我正在尝试为Cucumber的Java8方言设置示例项目。我的问题是,我无法运行它。我总是得到以下一系列异常:
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.068 sec <<< FAILURE! - in soy.wimmer.CucumberIT
Feature: Cucumber with Java8 Time elapsed: 0.051 sec <<< ERROR!

Results :
Tests in error:
Failed to instantiate class soy.wimmer.CucumberStepdefs

我不知道为什么会出现这个错误,也不知道该如何修复它。
我把所有东西都打包在一个Maven项目中。布局如下:
./src/test/java/soy/wimmer/CucumberIT.java
./src/test/java/soy/wimmer/CucumberStepdefs.java
./src/test/resources/cucumber/cucumber-java8.feature
./pom.xml
我在pom.xml中包含的依赖项如下:
<dependencies>
<dependency>
<groupId>info.cukes</groupId>
<artifactId>cucumber-java8</artifactId>
<version>1.2.3</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>info.cukes</groupId>
<artifactId>cucumber-junit</artifactId>
<version>1.2.3</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
</dependencies>
此外pom.xml只加载编译器和failsafe插件。
CucumberIT.java的定义:
package soy.wimmer;
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
import org.junit.runner.RunWith;
@RunWith(Cucumber.class)
@CucumberOptions(features = "classpath:cucumber")
public class CucumberIT {
}
我的特性定义:
Feature: Cucumber with Java8
As a developer
I want to use Cucumber-java8
So that I have nicer step definitions
Scenario: Let's try it
Given I have some dummy code
When I try to test it
Then it should work with cucumber-java8
这是我的步骤定义:
package soy.wimmer;
import cucumber.api.PendingException;
import cucumber.api.java8.En;
public class CucumberStepdefs implements En {
public CucumberStepdefs() {
Given("^I have some dummy code$", () -> {
// Write code here that turns the phrase above into concrete actions
throw new PendingException();
});
When("^I try to test it$", () -> {
// Write code here that turns the phrase above into concrete actions
throw new PendingException();
});
Then("^it should work with cucumber-java(\\d+)$", (Integer arg1) -> {
// Write code here that turns the phrase above into concrete actions
throw new PendingException();
});
}
}
有没有想法,我在这里做错了什么?
sun.reflect.ConstantPool
,这是引起兼容性问题的一种方法,但情况变得更糟了,看看有问题的代码行。糟透了。怎么可能认为常量池的任何一个随意位置(大小-2)包含某个特定信息呢?那高度依赖编译器,即使使用相同的编译器也不能保证这些项目的任何特定顺序。 - Holger
