如果没有robolectric，AndroidThreeTen无法在单元测试中工作吗?

问题描述

我无法在不需要robolectric的情况下创建单元测试.我在代码中使用AndroidThreeTen.init(this)，如果我禁用了robolectric，则在运行测试时出现错误:org.threeten.bp.zone.ZoneRulesException: No time-zone data files registered

I'm having trouble creating a unit test without needing robolectric. I am using AndroidThreeTen.init(this) in my code and when I run my test if I disable robolectric I get an error:org.threeten.bp.zone.ZoneRulesException: No time-zone data files registered

，如果我将其保持启用状态，则会显示以下内容:[Robolectric] com.mycomp.,yapp.utilities.log.LogTest.on Calling function w it returns an Int: sdk=28; resources=BINARY

and if I leave it enabled I get this:[Robolectric] com.mycomp.,yapp.utilities.log.LogTest.on Calling function w it returns an Int: sdk=28; resources=BINARY

我尝试使用testImplementation‘com.jakewharton.threetenabp:threetenabp:1.1.0’没什么区别.我在应用程序和testApplication中调用了AndroidThreeTen.init(this).有任何想法吗?这是我的考验

I have tried using testImplementation ‘com.jakewharton.threetenabp:threetenabp:1.1.0’made no difference. I have AndroidThreeTen.init(this) called in my application and testApplication. any ideas?this is my test

@Test
    fun `on Calling function i it returns an Int`() {
        assertThat("Returned class is not an Int", Log.i("Test", "Test"), isA(Int::class.java))
        assertThat("Returned Int is not 0", Log.i("Test", "Test"), `is`(0))
    }

还是因为这个原因我必须使用robolectric吗?(附带说明:日志不是来自android的util.log，而是我自己的类)(已编辑)

Or do I have to use robolectric because of this?(Side note: Log is not the util.log from android but my own class) (edited)

推荐答案

JVM单元测试不在Android运行时上运行.代替ThreeTenABP，您可以直接使用ThreeTenBP来为常规JVM初始化相同的API.

JVM unit tests don't run on Android runtime. Instead of ThreeTenABP, you can just use ThreeTenBP directly to get the same API initialised for a regular JVM.

在我的项目build.gradle中，我使用类似以下的设置:

In my project build.gradle I use a setup like:

implementation "com.jakewharton.threetenabp:threetenabp:${threetenabpVersion}"
testImplementation("org.threeten:threetenbp:${threetenbpVersion}") {
    exclude module: "com.jakewharton.threetenabp:threetenabp:${threetenabpVersion}"
}

其中

threetenabpVersion = '1.2.0'
threetenbpVersion = '1.3.8'

这通常通过ThreeTenABP使用ThreeTenBP，但是在单元测试配置中，它直接将TreeTenBP作为依赖项及其初始化代码添加.我不记得为什么要输入exclude规则了.已经有几年了.

This uses ThreeTenBP via ThreeTenABP normally, but in unit test configuration it adds TreeTenBP directly as a dependency, with its init code. Cannot remember exactly why I put in the exclude rule; it's been like that for a few years already.
