 Code Coverage
Today we will talk about code coverage tools which are used by
developers for measuring the quality of the software testing. There are so
many different types of code coverage tools, some are basics and others
that are exceptionally thorough.
But before going further on tools let's first see what is Code Coverage?

 Code Coverage
Code Coverage is a methodology, which is performed to measure and describe
how much the source code of a program is executed when a specific test suite runs.
It gives a percentage score to a program which defines as a high code coverage and
low code coverage. If it gets high percentage of code coverage during testing's
which means it has a minimal chance of containing undiscovered software bugs in
the comparison of a program which scored low percentage of code coverage while
testing.

In simple words , code coverage is
performed to check whether your tests
are really analyzing your code or not.
With code coverage, one can tell the
amount of your code is being tested by
running the test.

 Where to use ?
Code coverage tools can be performed on
.NET, Java, Visual C/C++ and Visual Basic
applications.

 Benefits of Code Coverage
Dead Code Identification - The first and the major
benefits of code coverage is that after running this test
you will get the outputs that shows those functions
which are not called, after detecting that you can
identify whether the code is untouched as no required
use case exists or code is dead code (i.e. not required).

Quality Assurance - Quality of a product or application is one of the major
concern in software world and this can be done by measuring the report after
running the code coverage. Higher the amount of coverage better will be the
quality of product or application and lesser is the chance to have defects.
Missing test Identification - It can be beneficial in identifying the
extra tests (exceptional cases), which are missed out earlier after
running the test suites analysis report.

 Top Tools
This is the real challenge to choose which code coverage tools to
use for application testing. I also thought about it and after few
hours research on the internet and with the help of Google trend I
shortlisted my results and pick top 5 code coverage tools.
Now the next question here is which code coverage tools to
choose ?

 Top Tools
Cobertura is one of the most used and best code coverage tools. This is a free
Java tool that calculates the percentage of code accessed by tests. It can be
used to identify which parts of your Java program are lacking test coverage. It
is based on jcoverage. It is easy to use and can measure coverage without
having the source code. It's represents reports in HTML or XML format, It has
capacity to test lines and branches of class and method.

JaCoCo is also an open source free code coverage tools for Java, which has been
made by the EclEmma group in view of the lessons gained from utilizing and
joining existing libraries for a long time. JaCoCo offers instructions, line and
branch coverage. It can instrument off-line and on-the-fly and It fully supports
Java 7 and Java 8. It also has capacity to test lines and branches of class and
method. It also provide very nice and easy to navigate HTML or XML report.

dispersed per-test coverage and many instrument integration; it is by
and large effectively created and supported.

NCover is a code coverage tool for .Net programs and applications. It
supports statement coverage and branch coverage. It is also very
easy to use and fast tool which is available on open source and as
well as on commercial license. This tool can perform manual as well
as automated code coverage tests and it provides nice and attractive
multiple testing environments.

Testwell CTC++ is a code coverage tool for C and C++ but it also can be used for Java
and C#. The development of this tool is belongs to Testwell which lately acquired by
Verifysoft Technology GmbH for C and C++. This tool can check Statement Coverage,
Function Coverage, Decision Coverage, Multicondition Coverage, Modified
Condition/Decision Coverage (MC/DC), Condition Coverage. This is also in the
category of user-friendly and fast tools. It finds missing test cases smoothly. It
provide reports on XML format.
