Test coverage can be measured when Test cases are completed with certain percentage passed.
Common factors in deciding when to stop testing are:
Deadlines (release deadlines, testing deadlines, etc.) Test cases completed with certain percentage passed Test budget depleted Coverage of code/functionality/requirements reaches a specified point Bug rate falls below a certain level Beta or alpha testing period ends

Hi,
Test coverage is mesured by using RTM(Requirement Treceability Matrix).
Common factors in deciding when to stop are:
- Deadlines (release deadlines, testing deadlines, etc.)
- Test cases completed with certain percentage passed
- Test budget depleted
- Coverage of code/functionality/requirements reaches a specified point
- Bug rate falls below a certain level
- Beta or alpha testing period ends.

Through Traceability Matrix we can measure the test coverage.
In Test Plan, Exit Criteria specified when to stop testing
1) During the build release If Bug ratio comes down and there were zero critical and medium bugs
2) 100 % coverage is over as per the Test case document or Traceability Matrix
3) As per the Release Date mention in the agreement with client
4) Out of budget
5) When managers says stop testing
6) Alpha or beta testing is over

1) When the number of test cases are covered and how many passed and failed.
2) Bug flow rate is low or zero.
3) When more time is taken and its beyond the dead line.
4) More budget is consuming than what is planned.

Estimating the number of blackbox test cases:
# blackbox test cases =
[usecases x steps x rules]+[GUI‘s x objects x states]+[tables x tuples x instances]
Metrics for measuring test case coverage:
Requirements coverage =
tested requirements / specified requirements
Architectural coverage =
tested architectural features / architectural features
Code coverage =
tested statements, branches, paths, states / statements, branches, paths, states
Test case coverage =
Executed test cases / specified test cases
When to stop testing:
Stop testing when you've thoroughly tested all requirements and are satisfied with your architectural and code coverage.
