In my last post, we have seen that what is mock service and
how to use it. In the previous blog (http://lgsofttest.blogspot.no/2014/07/web-service-testing-using-mock-service.html)
I have described about static mock response, meaning only one response for different
inputs in request. Now in this post I am going to describe about dynamic mock
response, which gives different response for each different input in request.
Let us start, Create project and test suite, and add Request
to Mock Service, as described in my previous blog (http://lgsofttest.blogspot.no/2014/07/web-service-testing-using-mock-service.html).
The project structure looks like below, we can see here Default mock response
also created.
Before going to next step, we need to prepare the Input and
output test data. We need input data to feed the request xml and same we need
output data to configure the mock response. Below is sample test date I have
prepared for this post and it look like below,
Now we need to write some groovy script to configure the
Mock Response to do this, follow the steps.
Go to “GetGeoIP” request in Mock Service open it by right
click or double click on it, Mock Service request editor opens, it will looks
like below,
Now in the above screen we can see Mock response, and
Interface and Operation name. In addition, in below pane we can see Dispatch
and value as “SEQUENCE”; this is use for passing value or configuring the mock
response. Now to configure mock response as per our predefined response values
we need to write groovy script, hence select Dispatch value as “SCRIPT”. Once
you selected Dispatch as “SCRIPT” and Default Response will be “Response 1”,
which is same as mock response, which created when we added our request to mock
services. Below is screenshot how it looks like,
As shown in above screenshot, in Script editor need to write
groovy script to configure the mock response. Below is the code to configure
the mock response xml.
Mock response has five fields looks like below,
Now write groovy script to pass value to these five fields
in mock response.
Now let us describe the groovy script, in simple steps I
will try to explain the script.
Step 1 :- Import all necessary packages the groovy, groovy
Utils and excel packages.
Step 2 :- Create objects groovyutil to read the response
xml. Using requestxmlholder read all the tags in the response xml.
Step 3 :- Read the excel file from the path, and by using
for loop condition we can iterate the excel file until its last row.
Step 4 :- Now assign each cell value to a variable.
Step 5 :- Set variable to response xml tag, the value is the
variable will set the by this statement.
Once script is ready save the project, and now add above
created variable to response xml tag as below,
In above screenshot we can see mapping of the variables to
respective xml tags in mock response xml.
Now we are done with mock response xml configuration
dynamically. The groovy script will assign new value every time when the mock
response when called by the services. With this, we will get different value in
response with this we can assume our service is working fine.
Now run the Test Suite to check request and response for
different input to different output. Import the excel file which we have
created above to Data Source, and map the fields to request xml.
Start the mock service on the host and port as configured
(Refer my previous blog to configure the mock service with host and port name http://lgsofttest.blogspot.no/2014/07/web-service-testing-using-mock-service.html).
Running mock service will look like below,
Below screenshot shows, the request xml is running on the
mock service (Mock Service Endpoint in address bar), and value configured from Data
source for request xml field.
Now open the Test Case and run the test case,
Once the test case running completed verify the request and response
xml, to validate the result.
Click on any of the request to check input data in request
xml and output data in response xml.
Request XML with Input data,
Response xml from Mock response which configured by Groovy
script,
Finally, we are done with mock service testing for our
request.
In my next post, I will describe another way of Dynamic mock
service.
That’s all Folks.
