java_test: make it work for multiple junit tests and non tests sources without Skylark wrapper and dependent library

java_test rule doesn’t work as I would expect it should. I would expect to write this and provide mixed Junit tests and utility (also not tests classes) to the srcs glob.

Buck version:

  java_test(
    name = 'evict_cache_tests',
    srcs = glob(['src/test/java/**/*.java']),
  )

This doesn’t work. Instead, I need this Skylark wrapper to generate JUnit Suites for me: [1]. Even then, it doesn’t work because I must separate the utility library with non test sources from the JUnit test sources.

Bazel version:

load("//tools/bzl:junit.bzl", "junit_tests")

java_library(
    name = "evict_test_utills",
    srcs = glob([<non tests utility classes only>]),
)

junit_tests(
    name = "evict_cache_tests",
    srcs = glob(["src/test/java/**/*Test.java"]),# this would only pick test sources
    deps = [":evict_test_utills"],
)

Is there an update on this issue? Either a built in way in bazel, or an official skylark wrapper to generate test suites?

Voicing my support of this. Using bazel after coming from Gradle feels like 2 steps forward 1 step back. It’s debilitating trying to find what the “correct” way to do Java testing is in Bazel.

If possible, could this be raised to P2? Lack of testing support is the #1 blocker for me moving to Bazel.
