Espresso testing disable animation

Question

@Test
    public void test3_PaySuccessful(){
        init();

    ViewInteraction amountEditText = onView(
            allOf(withId(R.id.et_amount), isDisplayed()));
    amountEditText.perform(replaceText("SGD 0.010"), closeSoftKeyboard());

    //, withText("Proceed")
    ViewInteraction appCompatButton = onView(
            allOf(withId(R.id.btn_confirm), isDisplayed()));
    appCompatButton.perform(click());

    //, withText("Pay")
    ViewInteraction appCompatButton2 = onView(
            allOf(withId(R.id.btn_confirm), isDisplayed()));
    appCompatButton2.perform(click());

    //dialog
    ViewInteraction appCompatButton3 = onView(
            allOf(withId(R.id.confirm_button), withText("Confirm"), isDisplayed()));
    appCompatButton3.perform(click());

    //have to disable animation in order to pass this.
    intended(CoreMatchers.allOf(hasComponent(PaymentSelectionActivity2.class.getName())));

}

I ran into a problem when testing Espresso with a view that included animation, I know that Espresso cannot deal with animation, so I did this below. - disable my test device. Window animation, transition animation, and animator animation duration are all set to OFF (this does not work) - then I tried to add a flag to my code, for example. espresso_testing = true. if true, my code skips the call to the startAnimation () function. ---> It works. However, there is a requirement that I cannot change the code in my application while writing an espresso test. The test case above is included.

Is there any other way to do this? Thanks in advance.

, :

buildscript {
  repositories {
    maven { url "https://plugins.gradle.org/m2/" }
  }

  dependencies {
    classpath "com.android.tools.build:gradle:2.3.1"
  }
}

testOptions, animationsDisabled:

android {

  ...

  testOptions {
    animationsDisabled = true
  }
}
