Find (B divided by A) multiplied by 100 this will be your test coverage .Thank you very much for your blog, it really nice explanation about the test coverage in software testing. it is helpful for doing study in testing. We aim for at least 70. On things that are more easily testable (functional data structures, for example), we aim for 90 and most individuals aim for as near to 100 as possible. On WPF-related things and other frameworks that are very difficult to test, we get much lower coverage (barely 70). There is danger in using a coverage measure.

Branch coverage is also called decision, arc or all edges coverage.So we are all enthused about using code coverage to help ensure that our software is well tested. Im looking for a process(es) to identify critical testing blocks in software.
100 code coverage is not a desirable goal. See this blog for some reasons. My best practice is to derive test cases from use cases. Basically, 100 code-coverage doesnt mean your code is perfect. Use it as a guide to write more comprehensive (unit-) tests.Code coverage is a measure used in software testing. It describes the degree to which the source code of a program has been tested. Lets begin with the base assertion of M. Martin, namely that 100 code coverage ensures that every code line behaves as intended.Point is, achieving 100 testing (and not 100 coverage) is overkill in most software. 100 coverage means test everything.

LCSAJ Linear Code Sequence and Jump. The IEEE Standard for Software Unit Testing section 3.1.2 specifies 100 statement coverage as a completeness requirement. Section A9 recommends 100 branch coverage for code that is critical or has inadequate requirements specification. In software testing, test coverage measures the amount of testing performed by a set of test. It will include gathering information about which parts of a program are actually executed when running the test suite in order to determine which branches of conditional statements have been taken. It is seldom practical to get 100 code coverage in a non-trivial system. Most developers who write unit tests shoot for the mid to high 90s.On the other hand, if people might die from errors in your software, then 100 statement coverage isnt enough. Designing your initial test suite to achieve 100 coverage is an even worse idea.Dont use code coverage in test design.

How does test coverage differ from fault coverage? I was reading discussions on software testing code coverage. The discussion was dominated by what the code coverage number for unit test or overall test are correct or desired. 40, 60, 80, even 100? some claims that google only requires 60 When it comes to software testing and code quality it is not always clear what the Test Coverage is respectively what areas of the application need more attention regarding testing.There we go, the test fails with a NullPointerException although we have 100 Code Coverage.
