Software Testing and Quality Control Questions

Multiple choice

Acceptance Sampling is a type of quality control inspection where:

  1. All products are inspected

  2. A sample of products is inspected

  3. Destructive testing is performed

  4. Statistical methods are used to evaluate quality
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Acceptance Sampling is a quality control inspection method where a sample of products is inspected to determine if the entire lot meets the specified quality standards. This method helps reduce inspection costs and allows for faster decision-making.

Multiple choice

Which of the following is NOT a common type of Destructive Testing?

  1. Tensile testing

  2. Compression testing

  3. Fatigue testing

  4. Visual inspection
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Visual inspection is not a type of Destructive Testing. Destructive Testing involves subjecting a product or component to extreme conditions or forces to assess its durability and performance. Visual inspection is a non-destructive method used to identify defects or deviations from the specified standards.

Multiple choice

Which of the following is a common quality control technique?

  1. Sampling Inspection

  2. 100% Inspection

  3. Statistical Process Control

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sampling Inspection, 100% Inspection, and Statistical Process Control are all common quality control techniques used to ensure product quality.

Multiple choice

Which of the following is NOT a common type of environmental test for spacecraft?

  1. Thermal vacuum testing

  2. Vibration testing

  3. Acoustic testing

  4. Radiation testing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Acoustic testing is not typically performed on spacecraft, as they are not exposed to significant acoustic loads during their missions. The other three types of tests are commonly conducted to assess the spacecraft's ability to withstand the harsh conditions of space.

Multiple choice

  1. Electrical power system testing

  2. Propulsion system testing

  3. Attitude control system testing

  4. Thermal control system testing
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Propulsion system testing is not typically performed on spacecraft during functional testing, as it is a destructive test that can damage the spacecraft. The other three types of tests are commonly conducted to verify the functionality of the spacecraft's critical subsystems.

Multiple choice

Which of the following is NOT a common type of performance test for spacecraft?

  1. Orbit insertion testing

  2. Attitude control system testing

  3. Thermal control system testing

  4. Propulsion system testing
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Attitude control system testing is not typically performed on spacecraft during performance testing, as it is a functional test that is conducted to verify the functionality of the spacecraft's attitude control system. The other three types of tests are commonly conducted to evaluate the spacecraft's performance under various operating conditions.

Multiple choice

Which of the following is NOT a common type of acceptance test for spacecraft?

  1. Pre-launch testing

  2. In-flight testing

  3. Post-launch testing

  4. Ground testing
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In-flight testing is not typically performed on spacecraft during acceptance testing, as it is a performance test that is conducted to evaluate the spacecraft's performance in space. The other three types of tests are commonly conducted to verify that the spacecraft meets all of its specified requirements.

Multiple choice

Which of the following is NOT a common type of qualification test for spacecraft?

  1. Thermal vacuum testing

  2. Vibration testing

  3. Acoustic testing

  4. Radiation testing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Acoustic testing is not typically performed on spacecraft during qualification testing, as it is not a significant environmental factor that the spacecraft will encounter in space. The other three types of tests are commonly conducted to verify that the spacecraft can withstand the harsh conditions of space.

Multiple choice

  1. Pre-launch testing

  2. In-flight testing

  3. Post-launch testing

  4. Ground testing
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In-flight testing is not typically performed on spacecraft during protoflight testing, as it is a performance test that is conducted to evaluate the spacecraft's performance in space. The other three types of tests are commonly conducted to verify that the spacecraft meets all of its specified requirements.
