10+ S.a.v.e. Optics Interview Questions and Answers

Integration testing is a type of testing where multiple components are tested together to ensure they work as expected.

• Test cases should cover all possible combinations of inputs and outputs

• Test cases should include both positive and negative scenarios

• For an ATM, test cases should cover withdrawal, deposit, balance inquiry, and error scenarios

• Test cases should also cover integration with external systems such as the bank's database

Real-time scenarios involve testing software in a live environment with actual users and data.

• Identify potential issues that could arise in real-time usage

• Test software in a live environment with actual users and data

• Simulate real-world scenarios to ensure software functions as intended

• Monitor software performance and gather feedback from users

• Continuously test and improve software to ensure optimal performance

Our current project involves testing a web-based application using Agile methodology.

• We follow Agile methodology for testing

• Our project is a web-based application

• We use various testing tools such as Selenium, JMeter, and Postman

• We have a well-defined testing process in place

• We work closely with the development team to ensure timely delivery of quality software

Monkey testing is a random testing technique where the application is tested with random inputs to uncover unexpected bugs.

• Monkey testing involves randomly inputting data into the application to see how it responds.

• It is a form of ad-hoc testing where testers do not follow a specific test case.

• The goal of monkey testing is to find unexpected bugs that may not be caught by traditional testing methods.

• Examples of monkey testing include randomly clicking buttons, entering random...read more

Adhoc testing is informal testing without any predefined test cases or plans.

• Adhoc testing is performed randomly without any specific guidelines or documentation.

• It is usually done to explore the system and find defects that are not covered in formal testing.

• Adhoc testing is not structured and is based on the tester's intuition and experience.

• It can be performed at any stage of the development process.

• Example: Clicking on random buttons on a website to see if any unexpected b...read more

Encapsulation is the process of hiding implementation details and providing a public interface for accessing the functionality.

• Encapsulation is a fundamental concept in object-oriented programming.

• It helps in achieving data abstraction and information hiding.

• It allows for better control over the data and prevents unauthorized access.

• Example: A class in Java that has private variables and public methods to access them.

• Example: A capsule that contains medicine and has a protect...read more

Action Class is a class in Selenium WebDriver used to perform keyboard and mouse actions on a web page.

• Used to simulate user actions like click, double-click, drag and drop, etc.

• Can be used to handle pop-ups and alerts

• Can be used to perform keyboard actions like typing, pressing keys, etc.

• Can be used to perform mouse actions like moving the cursor, clicking, etc.

Regression testing is the process of retesting a software application to ensure that new code changes have not adversely affected existing functionality.

• Performed after code changes to ensure no new bugs have been introduced

• Helps maintain the quality and stability of the software

• Automated tools can be used to streamline the process

• Examples: running test cases after a software update, checking for bugs after adding new features

Functional testing is a type of software testing where the system is tested against the functional requirements/specifications.

• Tests the functionality of the software

• Focuses on what the system does

• Verifies that the system behaves as expected

• Does not concern with how the system works internally

• Examples: testing login functionality, search feature, data validation

One testing technique is boundary value analysis, which involves testing the boundaries of input ranges.

• Boundary value analysis involves testing the minimum and maximum values of input ranges.

• It helps identify errors at the boundaries of valid input values.

• For example, testing a program that accepts numbers from 1 to 100 by testing inputs of 0, 1, 100, and 101.

UI testing is the process of testing the user interface of a software application to ensure it meets the specified requirements.

• UI testing involves testing the visual elements of the application such as buttons, menus, and forms.

• It also includes testing the functionality of the UI elements such as navigation, input validation, and error handling.

• UI testing can be automated using tools such as Selenium and Appium.

• It is important to test UI on different devices and screen sizes...read more

Test case to verify the functionality of a lift/elevator system

• Verify that the lift/elevator responds to call buttons on different floors

• Check if the lift/elevator stops at the correct floor when requested

• Ensure that the doors open and close properly at each floor

• Test the emergency stop button functionality

• Verify the capacity of the lift/elevator by loading it with maximum weight
