Description

$subject.

[lochana-chathura]

Defined a new task to execute the unit tests with semtypes activated.

// Define a new task for executing semtype_testng.xml separately
task semtypesUnitTest(type: Test) {
    systemProperty "java.util.logging.config.file", "src/test/resources/logging.properties"
    systemProperty "enableJBallerinaTests", "true"
    systemProperty "ballerina.experimental.semtype", "true"

    jvmArgs = ['-Xms512m', '-Xmx3g']

    useTestNG() {
        suites("src/test/resources/semtype_testng.xml")
    }

    afterSuite { suite, result ->
        result.exception?.printStackTrace()
    }

    testLogging {
        warn {
            events = ["failed", "skipped"]
            exceptionFormat "full"
        }
    }
}

Above is same as the below except for the one additional property ballerina.experimental.semtype.

ballerina-lang/tests/jballerina-unit-test/build.gradle

Lines 73 to 96 in 00b0687

	test {
	systemProperty "java.util.logging.config.file", "src/test/resources/logging.properties"
	systemProperty "enableJBallerinaTests", "true"
	jvmArgs = ['-Xms512m', '-Xmx3g']
	useTestNG() {
	suites 'src/test/resources/testng.xml'
	}
	afterSuite { suite, result ->
	result.exception?.printStackTrace()
	}
	testLogging {
	// this will only change --warn flag behaviour
	warn {
	events = ["failed", "skipped"]
	exceptionFormat "full"
	}
	}
	// dependsOn createBre
	}

However, when executing the former has less no of System.properties() causing the test runner to fail. e.g.
ballerina.home is not present in the former.
