Question

When executing ‘play test’, is there a way to pass in system properties to be used at test cases?

String testDB = System.getProperties().getProperty("testDB");

Map<String, String> conf = new HashMap<String, String>();
if (testDB.equals("localdb")) {
    conf.put("db.default.driver", "org.postgresql.Driver");
    conf.put("db.default.url", "postgres://postgres:postgres@localhost/db");
} else if (testDB.equals("memorydb")) {
    conf.put("db.default.driver", "org.h2.Driver");
    conf.put("db.default.url", "jdbc:h2:mem:play-test");
} else {
    conf.put("db.default.driver", "org.postgresql.Driver");
    conf.put("db.default.url", "postgres://postgres:postgres@localhost/db");
}

running(fakeApplication(conf), new Runnable() {
    public void run() {
    int preRowCount = Info.find.findRowCount();
        Info info = new Info("key");
        info.save();
        assertThat(Info.find.findRowCount()).isEqualTo(preRowCount+1);
        info.delete();
    }
});

I tried ‘play test -DtestDB=localdb’, but got null value in testDB.

Answer 1

1.2.4

Try play run -DtestDB=localdb --%test

I found that at the bottom of http://www.playframework.org/documentation/1.2.4/ids where it states that play test is equivalent to play run --%test.

2.0

Try play -DtestDB=localdb test

The system property needs to be before the command.
