Assembly.GetEntryAssembly() in NUnit

I am using NUnit to test one functionality where I need to load XML file to object. The XML file is in location of the Console Application.

I have Following method where configuration will be read :

public string GetConfiguration(TempFlexProcessor processor)
{
    var exePath = Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location);
    var configPath = Path.Combine(Path.GetFullPath(exePath), "configuration");
    var configFile = string.Format(@"{0}.xml", processor.GetType().Name);
}

Now in my NUnit Test I have test method where I test GetConfiguration :

[Test]
    public void TempFlexProcessorExecuteTest()
    {
        #region Given


        #endregion

        #region When

        var tempFlexProcessor = new TempFlexProcessor();
        var actual = tempFlexProcessor.GetConfiguration(tempFlexProcessor);

        #endregion

        Assert.AreEqual("path of the file", actual);
    }

But System.Reflection.Assembly.GetEntryAssembly() is null, please help.

I used AppDomain.CurrentDomain.BaseDirectory instead of System.Reflection.Assembly.GetEntryAssembly().Location

I suspect the problem is that NUnit is running your tests in a different AppDomain, but without using ExecuteAssembly. From the documentation for Assembly.GetEntryAssembly:

Gets the process executable in the default application domain. In other application domains, this is the first executable that was executed by AppDomain.ExecuteAssembly.

It's not clear which assembly you really want to get - even if this did return something "appropriate" for NUnit, that's likely to be the NUnit executable, which would be well away from any configuration directories you happen to have.

Basically, I think that you should at least provide an alternative way of specifying the configuration directory - and you might want to reconsider whether using GetEntryAssembly is a good idea anyway. (Aside from anything else, it's slightly odd that you're calling GetConfiguration on a processor and passing in another processor... that may be suitable for your design, but it's at least somewhat unusual, given that in your test case you're passing in a reference to the same object.)
