Good test suites need to be able to access direct the database. Below is how I do it with my test suite in Groovy in Gradle framework accessing a Oracle database:

(1) Connect the database in your code

class TestDB {

    static void main(String[] args) {

        def sql = Sql.newInstance('', 'username', 'password', 'oracle.jdbc.driver.OracleDriver')


(2) The special case with Oracle database is that is no ready to used library that we can download from Maven. I solve the problem by:

  • Download a copy of Oracle driver
  • Commit as part of the source code. I put under the Resource folder

file structure


  • In build.gradle, add the external Jar file as part of dependencies during compilation:
dependencies {
    compile 'org.codehaus.groovy:groovy-all:2.4.3'
    compile 'junit:junit:4.12'
    compile files('src/main/resources/ojdbc6.jar')
