  2. System testing

  3. Smoke testing

  4. Regression testing

Show answer
Correct Option: C
Explanation:

To answer this question, the user needs to know the different types of software testing.

The correct answer is:

C. Smoke testing

Explanation:

Smoke testing is a type of software testing that is used to check whether the most critical functions of a program are working correctly. The purpose of smoke testing is to determine whether the program is ready for additional testing. It is a quick and simple test that is performed before more comprehensive testing is done. The term "smoke testing" is derived from the idea of turning on a piece of hardware and seeing if it starts smoking. In software, smoke testing is used to determine whether the program will crash or fail catastrophically when run in its most basic configuration.

The other options are incorrect because:

A. Disaster testing: Disaster testing (also called "chaos testing" or "fault injection testing") is a type of software testing that involves creating controlled failures in order to see how well a system can withstand unexpected events.

B. System testing: System testing is a type of software testing that evaluates the functionality of a complete system. It is performed after integration testing and before acceptance testing.

D. Regression testing: Regression testing is a type of software testing that is used to verify that changes to a program have not introduced new bugs or broken existing functionality. It is typically performed after changes have been made to a program, to ensure that the changes did not have unintended consequences.

With thorough testing it is possible to remove all defects from a program prior to delivery to the customer.

technology testing

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

To solve this question, the user needs to be familiar with software development and quality assurance practices.

The statement is FALSE.

Thorough testing can help reduce the number of defects in a program, but it is not possible to completely remove all defects. There are several reasons for this, including the complexity of software systems, the difficulty of testing all possible scenarios, and the fact that defects can be introduced at any stage of the software development lifecycle. Additionally, testing can only identify defects that are visible under the specific test conditions used, and defects may still exist in untested code paths or under different environments.

Therefore, it is important to have a comprehensive testing process, in addition to other quality assurance practices such as code reviews and continuous integration, to identify and address defects as early as possible in the software development lifecycle.

The answer is: B. False

The goal of a software tester is to find bugs, find them as early as possible and make sure they get fixed.

Explanation:

To solve this question, the user needs to have knowledge of software testing concepts, specifically testing related to data conversion from existing systems to new systems.

Option A: Data driven testing is a type of testing where test input or output values are read from data files instead of using hardcoded values. This type of testing is not directly related to testing software used to convert data from existing systems to replacement systems.

Option B: Configuration testing is a type of testing that checks whether the software is properly configured according to the requirements. This type of testing is not directly related to testing software used for data conversion.

Option C: Migration testing is a type of testing that verifies the data and software functionality after migrating from the old system to the new system. This type of testing is directly related to testing software used to convert data from existing systems for use in replacement systems. Thus, option C is the correct answer.

Option D: Back to back testing is a type of testing where two identical systems are set up, and transactions are processed on both systems simultaneously to compare the results. This type of testing is not directly related to testing software used for data conversion.

Therefore, the answer is: C. Migration testing.
