how to tests when v.body is set

[esalman-sfdc]

I wonder if its timing issue as the callback passed to $A.createComponent() inside generateOrderForm() is async. May be try waiting (e.g. $T.waitFor(..)) for body length to change.

@esalman-sfdc like this?

$T.createComponent("c:pageContainer", {}, true)
.then(function(component){  
    $T.waitFor( function() {
        return component.get("v.body").length == 1;
    }, "component has loaded", 15000);

    $T.run(function () {
        expect(component.get("v.body").length).toBe(1);
    });
    done();
}).catch(function(e) {
    done.fail(e);
});

If so, doesn't work.

I don't think thats correct usage. See,

            $T.createComponent("c:pageContainer", {}, true)
            .then(function(component){ 
                return $T.waitFor(function(){
                    return component.get("v.body").length === 1;
                })
                expect(component.get("v.body").length).toBe(1);
                done();
            }).catch(function(e) {
                done.fail(e);
            });

waitFor returns a promise, so you'd need to chain it,

            $T.createComponent("c:pageContainer", {}, true)
            .then(function(component){ 
                return $T.waitFor(function(){
                    return component.get("v.body").length === 1;
                })
            }).then(function() {
                done();
            }).catch(function(e) {
                done.fail(e);
            });

this is for writing a jasmine test, correct?

[esalman-sfdc]

Pattern should work for both jasmine and mocha. If you are having trouble, feel free to link a gist/repo/unmanaged-package and I can have a closer look.
