System Testing, sometimes called Functional Testing, is the process whereby organizations test an application to ensure that it is functionally correct. That is, that it will perform properly when used by the end user. This type of testing may be performed manually, or with the help of scripts. All organizations that develop software perform system testing prior to release. To learn more about Code Coverage Analysis visit:

Code Coverage Tools Can Eliminate Annoying Bugs Before the Customers Ever See the ProductAs a programmer it is frustrating to believe you have fully tested a program only to see it launch into the wild and see the bug reports start flying in. What did you miss? How could you have not seen the error in your code? Code coverage tools can help you find the bugs before the product shops. You can even do code coverage C programming analysis.What Exactly Do Code Coverage Tools Do?A code cover tool, or code coverage C toolbox, is a powerful testing environment. It allows you to design tests which will run a variety of tests through your program but with a unique twist.You probably already throw dozens of simulated tests at your software looking for bugs. You may have released Alpha or Beta versions to testers asking them to run it through the paces. You still have one problem which almost guarantees bugs will pop-up. You have no way of knowing if every single line of code in the program has been tested.A code coverage tool monitors your tests and records which lines of code has been tested. Tested code is highlighted in one color, where untested code stands out showing you where bugs may still be hiding.Using a Full Testing Environment Must Include Code CoverageThere are many great testing environments you can purchase, but not all of them include the line by line analysis of code coverage C. Your testing software needs to be able to setup simulated environments, run the tests, monitor results, and guarantee completeness of the test.If you cannot verify every sub-routine you have created has been tested how will you avoid those unpleasant support calls? How can you guarantee to your clients your software will not crash their system? Your reputation is on the line.


Are Code Coverage Tools Really Important Since Most Programmers Do Not Use Them?How important is your client base to you? Is your public reputation critical to the future success of your company? Is repeat business part of your business plan? Think about all the times you have seen software companies being blasted with negative press in magazines, by reviewers, and across social networks. With the fast proliferation of bad news which happens today quality control has become even more important. You cannot afford to have one small routine sitting off to the side which remains untested which could wreak havoc.Even if your program is not intended for mass distribution, imagine the complaints you will receive from your business client when they uncover a problem you missed. Even if you are only writing for your own company the screams from the department you wrote the software for will be loud, clear, and spread through the company like wildfire.The Cost of Quality is Small Compared to the Cost of FailureWhile in our minds a tiny sub-routine which fails is not paramount to the failure of the entire program end-users have a different perception. They expect flawless programs. You can deliver completely tested and flawless code only when you implement a quality program which uses code coverage tools. Using a code coverage C environment is the only sure method to make sure every single line of code has been thoroughly tested.
