is there a better way to test this class?
$begingroup$
Recently, I am learning unit test and try to use this skill in my project.
However, I have some question about how to test following code.
public class Class1
{
private Timer _timer = new Timer();
public Class1()
{
_timer.Interval = 1000;
_timer.Elapsed += _timer_Elapsed;
}
private void _timer_Elapsed(object sender, ElapsedEventArgs e)
{
//some works
}
public void start()
{
_timer.Start();
//some works
}
public void stop()
{
_timer.Stop();
//some works
}
}
I truly don't know how to test this class without breaking its encapsulation.
Should I expose '_timer_Elapsed' method? Evan if do so, next question comes to how to test method 'start' and 'stop'. Should I use stub object to substitute the Timer in order to test this class? if that, this class will be too complex because I need to make an interface and make a class which encapsulates Timer and implement the interface above.
public interface IEncal
{
double Interval { get; set; }
event ElapsedEventHandler Elapsed;
void Stop();
void Start();
}
public class MyClass : IEncal
{
Timer timer = new Timer();
public double Interval { get { return timer.Interval; } set { timer.Interval = value; } }
public event ElapsedEventHandler Elapsed
{
add { timer.Elapsed += value; }
remove { timer.Elapsed -= value; }
}
public void Start()
{
timer.Start();
}
public void Stop()
{
timer.Stop();
}
}
public class Class1
{
private IEncal _timer;
public Class1(IEncal timer)
{
_timer = timer;
_timer.Interval = 1000;
_timer.Elapsed += _timer_Elapsed;
}
public void _timer_Elapsed(object sender, ElapsedEventArgs e)
{
//some works
}
public void start()
{
_timer.Start();
//some works
}
public void stop()
{
_timer.Stop();
//some works
}
}
