Espresso Test Failed: Wanted to match 1 intent, Actually matched 2 intents

Question

I am getting this error while testing activity launch using espresso.

android.support.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: Wanted to match 1 intents. Actually matched 2 intents.

Surprisingly other activity launch tests with same code are getting passed.

@RunWith(AndroidJUnit4.class)
public class HomeActivityTest {

  @Rule
  public final IntentsTestRule<HomeActivity> mHomeActivityRule = new IntentsTestRule<HomeActivity>(HomeActivity.class);


  @Test
  public void testFundTransferActivityStarted() {

    onView(withId(R.id.button_fund_transfer)).perform(click());

    intended(hasComponent("mypackage.FundTransferActivity"));
 }

}

button click simply starts FundTransfer activity using startActivity.

Answer 1

Could you paste the full error message you got?

The error message would have the configuration of the 2 Intents matched as well. If both those intents have the same configuration, that means that you are calling startActivity twice, i.e, between test started and test ended. The below answer is for a specific case when you end up calling the same Intent twice.

Calling twice is a perfectly legitimate case. For instance,

Step 1: tap on Button1 to launch Gallery and pick a image and show in ImageView1 (initially ImageView1 is GONE and now it's VISIBLE).
Step 2: tap on ImageView1 to launch the Gallery again.

Now, If you wanted to test "Tapping on ImageView1 should launch Gallery", then you can't simply tap on ImageView1 since it's not visible initially. You need to first tap on Button1. If you do this, you need to Launch the Gallery twice.

Hence intended(hasComponent("mypackage.FundTransferActivity")); won't work. Instead use: intended(hasComponent("mypackage.FundTransferActivity"), times(2));
