- DP 101 in 60 simple slides
- www.AdvancedQTP.com
- What is DP?
- DP stands for
- Descriptive Programming
- But what IS DP?
- I t’s a cool way to work without QTP’s Object-Repository (OR)
- Why would I want to do that?
- Many reasons
- You have to
- Functions & Recovery scenarios work with different actions
- Different actions = Different ORs
- Do I know you? Can’t be sure…
- You have to
- Can’t record certain objects
- Auto-hide panels
- Objects with changing hierarchies
- Nested inner-objects, Sub menus
- Hold still, damnit! Even when you think you got it, all the properties turn out null
- Simplicity
- Why kill a fly with an atom bomb?
- No need to use the OR for every one-time click button in the application
- And,
- You can do VERY cool things with DP
- OK, bring it on
- First, we need to better understand the Object Repository
- What the OR is
- How does the OR work
- I thought DP is all about NOT using the OR…
- Well, yes, but under the hood, DP & the OR work the same way
- To understand the OR, is to understand DP
- What is the OR?
- A mysterious beast that records objects, in order to use them later
- What is to record an object?
- Write down how to identify it
- Who are you?
- Identification is done with
- properties and values
- Who are you?
- So, What IS the OR?
- Collections of properties & corresponding values
- Each collection represents an object
- No mysterious beast here
- OK, So what IS DP?
- DP is a way for specifying the properties & values without using the OR interface
- No mysterious beast here, either
- OK, I get it, there’s nothing more than properties and values
- Can we get on with it?
- How do I actually use DP?
- There are two ways
- 1
- Throw the properties and values straight into a command
- It’s the good old syntax you know, except the string between the () is not the OR name. It’s the property:=value identification string
- That’s kinda restrictive
- What if I want to use multiple identification properties?
- No problem:
- VBWindow(“height:=400”, “title:=New Document”).Maximize
- You can use as many properties as you like
- All fine and well, but what if I want to use regular expressions?
- No problem:
- VBWindow(“title:=.*Document.*”).Maximize
- ID strings are automatically interpreted as regular expressions
- 2
- Throw the properties & values into a description object, and throw IT into the command
- Here also, all the values are interpreted as regular expressions. To turn it off, use oDesc(“Property1”).RegularExpression = False
- Method 1 is faster, best used for one or two commands, tops
- When you want to execute multiple commands on an object, method 2 is a better choice by far
- (allows one-time definitions, multiple uses)
- You can use DP with OR
- VBWindow(“OR”).VBButton(“text:=OK”).Click
- Or (when oDesc is a description object):
- VBWindow(“OR”).VBButton(oDesc).Click
- But , you can only start from OR, and move to DP
- So this will not work:
- VBWindow(“title:=notgood”).VBButton(“clickme”).Click
- And that’s about it
- You can use each of the methods (or combine them), and you’ll be able to use objects that are not in the OR
- You said I could do really cool stuff with DP!
- Right you are
- We’ll cover some of the more popular tricks and tips
- These examples are only the tip of the iceberg. Play with them and see the true power of DP
- The power of the string
- DP is nothing more than simple strings
- We can do such interesting things with strings…
- The power of the string
- Say we got an app with 4 checkboxes, check0, …, check4
- We can set all of them with a nice simple loop:
- The power of the string
- Very complex identification tasks can be done via strings manipulation
- Try different variations for yourself
- Solving double objects
- When QTP finds two object which match the same description, it freezes
- This kinda sucks
- ?
- DP has a magic property: “index”, which allows us to tell the double objects apart
- Index is a zero-based counter
- All is well
- Getting objects collections
- This feature is so cool, deserves a title on its own
- THE coolest thing you can do with DP, is to get a collection of all the objects that math an identification
- I don’t know who you are, or how many are you, but I want to mark all of you! Regular DP won’t help - Don’t know how to identify each checkbox
- Object collections to the rescue!
- Step 1: define a description object
- Object collections to the rescue!
- Step 2: get all matching objects
- Object collections to the rescue!
- Step 3: Use the collection
- oChildren now holds a collection of all the checkboxes
- So the first checkbox is accessed by: oChildren(0)
- What can we do with it?
- Anything we want
- Example for common uses
- Mark all Checkboxes
- Mark all checkboxes with a certain property (even RO)
- The possibilities are endless
- Randomly input fields
- Input only mandatory fields
- Zero maintenance (new fields are added automatically, blind to UI changes)
- Select object which match complex identification criteria (write custom if filters)
- The list goes on and on…
- OK, this is indeed cool, but it only gets us the inner controls of a given window.
- Can we also get the application’s top level windows?
- Sure
- So, With DP we can work with no OR
- Sometimes we have to use it
- Other times it’s just more fun and useful
- DP also throws in a lot of extras that make it an inseparable part of good QTP automation
- Taste it, Experience it, Learn it, Use it, Love it
- It’s worth your while
- And that was DP in 60 slides
