通常我们用 Tree Shaking 在编译时移除这些 dead code以减小代码体积。 2、冗余代码 而代码覆盖率里所提到的冗余代码 和 Dead Code 又略有不同,简单来说Dead code适用于编译时,而 Code coverage 适用于运行时。 Dead code 是任何情况下都不会执行的代码,所以可以再编译阶段将其剔除。 冗余代码 是某些特
检查是否插桩成功,可以在编译后的产物中搜索__coverage__,如果有则说明插桩成功。 为了紧密关联插桩代码的源代码,我们适配了各种provider,将环境变量发送到Canyon服务端,兑换到reportID,方便覆盖率数据聚合计算完成后的覆盖率源文件的关联展示。 我们还提供了babel-plugin-canyon的babel插件,可以在各种流水线内(aws,git...
对于浏览器环境,this就是window,而对于nodejs环境this就是global。 3. 生成报告(report) 这一步会依据全局标量中的覆盖率信息生成特定格式的报告,如html、lcov、cobertura、teamcity等。 一个样例 //source codefunctionabs(num){if(abs >0)returnnum;elsereturn-num; } //instrumented codevar__cov_iypKC$dWI6...
In addition, it will get much easier for a developer to navigate through the code of a suite with many tests. There are multiple alternative structures for the test suite that you may consider like given-when-then and RITE ❌ Otherwise: When looking at a report with a flat and long ...
覆盖率数据的来源是同一版本的代码,覆盖率数据是可以聚合的,Canyon内部使用reportID来关联测试用例和细分聚合维度。这样做可以让海量的覆盖率数据聚合成有限个,即Case的数量。 复制 /** * 合并两个相同文件的文件覆盖对象实例,确保执行计数正确。 * * @method mergeFileCoverage ...
JSLint, The JavaScript Code Quality and Coverage Tool. This file allows JSLint to be run from a web browser. It can accept a source program and analyze it without sending it over the network.
There’s astartPreciseCoverageendpoint that takes acallCountparameter. If that parameter is true V8 will count the number of times the code has run, rather than just giving a binary value. To generate the coverage report that’s shown at the top of this post we don’t need to count the...
Jtest allows you to speed up the Java-based applications development with minimum risk, proper guidance, and analysis. It is used for unit test and code coverage integrated with manual and automation testing. Its report provides a good picture of code covered and thereby minimizes risks. ...
