With the new Android Studio 1.2, you are able to run your unit tests and see the coverage all within the IDE. First, you’ll need to get your unit tests running in the IDE. (if you already can, then skip this step) This guide and demo will help you. Secondly, you’ll need to create a … Read more
Property excludes of report goal specifies which files should be excluded from analysis during generation of report. In case of /path/tp/my/project/target/classes/META-INF/bundled-dependencies/some-third-party-1-jar-with-dependencies.jar@org/slf4j/event/EventConstants.class file is /path/tp/my/project/target/classes/META-INF/bundled-dependencies/some-third-party-1-jar-with-dependencies.jar , and the rest is about class in JAR file. Therefore as one of examples of correct configuration: <configuration> <excludes> <exclude>META-INF/**</exclude> </excludes> </configuration> As a proof having pom.xml <?xml version=”1.0″ encoding=”UTF-8″?> … Read more
Thanks for all the info on stackoverfow and CubicleMuses I have code coverage working for both simulator and device! Here are the steps and configuration that worked for me: Configuration : Xcode 4 ! XCode project settings Build Settings Other Linker Flags: add “-lgcov” GCC_GENERATE_TEST_COVERAGE_FILES: Set to YES GCC_INSTRUMENT_PROGRAM_FLOW_ARCS: Set to YES C/C++ Compiler Version: … Read more
Update 1: After reading a bit more about this, 2 things have now become clear to me (emphasis added): Tests and the tested application are compiled separately. Tests are actually injected into the running application, so the __gcov_flush() must be called inside the application not inside the tests. — Xcode5 Code Coverage (from cmd-line for … Read more
xdebug‘s code coverage tools allow you to test which lines of code are actually being executed, without needing to put trace statements in all of the functions/methods. Example: <?php xdebug_start_code_coverage(); function a($a) { echo $a * 2.5; } function b($count) { for ($i = 0; $i < $count; $i++) { a($i + 0.17); } } … Read more
Solved ! We have some C/C++ files with and without exceptions handling, so lcov/gcov process “exceptions handling” for each code block. Inside a normal block, for example: int main(void) { … … [+ -] printf(“Hello\n”); … } gcov reports that printf line has a “branch coverage” of 50% —> WHY ? Because exceptions handling is … Read more
You can get line-by-line coverage for both Java and Kotlin code by defining the two different directories for generated .class files: def debugTree = fileTree(dir: “${buildDir}/intermediates/classes/debug”, excludes: fileFilter) def kotlinDebugTree = fileTree(dir: “${buildDir}/tmp/kotlin-classes/debug”, excludes: fileFilter) Then, simply include both fileTrees in your classDirectories: classDirectories.from = files([debugTree], [kotlinDebugTree])
In a typical implementation the destructor usually has two branches: one for non-dynamic object destruction, another for dynamic object destruction. The selection of a specific branch is performed through a hidden boolean parameter passed to the destructor by the caller. It is usually passed through a register as either 0 or 1. I would guess … Read more
It took me a while and it also took me taking small snippets from a number of different sources and melting them together, but I think I have a small working example that sufficiently demonstrates to a Perl newbie the Perl build process including unit testing and code coverage analysis & reporting. (I’m using ActiveState … Read more
Designs like MVP and MVC typically try to abstract as much logic out of the actual GUI as possible. One very popular article about this is “The Humble Dialog Box” by Michael Feathers. Personally I’ve had mixed experiences with trying to move logic out of the UI – sometimes it’s worked very well, and at … Read more
