Coverage with custom jacocorunner jar file - what am I doing wrong?

[pcj]

Trying to get coverage working for a repository after upgrading rules_scala to a40063ef97688f056824b22b9e49fae6efd1df0f and bazel 5.1.1.

[pcj]

Checked out rules_scala at 73f5d1a7da081c9f5160b9ed7ac745388af28e23 and built the custom deploy jar as follows:

I then edited the test.sh file to use the bazel 5 version:

 build_local_jacocorunner() {
-    $root_dir/scripts/build_jacocorunner/build_jacocorunner.sh
+    $root_dir/scripts/build_jacocorunner/build_jacocorunner_bazel_5.0+.sh
     cp /tmp/bazel_jacocorunner_build/JacocoCoverage_jarjar_deploy.jar $root_dir/manual_test/coverage_local_jacocorunner
 }

$ cd manual_test/coverage_local_jacocorunner
$ ./test.sh

With the custom jar built (all mvn tests passed), packed it into a zip file:

$ jar -cfM jacoco-coverage-73f5d1.zip ./JacocoCoverage_jarjar_deploy.jar

And uploaded that zip file here:

jacoco-coverage-73f5d1.zip

[pcj]

The zip file can be consumed as an http_archive as follows:

    http_archive(
        name = "rules_scala_jacocorunner",
        sha256 = "1e21d640ac5e39bff30c6255b2de389b0a53adf2338aeeeb5a656b13de11ba2b",
        urls = ["https://github.com/bazelbuild/rules_scala/files/10109719/jacoco-coverage-73f5d1.zip"],
        build_file_content = """
filegroup(
    name = "jar",
    srcs = ["JacocoCoverage_jarjar_deploy.jar"],
    visibility = ["//visibility:public"],
)
        """,
    )

[pcj]

A custom scala_toolchain was setup:

load("@io_bazel_rules_scala//scala:scala_toolchain.bzl", "scala_toolchain")

scala_toolchain(
    name = "jacocorunner_toolchain_impl",
    jacocorunner = "@rules_scala_jacocorunner//:jar",
    unused_dependency_checker_mode = "error",
    visibility = ["//visibility:public"],
)

toolchain(
    name = "jacocorunner_scala_toolchain",
    toolchain = "jacocorunner_toolchain_impl",
    toolchain_type = "@io_bazel_rules_scala//scala:toolchain_type",
    visibility = ["//visibility:public"],
)

[pcj]

The toolchain was registered in the WORKSPACE:

register_toolchains(
    "//bazel_tools/scala:jacocorunner_scala_toolchain",
)

[pcj]

Salient .bazelrc flags:

build --java_language_version=17
build --tool_java_language_version=17
build --java_runtime_version=remotejdk_17
build --tool_java_runtime_version=remotejdk_17

coverage --coverage_report_generator="@bazel_tools//tools/test/CoverageOutputGenerator/java/com/google/devtools/coverageoutputgenerator:Main"

[pcj]

Despite all this, coverage.dat files are always empty:

cc @gergelyfabian any suggestions here?

[gergelyfabian]

Did you try playing with the --instrumentation_filter parameter?

[gergelyfabian]

Please check https://github.com/gergelyfabian/bazel-scala-example. I've updated it to use Bazel 5.3.2 and Java 17.
On branch https://github.com/gergelyfabian/bazel-scala-example/tree/jacoco_coverage_fix_new I'm using a custom jacocorunner jar. Please try it by placing the custom built jar to tools/JacocoCoverage_jarjar_deploy.jar while using this repo and branch.

Tried with:

bazel coverage //...
lcov --list bazel-out/_coverage/_coverage_report.dat

[gergelyfabian]

rules_scala is on version 73f5d1a7da081c9f5160b9ed7ac745388af28e23 in my example.

[pcj]

Indeed things are working in that example, with the custom JacocoCoverage_jarjar_deploy.jar uploaded to this issue.

Clearly something different about the repository I'm using it within (not sure yet what it is) but at least this is a good sanity check so thank you @gergelyfabian for setting up this example.

[pcj]

Just leaving a trail here for my future self, or someone else... Seeing an exception from the jacocorunner, not sure what it means yet.

In the repo I'm working with, copying the example-lib/ into it and running coverage works for those simple targets. But running it for "real" targets always yields empty coverage.dat files.

Here's what I see with --test_env=VERBOSE_COVERAGE=1 flag:

bazel coverage \
  //common/utils/caseclass/... \
  --experimental_fetch_all_coverage_outputs \
  --instrumentation_filter=//common/utils/caseclass \
  --test_output=all \
  --experimental_split_coverage_postprocessing \
  --test_env=VERBOSE_COVERAGE=1 
  --spawn_strategy=standalone
