KoinAppAlreadyStartedException:Koin应用程序已经启动 [英] KoinAppAlreadyStartedException: A Koin Application has already been started

问题描述

使用koin-2.0.1进行Android测试，尽管每个测试分别通过，但无法同时测试所有3个测试.

Using koin-2.0.1 for Android testing and unable to test all 3 test together though each test passes separately.

class NumberFormatterUtilImplTest : KoinTest {

    private val numberFormatterUtil: NumberFormatterUtilImpl by inject()

    @Before
    fun setUp() {
        startKoin { modules(utilsModule) }
    }

    @Test
    fun `does formatter returns two digit faction if supplied one digit value`() {
        val result = numberFormatterUtil.getAdjustedCurrencyRate(18.0)
        Assert.assertEquals(result, 18.00, 1.0)
    }

    @Test
    fun `does formatter returns two digit faction if supplied multiple digits value`() {
        val result = numberFormatterUtil.getAdjustedCurrencyRate(18.12343)
        Assert.assertEquals(result, 18.12, 1.0)
    }

    @Test
    fun `does formatter returns rounded two digit faction if supplied multiple digits value`() {
        val result = numberFormatterUtil.getAdjustedCurrencyRate(18.12876)
        Assert.assertEquals(result, 18.13, 1.0)
    }
}

正在运行的班级测试结果如下:

推荐答案

作为@After方法的替代方法，您也可以使用AutoCloseKoinTest.

As an alternative to the @After approach, you can also use AutoCloseKoinTest. As described in the docs:

扩展的Koin测试-嵌入自动关闭@after方法以在每次测试后关闭Koin

Extended Koin Test - embed autoclose @after method to close Koin after every test

您可以扩展AutoCloseKoinTest而不是扩展KoinTest，它将为您做事后测试.

Instead of extending KoinTest, you can extend AutoCloseKoinTest and it will do the after test for you.
