How to make multiple queries with different data in Grails integration tests

Question

I am writing a Grails 2.2.1 integration test using the Spock plugin in which I am trying to send two data sets to the same controller endpoint:

when: "The user adds this product to the inventory" def postData = [productId: 123] controller.request.JSON = postData controller.addToInventory() and: "Then they add another" def secondPostData = [productId: 456] controller.request.JSON = secondPostData controller.addToInventory() then: "The size of the inventory should be 2" new JSONObject( controller.response.contentAsString ).inventorySize == 2 

The problem that I see is that the same JSON is sent to addToInventory () for both requests.

https://stackoverflow.com/questions/692256/... suggests invoking controller.request.reset (), but this did not work (There is no method signature: org.codehaus.groovy.grails.plugins.testing.GrailsMockHttpServletRequest.reset ()).

Am I trying to do this?

Answer 1

Where: can be used to perform data-driven testing as part of testing testing. Try using the following example:

 when: "The user adds this product to the inventory" controller.params.JSON = [productId:productId] controller.addToInventory() then: "The size of the inventory should be 2" new JSONObject( controller.response.contentAsString ).inventorySize == 2 where: ID|productId 1|123 2|456 

Hope this helps !!!

There is another way. Insert:

 GrailsWebUtil.bindMockWebRequest() 

at the beginning of your second test. This will effectively create a new ServletContext, a new MockHttpServletRequest, a new MockHttpServletResponse, and then bind all three to the current thread.

While Anuj us correct that where clauses should be used to keep the tests clean, there are times when more than one query needs to be run in a test. In my case, I wanted to check that when he received 2 repeated POSTS, the second was rejected correctly.

I found that resetting the response did what I needed:

 controller.response.reset() 

To cancel the response.
