java - 检查 AlertDialog 的标题和消息

Question

使用 Espresso 是否可以简化这两个语句？

    onView(withText(expectedErrorTitle))
            .check(matches(isDisplayed()));
    onView(withText(expectedErrorMessage))
            .check(matches(isDisplayed()));

我试过这个，但它不起作用:

    onView(allOf(
            withText(expectedErrorTitle),
            withText(expectedErrorMessage)
    )).check(matches(isDisplayed()));

Answer 1

为什么还要简化？但是您可以检查父 View 是否有带有预期文本的 subview 。

onView(R.id.parentLayout)
  .check(matches(allOf(
    isDisplayed(), 
    withChild(withText("A")),
    withChild(withText("B"))
)));

检查父级是否显示就足够了，或者你做一些更疯狂的事情，比如

onView(R.id.parentLayout)
  .check(matches(allOf(
    withChild(allOf(withText("A"), isDisplayed())),
    withChild(allOf(withText("B"), isDisplayed())),
)));
