Gcovr tool that shows C code coverage and related command examples
Recently, I accidentally found the gcovr tool online to show the code coverage rate of a unit test for a project. After using the tool, I thought it was quite good, so I wrote this article for reference by related developers.
In short, gcovr is a tool that shows code coverage in unit tests in a va
The development of wireless LAN has become increasingly mature. However, in this development, extensive coverage connections are not common. How can this problem be solved? Multi-AP wireless coverage will be a good solution.
Wireless LAN makes people feel relaxed and free. However, at present, this "freedom" is very limited. Most wireless LAN is confined to a small indoor space, and extensive
Jacoco IntroductionJacoco is an open-source coverage tool. Jacoco can be embedded in ant, Maven, and provide eclemma Eclipse plug-ins, or you can use javaagent technology to monitor Java programs. Many third-party tools provide integration of JACOCO, such as Sonar, Jenkins, and so on.Website address: http://www.eclemma.org/jacoco/Java CountersThe Jacoco contains coverage counters of various scales, includin
Gcov is a code coverage tool that can be used in C/s + +, and is a built-in tool for GCC. Here's how to use Gcov to collect code coverage information.To collect code overwrite information with Gcov, you need to add these 2 options "-fprofile-arcs-ftest-coverage" when GCC compiles the code, and compile this simple program

Software testing coverage includes branch coverage, statement coverage, and condition coverage. This is a basic test concept in white-box testing. However, I recently talked to several friends who have been conducting tests for many years, it is not clear to everyone. I will discuss this issue in depth through an examp
How to differentiate shapefile, coverage, and Geodatabase (reprinted) in the past 20 years, vector data models have seen the greatest changes in GIS. For example, each new software package developed by ESRI corresponds to a new vector data model. ARC/INFO corresponds to coverage, ArcView corresponds to shapefile, and ArcGIS corresponds to Geodatabase. Coverage an

The Code overwrites the CFG (Control Flow Graph) graph. The control flow chart (CFG) is a directed graph abstract data structure. It is an abstract representation of a process or program. Each node in the graph represents a basic block, for example, a straight line code block without any jump or jump target. The jump target starts with one block and ends with one block.
Aqtime coverage profiler has some good features, so that we can better detect code coverage.
New Area and files to ignore
When the target module is added, aqtime displays the object hierarchy of the module in a tree structure, such as the C/C ++ DLL, DLL --> OBJ --> API. If we only want to profile specific OBJ files, or exclude that the compilation tool adds its own OBJ files during compilation (because the
BackgroundThe project is using the small plugin.

Describes the importance of test code coverage
Test-driven Development (TDD) is an important feature of extreme programming, and it has many advantages and is accepted by more and more developers. During the test-driven development process, the programmer went through the process of writing test cases, implementing functions, and refactoring the code in a continuous iteration. Practice has shown that this process can significantly improve our product
-93 ~ due to floating signals ~ -The signal of 100 dBm will also go through several seconds after the original position is not moved.
2. Experiment verification of optimization parameters
According to the results of the current network parameter test, when the current network parameter is configured, the user will immediately switch to GSM after the call is initiated in most areas such as indoor, living room, and study rooms, the test results conform to the theoretical analysis.

[Wbia 1.4] records how to get the link, so you can easily get all URLs from this file. The basic idea of evaluating capture coverage is also very simple. Assume that the number of webpages I crawled is X and the total number of webpages is N, and the coverage rate is X/n. However, since N cannot be obtained, we need to use the sampling method. Random sampling from a webpage collection. Assume that the total

when I tried to investigate a defect, usually the first thing that I want to verify is the "RunTime" execution flow. and if the "RunTime" flow didn't match the "expected" flow, I wocould be very close to the root cause of a defect. however, sometimes it's not very easy to tell the "real/RunTime" execution flow (especially when you can't attach your debugger to the target assembly, or when the defect can't be reproduced stably ). I used to add more debug info output to the logs to help me out, an
In the previous discussion on code coverage, we have already talked about the defects of line coverage. However, row coverage is still widely used because it is simple enough. What surprised me is that as a commercial C ++CodeCoveragemeter, a coverage tool that explicitly states that row-based data overwrites are not p
