JsMockito

[Mark Nijhof]

Hi,

Is the build in stub functionality as rich as f.ex. JsMockito? I
really like syntax and such, also the ability to spy on other code,
without replacing it with an mock is interesting.

yup:

    obj.stub('someMethod').and_return({ some: 'object'})

will stub it for that spec only, then restore the old behavior. 

also:

    obj.should.receive('someMethod', 'once').with_args(an_instance_of(Array)).and_return('something')

etc

If I wanted to use JsMockito then I have to import it into JSpec, what
namespace should it import its methods into?

I will look more into the build in stub as well do.

Uhhmmm im not to sure how they support frameworks but you would probably

want to merge them into JSpec.defaultContext

I am trying mimick the spy stuff using stub and am running into a
small problem, I am trying not to replace the method but I just want
to be able to check that it is only called once. So I tried this:

jQuery.templateLoader.stub('makeAjaxCall')

but that makes the method do nothing anymore, I still want it to work,
so I tried the following:

jQuery.templateLoader.stub('makeAjaxCall').and_return(jQuery.templateLoader.makeAjaxCall)

But no avail.

Btw using jQuery shortcut $ doesn't work in the stub :)

$.templateLoader.stub('templateLoader') becomes this .templateLoader....

stubbing is way different. I call it a "proxy assertion", but you would do:

    jQuery.templateLoader.should.receive('makeAjaxCall').with_args('whatever').and_return('something')

both with_args() and and_return() are optional

also you can do:

    foo.should.receive('something', 'twice')

or

    foo.should.receive('something', 5)

'once' and 'twice' are accepted over numbers to make things more readable, but

they are the only ones mapped to ints

Ah very nice!

I didn't get the JsMockito to work, it worked halfway meaning that I
could call the spy and verify method, but the chain was broken after
that. So verify(function).times(2) told me that times was not a
function. They have some nice syntax, but yours works very well as
well.

Thanks for your time! Already written 105 tests TDD way and have found
lots of value in having them! I added a location.reload every 2500
miliseconds which works great. Will blog about it soon :-)

no problem!

You're not using the correct syntax for JsMockito. It should be
"verify(function, times(2))();", assuming that you're not wanting to
match any of the arguments passed to the function.

cheers,
chris
