Beginners' questions in VS

Question

1.I wrote code, and created a test project on it. I made a "reference" between them. And yet when I run the test the system does nothing. The test explorer shows that there are 3 tests that have not been run but does not execute them. Do you have an idea why?

2. Similar to 1. in another project, I wrote a test code that uses a class from the program code itself. There is a build error because it does not recognize the class. What should be done?
3. Is IntelliTest a component that exists in VS? Do I need to download/install it separately? If so, in what way?

We are talking about vs2022 enterprise, and the code is in C#.

Thanks

Thanks!

Here is the code itself:

---

using System;

namespace UtilityLibraries

{

public static class StringLibrary

{

public static bool StartsWithUpper(this string s)

{

if (String.IsNullOrWhiteSpace(s))

return false;

return Char.IsUpper(s[0]);

}

public static bool StartsWithLower(this string s)

{

if (String.IsNullOrWhiteSpace(s))

return false;

return Char.IsLower(s[0]);

}

public static bool HasEmbeddedSpaces(this string s)

{

foreach (var ch in s.Trim())

{

if (ch == ' ')

return true;

}

return false;

}

}

}

And the testing code

---

using System;

using Microsoft.VisualStudio.TestTools.UnitTesting;

using UtilityLibraries;

namespace StringLibraryTest

{

[TestClass]

public class UnitTest1

{

[TestMethod]

public void TestStartsWithUpper()

{

// Tests that we expect to return true.

string[] words = { "Alphabet", "Zebra", "ABC", "Αθήνα", "Москва" };

foreach (var word in words)

{

bool result = word.StartsWithUpper();

Assert.IsTrue(result,

$"Expected for '{word}': true; Actual: {result}");

}

}

[TestMethod]

public void TestDoesNotStartWithUpper()

{

// Tests that we expect to return false.

string[] words = { "alphabet", "zebra", "abc", "αυτοκινητοβιομηχανία",

"государство",

"1234", ".", ";", " " };

foreach (var word in words)

{

bool result = word.StartsWithUpper();

Assert.IsFalse(result,

$"Expected for '{word}': false; Actual: {result}");

}

}

[TestMethod]

public void DirectCallWithNullOrEmpty()

{

// Tests that we expect to return false.

string[] words = { String.Empty, null };

foreach (var word in words)

{

bool result = StringLibrary.StartsWithUpper(word);

Assert.IsFalse(result,

$"Expected for '{(word == null ? "<null>" : word)}': " +

$"false; Actual: {result}");

}

}

}

}
