## "Calculon never does two takes!"

Calculon is a testing DSL for Google Android. It allows you to write activity tests and user story tests using cool stuff like this:

    public class FooTest extends CalculonStoryTest {

        public FooTest() {

            super("com.example", FooActivity.class);

        }

        public void testFooAndBarStuff() {

            // direct assertion on current activity

            assertThat().inPortraitMode();

            assertThat().viewExists(R.id.launch_bar_button);

            // assert specific condition on current activity

            assertThat().satisfies(new Predicate() {

                public boolean check(Activity target) {

                    return target.isTaskRoot();

                }

            });

            // a view assertion that performs an activity check

            Activity barActivity = assertThat(R.id.launch_bar_button).click().starts(BarActivity.class);

            // other activity objects are also testable

            assertThat(barActivity).inLandscapeMode();

            // a direct view assertion

            assertThat(R.id.button_2).isVisible();

            // a view assertion that performs a check on another view

            assertThat(R.id.button_2).click().implies(R.id.launch_bar_button).isGone();

            // assert a specific condition on another view

            assertThat(R.id.button_2).click().implies(R.id.launch_bar_button).satisfies(

                new Predicate() {

                    public boolean check(View view) {

                        return view.getVisibility() == View.GONE;

                    }

                });

            // a key event assertion on an activity

            assertThat(barActivity).keyDown(KeyEvent.KEYCODE_X).finishesActivity();

        }

    }
