Android Espresso made more fluent
Check out my blog 
or say hi on Twitter.
Overview
Cortado provides a layer of abstraction above Espresso, so it's a bit easier to use.
Remember: It is Google Espresso underneath. You can still mess up your tests the same way you would when using pure Espresso. Cortado just gives you a bit nicer way to communicate with Espresso.
Espresso vs. Cortado
- Get a
Matcherforclickableviews withR.id.textand with text NOT "Example"
| Framework | Code example |
|---|---|
| Espresso | Matchers.allOf(withId(R.id.text), isClickable(), Matchers.not(withText("Example")));
|
| Cortado | Cortado.view().withId(R.id.text).and().isClickable().and().not().withText("Example");
|
- Get a
Matcherfor views that have textexampleor have parentFrameLayout
| Framework | Code example |
|---|---|
| Espresso | Matchers.anyOf(withText("example"), withParent(isAssignableFrom(FrameLayout.class)));
|
| Cortado | Cortado.view().withText("example").or().withParent(isAssignableFrom(FrameLayout.class));
|
- Click on a
ViewwithR.id.button
| Framework | Code example |
|---|---|
| Espresso | Espresso.onView(withId(R.id.button)).perform(ViewActions.click());
|
| Cortado | Cortado.onView().withId(R.id.button).perform().click();
|
- Check if a
Viewwith textexampleis visible
| Framework | Code example |
|---|---|
| Espresso | Espresso.onView(withText("example")).check(ViewAssertions.matches(isDisplayed()));
|
| Cortado | Cortado.onView().withText("example").check().matches(isDisplayed());
|
- Replace a text on
enabledview withR.id.edit
| Framework | Code example |
|---|---|
| Espresso | Espresso.onView(Matchers.allOf(withId(R.id.edit),isEnabled())).perform(ViewActions.replaceText("changed"));
|
| Cortado | Cortado.onView().withId(R.id.edit).and().isEnabled().perform().replaceText("changed");
|
Features
-
Creating an instance of
org.hamcrest.Matcher<View>org.hamcrest.Matcher<View> matcher = Cortado.view().withId(R.id.example);
-
Creating an instance of
android.support.test.espresso.ViewInteractionViewInteraction viewInteraction = Cortado.onView().withId(R.id.example).perform(click());
-
Fluently creating
Matchers.allOf(...)Cortado.view().withId(R.id.example).and().withText("example").and().isClickable();
-
Fluently creating
Matchers.anyOf(...)Cortado.view().withId(R.id.example).or().withText("example").or().isClickable();
-
Fluently negating conditions
Cortado.view().not().withId(R.id.example).and().withText("example").and().not().isClickable();
-
Fluently performing single action (on
ViewInteraction)Cortado.onView().withId(R.id.example).perform().click();
-
Fluently checking matches (on
ViewInteraction)Cortado.onView().withId(R.id.example).check().matches(Cortado.view().withText("example"));
Compatibility
I wanted the api of Cortado to be compatible with Espresso as much as possible. That's why you can do stuff like that:
Espresso.onView(Cortado.view().withId(R.id.example).and().withText("Example")).perform(click());
