使用BDD（Squish）的多个I / O数据测试场景/以BDD格式的数据驱动测试

Question

Following is the sample project I am working on.

Scenario :Adder application to be tested in BDD.

Given Adder application is running When Two input values are given corresponding to which we get an output. Then Validate the output field.

I am, able to execute the test with a set of 2 input values.

Is it possible to execute the same scenario with the different set of input values.

Answer 1

Yes its possible. The solution is called Scenario Outline Fe

Scenario Outline: Adder application to be tested in BDD.
Given Adder application is running 
When <input_values> are given corresponding to which we get an output. 
Then Validate the <output> field.      

Examples:
| input_values | output  |
| foo          | bar     |
| new foo      | new bar |

Answer 2

If you want it for every scenario, use the OnScenarioStart hook...

You can also do this without a Scenario Outline, using table data:

Scenario: Adder application to be tested in BDD.
Given Adder application is running 
Then for each input value provided, verify the output value.
    | inputvalue | outputvalue |
    | foo | bar |
    | new foo | new bar |

You access the table in your step using the context.table object

Then("for each input value provided, verify the output value", function(context) {
    var table = context.table;

    // Skip initial row with column headers by starting at index 1
    for (var i = 1; i < table.length; ++i) {
        var inputValue = table[i][0];
        var outputValue = table[i][1];
        // make magic happen
    }
});
