loops in vba code example
Example 1: vba for loop
For i = 1 to 100
'Code here is executed 100 times.
Next
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
'Notes: The For loop is terminated with the 'Next' keyword. There is no need
' to include the counter variable as part of Next, for example: "Next i".
'
' However, there is nothing wrong with doing so and some programmers feel
' including the counter variable improves readability. I don't.
'
' The speed of the loop is not affected by this decision. However,
' the speed of the loop IS affected by the choice of the type of variable
' used as the counter. A Long (&) is the quickest variable type
' to choose for the counter variable.
'
' In the above example, the range to iterate over is hard coded with
' constant values, 1 to 100. Variables or even expressions can be
' used intead of constant values. This adds significant dynamicism
' to the For loop.
'
' BUT, the variables or expressions used in the For loop range are
' evaluated only ONCE (before the loop starts). This makes
' the execution of the For loop efficient.
'
' However, this also means that changing the value of these variables
' DURING the For loop execution does NOT alter the original range
' that the For loop iterates over:
a = 1
b = 100
For i = a to b
b = 5
'This For loop still iterates 100 times
Next
' A For loop can be exited EARLY by use of the 'Exit For' statement:
For i = a to b
If str = "abc" Then Exit For
Next
' In the above sample code, if the variable 'str' ever equals
' "abc", then the For loop will instantly terminate, even if
' the range in not fully iterated.
'
' When 'Exit For' executes, execution resumes on the very next
' line of code following the 'Next' statement. If the For loop
' was nested inside of another loop, the nearest outer loop now
' continues execution. If the For loop is within a 'Function' or
' a 'Sub', there are two other options to exit the For loop early.
' Both 'Exit Function' and 'Exit Sub' will immediately terminate
' the For loop... but they will also immediately end the execution
' of, and immediately exit from, the current procedure.
' By default the For loop iterates in steps of positive ONE. This
' can be adjusted with the optional 'Step' keyword:
For i = 1000 to 0 Step -10
'This loop iterates from 1000 to 0 (reverse iteration) by 10s.
'So i will equal 1000, 990, 980, 970... 0.
Next
' Step values can be positive or negative. VBA's compiler will not prevent
' you from using a ZERO value for the Step value, but don't do this unless
' you really want to. It creates an INFINITE loop with the value of the
' counter variable ALWAYS equal to the start value.
'
' Step values can be variables or expressions that evaluate to any numeric
' type. But be careful about floating point values. Floating point
' Step values may work... even for a long time... and then fail
' unpredictably (which can make debugging extremely difficult). Integer
' Step values are safe, always. And again, the Long (&) integer will
' allow the For loop to iterate quickest.
'
' If the start value (constant, variable, expression) of the iteration
' range is greater than the end value (constant, variable, expression)
' then the loop is SKIPPED entirely. This behavior occurs when the
' Step value is POSITIVE. The reverse is true when the Step value
' is NEGATIVE.

' ================================================================
' METHOD: FUNDAMENTAL
'EXAMPLE
Dim iTotalPrints As Integer
iTotalPrints = 5
For iCount = 1 To iTotalPrints
MsgBox Prompt:=iCount, Title:="Method: Fundamental"
Next
'SYNTAX
' For <your-variable-to-be-used> = <first-number> To <last-number>
' 'Code that uses <your-variable-to-be-used>
' Next
' ================================================================
' METHOD: WITHIN AN ARRAY
'EXAMPLE
Dim sTextList(4) As String 'Note: doesn't have to be of "String" data-type
sTextList(0) = "aaa"
sTextList(1) = "bbb"
sTextList(2) = "ccc"
sTextList(3) = "ddd"
sTextList(4) = "eee"
For Each sSeparateText In sTextList
MsgBox Prompt:=sSeparateText, Title:="Method: Within an Array"

What do you do until the code arrives in your
environment?
Our framework is generated based on BDD using Page Object Model
and we are also using Cucumber testing tool which supports BDD.
Until the code arrives my environment, just by analyzing the user
stories and acceptance criteria I can prepare the feature file with the
scenario, step definition class with the methods, and page class with
the webelements. All I need is the code and location of the
webelements. As soon as I receive the codes, I locate the
webelements and update my work. That is, it.
Day 5 Grooming Meeting takes place whole team attends and we go
into details of the product backlog items for the upcoming sprint,
break epics into user stories and point them.
During the Grooming, we also point the UPCOMING SPRINT’s user
stories based on their complexities.
· - Team, SM, and PO get together to ensure work items are
relevant and useful
· - Ask questions to P.O of user stories
· - Redefine acceptance criteria
· - Writing new stories
· - Breaking epics into user stories
- Understand the story to give proper estimation/to prevent
under/over estimate
