To get data from a file in Selenium, we can use Java IO classes and read the file content.

• Create a File object with the file path

• Create a FileReader object with the File object

• Create a BufferedReader object with the FileReader object

• Use the BufferedReader object to read the file content line by line

• Close the BufferedReader object

Test case can be executed multiple times using automation tools or by manually running the test case.

• Use automation tools like Selenium or Appium to execute test cases multiple times.

• Create a loop in the automation script to execute the test case multiple times.

• Manually execute the test case multiple times by following the steps in the test case document.

• Use data-driven testing to execute the same test case with different input values.

• Use random testing to execute the test ca...read more

A test case can be excluded from execution by using tags or annotations.

• Add a tag or annotation to the test case with a specific value

• Configure the test runner to exclude test cases with that tag or annotation

• Use conditional statements in the test code to skip the test case based on certain conditions

Alpha testing and beta testing are two types of software testing performed before releasing the software to the public.

• Alpha testing is performed by the developers in-house, before releasing the software to external testers.

• Beta testing is performed by external testers, after the software has been released to a limited audience.

• Alpha testing is focused on identifying bugs and issues in the software, while beta testing is focused on gathering feedback from users.

• Alpha testing ...read more

Regression testing is testing the entire application after a change, while retesting is testing a specific bug fix.

• Regression testing is done to ensure that new code changes do not adversely affect existing functionality.

• Retesting is done to verify that a specific bug or issue has been fixed.

• Regression testing includes testing all the previously tested features to ensure they still work correctly.

• Retesting focuses on the specific bug or issue that was fixed.

• Examples of regres...read more

To find the maximum salary from the table and individual department in SQL.

• Use the MAX() function in SQL to find the maximum salary from the table.

• To find the maximum salary for each department, use the GROUP BY clause along with the MAX() function.

• You can also use the ORDER BY clause to sort the results in descending order and limit the output to only show the highest salary.

Program to extract digits from a string and add them together

• Iterate through each character in the string

• Check if the character is a digit using isdigit() function

• Convert the digit character to integer and add it to a running total

• Return the total sum of digits

Merge two strings diagonally in a Java array of strings.

• Iterate through each row and column to merge characters diagonally

• Keep track of the diagonal position to insert characters from both strings

• Handle cases where strings have different lengths

• Example: String 1: 'hello', String 2: 'world', Merged: 'hweolrllod'

• Example: String 1: 'abc', String 2: '123', Merged: 'a1b2c3'

Test case for weight vending machine to ensure accurate measurement and dispensing of items.

• Verify that the machine displays the correct weight of the item being measured.

• Test if the machine dispenses the correct amount of item based on the weight entered.

• Check if the machine recalibrates properly after dispensing multiple items.

• Ensure that the machine alerts the user if the weight measurement is inaccurate.

To debug a 500 error, check server logs, review code changes, test API endpoints, and use debugging tools.

• Check server logs for error details

• Review recent code changes that may have caused the error

• Test API endpoints using tools like Postman

• Use debugging tools like Chrome DevTools or Firebug

Browser history can be handled by clearing cache, cookies, and browsing data regularly.

• Regularly clear cache, cookies, and browsing history to improve browser performance

• Use incognito mode for private browsing to prevent history from being saved

• Disable browser history tracking if needed for privacy reasons

Program to reverse an array of strings

• Iterate through each string in the array and reverse it

• Use a temporary variable to swap characters at each end of the string

• Return the reversed array of strings

SRS stands for Software Requirements Specification and BRD stands for Business Requirements Document.

• SRS is a document that outlines the functional and non-functional requirements of a software system.

• BRD is a document that outlines the business requirements of a project.

• SRS is used by developers and testers to understand what needs to be built and tested.

• BRD is used by project managers and stakeholders to understand the business goals and objectives of a project.

• SRS includes...read more

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

• Bug identification by QA engineer

• Bug reporting with detailed steps to reproduce

• Bug fixing by development team

• Bug retesting to ensure it is resolved

• Bug closure after verification

Parallel test execution in Cucumber allows running multiple test scenarios simultaneously for faster results.

• Use tools like TestNG or JUnit to run Cucumber tests in parallel

• Configure the test runner to specify the number of threads to use for parallel execution

• Ensure that the tests are independent and do not interfere with each other

• Consider using a parallel plugin like Cucumber-JVM-Parallel to manage parallel execution

Zero sprint is a concept in Agile methodology where no new features are developed, focusing on bug fixes, refactoring, and technical debt.

• Zero sprint is a dedicated sprint where the team focuses on improving the quality of the existing codebase.

• During a zero sprint, no new features are added to the product.

• The team may work on bug fixes, refactoring, improving test coverage, addressing technical debt, and enhancing the overall quality of the software.

• Zero sprint helps in stab...read more
