To begin, make sure you’re familiar with the following prerequisites: You’ll write a unit test, add JaCoCo to your project, and automate the process using GitHub Actions. Implementing Code Coverage in Androidįirst, let’s walk through how to implement code coverage in your Android project. If you’d like, you can check out this tutorial’s GitHub repo. In this article, you’ll learn how to integrate JaCoCo, a free code coverage library in Java, into your Android project, then generate a report for analysis with Codecov. In short, knowing your percentage of code coverage, and what it means, can help you write better tests for your apps, which leads to building better apps. Codecov works in tandem with your continuous integration (CI) system to analyze every commit, so you get insight into how your tests are performing right in your own workflow. Reporting tools like Codecov can take your code coverage report and turn it into meaningful data, like how pull requests will affect code coverage. However, if I change the gradle task from simple-unit-test to compileKotlin (which will compile the code of my springboot api) it works with no trouble at all.ĭoes anybody have some direction for me? Any help would be greatly appreciated.You know testing your code is important-but how effective are your tests? How many lines of code does it address, and does it touch enough of the subroutines? Code coverage is the measurement of how much of your source code a test covers, and understanding it can go a long way toward being confident in your test results. So it appears that the test isn't even being run, and the gradle daemon explodes before it even gets that far! Gradle build daemon disappeared unexpectedly (it may have been killed or may have crashed) The result of github action running the test is - FAILURE: Build failed with an exception. Here is my workflow yaml file - name: Kotlin CI

That said, the test is just a standalone 'hello world' type unit test which lives in it's own module and of course has no problems when run locally (I'm using a custom gradle task to run it)! It's part of a gradle springboot project (a simple API microservice). I am trying to use a github action runner to run a test in my Kotlin project.
