Q2. What are the testing comes in Destructive Testing of Concrete Specimens?

Ans.

Destructive testing of concrete specimens involves various types of tests to assess the strength and durability of the concrete.

  • Compression test: Measures the maximum load a concrete specimen can bear before failure.

  • Splitting tensile test: Evaluates the tensile strength of concrete by applying a diametrical load.

  • Flexural test: Determines the flexural strength of concrete by subjecting a beam specimen to bending.

  • Abrasion test: Assesses the resistance of concrete to wear and er...read more

Q3. What are the testing comes in Non Destructive Testing of Concrete Members?

Ans.

Non Destructive Testing (NDT) methods for concrete members include ultrasonic testing, rebound hammer test, and ground penetrating radar.

  • Ultrasonic testing is used to measure the thickness of concrete, detect voids, and assess the quality of concrete.

  • Rebound hammer test is used to determine the compressive strength of concrete by measuring the rebound of a spring-loaded hammer.

  • Ground penetrating radar (GPR) is used to detect embedded objects, such as reinforcement bars or voi...read more

Q4. What is the method to cut a cake into 8 pieces using only 3 cuts?

Ans.

To cut a cake into 8 pieces with 3 cuts, make two perpendicular cuts through the center of the cake.

  • Make the first cut horizontally through the center of the cake, dividing it into two equal halves.

  • Make the second cut vertically through the center of the cake, dividing it into four quarters.

Our framework is a hybrid framework combining data-driven and keyword-driven approaches for efficient and scalable testing.

  • Combines data-driven and keyword-driven testing

  • Allows for reusable test scripts and data separation

  • Supports automation of test cases with minimal coding

  • Enhances test coverage and scalability

  • Example: Using Excel sheets for test data and keywords for test actions

  • Inheritance allows classes to inherit properties and methods from other classes

  • Examples: String, Integer, List, HashMap

Q10. Difference between retesting and regression testing

Ans.

Retesting is testing the same functionality again to ensure the defect is fixed, while regression testing is testing the unchanged parts of the software to ensure new changes haven't affected them.

  • Retesting is done to confirm that a specific defect has been fixed, while regression testing is done to ensure that new changes have not affected the existing functionality.

  • Retesting focuses on the defect fixes, while regression testing focuses on the unchanged parts of the software...read more

Q11. What are all the data types

Ans.

Data types are classifications of data items that tell the compiler or interpreter how the programmer intends to use the data.
