NullReferenceException when running tests

[vtortola]

Hi,

Everytime I try to run a test, I get a null reference exception:

TestApplication.UiTests.CalculatorFeatureFeature.AddTwoNumbers:
System.NullReferenceException : Object reference not set to an instance of an object.

This is happening even in the examples provided in GitHub. What I did:

• downloaded the code from GitHub
• opened the solution TestApplication.sln.
• built it
• opened the nUnit runner
• opened the TestApplication.UiTests.dll library
• run the tests
• then I get:

TestApplication.UiTests.CalculatorFeatureFeature.AddTwoNumbers:
System.NullReferenceException : Object reference not set to an instance of an object.
TestApplication.UiTests.CalculatorFeatureFeature.AddTwoNumbers:
System.NullReferenceException : Object reference not set to an instance of an object.
TestApplication.UiTests.CalculatorFeatureFeature.AddTwoNumbers:
System.NullReferenceException : Object reference not set to an instance of an object.
TestApplication.UiTests.CalculatorFeatureFeature.AddTwoNumbers:
System.NullReferenceException : Object reference not set to an instance of an object.
TestApplication.UiTests.CalculatorFeatureFeature.BasepageIsCalculator:
System.NullReferenceException : Object reference not set to an instance of an object.
TestApplication.UiTests.CalculatorFeatureFeature.BasepageIsCalculator:
System.NullReferenceException : Object reference not set to an instance of an object.
TestApplication.UiTests.CalculatorFeatureFeature.BasepageIsCalculator:
System.NullReferenceException : Object reference not set to an instance of an object.

The exception details shows:

at NUnit.Core.Extensibility.ParameterSet.FromDataSource(Object source)
at NUnit.Core.Builders.TestCaseParameterProvider.GetTestCasesFor(MethodInfo method)

I am using:

• VS 2013 Express
• . NET 4.5
• WebDriver 2.35.0.0
• SpecFlow 1.9.0.77

I have tried in .NET 4.0 and Visual Studio 2010 with libraries compiled for that version, and got the same issue.

Any idea what could be the problem?

What version of nunit are you using?

Right on the spot. Apparently there is two nUnit versions installed, one for 2.0 and other for the rest.

I works great, nice job.
