    I was toldo the other day that in ten years there will be no testers because developers will do all the testing.

    I’ve seen how it works out in practice: there’s not enough time for testing and for developing, too, developers are going to burn and the product is going to be shit done and shit tested. Maybe it works if your company is willing to spend extra for less results by someone doing all the stuff less efficient than what they could, but that’s a rare occurrence.












  • I mostly come to prefer composition, this approach apparently even has a wiki page. But that’s in part because I use Rust that forbids inheritance, and don’t have such bullshit (from delegation wiki page):

    class A {
        void foo() {
            // "this" also known under the names "current", "me" and "self" in other languages
            this.bar();
        }
    
        void bar() {
            print("a.bar");
        }
    }
    
    class B {
        private delegate A a; // delegation link
    
        public B(A a) {
            this.a = a;
        }
    
        void foo() {
            a.foo(); // call foo() on the a-instance
        }
    
        void bar() {
            print("b.bar");
        }
    }
    
    a = new A();
    b = new B(a); // establish delegation between two objects
    

    Calling b.foo() will result in b.bar being printed, since this refers to the original receiver object, b, within the context of a. The resulting ambiguity of this is referred to as object schizophrenia

    Translating the implicit this into an explicit parameter, the call (in B, with a a delegate) a.foo() translates to A.foo(b), using the type of a for method resolution, but the delegating object b for the this argument.

    Why would one substitute b as this when called from b.a is beyond me, seriously.
