how can I force C++ macro substitution at the time I choose in this case?

should help you out The C preprocessor does brute-force text replacement; it has no sense of scopes and cannot be used to create a closure in this manner.

Force JUnit to run one test case at a time

Force JUnit to run one test case at a time

With these it helps Your problem is not that JUnit runs all the tests at once, you problem is that you don't see why a test fails. Solutions:
Add more asserts to the tests to make sure that every variable actually contains what you think Download an IDE from the Internet and use the built-in debugger to look at the various variables Dump the state of your objects just before the point where the test fails. Use the "message" part of the asserts to output more information why it fails (see below) Disable all but a handful of tests (in JUnit 3: replace all strings "void test" with "void dtest" in your source; in JUnit 4: Replace "@Test" with "//D@TEST").
code :
assertEquals(list.toString(), 5, list.size());

I wish this help you Well, the simplest, easiest workaround that solves this particular issue is:
code :
// It was this...
// #define PERIPHERAL_TIMER    TCC0

// And is now this
#define PERIPHERAL_TIMER_SUFFIX    C0
// Conceptually what I want - modified, but be sure to use 
// indirect substitution as required.
#define EVENT_SOURCE(timer)    EVSYS_CHMUX_TC ## timer ## _OVF_gc
// Don't forget, you'll need to use indirect substitution
#define PERIPHERAL_TIMER    TC ## PERIPHERAL_TIMER_SUFFIX

// Registers can still be access as:
value = PERIPHERAL_TIMER.CCA;

Hope that helps Yes, macros are expanded “from the outside in”. After expanding define-simple-class, the subform (autowire java.util.List foo) does not exist anymore.
If you want this kind of behaviour modification, you need to define your own define-not-so-simple-class macro, which might expand to a define-simple-class form.

Any of those help As others have said, you need to call the removeSpecial.
That said, I would rewrite removeSpecial to specify characters you want to keep, as there are many more special characters than what you have listed in removeSpecial
code :
Function removeSpecial(sInput As String) As String
    Dim sKeepChars As String
    Dim sClean As String
    Dim c As String
    Dim i As Long, j As Long
    Const ReplaceFrom As String = "AE"
    Const ReplaceWith As String = "ÀÊ"

    sKeepChars = "[-&A-Z" & ReplaceWith & "]"
    For i = 1 To Len(sInput)
        c = Mid$(sInput, i, 1)
        If c Like sKeepChars Then
            j = InStr(ReplaceFrom, c)
            If j Then
                c = Mid$(ReplaceWith, j, 1)
            End If
            sClean = sClean & c
        End If
    Next
    removeSpecial = sClean
End Function


Private Sub FINALIZEBTN_Click()
    Dim response As VbMsgBoxResult
    response = MsgBox("Have you completed the form in full?", vbYesNo)
    If response = vbYes Then
        MsgBox "Do not forget to save and submit this form"
    ElseIf response = vbNo Then
        MsgBox "Please review and complete the form in full"
        Exit Sub
    End If

    Application.ScreenUpdating = False
    Dim cell As Range
    Dim rng As Range
    With ActiveSheet
        On Error Resume Next
            Set rng = .Cells.SpecialCells(xlCellTypeConstants)
        On Error GoTo 0
        If Not rng Is Nothing Then
            For Each cell In rng
                cell = removeSpecial(UCase(cell))
            Next cell
        End If
    End With
    Application.ScreenUpdating = True
End Sub

it fixes the issue That's something that the preprocessor simply cannot do. But if the operation can (theoretically) be done at preprocessor time, then it can also be done at compile time, and the optimizer will take care of such things.
So a code snippet like this:
code :
#define add(x,y) (x+y)
int x=add(4,5);
int x=(4+5);
#if 1 + 1 == 42
...
#endif
