Validation of WebTest

thank you for the quick answer.
I am a beginner in VST2005 TE for Testers and it's the task of my thesis to create some automatic tests.

Well I will show you the problem:
There is a "website1" with content, in my example there are some orders. It looks like this one:

Order	Ordernumber	Orderdate	Order start
build cars	bc123	06-20-2007	no
build houses	bh789	06-25-2007	yes
build streets	bs234	07-01-2007	no

Each order has got an own page called "website2" with more details like this one:

Order	Builder	address	Ordernumber	orderowner	Orderdate	Orderstart
build houses	Mr. Smith	Street 1	bh789	J.K.	06-20-2007	yes

I want to validate, if the facts for the order "bh789" of website1 are the same on "website" for order "bh789". I want to validate the facts (like date) and the color of the last cell (like yellow).

So I thought I could extract the data of website1 and then I could extract the data of "website" and after this a can validate the both to check if there are some mistakes?

Please tell me if this is the wrong way. How would you do this test for this example? The problem is there is not such a good help and here in germany you can't buy any books for automatic testing with VS2005 TE. I can't find good examples on the web. There is also nobody who can be called up to help in some facts so the forum is my last hope.

Thank you very much.
Best regards

that's exactly this I want to do, I used a longer "startswith"-string for the order. Thank you very much - it works great!

But in this situation I have got an other question:

Is it possible to add or subtract some facts?
For example:

Order	Ordernumber	Orderdate	Order start	Amount	additional Amount
build cars	bc123	06-20-2007	no	100	37

I want to check if "amount" + "additional Amount" = 137
I can extract the two cells - the extracted values would be 100 and 37. But how can I add these two values and check if they are an amount of 137?

Best regards,

Andreas

Here is a brief walk through of how you might do this using both the built-in extraction rules and a custom validation rule.

Let's assume you have a web test with two requests. The first request uses two extractions rules to extract two integer values from its response. Also, let's assume the response to the second request has the value that should represent the sum of the two integers extracted in the first response.

In my example, the first response contains the following unique character sequence that I want to extract (without the quotes)...

">P1=10<"

">P2=20<"

And the second response contains the following unique character sequence that i want to validate (without the quotes)...

">P3=30<"

Request1 contains the following two extraction rules...

ExtractText

ContextParameterName=P1

StartsWith=>P1=

EndsWith=<

ExtractText

ContextParameterName=P2

StartsWith=>P2=

EndsWith=<

Request2 constains the following validation rule...

SumValidationRule (a custom rule shown below)

StartsWith=>P3=

EndsWith=<

Arg1={{P1}}

Arg2={{P2}}

Note that the notation for Arg1 and Arg2 in the validation rule indicates that we are passing in the values from the test context which were extracted by the rules for request1.

Here's the code for the sample custom validation rule...

publicclassSumValidationRule : ValidationRule

privatestring m_arg1;

privatestring m_arg2;

privatestring m_startsWith;

privatestring m_endsWith;

publicstring Arg1 { set { m_arg1 = value; } }

publicstring Arg2 { set { m_arg2 = value; } }

publicstring StartsWith { set { m_startsWith = value; } }

publicstring EndsWith { set { m_endsWith = value; } }

publicoverridevoid Validate(object sender, ValidationEventArgs e)

{

try

string body = e.Response.BodyString;

int startIndex = body.IndexOf(m_startsWith);

if (startIndex != -1)

{

int endIndex = body.IndexOf(m_endsWith, startIndex + m_startsWith.Length);

if (endIndex != -1)

{

string extractedString = body.Substring(startIndex + m_startsWith.Length, endIndex - (startIndex + m_startsWith.Length));

int extractedValue = Int32.Parse(extractedString);

int arg1 = Int32.Parse(m_arg1);

int arg2 = Int32.Parse(m_arg2);

e.IsValid = (arg1 + arg2 == extractedValue);

}

}

}

catch

e.IsValid = false;

}

}

}

Here's the steps I followed to create the sample custom validation rule...

1. Create a new class in the project containing the web test (it could have been created in a different project as well, but a project reference would have to be added to the project containing the web test in this case).
2. Name the class SumValidationRule.cs
3. Extend the class from ValidationRule by typing ": ValidationRule" at the end of the class definition.
4. Add the using statement for Microsoft.VisualStudio.TestTools.WebTesting (note, the little red underline that appears under the text ValidationRule when you type it, hover it, then choose to automatically insert the using... or just type it in manually).
5. Make the class public. (type "public" in front of the class definition). Note, if you forget to make the class public, it will not show up in the validation rule selection dialog in the web test editor.
6. Add the properties that I want to have supplied to my validation rule (Arg1, Arg2, StartsWith, EndsWith).
7. Override the "Validate" method with the code that I want executed.
8. Add the code shown above.
   1. Get access to the response body
   2. Find the index of startWith
   3. Find the index of endsWith
   4. Extract the string between startWith and EndsWith
   5. Convert the extracted value and arguments to integers
   6. test the sum
   7. IsValid is true if the validation rule passes, false otherwise.
   8. You could also use e.Message to indicate reasons for failure.

To test this, I placed a breakpoint on the first line of the Validate method (F9), and then chose "Debug Test" from the toolbar in the web test editor to start running the web test under control of the debugger. When the web test reached my custom validation rule, VS broke into the debugger. I then single stepped through the code to verify it was working correctly. Pressed F5 to resume execution, and the test passed.

Hope this helps.
