| | Code coverage - Wikipedia, the free encyclopedia |
 | | However, there is no general-purpose algorithm for identifying infeasible paths (because such an algorithm could be used to solve the halting problem). | | | Code coverage techniques were amongst the first techniques invented for systematic software testing. | | | Techniques for practical path coverage testing instead attempt to identify classes of code paths that differ only in the number of loop executions, and to achieve "basis path" coverage the tester must cover all the path classes. |

| | Code Coverage Analysis |
| | This variation of path coverage considers only sub-paths that can easily be represented in the program source code, without requiring a flow graph [Woodward1980]. | | | As with data flow analysis for code optimization, pointers also present problems. | | | For example, variations distinguish between the use of a variable in a computation versus a use in a decision, and between local and global variables. |

| | In other systems the preparation of code coverage, during which time you determine which methods you will monitor, and the reporting part, where you analyze the results, are often performed by two different programs. | | | Even though code coverage analysis is a critical part of testing any significant software product, it is often so time-consuming in development environments before.NET that it is simply not done. | | | The code coverage environment is activated with a simple enable.bat file that registers the profiler and sets three shell variables. |

| | Testing and Code Coverage |
| | When using code coverage, as with every other part of the software engineering process, it is important to be pragmatic. | | | Using code coverage is a way to try to cover more of the testing problem space so that we come closer to proving the absence of faults, or at least the absence of a certain class of faults. | | | Given that the use of code coverage can find errors even in the specification, it makes sense to use it as early as possible in the development process. |

| | JavaRanch Journal - January 2004 - Introduction to Code Coverage |
| | Code coverage analysis could be implemented by having the virtual machine keep count of which parts of the loaded classes are executed. | | | The statement coverage measure is possibly the easiest to implement considering that it can be applied over bytecode, which is a lot simpler to parse than source code having a touch of human handiwork in it. | | | There are some variations to the path coverage measure that try to tackle this problem, mostly by simplifying the problem to a manageable size, for example by considering loops to have only two possible paths; zero or more rounds (or one or more in the case of do-while). |

| | Because of this overlap, code coverage analysis will soon be an integral part of optimizing compilers and will be provided as an option by major vendors. | | | In these optimizations, generic code on the critical path of the application is specialized to improve performance for a particular instance. | | | Presentation of Coverage Information The computing industry is seeing a widespread move toward distributed software development environments including offshore outsourcing to reduce costs. |

| | /* Rambling comments... */: Code coverage and testing |
| | The coverage data was useful; it clearly highlighted the code where we'd only written the first test and it also showed us where we had failed to add tests that executed various failure paths. | | | Often the untouched error situations were hard to get to; validation of input at one level in the code made it impossible for duplicated validation logic to fail lower in the code, but sometimes it's hard to see that... | | | Many of the classes that had pretty complete coverage had many of the exceptional code paths untouched; pass in an incorrect key to a factory object and it throws an exception, you need to remember to test for that. |

| | Chris Justus - Server Side Guy: 100% code coverage no guarentee... |
| | While code coverage is a great and noble goal we should all strive for, it is no guarentee that the code won't fail... | | | All of my examples had 100% code coverage, but were all capable of failing to various degrees - from throwing runtime exceptions to not evaluating 3 + 4.5 correctly... | | | I think there's a lot of software out there with segments of code that has not been executed by the developer before going out the door. |
