requirement.
For more details please refer software requirement specification format article. Distinguish between Alpha and Beta testing. Alpha Testing Beta Testing Alpha testing involves both white box and black box testing.
Beta testing commonly uses black-box testing. Alpha testing is performed by testers who are usually black,it -box internal employees of the organization.
Beta testing is performed by clients who are not part of the organization. Beta testing is performed at the end-user, the of the product.
Reliability and security testing are not checked in alpha testing. Reliability, security, and robustness are checked during beta testing. Alpha testing ensures the quality of the product before forwarding it to beta testing. Dynamic testing: To perform this testing the code is required to be in an executable form. Verification is a process of evaluating software at the development phase. It helps you to decide whether the product of a given application satisfies the specified requirements. Validation is the process of evaluating software at the after the development process and to check whether it meets the customer requirements.
Integration testing is a level of software testing process, where individual units of an application are combined and tested. It is usually performed after unit and functional testing. Test design, scope, test strategies, approach are various details that Test plan document consists of.
System Testing: System testing is finding defects when the system undergoes testing as a whole; it is also known as end-to-end testing. In such type of testing, the application suffers from beginning till the end.
UAT: User Acceptance Testing UAT involves running a product through a series of specific tests which determines whether the product will meet the needs of its users. Retesting: It is a process of checking bugs that are actioned by the development team to verify that they are fixed.
The application is tested with a different set of values. Test Scenarios: A Test Scenario is any functionality that can be tested. It is also called Test Condition or Test Possibility.
Test Cases: It is a document that contains the steps that have to be executed; it has been planned earlier. In other words a written set of steps that should be performed manually. Latent defect: This defect is an existing defect in the system which does not cause any failure as the exact set of conditions has never been met.
Phantom is a freeware and is used for windows GUI automation scripting language. It allows us to take control of windows and functions automatically. It can simulate any combination of keystrokes and mouse clicks as well as menus, lists and more. Test Deliverables are a set of documents, tools and other components that have to be developed and maintained in support of testing.
When the presence of one defect hides the presence of another defect in the system, it is known as fault masking. This will resolve the issue and hide the defect of unhandled exception firing. A test plan can be defined as a document describing the scope, approach, resources, and schedule of testing activities and a test plan should cover the following details.
It helps you to eliminate product risk in your project, and there is a simple yet crucial step that can reduce the product risk in your project. To get an expected test outcome, a standard procedure is followed which is referred to as Testing Type. SQA focusses more on the software process rather than the software work products.
It is a set of activities designed to make sure that the project manager follows the standard process. SQA helps test manager to benchmark the project against the set standards. RTM is prepared before test case designing. Requirements should be traceable from review activities. Test Matrix : Test matrix is used to capture actual quality, effort, the plan, resources and time required to capture all phases of software testing.
Traceability Matrix : Mapping between test cases and customer requirements is known as Traceability Matrix. Both stubs and drivers are part of incremental testing. In incremental testing, there are two approaches namely bottom-up and top-down approach.
Drivers are used in bottom-up testing and stub is used for a top-down approach. In order to test the main module, the stub is used, which is a dummy code or program.
The key words control the processing. It is also used for the visualization of data processing.
