How to do unit test on private method and event handler? and how to test on method that does not return anything (void)? not using assert?
Can someone provide example?

Thank you!

Hi,
If i want to test on event handler, how can i initialize the value to?
fyi,i'm using unit testing features in vsts2008

For example,
private void txtDate_KeyPress(object sender, KeyPressEventArgs e)
{
// Numbers, slash only
if ((e.KeyChar >= '0' && e.KeyChar <= '9') || (int) e.KeyChar == 8 || e.KeyChar == '/')
{
e.Handled = false;
}
else if ((int) e.KeyChar == 13)
{
txtMiles.Focus();
}
else
{
e.Handled = true;
}
}

(auto generated when i create unit testing)
[Test Method]
public void txtDate_KeyPressTest()
{
frmMileage_Accessor target = new frmMileage_Accessor(); // TODO: Initialize to an appropriate value
object sender = null; // TODO: Initialize to an appropriate value
KeyPressEventArgs e = null; // TODO: Initialize to an appropriate value
target.txtDate_KeyPress(sender, e);
}

User interface testing is a thorny subject to say the least. If you really want real in depth testing of your user interface then my advice to you is to head for model view controller pattern. That pattern's main goal is the separation of concerns between the three entities that give it its name.

More generally speaking you don't need a method to return some value in order to unit test it.

One possible way of asserting a result in your case would be to make a simple unit test that says if input key char is 13 then make sure that after the txtDate_KeyPress is called the txtMiles has focus.

then another unit test would asset that if the key char is between this and that, e.handled is true. or false.

the way you have it set up:

[Test Method]
public void txtDate_KeyPressTest()
{
frmMileage_Accessor target = new frmMileage_Accessor(); // TODO: Initialize to an appropriate value
object sender = null; // TODO: Initialize to an appropriate value
KeyPressEventArgs e = null; // TODO: Initialize to an appropriate value
target.txtDate_KeyPress(sender, e);
}

i would do something like this:

[Test Method]
public void txtDate_KeyPressTest_Enter()
{
//Arrange
frmMileage_Accessor target = new frmMileage_Accessor();
object sender = null; // Does not matter since you're not using this parameter
KeyPressEventArgs args = new KeyPressEventArgs((char)13);

//Act
target.txtDate_KeyPress(sender, args);

//Assert
Assert.IsTrue(target.txtMiles.Focused);

}

[Test Method]
public void txtDate_KeyPressTest_Number()
{
//Arrange
frmMileage_Accessor target = new frmMileage_Accessor();
object sender = null; // Does not matter since you're not using this parameter
KeyPressEventArgs args = new KeyPressEventArgs((char)50);

//Act
target.txtDate_KeyPress(sender, args);

//Assert
Assert.IsFalse(args.Handled);
}

...

etc.

also, consider using Char.IsDigit(e.KeyChar) instead of e.KeyChar >= '0' && e.KeyChar <= '9'. it's a bit more clear

Thanks for previous answer. How about the following?

private void btnSave_Click(object sender, EventArgs e)
{
// Save mileage data
int i;
sfdFiles.Filter = "Files (*.gas)|*.gas";
sfdFiles.DefaultExt = "gas";
sfdFiles.Title = "Save Mileage File";
if (sfdFiles.ShowDialog() == DialogResult.OK)
{
StreamWriter sw = new StreamWriter(sfdFiles.FileName);

this.Text = "Gas Mileage-" + sfdFiles.FileName;
sw.WriteLine(numValues);
for (i = 0; i < numValues; i++)
{
sw.WriteLine(dates[i]);
sw.WriteLine(odometer[i]);
sw.WriteLine(gallons[i]);
}
sw.Close();
}
}

[TestMethod()]
public void btnSave_ClickTest()
{
frmMileage_Accessor target = new frmMileage_Accessor(); // TODO: Initialize to an appropriate value
object sender = null; // TODO: Initialize to an appropriate value
EventArgs e = null; // TODO: Initialize to an appropriate value
target.btnSave_Click(sender, e);
//Assert.Inconclusive("A method that does not return a value cannot be verified.");
}

