Testing Interview Questions and Answers
Testing is actually defined to identify and improve the coding to improve its efficiency and make it bug-free.
Before we pen down all the details on web testing, let's quickly define what is web testing? In simple words checking your web application for possible bugs before it's made live or you can say that checking web application before the code is moved into the production department is called web testing.

These steps are involved to carry out the automation process:
- Select the testing tool
- State automation scope
- Plan, design and then develop
- Execute testing
- Maintenance; if any required
Certain conditions make automation testing useless for agile methods:
- When agile testing exhibits need of making changes in the requirement
- When comprehensive level of document submission is required
Here are some of the frameworks used in Software Automation Testing:
- Keyword driven automation
- Hybrid automation
- Modular automation
- Data-driven automation
These points should be considered:
- Assembly of sequential and uniform naming

- What are the limitation in the tool
It holds all the changes that foreign key make to the primary key. Delete Cascade rule has to be defined by the foreign key in order to serve the purpose.
It is a document that defines testing activity performance in a sequential manner. It is usually derived from SRS, Product Description and Case Document. Here are certain things that it covers: Reference, Items to be tested, Introduction, Software Issues and Risks, Testing of features, Schedules, Responsibility and Approvals.
It is the right set of Software and Hardware that are going to be used to perform the test.
Example:
For web application in Windows Operating system, IIS is the web server, Dot Net is the Web page Design, MS SQL server is Database and Chrome/Firefox/Internet Explorer is the Browser.
If you test the code, it helps you identify the error or defect (if any).
- Difficult to implement Exhaustive testing
- Early testing
- Bringing all the errors or defects together
- Pesticide Paradox
- Testing is done on the basis of context
- Reduce or finish fallacy error if there is any

| It doesn’t have separate index file. Instead, every key file passes through randomizer that defines the record in the database. | It is a separate index file with base as root segment. It has an information file that marks data position. |
Only one object is allowed by DBD in a specific time. For execution, when more than one object looks for permission, lock contention comes into action.
There are total three types of locks in mainframe:
- Update: It is known as permissive lock. It helps the program to read and make changes
- Shared: With the help of this lock, locked space reads two or more programs. It doesn’t allow the changes to take place
- Exclusive: It doesn’t let the locked space accessed.

A test case can have numbers of attributes according to the case requires, but these are the crucial ones which we mostly have with any test case: TestCaseId, Test Summary, Description, Prerequisite, Test Steps, Expected Results, Actual Results, Test Result, Automation Status, Date & Executed By.
Defect severity term is used to mention the severity of the defect impacting the functionality. Based on the organization, the defect severity can be mentioned in different levels, ranging from minor to critical or show stopper.
Usually priority – severity defects are divided into four categories, Low priority-Low severity, Low priority-High severity, High priority-Low severity, and High priority-High severity.
To example, these defect level: a spelling mistake in a page non-frequently navigated page will be categorized as Low priority-Low severity, whereas application crash in some very corner case will be defined as Low priority-High severity. For High priority-Low severity case example, brand name spelling mistake and logo colour change can be mentioned. And, login functionality issue can be categorized as High priority-High severity defect.
A bug that impacts the major functionality of an application and due to which the application can’t be delivered, can be defined as a critical bug. It’s different both in severity and characteristics compared to a blocker bug as it doesn’t block or affect the testing of other parts of the application.
Software Development Life Cycle or commonly known as SDLC refers to the all the activities performed during software development, such as the gathering of requirement, requirement analysis, coding, designing, implementation, testing, deployment and maintenance.
In testing, 100% automation would be tough to achieve because there would be several edge test cases and some of them are also executed seldom. Automating these types of cases which are not executed that often will not add value to the automation suite.

These type of information which are used very often and change as per the authorization and environment should always be maintained in a separate file. In case the user hardcore it into the code system, then the user has to change it in every file which has its reference.
Few of the good practices of automation testing will include:
- Adding appropriate comments
- Following the language-specific coding conventions
- Identifying the reusable methods and mentioning them in a separate file
- Run the scripts regularly
- Properly maintain the test data in a separate file
Yes, UI level testing is possible. But, we can do far from that. As early feedback is crucial for every testing project, we don’t need to wait until the UI layer gets developed. We can test the APIs directly, so that we can share crucial feedback early in the project development, giving developers more time to fix the bugs more proficiently.
We have to consider various factors while selecting an automation tool best suited to a project, such as:
- Required time to learn and implement the tool
- The application scope which we desire to automate
- Cost and budget management calculation
- Support available for the tool
- Limitations of the tool
