12.5. Testing and Debugging the Application

Try these first

1. 1.

   Define unit testing in your own words.

   Hint

   Think about testing a single piece of software.

2. 2.

   What is integration testing?

   Hint

   It's about how the pieces fit together.

3. 3.

   What is the main purpose of unit testing?

   • To test the entire application
   • To test individual components
   • To handle errors

   Hint

   Think about testing pieces of code separately.

4. 4.

   True or False: Integration testing is only concerned with verifying the individual functions of a module.

   • True
   • False

   Hint

   Integration is about what happens when functions work together.

5. 5.

   You have developed a sensor reading function that sometimes provides erroneous data. Design a suite of unit tests that would help you identify the sources of these errors.

   Hint

   Think about all the inputs the function could receive.

6. 6.

   Reflect on an embedded system application you understand. Identify potential integration issues and propose ways to test for them.

   Hint

   Consider how each part interacts and what failures could occur.
