在测试时组合Application.properties文件

Question

I would like to know how can I append the content of all my Application.resources files into a single one when running the tests for my application?

Every time I run the tests, some configuration must be added from src/resources/Application.properties file to test/resource/Application.properties file.

How can I obtain this?

I am using Spring and Gradle

It can be done eg in the following way (there's a need to append main resources content to test resources file, keep old test resources for test execution, then swap the files):

apply plugin: 'java'

test {
   doFirst {
      def testRes = project.file('src/test/resources/test.resources')
      def mainRes = project.file('src/main/resources/main.resources')
      project.copy {
         from 'src/test/resources'
         into 'src/test/resources'
         include('test.resources')
         rename {
            'test.resources.old'
         }
      }
      testRes << '\n'
      testRes << mainRes.text

      logger.lifecycle('\nmain.resources text: ')
      logger.lifecycle(mainRes.text)
      logger.lifecycle('\ntest.resources text: ')
      logger.lifecycle(testRes.text)
      logger.lifecycle('\ntest.resources.old text: ')
      logger.lifecycle(project.file('src/test/resources/test.resources.old').text)
   }

   doLast {
      def testOldRes = project.file('src/test/resources/test.resources.old')
      testOldRes.renameTo(project.file('src/test/resources/test.resources'))

      logger.lifecycle('\nmain.resources text: ')
      logger.lifecycle(project.file('src/main/resources/main.resources').text)
      logger.lifecycle('\ntest.resources text: ')
      logger.lifecycle(project.file('src/test/resources/test.resources').text)
      logger.lifecycle("\ntest.resources.old exists: ${project.file('src/test/resources/test.resources.old').exists()}")
   }
}

In Spring you can import the data from existing resources. So basically, you need to create a Spring context file for your testing module and use the following tag to import the content of Application.properties from src/resources.

<import resource="src/resources/*.properties"/>
