3.6 Debugging and Testing

• The purpose of debugging is to verify code correctness and performance.

  False
• Match the error type with its description:

  Syntax Error ↔️ Violates grammar rules

  Logic Error ↔️ Incorrect reasoning

  Runtime Error ↔️ Occurs during execution
• Testing verifies that code behaves as expected under different conditions.

  True
• What type of error occurs when code violates the programming language's grammar?

  Syntax error
• What is the primary focus of unit testing?

  Testing individual units
• What are the three main types of programming errors?

  Syntax, Logic, Runtime
• What happens during a runtime error?

  Program crashes or behaves unpredictably
• What does unit testing verify?

  Individual code units
• Steps for writing and running unit tests

  1️⃣ Choose a unit testing framework

  2️⃣ Write test cases

  3️⃣ Use assertion functions

  4️⃣ Run the tests
• What are the three categories of bugs in programming?

  Syntax, Logic, Runtime
• What is code review useful for in debugging?

  Catching obvious mistakes
• What is the primary purpose of debugging in programming?

  Fixing errors
• What is the goal of testing in programming?

  Verify code behavior
• Division by zero is an example of a runtime error.
• Debugging focuses on finding and fixing specific errors
• Match the error type with its example:

  Syntax Error ↔️ Missing semicolon

  Logic Error ↔️ Incorrect loop condition

  Runtime Error ↔️ Division by zero
• Integration testing verifies the interaction between different units of code.


  True
• Syntax errors occur when the code violates the programming language's rules
• Match the debugging technique with its description:

  Print Statements ↔️ Output variable values or program flow

  Debugger ↔️ Step through code line by line
• What does integration testing ensure?

  Units work together correctly
• Which unit testing framework is commonly used for Python?

  pytest
• Inserting print statements is a debugging technique called tracing.
• Tracing code involves inserting print statements at key points to monitor variable values and execution flow.
• Match the debugging strategy with its description:

  Code Review ↔️ Reviewing the code for errors

  Tracing ↔️ Using print statements to track variable values

  Debugger ↔️ Stepping through code line by line
• Debugging tools are used to identify the root causes of issues in code.


  True
• Match the type of error with its description:

  Syntax Error ↔️ Violation of language grammar

  Logic Error ↔️ Incorrect algorithm behavior

  Runtime Error ↔️ Error during program execution
• In Python, the `pdb` module is used to set a breakpoint in code for debugging.
• In unit testing, assertion functions are used to verify if the actual output matches the expected output.
• Code review is useful for catching obvious mistakes and improving code clarity
• A debugger allows programmers to step through code line by line and examine variables
• What are the three categories of bugs in programming?

  Syntax, logic, runtime
• What is the purpose of branching in source control systems?

  Experiment with new features
• Debugging and testing ensure code quality and reliability
• Debugging involves tracing code flow using debug tools
• Steps for debugging using print statements:

  1️⃣ Insert print statements at strategic points

  2️⃣ Execute the code

  3️⃣ Analyze the output

  4️⃣ Identify the error location

  5️⃣ Fix the bug
• Debuggers allow you to step through code and inspect values.
• The objective of integration testing is to ensure units work together.
• Logic errors result from incorrect reasoning or algorithms in the code.


  True
• A debugger allows you to set breakpoints
• Unit testing and integration testing complement each other to improve code reliability.
