Gradle

Resource links: Gradle user guide, Gradle forum on passing command line arguments
To run a test:
```
gradle test
```
To debug:
```
gradle test -Dtest.debug=true
```

To pass command line properties:

gradle test -Dsome.driver=firefox -Dsome.url=http://localhost/~selopre

To use the args in build.gradle:

  // all tasks of type 'Test' will call this
  tasks.withType( Test ) {
    systemProperties = System.getProperties()

    systemProperties['driver.options'] = 'chrome | firefox | htmlunit'
    systemProperties['url.options'] = 'selopre.com | http://localhost/~selopre'

    println 'passed from command line: '
    println 'some.driver=' + systemProperties['some.driver']
    println 'some.url=' + systemProperties['some.url']
  }

  // customize the test
  test {
    useTestNG()
  }

To use the args in a class:

@RunWith(MockitoJUnitRunner.class)
public class MyTest {
  @Test
  public void systemPropertiesTest() {
    String driver = System.getProperty("some.driver");
    String url = System.getProperty("some.url");
    Assert.assertNotNull(driver);
    Assert.assertNotNull(url);

    System.out.printf("BROWSER=%s%n", driver);
    System.out.printf("URL=%s%n", url);
  }
}
