我正在尝试检查我在Kotlin中编写的测试用例的代码覆盖率。当我执行./gradlew createDebugCoverageReport --info
时,我的coverage.ec文件为空,我的报告显示我的覆盖率为0%。请注意,测试用例100%成功。任何人都可以想到我的coverage.ec文件不断返回0字节的原因吗?
我到处搜寻都没有运气。

通过为生成的.class文件定义两个不同的目录,您可以获得Java和Kotlin代码的逐行覆盖:
def debugTree = fileTree(dir: "${buildDir}/intermediates/classes/debug", excludes: fileFilter)
def kotlinDebugTree = fileTree(dir: "${buildDir}/tmp/kotlin-classes/debug", excludes: fileFilter)
然后,只需在classDirectories中包含两个fileTrees:
classDirectories = files([debugTree], [kotlinDebugTree])

几天后,我找到了解决这个问题的方法。对于那些遇到类似问题的人: 在您的intermediates文件夹中应该有一个tmp文件夹。该文件夹包含Kotlin文件的.class文件。如果您将fileTree(dir:“$ {buildDir} / intermediates / classes / debug”的路径(不包括:fileFilter)更改为这些类文件所在的位置,Jacoco将为您生成代码覆盖率!请注意,使用此方法,您将无法查看完整的逐行概述。
