Cucumber: Scenario Outline reusing examples table

问题

I have a few tests like below:

Scenario Outline: Add two numebrs
  Given two numbers <number_1> and <number_2>
  When I add them
  Then Result is <number_3>

  Examples:
    |number_1|number_2|number_3|
    |2       |3       |5       |
    |1       |2       |3       |

Scenario Outline: Update two numebrs
  Given two numbers <number_1> and <number_2>
  When I update them
  Then Result is <number_3>

  Examples:
    |number_1|number_2|number_3|
    |2       |3       |5       |
    |1       |2       |3       |

For each test I should add the same table Examples.

Is any way to extract this table to use the same one for all tests?

回答1:

The easiest solution that comes to my mind is combining both scenarios, extracting details to the examples table. So it would look like:

| number_1 | number_2 | operation | result |

You have another possibility.

Scenario: Add two numebrs
Given I have the matrix of numbers
When I add them
Then I would have the resulting vector.

Scenario: Update two numebrs
Given I have the matrix of numbers
When I update them
Then I would have the resulting vector.

Where "the matrix of numbers" and "the resulting vector" go to step defs file.

回答2:

You can use qaf-gherkin where you can move examples in external file and use it with one or more scenario. With qaf your feature file may look like below:

Scenario Outline: Add two numebrs
  Given two numbers <number_1> and <number_2>
  When I add them
  Then Result is <number_3>

  Examples::{'datafile':'resources/testdata.txt'}

Scenario Outline: Update two numebrs
  Given two numbers <number_1> and <number_2>
  When I update them
  Then Result is <number_3>
  Examples:{'datafile':'resources/testdata.txt'}

And your datafile will look like:

  #col.separator=|
  number_1|number_2|number_3
  2|3|5       
  1|2|3

Above is example of csv (charter separated values) data provider with | as seperator. You also can use different data providers to provide data from any of excel/xml/json/database.

EDIT: qaf-cucumber has BDD2 support with cucumber that can be used with Cumber 5.
