Testing Engineer Lead Interview Questions and Answers

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

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

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

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

• Primitive data types: int, float, double, char, boolean

• Non-primitive data types: arrays, classes, interfaces

• Derived data types: pointers, references

Software testing life cycle involves planning, designing, executing, and reporting on tests to ensure quality software.

• Planning phase involves defining test objectives, scope, and strategy.

• Design phase includes creating test cases, test data, and test environment setup.

• Execution phase involves running tests, recording results, and analyzing defects.

• Reporting phase includes documenting test results, defects, and overall quality assessment.
