[英]How to mock android.util.Patterns with Mockito or MockK
I have a method that I need to test :我有一个方法需要测试:
fun validate(email: String): Result {
return if (android.util.Patterns.EMAIL_ADDRESS.matcher(email).matches()) {
Result(true)
} else {
Result(false, "error")
}
}
But it returns a NullPointerException
error because Patterns.email
needs to be mocked.但它返回一个
NullPointerException
错误,因为Patterns.email
需要被模拟。 Right now I manually create and test the Pattern but cannot test the method above.现在我手动创建和测试模式,但无法测试上述方法。
object Patterns {
private const val EMAIL_PATTERN = ("^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@" +
"[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$")
val EMAIL_ADDRESS: Pattern = Pattern.compile(EMAIL_PATTERN)
}
Any idea how to do this with Mockito or MockK so I can test this method as a whole instead of creating the patterns manually in the test.任何想法如何使用Mockito或MockK执行此操作,以便我可以整体测试此方法,而不是在测试中手动创建模式。
I believe you could use objectMockk
, from Mockk:我相信你可以使用
objectMockk
,从Mockk:
objectMockk(Patterns.EMAIL_ADDRESS).use {
every { Patterns.EMAIL_ADDRESS.matcher(email).matches() } returns true
//Code that uses the mock here
}
You're going to mock the constant field Patterns.EMAIL_ADDRESS
and then mock what you want it to return on the method matcher(email).matches()
.您将模拟常量字段
Patterns.EMAIL_ADDRESS
,然后模拟您希望它在方法matcher(email).matches()
。
I believe this is enough for your use case, but I'm not sure on how this lib is handled in Android.我相信这对于您的用例来说已经足够了,但我不确定这个库在 Android 中是如何处理的。
