これは、コンテキストライフサイクルを完了するために使用するスタック可能なトレイトとして実装されたバージョンです(必要に応じて、独自のメソッドbeforeAll()
とメソッドを持つことができます)。afterAll()
TestContextManager
他の投稿で提案されている生のソリューションを試しましたTestContextManager.prepareTestInstance()
が、コンテキストが閉じられていないことに気付きました。その結果、sbtコンソールを使用すると、テストを連続して実行するたびに副作用が発生し、ガベージが蓄積されます。
@ContextConfiguration(classes = Array(classOf[SomeConfiguration]))
class SomeTestSpec extends FlatSpec with TestContextManagement {
// Use standard Autowired Spring annotation to inject necessary dependencies
// Note that Spring will inject val (read-only) fields
@Autowired
val someDependency: SomeClass = null
"Some test" should "verify something" in {
// Test implementation that uses injected dependency
}
