Getting "Does not have a matching glue code" error for empty fields using Cucumber
提问by Ram
I'm new to Cucumber. I want to test two login scenarios:
我是黄瓜的新手。我想测试两个登录场景：
- With valid credentials where user should be able to login successfully
- With empty username and password where the user should not be able to login
- 使用有效凭据，用户应该能够成功登录
- 使用空的用户名和密码，用户应该无法登录
I have the following code for the above scenario:
对于上述场景，我有以下代码：
Scenario Outline: Test login with valid credentials
Given Open firefox and start application
When I enter "<username>" and "<password>"
Then User should be able to login successfully
Examples:
| username | password |
| ro | mech |
Scenario Outline: Test login with empty credentials
Given Open firefox and start application
When I enter "<username>" and "<password>" (this shows a warning)
Then User should be not able to login
Examples:
| username | password |
| | |
In the java file I have the following code:
在java文件中，我有以下代码：
@When("^I enter \"([^\"]*)\" and \"([^\"]*)\"$")
public void I_enter_and_(String username, String password) throws Throwable {
driver.findElement(By.id("ember629")).sendKeys(username);
driver.findElement(By.id("ember640")).sendKeys(password);
}
My question is scenario 2 shows a warning message:
我的问题是场景 2 显示了一条警告消息：
Step 'I enter "<username>" and "<password>"' does not have a matching glue code
Does this mean that for every scenario like valid, empty and invalid credentials I need to write a separate java function? Can't I use the same java function:
这是否意味着对于像有效、空和无效凭据这样的每个场景，我都需要编写一个单独的 java 函数？我不能使用相同的 java 函数：
public void I_enter_and_(String username, String password)
for all the scenarios? If I run the feature file I get this output:
对于所有场景？如果我运行功能文件，我会得到以下输出：
You can implement missing steps with the snippets below:
@When("^I enter \"([^\"]*)\" and \"([^\"]*)\"$")
public void i_enter_and(String arg1, String arg2) throws Throwable {
// Write code here that turns the phrase above into concrete actions
throw new PendingException();
}
Is there any way to reuse the java function I_enter_and_?
有没有办法重用java函数I_enter_and_？

First of all, if that's an actual copy/paste of your error, it looks like you have an extra space after I enterin your step. To be sure, just copy the automatically suggested step and use it instead of the current one.
首先，如果这是您的错误的实际复制/粘贴，那么I enter您的步骤之后似乎有一个额外的空间。可以肯定的是，只需复制自动建议的步骤并使用它而不是当前步骤。
Another thing is that tat does not make sense to use Scenario Outlineif you do not provide more than one example. It should look more like:
另一件事是，Scenario Outline如果您不提供多个示例，则使用 tat 没有意义。它应该看起来更像：
Scenario Outline: Test login with valid credentials
Given Open firefox and start application
When I enter "<username>" and "<password>"
Then User "<maybe>" be able to login successfully
Examples:
| username | password | maybe |
| ro | mech | shall |
| | | shall not |
