黄瓜JVM:如何使用double作为输入值？

Question

对于我正在尝试编写的行为测试,我需要浮点输入.如何设置我的小黄瓜字符串以查找这些值？

Answer 1

简单(.+)应该工作

Given I have a floating point 1.2345 number

@Given("^I have a floating point (.+) number$")
public void I_have_a_floating_point_number(double arg) throws Throwable { 
    ... 
}

Answer 2

我自己的偏好是在点的两侧指定数字,例如......

@Given("^the floating point value of (\\d+.\\d+)$")
public void theFloatingPointValueOf(double arg) {
    // assert something
}

当你提到浮点输入复数时,我可能会处理多个输入,其轮廓如...

Scenario Outline: handling lots of floating point inputs
    Given the floating point value of <floatingPoint>
    When something happens
    Then some outcome

    Examples:
        | floatingPoint |
        | 2.0           |
        | 2.4           |
        | 5.8           |
        | 3.2           |

它将为每个浮点输入运行一个场景
