Junit5 测试套件与 Kotlin

Question

根据 this link 中的答案，使用测试 classes

创建了一个测试套件

@RunWith(Suite::class)
@Suite.SuiteClasses(
    DTOtoEntityMapperTest::class,
    PostDataSourceCoroutinesTest::class,
    PostDataSourceRxJava3Test::class
)
class JUnit5TestSuite

Returns错误

org.junit.runners.model.InvalidTestClassError: Invalid test class 'com.x.DTOtoEntityMapperTest':
  1. No runnable methods

但是添加的每个测试 class 都有测试方法并单独运行，例如

class DTOtoEntityMapperTest {

    private val postDTOList by lazy {
        convertFromJsonToObjectList<PostDTO>(getResourceAsText(RESPONSE_JSON_PATH))!!
    }

    private val postEntityList by lazy {
        convertFromJsonToObjectList<PostEntity>(getResourceAsText(RESPONSE_JSON_PATH))!!
    }

    @Test
    fun `given PostDTO is input, should return PostEntity`() {

        val mapper = DTOtoEntityMapper()

        // GIVEN
        val expected = postEntityList

        // WHEN
        val actual = mapper.map(postDTOList)

        // THEN
        Truth.assertThat(actual).containsExactlyElementsIn(expected)
    }
}

Answer 1

对于 JUnit 5，我使用了 JUnitPlatform 和 SelectClasses（或 SelectPackages）：

@RunWith(JUnitPlatform::class)
@SelectClasses(Some1Test::class, Some2Test::class)
class SuiteTest

Answer 2

检查了几天后，我发现正确的库可以使用 Junit 5 测试套件和 kotlin

在build.gradle中，添加如下2个库：

testImplementation ("org.junit.platform:junit-platform-suite-api:1.7.0")
testImplementation ("org.junit.platform:junit-platform-runner:1.2.0")

然后您可以使用如下测试套件：

import org.junit.platform.runner.JUnitPlatform
import org.junit.platform.suite.api.SelectClasses
import org.junit.platform.suite.api.SelectPackages
import org.junit.runner.RunWith


@RunWith(JUnitPlatform::class)
@SelectClasses(BasicMockKUnitTest::class, HierarchicalMockKUnitTest::class)
@SelectPackages("exercise")
class TestAllSelectPackage {
}

Answer 3

您现在可以运行完全使用 jUnit 5 引擎的套件：

import org.junit.platform.suite.api.SelectClasses
import org.junit.platform.suite.api.Suite

@Suite
@SelectClasses(BasicMockKUnitTest::class, HierarchicalMockKUnitTest::class)
@SelectPackages("exercise")
class TestAllSelectPackage {
}

您必须导入 junit-platform-suite-engine:

https://search.maven.org/artifact/org.junit.platform/junit-platform-suite-engine

这里有一些文档：

https://junit.org/junit5/docs/snapshot/user-guide/#launcher-api-engines-custom https://junit.org/junit5/docs/snapshot/api/org.junit.platform.suite.engine/org/junit/platform/suite/engine/package-summary.html
