Invoking Testng

[abergmeier]

Description of the problem / feature request:

It is currently unclear how to tell TestNG how to test a (java) library.

Most straight forward approach would be:

java_test(
    name = "my-test",
    args = [
        "-testjar",
        "$(location :test_lib)", # Same problem with $(execpath :test_lib)
    ],
    main_class = "org.testng.TestNG",
    use_testrunner = False,
    runtime_deps = [
        ":test_lib",

This does not work an gives the error: label '//foo:test_lib' in $(location) expression is not a declared prerequisite of this rule.

How should one reference the runtime dependency instead?

What operating system are you running Bazel on?

Ubuntu 18.04.

What's the output of bazel info release?

release 1.2.1

You can add data = [":test_lib"]:

java_test(
    name = "my-test",
    data = [":test_lib"]
    args = [
        "-testjar",
        "$(location :test_lib)", # Same problem with $(execpath :test_lib)
    ],
    main_class = "org.testng.TestNG",
    use_testrunner = False,
    runtime_deps = [
        ":test_lib",

@sgowroji and @navca kindly help on this;

I have a test project, it is configured with maven and TestNG, it works perfectly fine with it. I want to use Bazel to run the same project. I have created WORKSPACE and BUILD files for each directory, which builds perfectly fine. I want to run the test using the 'testng_regressions.xml' in this direcotry: src/test/resources/testrunners/testng_regressions.xml

This is the BUILD file for 'testng_regressions.xml',

load("@rules_java//java:defs.bzl", "java_test")

java_library(
    name = "main_project_files",
    srcs = glob(['src/main/java/**/*.java']),
    runtime_deps = [
        "//Web/src/main/java/io/package/com/constants:app_constants",
        "//Web/src/main/java/io/package/com/factory:playwright_factory",
        "//Web/src/main/java/io/package/com/listeners:extent_report_listener",
        "//Web/src/main/java/io/package/com/pages:login_page",
        "//Web/src/main/java/io/package/com/steps:login_steps",
    ],
)

java_library(
    name = "test_project_files",
    srcs = glob(['src/test/java/**/*.java']),
    runtime_deps = [":main_project_files",
            "//Web/src/test/java/io/package/com/base:base_test",
            "//Web/src/test/java/io/package/com/tests:project_test_files"],
)
#
java_test(
    name = "testng_regressions",
    size = "small",
    timeout = "short",
    tags = ["regression"],
    runtime_deps = [
        ":main_project_files",
        ":test_project_files"
    ],
    use_testrunner = False,
    main_class='org.testng.TestNG',
    args=['-testjar','libtest_project_files.jar','-verbose','2'],
)

This is the content of the testNG file

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="Open Cart Test Regression PW Suite" thread-count="5"
       parallel="tests" verbose="4">
    <listeners>
        <listener class-name="io.christdoes.com.listeners.ExtentReportListener" />
    </listeners>
    <test name="Open Cart Home Page Test_chrome">
        <parameter name="browser" value="chrome" />
        <parameter name="language" value="en" />
        <classes>
            <class name="io.christdoes.com.tests.HomePageTest" />
        </classes>
    </test>
    <test name="Open Cart Login Page Test_safari">
        <parameter name="browser" value="safari" />
        <parameter name="language" value="nl" />
        <classes>
            <class name="io.christdoes.com.tests.HomePageTest" />
        </classes>
    </test>
</suite>

When I run the test, it always give a non-detailed error

@sgowroji , please kindly share the slack channel. I'll also post it as a new issue.
