浓缩咖啡意向验证：“匹配0个意图”，但“已记录意图”

Question

我想简单地存根一个意图，该意图要求系统在用户单击按钮后以指定的URL打开网络浏览器

Intents.init()
val expectedIntent = allOf(hasAction(Intent.ACTION_VIEW), hasData(url))
intending(expectedIntent).respondWith(ActivityResult(0, null))

// here text view with link is clicked which will 
// launch browser to show web site
onView(withId(id)).perform(click())

intended(expectedIntent)
Intents.release()

运行测试时，我得到

junit.framework.AssertionFailedError: Wanted to match 1 intents. Actually matched 0 intents.

IntentMatcher: (has action: is "android.intent.action.VIEW" and has data: is <false>)

Matched intents:[]

Recorded intents:

很明显，该意图已启动但没有被打断，但是为什么？

也许我需要使用测试规则？但是，我正在隔离启动片段

@Before
fun init() {
    scenario = launchFragmentInContainer(null, R.style.Theme_AppCompat) {}
}

edit

测试规则是required？

也许我需要片段测试rule？

Answer 1

意图类型Intent.ACTION_VIEW的意图验证正在工作，这是导致故障的hasData方法。

我显然不需要任何测试规则。

Answer 2

由于您未指定url是什么，所以我只能猜测此参数与期望值不匹配。

如果您通过类似方式启动浏览器：

val url = "https://stackoverflow.com"
val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
startActivity(intent)

然后这在测试中可以很好地工作：

val url = "https://stackoverflow.com"
val expectedIntent = allOf(hasAction(Intent.ACTION_VIEW), hasData(url))
intending(expectedIntent).respondWith(Instrumentation.ActivityResult(0, null))

// perform click...

intended(expectedIntent)
