带有Kotlin的Junit5测试套件

Question

基于此链接中的答案，创建了一个包含测试类的测试套件

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

返回错误

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

但是每个添加的测试类都有测试方法，并且单独运行

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

经过几天的检查，我找到了正确的libs，可以使用带有kotlin的JUnit5测试套件

在build.gradle中，添加2个库如下：

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

然后您可以使用测试套件如下：

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 2

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

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

Answer 3

现在，您可以完全使用jUnit 5引擎运行套件:

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< code > JUnit-platform-suite-engine :

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

这里有一些文档：
