title: Enable spring datasource only for ONE test
body: <p>I have a project so big in which only 3 tests in a class uses a datasource connection, and this connection is optional, so I am interested in only enable the datasource connection by spring in this test.</p>
  <p>Looking for the Spring manual I see the option properties = {} in @SpringBootTest to enable some properties and I thought to enable here,</p>
  <pre><code>@SpringBootTest(classes = Application.class, webEnvironment = WebEnvironment.RANDOM_PORT, properties = {
      &quot;spring.datasource.url=[url]&quot;,
      &quot;spring.datasource.username=[user]&quot;,
      &quot;spring.datasource.password=[password]&quot;,
      &quot;spring.jpa.database-platform = org.hibernate.dialect.PostgreSQLDialect&quot;,
      &quot;hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect&quot;,
      &quot;spring.jpa.database=postgresql&quot;})
  </code></pre>
  <p>But when I execute the tests with mvn clean install, in others test it returns me the error;</p>
  <pre><code>org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (the profiles &quot;test&quot; are currently active).
