Study Notes
Software Testing - Visual Studio Debugging
- Visual Studio debugger is an integrated debugger
- Benefits of using it:
- Convenient
- Efficient
- Multi-variable Tracking
- Supports:
- Breakpoints (including conditional breakpoints)
- Stepping
- Stack trace
- Variable display
- Variable watch
Overview
- VS Debugger Overview
- Breakpoints
- Run Controls
- Variable Pane
- Watch Pane
- The Call Stack
Breakpoints
- Definition: A debugging technique to examine the state of code, examine variables during runtime, and allowing different execution paths
- Benefits:
- Examining the state of code
- Examining the state of all variables
- Changing variables during runtime
- Possibility of taking different paths within code using "Run Controls"
Breakpoint Types
- Conditional: Breakpoints hit only when a certain condition is met
- Tracepoint: A breakpoint used to output messages or execute macros
- Temporary: Break code only once
- Dependent: Breaks execution only after another breakpoint is hit first
Action Macros
- $CALLER: Displays the name of the calling function
- $CALLSTACK: Displays the call stack
- $FILEPOS: Displays the file name and line number of the breakpoint
- $FUNCTION: Displays the function name containing the breakpoint
- $TICK: Displays number of milliseconds since computer startup
- Example: "$FUNCTION called from $CALLER: i = {i}" indicates the function called from another
Breakpoint Pane
- Definition: A toolbox to show all breakpoints in one window
- Functionalities:
- Each breakpoint has a checkbox to temporarily disable it
- An "X" button to delete a breakpoint
- A "New" button to create different breakpoint types
Breakpoint Types
- Function breakpoint: The same breakpoint type used previously. Allows typing the function name to suspend execution on its first line
- Data breakpoint: Sets a breakpoint that watches for changes to a specific memory location.
Run Controls
- Continue: Executes until the next breakpoint is hit or the program completes
- Step Into: Executes the next statement, or enters a function
- Step Over: Executes the next statement but does not step into any functions
- Step Out: Steps out of a function. Executes until the function call returns.
- Stop: Stops the current program execution, and restarts it
- Terminates debugging session
Variables Pane
- Autos and Locals windows show variables during debugging.
- Autos: Displays variables around the current breakpoint
- Locals: Displays variables in the local scope
Watch Pane
- Used to watch variable and expression updates
- Displays multiple variables at once during debugging
- Shows any valid expression
The Call Stack
- Shows a sequence of function calls that lead to the currently paused line of code.
Exporting and Importing Breakpoints
- Breakpoints can be exported as an XML file. This facilitates saving and reusing sets of breakpoints. Making it easier to debug a specific issue if it reoccurs.
