浓咖啡测试禁用动画 [英] Espresso testing disable animation

问题描述

@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())));

}

我在进行Espresso测试时遇到了一个问题，该测试涉及动画，我知道Espresso无法处理动画，所以我在下面做了。
-禁用我的测试设备窗口动画，过渡动画和动画师持续时间比例全部设置为OFF（这不起作用）
-然后我尝试在代码中添加一个标志。 espresso_testing = true。如果为true，则我的代码将跳过调用所有startAnimation（）函数的调用。 --->正常。但是，有一个要求，我在编写espresso测试用例时不能在应用程序上更改代码。包括上面的测试用例。

I encountered an issue on doing Espresso testing with a view involving animation, I know Espresso cannot deal with animation, so i did below. - disable my test device Window animation, transition animation and animator duration scale all set to OFF (this does not work) - then i tried to add a flag in my code eg. espresso_testing = true. if true, my code will skip calling all startAnimation() function call. ---> this is working. However, there is a requirement that I cannot change code on my app while writing espresso test case. Included a test case above.

还有其他方法吗？

推荐答案

请确保保持插件更新：

buildscript {
  repositories {
    google()
    gradlePluginPortal()
  }

  dependencies {
    classpath 'com.android.tools.build:gradle:3.3.0'
  }
}

在 testOptions 中使用名为 animationsDisabled ：

Use the new flag in testOptions called animationsDisabled:

android {

  ...

  testOptions {
    animationsDisabled = true
  }
}

您可以尝试在设备/仿真器上手动关闭动画：

我们强烈建议您在用于测试的虚拟或物理设备上关闭系统
动画。在
设备上的设置>开发人员选项下，禁用以下
3设置：

To avoid flakiness, we highly recommend that you turn off system animations on the virtual or physical devices used for testing. On your device, under Settings > Developer options, disable the following 3 settings:

窗口动画比例过渡动画比例动画时间
标度

Window animation scale Transition animation scale Animator duration scale

您可以通过命令行尝试使用 adb ：

You can try using adb via command line:

# Turn off animations
adb shell settings put global window_animation_scale 0 &
adb shell settings put global transition_animation_scale 0 &
adb shell settings put global animator_duration_scale 0 &

您可以尝试使用LinkedIn的 TestButler ：

You can try LinkedIn's TestButler:

TestButler.verifyAnimationsDisabled(InstrumentationRegistry.getTargetContext());

您可以尝试为浓缩咖啡创建 TestRule 和 Gradle 任务测试：

You can try creating a TestRule and Gradle task for your espresso tests:
