Dropwizard integration test cannot find resource file

Question

Very new to dropwizard, I am trying to create an integration test "exactly" how they have it as an example:

https://dropwizard.github.io/dropwizard/manual/testing.html
public class LoginAcceptanceTest {

@ClassRule
public static final DropwizardAppRule<TestConfiguration> RULE =
        new DropwizardAppRule<TestConfiguration>(MyApp.class, ResourceHelpers.resourceFilePath("dev-config.yml"));

@Test
public void loginHandlerRedirectsAfterPost() {
    //Client client = new JerseyClientBuilder(RULE.getEnvironment()).build("test client");


}
}

so far having 2 issues: first of all when I run the test from intellij it fails with following exception:

Caused by: java.lang.IllegalArgumentException: resource dev-config.yml not found.

full stacktrace:

the dev-config.yml is definitely there:

ls -a 
.               .idea               build.sh            pom.xml
..              CKLA.iml            dev-config.yml          src
.git                README.md                       target
.gitignore          develop.sh           

Answer 1

Change the run directory of the program to be the root of the project (the one with the output of the ls -a command). Most likely currently you are running it from ./target directory.

Or if you want/need to run from .target change the command line options to refer the configuration file to: ../dev-config.yml

Edit: As @nightograph commented the exact thing to do in IntelliJ is to right click on the project folder and mark directory as "Resources Root"
