how many test cases in this case ?

[Vikrama Sanjeeva]

Hi all,

Please advise how many test should be there for below method ? And also all test cases should be check in one test method or separate ?

    String CarNames getCarNames(Car car)

This method is expecting:
(i) car should not be null
(ii) car should not be empty
(iii) car should have at least one character
(iv) car may contain comma separated characters

Bye,
Viki.

Vikrama,
I'm not sure what you mean by a car containing characters.

Another criteria for tests may be an empty list returns vs matching results returned. Each test should definitely be in a separate test method to keep them independent. You want all the tests to run so you know which pass.

Hi Jeanne,

Car containing characters is just used for example. This can be string as well. But let's keep it to characters to avoid any confusion.

In my opinion, we should have "at-least" below test cases.

1: car should not be null and empty
2: car should have "at-least" once character
3: Only comma is considered as delimiter
3: return type CarNames should not be null

and then

4: car should be compared against true car value (s)
5: CarNames value (s) should be compared against true CarNames.

First ,

String CarNames getCarNames(Car car)

May I know what is that ? a method signature ? with two return type String class an CarNames class ?

Second,
What you want to test? Are you testing the Car class? or are you testing your utility Class with the getCarNames method?
