How to pass a context parameter value to a web test from MTM

Question

I have a test case with an associated automation (a webtest) and I need to run the same test case on different web servers. I have a context parameter in the webtest to hold the url (URL_VALUE)

I have no problems running the webtest from command line using MSTest.exe and initializing the environment variable using Test.URL_VALUE=<url value>

But now I need to do the same but using Test Manager instead, is there any way of using the test case parameters to accomplish this? Or any other way of passing values to a webtest?

Thanks in advance

Answer 1

You will need a physical or virtual environment to run automated tests from MTM http://msdn.microsoft.com/en-us/library/dd553270.aspx

You can then use environment variables in the same way on those machines as you described above.

Hi Anuj,

I have a physical environment to run the test cases, my doubt is how to set the environment variables in the test agent using Test Manager.

Should I execute a script before the automated test run which sets the env. variables? (i.e. using the test settings and a script that executes the shell commands to set the env. variables?)

Answer 3

Yes executing it as a Pre script in Test Settings would be a good idea.

Thanks,

Hi Anuj,

I tryed to set the environment variables in the pre script but it doesn't work (I'm using a batch file to set the env. variables.)

I view this in the qtsetup.bat file:

set URL_VALUE=https://sctest.test.int

But the context parameter URL_VALUE is empty when my web test executes.

I tryed this other syntax but it failed too:

set Test.URL_VALUE=https://sctest.test.int

What else can I try?

Thanks

Answer 5

Finally I wrote a web test plugin that runs before the web test (PreWebTest event).

It reads from a file deployed within the test settings and then inside the plug-in read from that file and set the context variables. (the downside is that I need to have a different test setting per web server)

Thanks

Your plugin sounds handy,   can we get hold of it?