I should initialize value to EventArgs? I have problem to assign value to EventArgs. How is the correct answer look like?

you don't use that variable in your method body so i guess null would be as fine as anything else

How m i going to test this kind of function?

private void saverecord()
{
OleDbConnection savecon = new OleDbConnection(constring);
OleDbCommand savecom = new OleDbCommand("insert into Employee_Details values (?,?,?)", savecon);
OleDbParameter param;
param = savecom.Parameters.Add("@empcode", OleDbType.VarChar, 10);
param.Value = txtcode.Text;
param = savecom.Parameters.Add("@empname", OleDbType.VarChar, 25);
param.Value = txtname.Text;
param = savecom.Parameters.Add("@empjoin", OleDbType.Date);
param.Value = DateTime.Now.ToShortDateString();
savecon.Open();
int rows = savecom.ExecuteNonQuery();
MessageBox.Show(rows.ToString() + "rows affected");
btnref.PerformClick();
savecon.Close();
}

[TestMethod()]
public void saverecordTest()
{
Form1_Accessor target = new Form1_Accessor(); // TODO: Initialize to an appropriate value
target.saverecord();
//Assert.Inconclusive("A method that does not return a value cannot be verified.");
}

Hi,

I am trying to enable password recovery, with the following settings:

<membership defaultprovider="SqlMembershipProvider" userisonlinetimewindow="15">
      <providers>
        <clear />
        <add name="SqlMembershipProvider">
             type="System.Web.Security.SqlMembershipProvider" 
             connectionStringName="Gendac.Grintek.Abatis.DataAccess.Properties.Settings.PerimeterMainConnectionString" 
             applicationName="Abatis ClientUI" 
             enablePasswordRetrieval="true" 
             enablePasswordReset="true" 
             requiresQuestionAndAnswer="false" 
             requiresUniqueEmail="false" 
             passwordFormat="Encrypted" 
             minRequiredPasswordLength="3" 
             minRequiredNonalphanumericCharacters="0"/>
      </add></providers>
    </membership>

I know that I have to change the default machineKey, but I don't know how.

I think the machine key must be set in one of the files in C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG, but I don't know where and how.

Any help would be much appreciated.

This is my error:
You must specify a non-autogenerated machine key to store passwords in the encrypted format. Either specify a different passwordFormat, or change the machineKey configuration to use a non-autogenerated decryption key

Kind regards,
Higs

Well, you could do this using regular expressions, but personally I'd write a little function which iterates over the string and works it out (using StringBuilder) - that'd be quite a bit quicker.

easy...

string text = "abokf.okhj.jkoklk.";
string start = "ok";
string end = ".";
string replace = "D";
string answer = "abokD.okD.jkokD.";

console.WriteLine(answer);

of course you could optimise it...

console.WriteLine("abokD.okD.jkokD.");

...or perhaps you wanted something different Laugh | :laugh:

You sarcastic bunch!
This is a really difficult problem (if you have no experience and your IQ is smaller than your shoe size) so give the chap a break.
Just because it would take us less than a minute to complete (or two if we did it manually, rather than use built in members) doesn't mean we should take the piss out of really lazy students who want us to do thier homework for free.

So, the complete solution:

string s = "abokf.okhj.jkoklk.";
string startString = "ok";
string endString = ".";
string replacementString = "D";
while (ReplaceAllIncidencesOfDataDelimitedByTwoStringsWithAnotherStringForReallyLazyStudentsWithNoIdeaNoExperienceAndAnIQSmallerThanTheirShoeSize(ref s, startString, endString, replacementString))
   {
   }
Console.Writeline(s);

Obviously, you will need the method "ReplaceAllIncidencesOfDataDelimitedByTwoStringsWithAnotherStringForReallyLazyStudentsWithNoIdeaNoExperienceAndAnIQSmallerThanTheirShoeSize" and it is here, with all the others:
