Run Test Play! Framework - DataSource user is null

Question

Hello I am trying run a simple test in a web app using Play! Framework, but I got a error:

[info] RouteTest
[error] Test RouteTest.testRouteActivityIndex failed: DataSource user is null?

The code of test is:

    @Test
public void testRouteActivityIndex(){
    Result result = routeAndCall(fakeRequest(GET, "/activities"));
    Assert.assertNotNull(result);
}

I tried researching the error, but did not find anything very useful for this case, even the site's play!. someone has gone through this?

Answer 1

Your /activities action probably make some calls to the DB.

So you should make your test in a running fake application as explained in the "Running in a fake application" section of this documentation: http://www.playframework.org/documentation/2.0.3/JavaTest

And don't forget to import the static Helper:

import static play.test.Helpers.*;
