I try to pass parameters with gradlew command line, but can't. I successfully pass the Optional parameter with XML file, but need have the possibility to pass with gradle CMD

Gradle task:

    task task1(type: Test) {
        useTestNG() {
            suites './src/test/resources/testng/task1.xml'
        }
    }

XML:

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="test1">

    <test name="test1">
        <parameter name="ipAmount" value="20"/>
        <classes>
            <class name="tests.traffic.Test1"/>
        </classes>
    </test>

</suite>

Code:

    @Test(testName = "Name", description = "description")
    @Parameters({"ipAmount"})
    public void createTrafficTest(
            @Optional("1") Integer ipAmount
    ){
        final String IP_AMOUNT_PARAMETER = System.getProperty("ipAmount");

        System.out.println(ipAmount);//20
        System.out.println(IP_AMOUNT_PARAMETER);//null
    }

gradle CMD:

    gradlew clean task1 -DipAmount=2 

    gradlew clean task1 -PipAmount=2 

In both cases I get the same result: ipAmount=20, IP_AMOUNT_PARAMETER = null

How to correctly pass parameters from the gradle cmd?

CodePudding user response：

If your tests are being launched by the gradle JavaExec task then you can configure gradle to pass through its system properties like this:  

// The run task added by the application plugin
// is also of type JavaExec.
tasks.withType(JavaExec) {
    // Assign all Java system properties from
    // the command line to the JavaExec task.
    systemProperties System.properties
}

See the user guide for full details.

As explained also in the comment!

All you need to do is:

task task1(type: Test) {
systemProperties project.properties.subMap(["ipAmount"])
        useTestNG() {
            suites './src/test/resources/testng/task1.xml'
        }
    }

Then you can pass the property using gradlew clean task1 -PipAmount=2

Finally the systemProperties is a map so you can add more variables like ["ipAmount", "anotherParam", "moreParam"]
