In software engineering, code coverage, also called test coverage, is a percentage measure of the degree to which the source code of a program is executed when a particular test suite is run. A program with high code coverage has more of its source code executed during testing, which suggests it has a lower chance of containing undetected ...
NUnit is an open-source unit testing framework for the .NET Framework and Mono. It serves the same purpose as JUnit does in the Java world, and is one of many programs in the xUnit family. [ citation needed ]
Gcov is a source code coverage analysis and statement-by-statement profiling tool. Gcov generates exact counts of the number of times each statement in a program is executed and annotates source code to add instrumentation. Gcov comes as a standard utility with the GNU Compiler Collection (GCC) suite. [1]
NCover is a .NET code coverage tool. There are two non-related NCover products that do .NET code coverage. There is an open source NCover that can be found on SourceForge and there is a company called NCover, LLC. There has been additional development on both products since this 2004 reference.
Moq is a .NET Framework library for creating mock objects. It leverages C# 3.0 lambda expressions, typically used in Test Driven Development. MSTest: No: A command-line tool for executing Visual Studio created unit tests outside of the Visual Studio IDE - not really a testing framework as it is a part of the Visual Studio Unit Testing Framework.
While code integrity is usually achieved by unit testing the source code to reach high code coverage, it is definitely not the only way, or the best way, to achieve code integrity. In fact, code coverage, a popular metric to measure the thoroughness of unit tests, is known to have a limited correlation with the measure of real code integrity. [2]
The number of tests required based on the source code could be considerably different depending upon the coverage required, although semantically we would want to test both approaches with a minimum number of tests. [citation needed] Another example that could be considered as "cheating" to achieve higher MC/DC is:
The Visual Studio Unit Testing Framework describes Microsoft's suite of unit testing tools as integrated into some [1] versions of Visual Studio 2005 and later. The unit testing framework is defined in Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll.
