我有一个带有多个单元测试的 Grails 3.3.5 应用程序。当我单独运行此测试时，它们按预期运行，但是当我运行一般测试应用程序时，测试失败并显示以下消息：

这是单独运行时按预期工作但在全局测试中失败的单元测试之一：

package my.package

import grails.testing.gorm.DomainUnitTest
import spock.lang.Specification

class CapituloSpec extends Specification implements DomainUnitTest<Capitulo> {

    void "test id cannot be null"() {
        when:
        domain.id = null

        then:
        !domain.validate(['id'])
        domain.errors['id'].code == 'nullable'
    }

    void "test titulo cannot be null or blank"() {
        when:
        domain.titulo = null

        then:
        !domain.validate(['titulo'])
        domain.errors['titulo'].code == 'nullable'

        when:
        domain.titulo = ''

        then:
        !domain.validate(['titulo'])
        domain.errors['titulo'].code == 'blank'
    }

    void "test titulo maxSize"() {
        when: "titulo is 101 characters length"
        domain.titulo = 'a' * 101

        then: "titulo validation fails"
        !domain.validate(['titulo'])
        domain.errors['titulo'].code == 'maxSize.exceeded'

        when: "titulo is 100 characters length"
        domain.titulo = 'a' * 100

        then: "titulo validation succeed"
        domain.validate(['titulo'])
    }

    void "test capitulo ok"() {
        when:
        domain.id = 1
        domain.titulo = "Test"

        then:
        domain.validate()
    }
}

我怎样才能解决这个问题并一起而不是单独运行我的测试。

编辑：我忘了提到我正在使用两个数据源，一个默认保存几乎所有应用程序数据，另一个只保存与另一个应用程序共享的 6 个域。

最后，我找到了一种避免错误并一起运行所有测试的方法。我必须使用doWithSpring闭包在所有测试中配置数据源。

首先，我使用 applicationContext 和数据源名称创建了一个 Trait 来配置数据源（如果没有给出，则使用“默认”数据源）：

package my.package

import groovy.transform.CompileStatic
import org.springframework.context.ConfigurableApplicationContext
import org.springframework.core.convert.support.ConfigurableConversionService
import org.springframework.core.convert.converter.Converter

@CompileStatic
trait MultiDatasourceTest {

    def configDatasource(ConfigurableApplicationContext applicationContext, String datasource = "default") {
        System.setProperty("grails.gorm.connections", datasource)

        ConfigurableConversionService conversionService = applicationContext.getEnvironment().getConversionService()
        conversionService.addConverter(new StringToMapConverter())
    }
}

class StringToMapConverter implements Converter<String, Map> {
    @Override
    Map convert(String source) {
        source.split(",").collectEntries({
            [(it):it]
        })
    }
}

接下来，我必须将特征添加到我的所有测试中，并configDatasource使用应用程序上下文和数据源名称（如果它不是默认名称）调用。

默认数据源：

package my.package

import grails.testing.gorm.DomainUnitTest
import org.springframework.context.ConfigurableApplicationContext
import spock.lang.Specification

class CapituloSpec extends Specification implements DomainUnitTest<Capitulo>, MultiDatasourceTest {

    @Override
    Closure doWithSpring() {
        return {
            configDatasource(application.mainContext as ConfigurableApplicationContext)
        }
    }

    void "test id cannot be null"() {
        when:
        domain.id = null

        then:
        !domain.validate(['id'])
        domain.errors['id'].code == 'nullable'
    }

    // More tests
}

另一个数据源：

package my.package

import grails.testing.gorm.DomainUnitTest
import org.springframework.context.ConfigurableApplicationContext
import spock.lang.Specification

class DocumentoTeoSpec extends Specification implements DomainUnitTest<DocumentoTeo>, MultiDatasourceTest {

    @Override
    Closure doWithSpring() {
        return {
            configDatasource(application.mainContext as ConfigurableApplicationContext, "sede")
        }
    }

    void "test numeroExpediente cannot be null or blank"() {
        when:
        domain.numeroExpediente = null

        then:
        !domain.validate(['numeroExpediente'])
        domain.errors['numeroExpediente'].code == 'nullable'

        when:
        domain.numeroExpediente = ''

        then:
        !domain.validate(['numeroExpediente'])
        domain.errors['numeroExpediente'].code == 'blank'

        when: "numeroExpediente is 21 characters long"
        domain.numeroExpediente = 'a' * 21

        then: "numeroExpediente validation fails"
        !domain.validate(['numeroExpediente'])
        domain.errors['numeroExpediente'].code == 'maxSize.exceeded'

        when: "numeroExpediente is 20 characters long"
        domain.numeroExpediente = 'a' * 20

        then: "numeroExpediente validation succeed"
        domain.validate(['numeroExpediente'])
    }

    // More tests
}
