[Junit-devel] How to Unit test Constructors in a Class

[Haricharan R. <har...@ya...>]

Hi All, =0A=0A  I am new to JUnit-devel list. and this is my first quetion.=
 =0A=0AI have a class with a constructor, the constructor takes a file name=
 as an agriment and assignes it to a instance variable of the type String. =
=0A=0AThis file name is later used in another method which when called will=
 open the file name as in the instance variable.=0A=0AThe class code looks =
like this=0A=0Aclass  ExClass =0A{=0A=0A  private String FILENAME =3D null;=
=0A=0A public ExClass(String FILENAME)=0A{=0A    this.FILENAME =3D FILENAME=
;=0A}=0A=0A// Other methods ....=0A}    =0A    =0A=0ACan any one please giv=
e suggestions to test this constructor.=0A=0A   What I have right now is a =
test case which trys to instantiate this class and verifies that an Object =
is created. =0AI can think of the following cases. =0A=0A     ExClass ExObj=
 =3D new ExClass("somefile.txt");=0A     assertNotNull(ExObj);=0A=0A       =
               [OR] =0A    boolean flah =3D false;=0A    try{=0A=0A        =
   ExClass ExObj =3D new ExClass("somefile.txt");=0A       }=0A    catch (E=
xception e) { flag =3D true; }=0A    assertFalse(flag);=0A=0Athanks=0AHari=
