Introduction Unit testing is an important part of quality assurance in the process of software development. Unit tests can reduce the cost of software maintenance by reducing potential bugs in your code and making them discovered earlier. The quality of the software code is guaranteed by unit test, and the quality and efficiency of unit test cannot be neglected. Improving the quality and efficiency of unit testing not only makes software code more secure, but also saves time for developers to w

From: http://qa.taobao.com /? P = 7218 C/C ++ has very few statistical tools for code coverage. Compared with Java, there are very few open-source and free tools. It is very rare to use and open-source tools. Finally, we chose gcov-based lcov as the coverage rate statistics Tool for nginx testing. The reason for selecting lcov is simple: first, it is suitable for gcov as a test

The Code coverage is a tool that calculates the coverage of your unit tests. A high level of coverage gives you confidence in your unit tests and also shows that your application has been thoroughly tested. You may have written thousands of unit tests, but if the coverage is not high, then the test you write may not be

Document.stylesheets holds a collection of all the CSS rules on the current page. It allows you to traverse all selector defined in the page Here we just ask for the coverage of the CSS rules, so we can access Queryselectorall (). length. You can see each CSS usage by sorting. The code is simple. Copy Code code as follows: var usage = []; var sheets = document.stylesheets; for (var i = sheets.length-1 i!=-1; i--) {var rules =

(1) Interval full coverage problem Problem Description: Given an interval of length m, give the starting and ending points of n segments (note that this is a closed interval), and ask for a minimum number of segments to completely cover the entire range Example: Interval length 8, optional overlay segment [2,6],[1,4],[3,6],[3,7],[6,8],[2,4],[3,5] Problem Solving process: 1, each interval in accordance with the left endpoint increment order, af

The importance of journaling has been deeply rooted. But over time, the space occupied by the entire event log is expanding. To do this you need to set a maximum value for the log file to prevent it from taking up too much hard disk space. This is not only a waste, but it has created some obstacles to reading. And the importance of different log files is different. For this reason, the system administrator determines the maximum upper limit of each log file and the principle of log

As a tester, to ensure that the product software quality is its primary goal, in order to this goal, testers often through a lot of means or tools to ensure that coverage is one of the more important link. We typically divide test coverage into two parts, which are "requirements coverage" and "code coverage." Requireme

First, write in the topThis document is my previous period of work to summarize and share, oneself is also the first time to dabble in this knowledge, there must be omissions and deviations, and even "low-level error", so think of the role of the play, we share with each other, common progress. Can give a little inspiration to the work of the students, I am very satisfied.Second, what is coverage? What does it reflect? In short,

Testing for software, is to ensure the quality of an important process, and testing is divided into many kinds, unit testing, integration testing, system testing, stress testing, and so on, different test granularity and test objectives are different, such as unit testing focus on each line of code, integration testing is concerned about whether multiple modules can work together properly.When we measure the quality of the code, one of them is whether the code is unit-tested, how much is the tes

Wireless coverage for older wireless routers is not a force? now the price of high-power wireless products or dual-band wireless products is not cheap, and only one wireless router can not meet the needs of multi-family wireless coverage . So, is there any cheap and practical way to effectively expand your home's wireless network? The following is to int
