步骤定义无法识别

Question

我正在使用量角器和黄瓜进行e2e测试。 场景大纲如下：

Scenario Outline: Visit HomeScreen
Given I am on the homescreen
When I do nothing
Then I should see the element with id <elemid>    

Examples:
|elemid|
|scan-sample-image|
|how-to-run|
|navigation-button|

我对＆＃34;然后＆＃34;的步骤定义部分就像：

this.Then(/^I should see the element with id \<elemid\>$/, function(id){
//some code      
});

然而，当我打电话给量角器时，我看到了：

Scenario: Visit HomeScreen
V Given I am on the homescreen
V When I do nothing
? Then I should see the element with id scan-sample-image

Scenario: Visit HomeScreen
V Given I am on the homescreen
V When I do nothing
? Then I should see the element with id how-to-run

Scenario: Visit HomeScreen
V Given I am on the homescreen
V When I do nothing
? Then I should see the element with id navigation-button

＆＃34;然后＆＃34;没有被认可。 我的错误在哪里？

Answer 1

尚未认真使用cucumber，但您的Then定义不应该使用捕获组来使用此正则表达式：

/^I should see the element with id (.*?)$/

Answer 2

您的Gherkin语法不正确，dimond括号周围应该有引号

尝试更改以下行

Then I should see the element with id <elemid>    

到

Then I should see the element with id "<elemid>"    

然后生成步骤，它应该变成这样的东西，

this.Then(/^I should see the element with id (.*)$/, function(id){
   //some code      
});
