Test coverage is a measure of the percentage of 
requirements which have 
test cases associated with them. For example if you had ten requirements and only two of those had test cases associated with them then your test coverage would be 20%.Test coverage is measured for every 
project and then summarised into the 
programmes containing those projects.
