C# – How to load this file into an NUnit Test

.netc++nunittddtesting

I have the following IntegrationTest project structure …

enter image description here

If i wish to use that test data 126.txt in an NUnit Test, how do I load that plain txt file data?

NOTE: The file is -linked- and I'm using c# (as noted by the image).

cheers 🙂

Best Solution

You could specify in the properties of the file to be copied to the output folder and inside the unit test:

string text = File.ReadAllText(TestContext.CurrentContext.TestDirectory + "\\TestData\\126.txt");

As an alternative you could embed this file as a resource into the test assembly and then:

var assembly = Assembly.GetExecutingAssembly();
using (var stream = assembly.GetManifestResourceStream("ProjectName.Tests.IntegrationTests.TestData.126.txt"))
using (var reader = new StreamReader(stream))
{
    string text = reader.ReadToEnd();
}

C# – How to cast int to enum

From an int:

YourEnum foo = (YourEnum)yourInt;

From a string:

YourEnum foo = (YourEnum) Enum.Parse(typeof(YourEnum), yourString);

// The foo.ToString().Contains(",") check is necessary for enumerations marked with an [Flags] attribute
if (!Enum.IsDefined(typeof(YourEnum), foo) && !foo.ToString().Contains(","))
{
    throw new InvalidOperationException($"{yourString} is not an underlying value of the YourEnum enumeration.")
}

Update:

From number you can also

YourEnum foo = (YourEnum)Enum.ToObject(typeof(YourEnum) , yourInt);

Java – How to test a class that has private methods, fields or inner classes

Update:

Some 10 years later perhaps the best way to test a private method, or any inaccessible member, is via @Jailbreak from the Manifold framework.
@Jailbreak Foo foo = new Foo();
// Direct, *type-safe* access to *all* foo's members
foo.privateMethod(x, y, z);
foo.privateField = value;
This way your code remains type-safe and readable. No design compromises, no overexposing methods and fields for the sake of tests.

If you have somewhat of a legacy Java application, and you're not allowed to change the visibility of your methods, the best way to test private methods is to use reflection.

Internally we're using helpers to get/set private and private static variables as well as invoke private and private static methods. The following patterns will let you do pretty much anything related to the private methods and fields. Of course, you can't change private static final variables through reflection.

Method method = TargetClass.getDeclaredMethod(methodName, argClasses);
method.setAccessible(true);
return method.invoke(targetObject, argObjects);

And for fields:

Field field = TargetClass.getDeclaredField(fieldName);
field.setAccessible(true);
field.set(object, value);

Notes:
1. TargetClass.getDeclaredMethod(methodName, argClasses) lets you look into private methods. The same thing applies for getDeclaredField.
2. The setAccessible(true) is required to play around with privates.
