1.3.3. Test Coverage

Try these first

1. 1.

   What does test coverage refer to?

   Hint

   Think about what aspect of the testing process it evaluates.

2. 2.

   Define path coverage.

   Hint

   Consider what needs to be verified in a circuit.

3. 3.

   What is test coverage?

   • A measure of the number of tests run
   • The extent to which tests verify design correctness
   • The number of faults detected in a circuit

   Hint

   Think about what test coverage evaluates in testing.

4. 4.

   Path coverage tests all possible paths of a circuit.

   • True
   • False

   Hint

   Recall the definition of path coverage.

5. 5.

   Create a test suite for a simple digital circuit. Define how you would ensure both path and fault coverage in your tests.

   Hint

   Consider using specific input combinations to cover every logical transition.

6. 6.

   Analyze a given low-coverage test suite for faults found and not found. How would you improve it?

   Hint

   Focus on elements that were skipped and propose detailed tests.
