it fixes the issue take BufferedReader out of your method, e.g. change signature of your method to
code :
 public static float average(BufferedReader reader) throws IOException {}

Need Help Writing Unit Test that on Method that requires HttpContext.Current.User

With these it helps It looks like you are trying to test the MemberQueries.IsEditModeAvailable method. You have 2 cases to cover here. The Site Administrators case and the case where there's a currently logged user whose id matches the one passed as argument. And since the MemberQueries class relies purely on interfaces you could mock everything:
code :
[TestMethod]
public void EditMode_Must_Be_Available_For_Site_Administrators()
{
    // arrange
    var unitOfWork = new Mock<IUnitOfWork>();
    var currentUser = new Mock<IPrincipal>();
    currentUser.Setup(x => x.IsInRole("Site Administrator")).Returns(true);
    var memberServices = new Mock<IMemberServices>();
    var memberQueries = new MemberQueries(unitOfWork.Object, memberServices.Object, currentUser.Object);

    // act
    var actual = memberQueries.IsEditModeAvailable(1);

    // assert
    Assert.IsTrue(actual);
}

[TestMethod]
public void EditMode_Must_Be_Available_For_Logged_In_Users_If_His_Id_Matches()
{
    // arrange
    var unitOfWork = new Mock<IUnitOfWork>();
    var currentUser = new Mock<IPrincipal>();
    var identity = new Mock<IIdentity>();
    identity.Setup(x => x.Name).Returns("john.doe@gmail.com");
    currentUser.Setup(x => x.Identity).Returns(identity.Object);
    currentUser.Setup(x => x.IsInRole("Site Administrator")).Returns(false);
    var memberServices = new Mock<IMemberServices>();
    var member = new Member
    {
        Id = 1
    };
    memberServices.Setup(x => x.FindByEmail("john.doe@gmail.com")).Returns(member);
    var memberQueries = new MemberQueries(unitOfWork.Object, memberServices.Object, currentUser.Object);

    // act
    var actual = memberQueries.IsEditModeAvailable(1);

    // assert
    Assert.IsTrue(actual);
}
[TestMethod]
public void EditMode_Should_Not_Be_Available_For_Logged_In_Users_If_His_Id_Doesnt_Match()
{
    // arrange
    var unitOfWork = new Mock<IUnitOfWork>();
    var currentUser = new Mock<IPrincipal>();
    var identity = new Mock<IIdentity>();
    identity.Setup(x => x.Name).Returns("john.doe@gmail.com");
    currentUser.Setup(x => x.Identity).Returns(identity.Object);
    currentUser.Setup(x => x.IsInRole("Site Administrator")).Returns(false);
    var memberServices = new Mock<IMemberServices>();
    var member = new Member
    {
        Id = 2
    };
    memberServices.Setup(x => x.FindByEmail("john.doe@gmail.com")).Returns(member);
    var memberQueries = new MemberQueries(unitOfWork.Object, memberServices.Object, currentUser.Object);

    // act
    var actual = memberQueries.IsEditModeAvailable(1);

    // assert
    Assert.IsFalse(actual);
}

Using JUnit to test a main method that requires simulation of keyboard input with an input stream?

Does that help Let's suppose I have a program with a main method that uses the java.util.Scanner class to receive user input. , You can redirect System.out, System.in, and System.err like this:
code :
System.setOut(new PrintStream(new FileOutputStream("output")));

System.setErr(new PrintStream(new FileOutputStream("error")));

System.setIn(new FileInputStream("input"));

I wish this helpful for you I had to change it to an Async test. to @peeskillet ! Also I had to change "key": "escape" to "code": "ESCAPE"
code :
it('should trigger escape event', async(() => {
        component.formProps.ausgeklappt = true;
        fixture.detectChanges();
        let spy = spyOn(component, "closeForm");
        const event = new KeyboardEvent("keypress",{
          "code": "ESCAPE",
        });
        fixture.nativeElement.dispatchEvent(event);

        component.keyboardInput(event);
        expect(spy).toHaveBeenCalled();
      }));

To fix the issue you can do You can also use Microsoft Coded UI Tests. Disadvantage is that you need at least Visual Studio (2012) Premium. Works fine in your projects.

To fix the issue you can do In this kind of situations I would reccomend you to write UI Tests (use Espresso for example with Espresso Test Recording: https://developer.android.com/studio/test/espresso-test-recorder.html).
