Question

我想要相同的Gherkin句子（有参数和没有参数）：

Gherkin与参数：

When a 'notify' message is sent to the green box with the properties.
 |type|message|
 |error|The error message|

没有参数的小黄瓜：

When a 'notify' message is sent to the green box with the properties.

Java（黄瓜）：

@When("^a '(.*)' message is sent to the green box with the properties.$")
public void hello(String name, List<GherkinCondition> conditions) {
    ...
}

我有一个错误，因为java方法是用2个参数声明的，在“没有参数”的情况下，我只有一个。

堆栈跟踪：

cucumber.runtime.CucumberException: Arity mismatch: Step Definition 'steps.CommonSteps.hello(String,GherkinCondition>) in file:/C:/workspace/xxxxx/java/target/classes/' with pattern [^a '(.*)' message is sent to the green box with the properties.$] is declared with 2 parameters. However, the gherkin step has 1 arguments [notify].

Answer 1

黄瓜步骤定义不支持可选参数。

您可以编写两个不同的步骤定义，也可以为第二个案例提供一个空的数据表。

When a 'notify' message is sent to the green box with the properties.
 |type|message|

甚至

When a 'notify' message is sent to the green box with the properties.
     |||

我创建了一个PR来解决此问题：https://github.com/cucumber/cucumber-jvm/pull/1056

小黄瓜脚本测试：

@hello 
Feature: hello (Function to validate the environment.) 

    Scenario Outline: Function to validate the environment.
        Given me a hello, please. Best Regards '<author>'.
        Given me a hello, please. Best Regards '<author>'.
            |key|expected|actual|
        Given me a hello, please. Best Regards '<author>'.
            |key|expected|actual|
            |zip|35000|<zip>|
            |city|Rennes|<city>|

        Given me a bye, please. Best Regards '<author>'.
        Given me a bye, please. Best Regards '<author>'.
            |zip|<zip>|
            |city|<city>|

        Given me a cat, please. Best Regards '<author>'.

    Examples:
    #Begin Examples#
    |author|zip|city|
    |Jenkins Q1|35000|Rennes|
    |Jenkins Q2|35000|Rennes|
    #End Examples#

Java黄瓜代码：

    @Given("^me a hello, please. Best Regards '(.*)'.$")
    public void hello(String name, List<GherkinCondition> conditions) {
        int i = 0;
        for (GherkinCondition gherkinCondition : conditions) {
            i++;
            logger.info(String.format("  expected contition N°%d=%s", i, gherkinCondition.getExpected()));
            logger.info(String.format("  actual   contition N°%d=%s", i, gherkinCondition.getActual()));
        }
        logger.info("Hello " + name + "!");
    }

    @Given("^me a cat, please. Best Regards '(.*)'.$")
    public void hello(String name) {
        logger.info("Take my cat " + name + "!");
    }

    @Given("^me a bye, please. Best Regards '(.*)'.$")
    public void bye(String name, Map<String, String> params) {
        int i = 0;
        for (Map.Entry<String, String> entry : params.entrySet()) {
            i++;
            logger.info(String.format("  Key N°%d: %s   Value:%s", i, entry.getKey(), entry.getValue()));
        }
        logger.info("Bye " + name + "!");
    }

Answer 3

这对我有用。我可以通过IND或USA。注意：如果您没有通过任何IND，USA，这将无效。

@When("^I search (.*) (IND|USA)? in Database$")
public void searchInDatabase(String name, String country){
    if(country.equals("IND"))
        dbObj.searchDatabase(name, true);
    else if(country.equals("USA"))
        dbObj.searchDatabase(name, false);
    else
        dbObj.searchDatabase(name, true); 
}

Answer 4

我得到了问题的答案： -

@When（＆＃34; ^我在（IND | USA）搜索（。*）？数据库$＆＃34;）

我正在寻找美国或IND的可选参数。以上行解决我的问题。（和|

之后需要空格

Answer 5

我正在这样做：

@Then("^Something is (not )?counted$")
public void somethingCounted(String optional) {
    //
}

正则表达式同时匹配“已计算在内”和“未计算在内”

对于第一种情况，您将获得“ not”值，对于第二种情况，您将获得null。
