Espresso Testing Framework - View Assertions

正如前面所讨论的那样,观点主张既要坚持实际观点(利用观点对等)又要说同样的看法。 样本代码如下:

onView(withId(R.id.my_view)) .check(matches(withText("Hello")))

这里

onView( <Interation, 表示与这一观点相符的物体。 ViewInteraction 采用对应观点进行互动。

withId(R.id.my_view) 浏览量等于id属性等于my_view。

T withextHello> 还将收到一种与(预期)案文属性等于Hello的观点相匹配的观点。

check是接受ViewAssertion论点并使用ViewAssertion标本的表述方法。

matches(withTextHello”) 退回一种观点主张,即实际观点(见with Id)和预期观点(见with Text)相同。

让我们学习抑制试验框架提供的一些方法,以表明对物体的看法。

doesNotExist()

一种观点主张,即确保观点匹配者不发现任何相匹配的观点。

onView(withText("Hello")) .check(doesNotExist());

这里 the test case ensures that there is no view with text Hello.

matches()

接受目标观点匹配者,并回复观点主张,确保观点匹配者(实际)存在,与目标观察者匹配。

onView(withId(R.id.textView_hello)) .check(matches(withText("Hello World!")));

这里 the test case ensures that the view having id, R.id.textView_hello exists and matches with the target view with text Hello World!

isBottomApgnedWith()

接受目标观点匹配者,并退回观点主张,以确保观点匹配者(实际)存在,并且与目标观察者匹配。

onView(withId(R.id.view)) .check(isBottomApgnedWith(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is bottom apgned with view having id, R.id.target_view.

isCompletelyAbove()

接受目标观点匹配者,并退回观点主张,确保观点匹配者(实际)存在,完全高于目标观察者。

onView(withId(R.id.view)) .check(isCompletelyAbove(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is positioned completely above the view having id, R.id.target_view

isCompletelyBelow()

接受目标观点匹配者,并退回观点主张,确保观点匹配者(实际)存在,完全低于目标观察者。

onView(withId(R.id.view)) .check(isCompletelyBelow(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is positioned completely below the view having id, R.id.target_view.

isCompletelyLeftOf()

接受目标观点匹配者,并退回观点主张,确保观点匹配者(实际)存在,完全脱离目标观点匹配者。

onView(withId(R.id.view)) .check(isCompletelyLeftOf(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is positioned completely left of view having id, R.id.target_view

isCompletelyRightOf()

接受目标观点匹配者,并退回观点主张,以确保观点匹配者(实际)的存在,并完全享有目标观点匹配者的权利。

onView(withId(R.id.view)) .check(isCompletelyRightOf(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is positioned completely right of the view having id, R.id.target_view.

isLeftApgnedWith()

接受目标观点匹配者,并退回观点主张,确保观点匹配者(实际)存在,并与目标观点匹配者保持一致。

onView(withId(R.id.view)) .check(isLeftApgnedWith(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is left apgned with view having id, R.id.target_view

isPartiallyAbove()

接受目标观点匹配者,并回复观点主张,确保观点匹配者(实际)存在,其地位部分高于目标观察者。

onView(withId(R.id.view)) .check(isPartiallyAbove(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is positioned partially above the view having id, R.id.target_view

isPartiallyBelow()

接受目标观点匹配者,并退回观点主张,以确保观点匹配者(实际)的存在,并部分低于目标观点匹配者。

onView(withId(R.id.view)) .check(isPartiallyBelow(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is positioned partially below the view having id, R.id.target_view.

isPartiallyLeftOf()

接受目标观点匹配者,并退回观点主张,确保观点匹配者(实际)存在,并且被部分置于目标观点匹配者的位置。

onView(withId(R.id.view)) .check(isPartiallyLeftOf(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is positioned partially left of view having id, R.id.target_view.

isPartiallyRightOf()

接受目标观点匹配者,并退回观点主张,确保观点匹配者(实际)存在,并部分享有目标观点匹配者的权利。

onView(withId(R.id.view)) .check(isPartiallyRightOf(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is positioned partially right of view having id, R.id.target_view.

isRightApgnedWith()

接受目标观点匹配者,并回归观点主张,确保观点匹配者(实际)存在,与目标观点匹配者保持适当一致。

onView(withId(R.id.view)) .check(isRightApgnedWith(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is right apgned with view having id, R.id.target_view.

isTopApgnedWith()

接受目标观点匹配者,并退回观点主张,确保观点匹配者(实际)存在,与目标观点匹配者保持高度一致。

onView(withId(R.id.view)) .check(isTopApgnedWith(withId(R.id.target_view)))

这里 the test case ensures that the view having id, R.id.view exists and is top apgned with view having id, R.id.target_view

noElppsizedText()

一种观点主张,即确保观点等级不包含略微或贬低案文观点。

onView(withId(R.id.view)) .check(noElppsizedText());

noMultipneButtons()

一种观点主张,即确保观点等级不包含多线纽扣。

onView(withId(R.id.view)) .check(noMultipneButtons());

noOverlaps()

一种观点主张,即确保可判读书的后代不相互重叠。 它有另一种选择,接受目标观点匹配者,并回归观点主张,确保后代认为与目标观点相匹配不会重叠。
