英文:
Cucumber doesn't allow invalid enums after update from info.cukes to io.cucumber
问题
# 测试定义的功能文件
功能：解析枚举
场景：使用空字符串解析枚举
假设 我正在解析枚举“”
//步骤定义代码
@假设("^我正在解析枚举\"(.*?)\"$")
public void i_m_parsing_enum(MyEnum arg1) throws Throwable {
System.out.println(arg1); // 应该打印null，但在库升级后会抛出异常
}
//简单的枚举
public enum MyEnum {
abc, def
}
英文:
I'm migrating cucumber from old version from package info.cukes to latest io.cucumber. I noticed that old version allows invalid enum values as test arguments and returns null but latest version throws exception io.cucumber.core.exception.CucumberException: Could not convert arguments for step...
How can I keep old behaviour in my tests after migration? Below example code to reproduce error.
# feature file with test definition
Feature: Parsing enums
Scenario: Parse enum using empty string
Given I'm parsing enum ""
//Step definition code
@Given("^I'm parsing enum \"(.*?)\"$")
public void i_m_parsing_enum(MyEnum arg1) throws Throwable {
System.out.println(arg1); // should print null but throws exception after library upgrade
}
//Simple enum
public enum MyEnumo {
abc, def
}

以下是您要的翻译内容：
根据 @luis-iñesta 的评论，我使用 @ParameterType 注解编写了简单的 try-catch：
@ParameterType("[a-z]*")
public MyEnum myEnum(String name) {
try {
return MyEnum.valueOf(name);
} catch (IllegalArgumentException e){
return null;
}
}
@Given("I'm parsing enum \"{myEnum}\"")
public void i_m_parsing_enum(MyEnum arg1) throws Throwable {
System.out.println(arg1);
}
在这种情况下可以工作，但我仍然想知道是否有某个开关或参数可以保留旧的 Cucumber 行为。
英文:
Following @luis-iñesta comment I wrote simple try-catch using @ParameterType annotation:
@ParameterType("[a-z]*")
public MyEnum myEnum(String name) {
try {
return MyEnum.valueOf(name);
} catch (IllegalArgumentException e){
return null;
}
}
@Given("I'm parsing enum \"{myEnum}\"")
public void i_m_parsing_enum(MyEnumo arg1) throws Throwable {
System.out.println(arg1);
}
Works in this one case but I still wonder if there is some switch or parameter to keep old cucumber behaviour.
