Dataset testing runs a test plan in parallel with several datasets.

For example, we want to run the following test plan (saved in “finding-fastest-routes.feature”) in order to test :

1. the fastest route to London
2. the shortest route to Rome

Feature: Finding fastest routes

  Scenario: no run : Finding routes to "Paris"
    When I enter "Paris" into "Destination"
    And I click on "Go"

  Scenario: Finding the fastest route to "London"
    When I find routes to "London"
    And I select "Fastest route" in "Found routes"

We will create two datasets for the two cases.

For convenience, a dataset model for our test plan can be generate by executing the following command (described in “yascribe client command line“) :

java -jar yascribe-jcl.jar --gen-dataset finding-fastest-routes.feature

The generated dataset model is a .yaml file named “finding-fastest-routes.dataset.xxx.yaml” :

scribe: "Finding fastest routes"
scenarios:
  Finding the fastest route to "London":
    variables:
      London: "London"
      Destination: "Destination"
      Go: "Go"
      Fastest route: "Fastest route"
      Found routes: "Found routes" 

Duplicate the datset model file to two new files :

1. finding-fastest-routes.dataset.1.yaml
2. finding-fastest-routes.dataset.2.yaml

Modify the second file by replacing :

• “London” by “Rome”
• “Fastest route” by “Shortest route”

scribe: "Finding fastest routes"
scenarios:
  Finding the fastest route to "London":
    variables:
      London: "Rome"
      Destination: "Destination"
      Go: "Go"
      Fastest route: "Shortest route"
      Found routes: "Found routes" 

Launch the test plan. The test plan will be run in parallel with the two datasets.
