这看起来很简单,但出于某种原因,我没有让它发挥作用。
我正在使用Selenium和Nunit。
我有一个名为'Registration_Test'的类,其中有一个名为'completeRegistrationForm()'的方法,如上所述。
我希望这种方法可以在多种不同的测试中使用。
这是我在第二次测试中所拥有的。
Registration_Test reg = new Registration_Test();
reg.completeRegistrationForm();
这很快乐地编译,但是当我在Nunit中运行它时,我得到以下结果:
SeleniumTests.Check_Links.Check_linksTest:
System.NullReferenceException : Object reference not set to an instance of an object.
它表示reg.completeRegistrationForm();线是罪魁祸首。
感谢您提供的任何帮助。
以下是我的两项测试:
注册-test.cs中
namespace SeleniumTests
{
[TestFixture]
public class Registration_Test
{
private ISelenium selenium;
private StringBuilder verificationErrors;
[SetUp]
public void SetupTest()
{
selenium = new DefaultSelenium("localhost", 4444, "*iexplore", "http://custom-creative-404-dropbox:8080/");
selenium.Start();
verificationErrors = new StringBuilder();
}
[TearDown]
public void TeardownTest()
{
try
{
selenium.Stop();
}
catch (Exception)
{
// Ignore errors if unable to close the browser
Console.Write("Unable to Stop Selenium and/or close the browser");
}
Assert.AreEqual("", verificationErrors.ToString());
}
[Test]
public void Registration()
{
completeRegistrationForm();
//back to home page.
selenium.Click("link=Home");
selenium.WaitForPageToLoad("30000");
}
public void completeRegistrationForm()
{
selenium.Open("/");
selenium.Click("link=Register");
selenium.WaitForPageToLoad("30000");
string uniqueVal = selenium.GetEval("\"AutomatedTest\" + (new Date().getDate()) + (new Date().getTime())");
//use moment instead.
selenium.Type("id=RegistrationForm_TxtName", uniqueVal);
selenium.Type("id=RegistrationForm_TxtUserName", uniqueVal + "@creative-404.com");
selenium.Type("id=RegistrationForm_TxtPassword", uniqueVal);
selenium.Type("id=RegistrationForm_TxtRePassword", uniqueVal);
selenium.Click("id=RegistrationForm_Button1");
selenium.WaitForPageToLoad("30000");
for (int second = 0; ; second++)
{
if (second >= 60) Assert.Fail("timeout");
try
{
if (selenium.IsTextPresent("Registration was successful!")) break;
}
catch (Exception)
{
Console.Write("Unable to find the Registration successful message. Something has gone wrong..");
}
Thread.Sleep(1000);
}
}
}
}
和Test-Links.cs(这个测试真的只是为了测试它)
namespace SeleniumTests
{
[TestFixture]
public class Check_Links
{
private ISelenium selenium;
private StringBuilder verificationErrors;
[SetUp]
public void SetupTest()
{
selenium = new DefaultSelenium("localhost", 4444, "*iexplore", "http://custom-creative-404-dropbox:8080/");
selenium.Start();
verificationErrors = new StringBuilder();
}
[TearDown]
public void TeardownTest()
{
try
{
selenium.Stop();
}
catch (Exception)
{
// Ignore errors if unable to close the browser
}
Assert.AreEqual("", verificationErrors.ToString());
}
[Test]
public void Check_linksTest()
{
Registration_Test reg = new Registration_Test();
reg.completeRegistrationForm();
selenium.Open("/home.aspx");
selenium.Click("link=Home");
selenium.WaitForPageToLoad("30000");
selenium.Click("link=Gallery");
selenium.WaitForPageToLoad("30000");
}
}
}

您可以附加到nUnit进程以调试失败的行http://frater.wordpress.com/2010/05/04/debugging-nunit-tests-under-visual-studio-2010/。
您可以将Visual Studio配置为在Debug> Exceptions中中断异常。在“Common Language Runtime Exceptions”旁边,选择“User-unhandled”。
