如何使用字典在F＃中进行单元测试

Question

having problems unable to figure out why I can execute this code in f# unit testing

// testing the dictionary method 
   let callStatus = dict[
        "busy", "Monday";
        "quite", "Tuesday";
        "okay", "Friday";
        "ok", "Wednesday";
   ]

   Assert.AreEqual(("Wednesday",callStatus.['ok']))

the Error I am getting is Unmatched '[' which does not make sense as the same code in Console application works fine.

any support would be appreciated.

Answer 1

Not sure how but it appears by replacing the '' single quote marks with "" the error disappears

// testing the dictionary method 
let `` testing diction  `` () = 

    let callStatus = dict[
        "busy", "Monday";
        "quite", "Tuesday";
        "okay", "Friday";
        "ok", "Wednesday";
        ]

    Assert.AreEqual("Wednesday",callStatus.["ok"])

if someone can double check that I am correct, I would really appreciate this as I am a newbie.

Answer 2

Is this line correct:

Assert.AreEqual(("Wednesday",callStatus.['ok']))

Shouldn't it be

Assert.AreEqual("Wednesday",callStatus.["ok"])

UPDATE:

Added double quotes as well.
