Coverage data is generated when the agent is tested

It seems like we might be able to generate some coverage with JaCoCo, but only for the tests run by gradle (i.e. with ./gradlew check integrationTest). This is only a small subset of our tests, of course -- nothing run by bats will generate any coverage.

We may be able to instrument the agent jar using OpenClover, and then configure it when bats runs.

首先运行所提到的 Gradle 检查和集成测试，然后检查 bats 如何运行 agent jar。将 ./gradlew check integrationTest 的 JaCoCo 覆盖率与提议的 OpenClover 插桩进行比较。当针对预期的测试路径（包括 bats）生成覆盖率，且不破坏现有测试命令时，即视为完成。
