In pseudocode the plan is as follows:. I implemented this plan using a C console application. I could just as easily have used another. NET Web application.
The test harness is surprisingly short and is shown in Figure 9. Let's go over it in detail so that you'll be able to modify it to meet your own particular needs. After adding a Web reference to the ProductsService service and adding a using statement for the System. Xml and System. Data namespaces, I start by declaring the four local string variables and one DateTime object that my test harness will use:.
The id, input, expected, and clue variables will hold information parsed from the XML test case input file. I get the start time so I can measure the total elapsed time of the test automation. It's often a good idea to time your test automation because an unusually long or short test run should be investigated. Timing Web service test automation is especially useful because there are generally several network connections involved and they are a potential source of trouble.
The object referenced by results is an XmlDocument from the System. Xml namespace. The next part of the test harness does most of the work:. I start by creating a second XmlDocument object, this one to hold the test case input. I use the XmlDocument. Load method to read my test case input file, whose path is provided to the test application is the first command-line argument, into memory.
Recall that each node looks like the following:. I iterate through the list of test case input nodes with a foreach loop. Because an XmlNodeList object is a collection, I could have also iterated with a for loop like so:. Inside the loop I send a test case input to the GetProducts Web method, capture the resulting DataSet object, use the expected value and clue to determine if the DataSet is correct, and write a pass or fail element into the test case result XmlDocument.
After all test case input nodes have been processed, I use the XmlDocument. Save method to write the in-memory results to an external file. I finish the test run by determining and displaying the total elapsed time for the text cases. Inside the foreach loop I begin by using the ChildNodes property to fetch the test case ID, test case input argument, an expected number of rows in the resulting DataSet, and a "clue" that will help me determine if the DataSet holds the correct data in its rows:.
This logic assumes that each test case input node has the exact same element and node structure so that even if I don't want to have a clue for a particular test case, I've still got to include one as an empty string. If you want, you can add logic to this part of test harness to first test whether the various attributes actually exist in order to handle variable-structure test case input.
Once I have the test case inputs, calling the Web service is easy:. I instantiate the ProductService Web service proxy just as I would any other local object that has a parameterless constructor. Of course, I had to add a Web Reference to the service into my test harness. NET parses that request and invokes the appropriate WebMethod with the specified arguments. With the results returned to the client, I write test case data into the XML test result element I created earlier:. Because XML is so flexible, there are many alternative formats I could have used.
The last few lines inside the test case input-controlled loop determine whether the test case passes or fails and adds that result to the test case result node:.

To apply AWS CodeDeploy, you specify the files to copy and the scripts to run on each instance throughout the deployment.
AWS CodeDeploy is a programming language and architecture agnostic so that you can use scripts for any custom deployment logic.
It will provide you a vast understanding of the services and features AWS has to offer. It has no prerequisites, not like some of the other certifications. So, an exam dedicated to developing the usage of AWS will surely help testers as well.
Will it be something that will save money? Thanks for this wonderful information. Your email address will not be published.
