在测试中将 @EnabledIf 与 Spring 环境中的 spring.profiles.active 属性一起使用

Question

根据文档(https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/test/context/junit/jupiter/EnabledIf.html#expression--)，您可以使用@EnabledIf注释 在测试类或测试方法上，如下所示：

@EnabledIf("${smoke.tests.enabled}")

或

@EnabledIf("#{systemProperties['os.name'].toLowerCase().contains('mac')}")

其中字符串是 Spring 环境中可用属性的占位符。

假设我有以下application.yml文件：

smoke:
tests:
enabled: true
spring:
profiles:
active: test

和以下测试类：

@EnabledIf(value = "#{${spring.profiles.active} == 'test'}", loadContext = true)
@SpringBootTest
public class SomeClassForTests {
@Autowired SomeType autowiredType;
@Test
public void someTest() {
// test logic...
}

当我运行测试时，出现以下错误：

Test ignored.

我对Spring表达式语言不太熟悉。 我到底做错了什么？

更新 1：

使用以下两个版本的批注：

@EnabledIf(value = "${spring.profiles.active == 'test'}", loadContext = true)

或

@EnabledIf(value = "#{spring.profiles.active == 'test'}", loadContext = true)

导致以下错误： org.junit.jupiter.engine.execution.ConditionEvaluationException: Failed to evaluate condition [org.springframework.test.context.junit.jupiter.EnabledIfCondition]: @EnabledIf("${spring.profiles.active == 'test'}") on class SomeClassForTests must evaluate to "true" or "false", not "${spring.profiles.active == 'test'}"

---

更新 2：

以下：

@EnabledIf(value = "${spring.profiles.active} == 'test'", loadContext = true)

导致以下错误：

org.junit.jupiter.engine.execution.ConditionEvaluationException: Failed to evaluate condition [org.springframework.test.context.junit.jupiter.EnabledIfCondition]: @EnabledIf("${spring.profiles.active} == 'test'") on class SomeClassForTests must evaluate to "true" or "false", not "test == 'test'"

更新3：答案：

@EnabledIf(expression = "#{environment['spring.profiles.active'] == 'test'}", loadContext = true)

当您只有一个活动配置文件时有效。当你有很多时，你会怎么做，如下所示：

smoke:
tests:
enabled: true
spring:
profiles:
active: 
- test
- someotherprofile

Answer 1

要从 SpringEnvironment中检查属性的确切值，您应该使用以下方法。

@EnabledIf(expression = "#{environment['spring.profiles.active'] == 'test'}", loadContext = true)

要检查哪些配置文件当前在 SpringEnvironment中处于活动状态，您应该使用以下方法。

@EnabledIf(expression = "#{environment.acceptsProfiles('test', 'someotherprofile')}", loadContext = true)

Answer 2

在 SpEL 中使用额外的撇号来包装属性：

@EnabledIf(value = "#{'${spring.profiles.active}' == 'test'}", loadContext = true)

当我尝试使用自定义属性时，我为我工作(终于！

Answer 3

您的表达式应如下所示：

@EnabledIf(value = "${spring.profiles.active == 'test'}", loadContext = true)
