Infosys Automation Test Engineer Interview Questions, Process, and Tips

Check the password encryption by verifying the hashing algorithm used and comparing the encrypted password with a known hash value.

• Check the hashing algorithm used to encrypt the password (e.g. MD5, SHA-256)

• Compare the encrypted password with a known hash value for the same password

• Ensure that the encryption process is irreversible, meaning the original password cannot be easily obtained from the encrypted version

To get the URL of a webpage, you can use the window.location object in JavaScript.

• Use window.location.href to get the full URL of the webpage

• Use window.location.hostname to get the domain of the webpage

• Use window.location.pathname to get the path of the webpage

• Use window.location.protocol to get the protocol of the webpage (http or https)

One method to remove spaces in a string is by using the replace() method in JavaScript.

• Use the replace() method with a regular expression to replace all spaces with an empty string

• Example: str.replace(/\s/g, '') will remove all spaces from the string 'hello world'

• Another method is to use the split() method to split the string by spaces and then join the array elements without spaces

Handle popups by using automation tools, handling alerts, switching to popup windows, and using explicit waits.

• Use automation tools like Selenium to handle popups

• Handle alerts using switchTo().alert() method

• Switch to popup windows using switchTo().window() method

• Use explicit waits to ensure popup elements are loaded before interacting with them

Agile is iterative and flexible, while Waterfall is sequential and rigid.

• Agile involves continuous feedback and adaptation, while Waterfall follows a linear approach.

• Agile allows for changes throughout the development process, while Waterfall requires detailed planning upfront.

• Agile promotes collaboration and communication among team members, while Waterfall has distinct phases with limited interaction.

Use Selenium WebDriver to find all elements on a webpage using Java locators

• Use findElements method to locate all elements on the webpage

• Use By class to specify the locator strategy (e.g. By.xpath, By.id, By.className)

• Store the located elements in a List

Polymorphism is the ability of a function or method to behave differently based on the object it is called with.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• It enables a single interface to be used for different data types or classes.

• Examples include method overloading and method overriding in object-oriented programming.

An interface in programming is a contract that defines the methods that a class must implement.

• Interfaces in programming are used to define a set of methods that a class must implement.

• They provide a way to achieve abstraction and multiple inheritance in programming languages.

• Interfaces are used to define the behavior of a class without specifying how it is implemented.

• In languages like Java, classes can implement mult...read more

To create a left star pattern in Java, use nested loops to print stars in a left-aligned triangle shape. To run parallel test cases in automation testing, use TestNG's parallel attribute in the testng.xml file. TestNG annotations include @Test, @BeforeSuite, @AfterSuite, @BeforeTest, @AfterTest, @BeforeClass, @AfterClass, @BeforeMethod, @AfterMethod.

• For left star pattern in Java, use nested loops to print stars in a le...read more

Test cases are detailed steps to test a specific functionality, while test scenarios are high-level descriptions of possible test paths.

• Test cases are specific steps to test a particular functionality or feature.

• Test scenarios are high-level descriptions of possible test paths or user interactions.

• Test cases are detailed and concrete, while test scenarios are more abstract and general.

• Test cases are usually written in ...read more

Test closure is the final phase of the testing process where all testing activities are completed and the testing team evaluates the testing process.

• Test closure involves documenting the test results and preparing the final test closure report.

• It includes analyzing the test metrics to assess the quality of the testing process.

• Test closure also involves releasing the test environment and resources used during testing.

• It...read more

HTTP methods are actions that can be performed on a resource in API testing.

• GET - Retrieve data from a server

• POST - Submit data to a server

• PUT - Update an existing resource on a server

• DELETE - Remove a resource from a server

• PATCH - Partially update a resource on a server

Authentication verifies the identity of a user, while authorization determines what a user can access.

• Authentication confirms the user's identity through credentials like username and password.

• Authorization determines the user's permissions and access levels once authenticated.

• Authentication is the process of validating a user's identity, while authorization is the process of determining what actions a user is allowed ...read more

Python OOPS concepts include classes, objects, inheritance, polymorphism, and encapsulation.

• Classes are blueprints for creating objects with attributes and methods.

• Objects are instances of classes that can store data and perform actions.

• Inheritance allows creating new classes by inheriting properties and methods from existing classes.

• Polymorphism enables objects of different classes to be treated as objects of a common...read more

The pass, break, and continue keywords are used in programming to control the flow of execution in loops and conditional statements.

• The pass keyword is used as a placeholder for code that will be implemented later.

• The break keyword is used to exit a loop or switch statement.

• The continue keyword is used to skip the rest of the current iteration and move to the next iteration in a loop.

The task is to count the repetition of characters in a given string.

• Iterate through each character in the string

• Create a dictionary to store the count of each character

• If the character is already present in the dictionary, increment its count

• If the character is not present, add it to the dictionary with count 1

• Return the dictionary with character counts
