Question

如何使用布局背景的颜色进行espresso测试？目前使用hasBackground()：

onView(withId(R.id.backgroundColor)).check(matches(hasBackground(Color.parseColor("#FF55ff77"))));

但是错误发生了：

android.support.test.espresso.base.DefaultFailureHandler $ AssertionFailedWithCauseError：'具有可绘制ID的背景：-11141257'与所选视图不匹配。

预期：具有可绘制ID的背景：-11141257

得到：“LinearLayout {id = 2130968576，res-name = backgroundColor，visibility = VISIBLE，width = 996，height = 1088，has-focus = false，has-focusable = false，has-window-focus = true， is-clickable = false，is-enabled = true，is-focused = false，is-focusable = false，is-layout-requested = false，is-selected = false，layout-params = android.widget.LinearLayout $ LayoutParams @ e55f6e7，tag = null，root-is-layout-requested = false，has-input-connection = false，x = 42.0，y = 601.0，child-count = 2}“

我如何比较这个？

另一种方法是直接从View：

中检索颜色值

val bar = activityRule.activity.findViewById<View>(R.id.backgroundColor)
val actualColor = (bar.background as ColorDrawable).color
val expectedColor = Color.parseColor("#FF55ff77")
assertEquals(actualColor, expectedColor)

用“hasBackground”进行浓咖啡测试
