Hidden Features of F# -

-

this unabashed attempt of similar c# question.

so favorite f# hidden (or not) features?

most of features i've used far aren't hidden have been quite refreshing. how trivial overload operators compared c# or vb.net.

and async<t> has helped me shave off real ugly code.

i'm quite new language still it'd great learn other features being used in wild.

user defined numeric literals can defined providing module name starts numericliteral , defines methods (fromzero, fromone, etc.).

in particular, can use provide more readable syntax calling languageprimitives.genericzero , languageprimitives.genericone:

module numericliteralg = begin   let inline fromzero() = languageprimitives.genericzero   let inline fromone() = languageprimitives.genericone end  let inline genericfactorial n =   let rec fact n = if (n = 0g) 1g else n * (fact (n - 1g))   fact n  let flt = genericfactorial 30. let bigi = genericfactorial 30i

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
