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批注在这样的测试类或测试方法上：

@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

以及以下测试类：

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

    @Autowired SomeType autowiredType;

    @Test
    public void someTest() {
        // test logic...
    }

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。我到底在做什么错？

更新1：

使用以下两个版本的注释：

@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：

以下内容：

@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)

仅在一个活动配置文件时有效。当您有很多东西时，您将如何做？例如：

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

Answer 1

要检查Spring navigation.navigate('MainNavigator', {}, NavigationActions.navigate({ routeName: 'Requests' }))中某个属性的确切值，您应该使用以下方法。

navigation.navigate(NavigationActions.navigate({
       routeName: 'MainNavigator',
       action: NavigationActions.navigate({ routeName: 'Requests' })
      }))

要检查哪些配置文件在Spring Environment中当前处于活动状态，应使用以下方法。

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

Answer 2

您的表情应如下所示：

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

Answer 3

在SpEL中使用时，请尝试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（最后！）

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