Grails test-app fails while test-app individual unite test works - grails

Question

I have got a Grails 3.3.5 application with several Unit tests. While I run this tests individually they run as expected, but when I run a general test-app the tests fails with this message:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.grails.beans.ConstraintsEvaluator': Cannot resolve reference to bean 'grailsDomainClassMappingContext' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'grailsDatastore': Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.grails.datastore.mapping.simple.SimpleMapDatastore]: Constructor threw exception; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [java.util.Map<?, ?>]

Here's one of the unit test that works as expected when runned individually but fails with the global test:
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()
}
}
How can I solve this problems and run my tests together and not individually.
EDIT: I forgot to mention that I'm using two datasources, one default to save almost all the application data, and another one to save only 6 domains shared with another application.

Answer 1

Finally I've found a way to avoid the errors and run all the tests together. I must configure the datasource in all the tests using the doWithSpring closure.
First I made a Trait to configure the datasource using the applicationContext and the datasource name (if not given use the 'default' datasource):
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]
})
}
}
Next I must add the trait to all my tests and call the configDatasource with the application context and the datasource name, if it's not the default one.
Default datasource:
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
}
Another datasource:
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
}
