Bazel: testng macro - bazel

Question

I'm trying to create a macro in Bazel to wrap java_test to run testng, however I'm running into trouble passing TestNG the filename
So far I have
load("#bazel_skylib//:lib.bzl", "paths")
def java_testng(file, deps=[], **kwargs):
native.java_test(
name = paths.split_extension(file)[0],
srcs = [file],
use_testrunner=False,
main_class='org.testng.TestNG',
deps = [
"//third_party:org_testng_testng"
] + deps,
args=[file],
**kwargs
)
However args seems to be a non-existent runfile.
Help appreciated on the correct value for args
Here is a sample usage I would like
java_testng(
file = "SomeFakeTest.java",
deps = [
"//:resources",
"//third_party:com_fasterxml_jackson_core_jackson_databind",
"//third_party:org_assertj_assertj_core",
],
)

Answer 1

Here is the solution I came up with
load("#bazel_skylib//:lib.bzl", "paths")
def java_testng(file, deps=[], size="small", **kwargs):
native.java_library(
name = paths.split_extension(file)[0] + "-lib",
deps = [
"//third_party:org_testng_testng"
] + deps,
srcs = [file]
)
native.java_test(
name = paths.split_extension(file)[0],
use_testrunner=False,
main_class='org.testng.TestNG',
runtime_deps = [
"//third_party:org_testng_testng",
paths.split_extension(file)[0] + "-lib"
],
data = [file],
size = size,
args=["-testclass $(location " + file + ")"],
**kwargs
)

I dont know why you used a macro, I manage to call testng without.
See my solution below:
I create my program jar (using some Annotation Processor)
I create my test jar (using some Annotation Processor)
I call testng via java_test().
The alone thing I didn't figure out: how to not hardcode the "libmy-model-test-lib.jar"
java_library(
name = "my-model",
srcs = glob(["src/main/java/**/*.java"]),
resources = glob(["src/main/resources/**"]),
deps = [
"#commons_logging_jar//jar",
":lombok",
":mysema_query",
...
],
)
java_library(
name = "my-model-test-lib",
srcs = glob(["src/test/java/**/*.java"]),
deps = [
"#org_hamcrest_core_jar//jar",
"#commons_logging_jar//jar",
":lombok",
":mysema_query",
...
"#assertj_jar//jar",
"#mockito_jar//jar",
"#testng_jar//jar",
],
)
java_test(
name = "AllTests",
size = "small",
runtime_deps = [
":my-model-test-lib",
":my-model",
"#org_jboss_logging_jar//jar",
"#org_objenesis_jar//jar",
"#com_beust_jcommander//jar",
],
use_testrunner=False,
main_class='org.testng.TestNG',
args=['-testjar','libmy-model-test-lib.jar','-verbose','2'],
)
java_plugin(
name = "lombok_plugin",
processor_class = "lombok.launch.AnnotationProcessorHider$AnnotationProcessor",
deps = ["#lombok_jar//jar"],
)
java_library(
name = "lombok",
exports = ["#lombok_jar//jar"],
exported_plugins = [":lombok_plugin"],
)
java_plugin(
name = "mysema_query_plugin",
processor_class = "com.mysema.query.apt.jpa.JPAAnnotationProcessor",
deps = [
"#querydsl_apt_jar//jar",
"#mysema_codegen_jar//jar",
"#javax_persistence_jar//jar",
"#querydsl_codegen_jar//jar",
"#guava_jar//jar",
"#querydsl_core_jar//jar",
"#javax_inject_jar//jar",
],
)
java_library(
name = "mysema_query",
exports = ["#querydsl_apt_jar//jar"],
exported_plugins = [":mysema_query_plugin"],
)
java_plugin(
name = "mockito_plugin",
processor_class = "",
deps = ["#mockito_jar//jar"],
)
java_library(
name = "mockito",
exports = ["#mockito_jar//jar"],
exported_plugins = [":mockito_plugin"],
)
