13.4.1 Types of testing

• Regression testing is performed only once in the software development lifecycle.

  False
• Testing ensures the software is functional, accurate, and reliable
• What are the key purposes of testing in software development?

  Ensuring reliability and quality
• Match the type of testing with its purpose:

  Unit Testing ↔️ Checks individual components

  Integration Testing ↔️ Verifies interaction between components

  System Testing ↔️ Evaluates the entire system's functionality

  Acceptance Testing ↔️ Determines if the system meets user needs

  Regression Testing ↔️ Ensures new code changes don't introduce bugs
• Order the steps involved in black-box testing techniques

  1️⃣ Equivalence Partitioning

  2️⃣ Boundary Value Analysis

  3️⃣ Decision Table Testing
• White-box testing requires knowledge of the software's internal code structure.
• Testing in software development is crucial for ensuring software works correctly and finding errors or defects
• Testing verifies that software functions as intended according to its specifications.
• What does testing improve in software?

  Quality and performance
• Regression testing ensures that new code changes do not introduce new bugs
• What is the focus of black-box testing?

  Inputs and outputs
• Match the black-box testing technique with its explanation.

  Equivalence Partitioning ↔️ Tests one value from each class

  Boundary Value Analysis ↔️ Tests values at input boundaries

  Decision Table Testing ↔️ Ensures every rule is tested
• Boundary value analysis focuses on testing values at the edge of equivalence partitions
• What does decision table testing ensure in complex conditions?

  Every rule is tested
• What does white-box testing examine in software?

  Code structure and logic
• Match the white-box testing technique with its explanation.

  Statement Coverage ↔️ Tests every statement once

  Branch Coverage ↔️ Tests all possible branches

  Path Coverage ↔️ Tests all execution paths
• Statement coverage tests every statement in the code at least once.
• What does branch coverage ensure in if-else blocks?

  All branches are tested
• Regression testing is performed after each code change
• What is the primary goal of regression testing?

  Ensure no new bugs
• Regression testing is performed after each change
• Who typically performs acceptance testing?

  End-users or clients
• Grey-box testing uses partial knowledge of the code.
