What is the difference between code coverage and functional coverage?
Code coverage means that you have verified all of the lines of code in the design. For example, if there is an if statement, you have checked both branches. Functional coverage is where you have verified all of the scenarios that the design is to be used.
What are the types of test coverage?
Two common forms of test coverage are statement (or line) coverage and branch (or edge) coverage. Line coverage reports on the execution footprint of testing in terms of which lines of code were executed to complete the test.
What is code coverage in unit testing?
Code coverage (or test coverage) shows which lines of the code were (or were not) being executed by the tests. It is also a metric which helps you to find out the percentage of your covered (executed) code by the tests. (It tells you nothing about the quality of your software or how good your tests are.)
How do you define test coverage?
Test coverage is defined as a technique which determines whether our test cases are actually covering the application code and how much code is exercised when we run those test cases. If there are 10 requirements and 100 tests created and if 90 tests are executed then test coverage is 90%.
What is UVM coverage?
Functional coverage is a measure of what functionalities/features of the design have been exercised by the tests. This can be useful in constrained random verification (CRV) to know what features have been covered by a set of tests in a regression.
Why do we measure code coverage?
Why Measure Code Coverage?
- To know how well our tests actually test our code.
- To know whether we have enough testing in place.
- To maintain the test quality over the lifecycle of a project.
What is code coverage and what are the different types of code coverage that one does?
Code Coverage vs. Functional Coverage
| Code Coverage | Functional Coverage |
|---|---|
| Code coverage tells you how well the source code has been exercised by your test bench. | Functional coverage measures how well the functionality of the design has been covered by your test bench. |
| Never use a design specification | Use design specification |
What is code coverage testing explain different types of code coverage?
Code Coverage testing is determining how much code is being tested. It can be calculated using the formula: Code Coverage = (Number of lines of code exercised)/(Total Number of lines of code) * 100% Following are the types of code coverage Analysis: Statement coverage and Block coverage. Function coverage.
