The world of technology is completely dominated by machines, and their behavior is controlled by the software running in it. Software testing is the best solution to all our worries about the machine’s behavior because they help the machine the exact way we want them to. Software testing is also stated as the process of verifying and validating a software product.
Software Testing is an activity to check whether the actual results match the expected results and also to ensure that the software system is Error free . It involves the execution of a software or system to develop defect free systems or software. Software testing role is to identify the errors, defects, or missing requirements in the actual requirements needed. Software Testing can be done manually or by using the automated tools.
Benefits of software testing:
The importance of software testing is considered as imperative. This process is skipped many times, therefore, the product and business might suffer due to this. To understand the importance of software testing, here are some key points that explain why your product should undergo software testing.
Some of the benefits of using software testing are listed below:
Cost-Effective: Testing any project on time helps you to save your money for the long term. In case of the bugs caught in the earlier stage of software testing, it only costs less to fix the problem.
Security: Security is the most vulnerable and sensitive benefit of software testing because people are looking for trusted products and software testing helps in removing risks and problems earlier.
Product quality: It is considered an essential requirement of any software product. Testing ensures a quality product is delivered to customers by the industry.
Customer Satisfaction: The main aim of any industry is to give satisfaction to their customers. UI/UX Testing ensures the best user experience and this is achieved by testing it properly.
Software Testing Interview Questions and answers:
1. What is Software Testing?
A set of activities conducted with the intent of finding errors in software is called software testing.
2. What is Acceptance Testing?
Testing conducted to enable a user or customer to determine whether to accept a software product is called acceptance testing. It is performed to validate the software meets a set of agreed acceptance criteria.
3. What is Accessibility Testing?
Verifying a product is accessible to the people having disabilities such as deaf, blind, mentally disabled etc is called accessibility testing.
4. What is Ad Hoc Testing?
Ad Hoc Testing is a testing where the software tester tries to break the system by randomly trying the system’s functionality.
5. What is Application Programming Interface (API)?
Application Programming Interface is termed as a set of software calls and routines which can be referenced by an application program in order to access supporting system or network services.
6. What is Backus-Naur Form?
Backus-Naur Form is a metalanguage used to formally describe the syntax of a language.
7. What is Beta Testing?
Testing of a release of a software product conducted by customers is known as beta testing.
8. What is Application Binary Interface (ABI)?
Application Binary Interface is termed as a specification for defining the requirements mainly for portability of applications in binary forms which are across the different system platforms and environments.
9. What is Binary Portability Testing?
Testing an executable application for portability across system platforms and environments is defined as Binary Portability Testing. It is usually for confirmation of an Application Binary Interface specification.
10. What is Black Box Testing?
Black Box testing based on an analysis of the specification of a piece of software without reference to its internal workings. The goal of the black box testing is to test how well the component conforms to the published requirements for the component.
11. What is Bottom Up Testing?
An approach to integration testing where the lowest level components are tested first, then used to facilitate the testing of higher level components is known as Bottom Up Testing. The process is repeated until the component at the top of the hierarchy is tested completely.
12. What is Boundary Testing?
Tests which focus on the boundary or limit conditions of the software being tested is known as Boundary Testing
13. What are the advantages of black box testing?
Testing from the end user’s point of view.
No knowledge of programming languages required for testing.
Identifying functional issues in the system.
Mutual independence in tester’s and developer’s work.
Helps to design test cases as soon as specifications are complete.
14. What is statement coverage?
White box testing involves the use of a metric called statement coverage to ensure testing of every statement in the software at least for once.
It is calculated as:
Statement Coverage = No. of Statements Tested / Total no. of Statements
15. What is Agile testing?
Agile testing is defined as an iterative and incremental testing process for the adaptability and customer satisfaction by rapid delivery of the product to the users. The product is broken down into incremental builds which are delivered iteratively.
These are some interview questions for manual testers asked in the interview process. Tester interview questions are mostly liked to be asked in all interviews and these interview questions for testing mentioned above are repeatedly asked.
As technology is growing faster, companies are in search of highly skilled employees. The company expects the employees must be strong in any one field. They recruit employees with additional skills gained along with their academics. The candidates must be an expert in any field to be hired in a company.
