Question

I’m using Groovy 1.8.6 and Grails 2.1.1

I have a interface

public interface Searchable{
    Long docVersion()
}

Implemented by a object

class Book implements Searchable {
    Long docVersion() {
        System.currentTimeMillis() / 1000L
    }

    String otherMethod() {
        "toto"
    }
}

And a test

@Mock([Book])
class SomeBookTester {
    @Before
    void setup() {
        Book.metaclass.docVersion = {-> 12345}
        Book.metaclass.otherMethod = {-> "xyz"}
    }

    @Test
    void test1() {
        assert 12345 == new Book().docVersion()
    }

    @Test
    void test2() {
        assert "xyz" == new Book().otherMethod()
    }
}

The first test always fail because the methode replacement dosen’t work. How could I fix this? What’s the probleme?

Answer 1

This works for me

I change the class like that:

class Book implements Searchable {
    Long docVersion() {
        currentTime()
    }

    Long currentTime() {
        System.currentTimeMillis() / 1000L
    }

    String otherMethod() {
        "toto"
    }
}

And in the test, I replace the currentTime method

@Mock([Book])
class SomeBookTester {
    @Before
    void setup() {
        Book.metaclass.currentTime= {-> 12345}
        Book.metaclass.otherMethod = {-> "xyz"}
    }

    @Test
    void test1() {
        assert 12345 == new Book().docVersion()
    }

    @Test
    void test2() {
        assert "xyz" == new Book().otherMethod()
    }
}

Tests passes
