Code coverage is a measure of how much code is executed in response to a stimulus (e.g. running a test). Test coverage is a measure of how much of the feature set was executed as a result of a test. Others will have other definitions. Test coverage is a measure of how many test cases have been executed during testing.Click to see full answer. Simply so, what is the difference between test coverage and fault coverage?Test coverage generally refers to how thorough the test program is compared against requirements. Fault coverage generally refers to how thorough functional test is. It is expressed in terms of percentage of nodes in the circuit exercised during functional test.One may also ask, what is an acceptable level of test coverage and why? Code coverage of 70-80% is a reasonable goal for system test of most projects with most coverage metrics. Use a higher goal for projects specifically organized for high testability or that have high failure costs. Minimum code coverage for unit testing can be 10-20% higher than for system testing. Accordingly, how do you test code coverage? Code coverage is a measurement of how many lines/blocks/arcs of your code are executed while the automated tests are running. Code coverage is collected by using a specialized tool to instrument the binaries to add tracing calls and run a full set of automated tests against the instrumented product.What is meant by test coverage?Amount of testing performed by a set of test cases is called Test Coverage. In other words, 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.
