How to Test Server-side Kotlin 編
UbieではKotlin x SpringでAPI開発してます
テスト関係のフレームワークやライブラリ • JUnit5 - Jupiter • Spring Test - WebTestClient
• AssertJ • MockK • DbSetup-kotlin
JUnit5 class FooTest { @Nested inner class fooMethod { @Test
fun `should throw exception`() { assertThrows<MyException>() { Foo().foo() } } } }
class FooTest { @Nested inner class fooMethod { @Test fun
`should throw exception`() { assertThrows<MyException>() { Foo().foo() } } } } JUnit5
JUnit5 class FooTest { @Nested inner class fooMethod { @Test
fun `should throw exception`() { assertThrows<MyException>() { Foo().foo() } } } }
AssertJ val got = sut.findUser(id) assertThat(got).isNotNull assertThat(got?.name).isEqualTo("ほげ")
AssertJ val got = sut.findUser(id) assertThat(got).isNotNull assertThat(got?.name).isEqualTo("ほげ") Kotlin 1.3 Contractsで実現か!?
MockK interface UserRepository { suspend fun findUser(id: Long): User? }
val userRepo = mockk<UserRepository>() every { userRepo.findUser(1) } returns user
MockK interface UserRepository { suspend fun findUser(id: Long): User? }
val userRepo = mockk<UserRepository>() every { userRepo.findUser(1) } returns user coEvery { userRepo.findUser(1) } returns user
WebTestClient - expectBodyメソッド webTestClient.get() .exchange() .expectBody(MyApiBody::class.java) .isEqualTo<Nothing>(expectedBody) NullPointerException が出る!
WebTestClient - expectBody拡張関数 webTestClient.get() .exchange() .expectBody<MyApiBody>() .isEqualTo<Nothing>(expectedBody) import org.springframework.test.web.reactive.server.expectBody いける!
WebTestClient - expectBody拡張関数 webTestClient.get() .exchange() .expectBody<MyApiBody>() .isEqualTo<Nothing>(expectedBody) import org.springframework.test.web.reactive.server.expectBody いける!
が、サジェストされない
Pluginのバグ(issueあった)
しらじさん修正プルリク!!!神!!!!
リリースされるのは 1.3.20 乞うご期待
