Should unit tests be written for getter and setters?
...t later on, this will reinforce your assumptions.
A common bug is void setFoo( Object foo ){ foo = foo; } where it should be void setFoo( Object foo ){ this.foo = foo; }. (In the first case the foo that is being written to is the parameter not the foo field on the object).
If you are returning an a...
Check if full path given
...It also returns true for absolute paths.
System.IO.Path.IsPathRooted(@"c:\foo"); // true
System.IO.Path.IsPathRooted(@"\foo"); // true
System.IO.Path.IsPathRooted("foo"); // false
System.IO.Path.IsPathRooted(@"c:1\foo"); // surprisingly also true
System.IO.Path.GetFullPath(@"c:1\foo");// returns "...

> typeof "foo"
"string"
> typeof true
"boolean"
> typeof 42
"number"

So the statement can be written as
