Ikokas Digital Technologies Interview Questions and Answers

Object-oriented programming (OOP) concepts are fundamental principles that help in designing and implementing software systems.

• Encapsulation: bundling data and methods together in a class

• Inheritance: creating new classes from existing ones

• Polymorphism: using a single interface to represent different types

• Abstraction: hiding unnecessary details and exposing only essential features

STLC stands for Software Testing Life Cycle, which is a process followed by QA teams to ensure quality software delivery.

• STLC involves planning, designing, executing, and reporting of tests.

• It includes various stages such as requirement analysis, test planning, test case development, test execution, and test closure.

• STLC helps in identifying defects early in the development cycle, reducing the cost of fixing them later...read more

Bug life cycle is the process of identifying, reporting, fixing, retesting, and closing a software bug.

• Bug is identified by tester

• Bug is reported to development team

• Development team fixes the bug

• Tester retests the bug

• If bug is fixed, it is closed

• If bug is not fixed, it is reopened

Get method retrieves data from a server while post method submits data to be processed by a server.

• Get method is used to retrieve data from a server while post method is used to submit data to be processed by a server.

• Get method appends data to the URL while post method sends data in the request body.

• Get method has a limit on the amount of data that can be sent while post method has no such limit.

• Get method is not secu...read more

SOAP and REST are two types of web service protocols used for communication between systems.

• SOAP (Simple Object Access Protocol) is a protocol used for exchanging structured information between systems using XML-based messages over HTTP or other transport protocols.

• REST (Representational State Transfer) is a protocol used for creating web services that allow communication between systems using HTTP requests and respons...read more

Test cases are specific conditions and inputs used to test a software application, while test scenarios are a series of test cases that simulate real-world usage.

• Test cases are designed to ensure that the software meets the requirements and specifications.

• Test scenarios are a collection of test cases that are used to test a particular feature or functionality.

• Test cases and scenarios are documented and executed to iden...read more

Traceability matrix is a document that links requirements to test cases to ensure all requirements are tested.

• It is used to track the relationship between requirements and test cases.

• It ensures that all requirements are covered by test cases.

• It helps in identifying any gaps in testing.

• It is a useful tool for project management and quality assurance.

• It can be created using a spreadsheet or specialized software.

• It is oft...read more

Validation is the process of evaluating a system or component during or at the end of the development process to determine whether it satisfies specified requirements. Verification is the process of evaluating a system or component to determine whether the products of a given development phase satisfy the conditions imposed at the start of that phase.

• Validation ensures that the product meets the customer's requirements...read more

Method overloading is a feature in object-oriented programming where a class can have multiple methods with the same name but different parameters.

• Method overloading allows a class to have multiple methods with the same name but different parameters.

• The methods must have different parameter types or a different number of parameters.

• The compiler determines which method to call based on the arguments passed to it.

• Example...read more

Method overriding is a feature in object-oriented programming where a subclass provides its own implementation of a method that is already provided by its parent class.

• Method overriding is used to achieve runtime polymorphism.

• The method signature of the overridden method in the subclass must match that of the method in the parent class.

• The access level of the overridden method in the subclass cannot be more restrictive...read more
