Infosys Interview Questions, Process, and Tips

I have worked on various projects involving test automation for web applications using Selenium and API testing using Postman.

• Developed automated test scripts using Selenium WebDriver for regression testing of web applications

• Created test suites and executed test cases using TestNG framework

• Performed API testing using Postman to validate response data and status codes

• Integrated test automation scripts with CI/CD pipeli...read more

API testing is a type of software testing that involves testing APIs directly to ensure they meet functionality, reliability, performance, and security requirements.

• API testing involves testing the functionality, reliability, performance, and security of APIs.

• It focuses on verifying the communication and data exchange between different software systems.

• API testing can be done at different levels such as unit testing, i...read more

Post is used to create a new resource, while patch is used to update an existing resource.

• Post is used to create a new resource in the server.

• Patch is used to update an existing resource in the server.

• Post request typically includes all the data needed to create the resource, while patch request only includes the data that needs to be updated.

• Post requests are idempotent, meaning multiple identical requests will have t...read more

Priority and severity are used to classify the impact and importance of a defect in software testing.

• Priority determines the order in which defects should be fixed, based on business needs.

• Severity indicates the impact of a defect on the system or users.

• Priority is usually set by the product owner or business stakeholders.

• Severity is typically determined by the testing team based on the impact on functionality.

Pricing procedure involves determining the cost of goods or services based on various factors.

• Consider factors such as production costs, competition, target market, and desired profit margin.

• Create a pricing strategy that aligns with the company's goals and objectives.

• Regularly review and adjust pricing based on market conditions and customer feedback.

• Examples: cost-plus pricing, value-based pricing, competitive pricin

Bug fixes are corrections made to software to address issues or errors that prevent it from functioning as intended.

• Bug fixes involve identifying and understanding the issue reported by users or testers.

• Developers then analyze the code to locate the source of the bug.

• Once the bug is identified, developers make the necessary changes to the code to fix the issue.

• Testing is done to ensure the bug fix works as intended and...read more

Item category determination involves assigning products to specific categories based on characteristics such as type, size, and function.

• Consider the type of product (e.g. electronics, clothing, food)

• Look at the size and dimensions of the product

• Take into account the function or purpose of the product

• Use a standardized classification system if available (e.g. UNSPSC, NAICS)

• Consult with team members or experts for input

Sort array without using methods

• Iterate through the array and compare each element with the rest to find the correct position

• Swap elements if necessary to sort the array in ascending order

• Repeat the process until the array is fully sorted

Reverse a string without using built-in methods

• Create an empty string to store the reversed string

• Iterate through the input string from the last character to the first

• Append each character to the empty string to reverse the input string

ngClass is used to conditionally apply CSS classes to an element in Angular.

• Use ngClass directive in the template with an object or array of classes and conditions

• Classes are applied when the condition is true, and removed when false

• Example:

Angular interceptors are a way to intercept HTTP requests and responses to perform operations like logging, modifying requests, or handling errors.

• Interceptors can be used to modify outgoing requests or incoming responses.

• They can be used for tasks like adding headers, logging requests, handling errors, or transforming data.

• Interceptors are implemented as services that implement the HttpInterceptor interface.

• Multiple i...read more

The entry point of Angular is typically the main.ts file.

• Main.ts file is the first file that is executed when an Angular application is started.

• It bootstraps the AppModule, which is the root module of the application.

• Main.ts file also imports other necessary modules and components required for the application to run.

A testing framework is a set of guidelines, coding standards, concepts, processes, practices, project hierarchies, modularity, reporting mechanisms, and tool support for writing automated tests.

• Provides a structure for organizing test scripts and test data

• Offers reusable functions and libraries for common testing tasks

• Helps in generating test reports and managing test execution

• Supports integration with other tools and

Java code to identify duplicates in a given string

• Convert the string into an array of characters

• Use a HashMap to store each character and its frequency

• Iterate through the array and check if the character already exists in the HashMap

• If it does, increment the frequency count, if not, add it to the HashMap

• Finally, iterate through the HashMap and print out the characters with frequency greater than 1
