问题描述
我有一组为Cucumber-JVM编写的验收测试。为了减少反馈时间，我想并行运行场景（一个特性）。
I have a set of acceptance tests written for the Cucumber-JVM. In order to reduce the feedback time I would like to run the scenarios (of a feature) in parallel. How do I do that in the simplest and most convenient way?
（我更喜欢能够在Java代码中表达这一点，作为一个普通的JUnit测试/运行器，也就是说，我不想使用maven-surefire或maven-failsafe插件来解决这个问题，后者需要（？）twiddling和合并Cucumber报告。）
(I would prefer to be able to express this in Java code, as a regular JUnit test/runner, i.e. I would prefer not to resort to some workaround using the maven-surefire or maven-failsafe plugin which would require(?) twiddling and merging of the Cucumber reports afterwards.)
推荐答案
由于cucumber-jvm包的性质，测试并行化暂时受到限制。有未来改变API（gherkin3，cucumber-jvm v2）的暂定计划，但没有什么可用于完全并行化现在在cucumber-jvm。
Due to the nature of the cucumber-jvm package, test parallelization is limited for the time being. There are tentative plans for the future to change the API (gherkin3, cucumber-jvm v2), but nothing is available for full parallelization now on the cucumber-jvm.
还有一种方法可以在cucumber-jvm上实现一定程度的并行性。 Zucchini包（）可以通过提供上下文级别并行性，如果您必须针对Android / iOS / Chrome /等运行一系列测试，则可以帮助您将测试结果合并到单个报告中。
There is still a way to attain a degree of parallelism on the cucumber-jvm. The Zucchini package (https://github.com/Comcast/Zucchini) can help by providing context-level parallelism, which could help if you have to run a battery of tests against Android / iOS / Chrome / etc. Test results are then merged into a single report.
要开始使用Zucchini，创建一个扩展 AbstractZucchiniTest 的新测试类，并标记为 @CucumberOptions 和 ZucchiniOutput 。然后该类应该实现 List< TestContext>
To start using Zucchini, create a new test class that extends AbstractZucchiniTest and is tagged with @CucumberOptions and ZucchiniOutput. The class should then implement the List<TestContext> getTestContexts() method that returns a list of your specialized contexts.
Zucchini还提供了其他功能，例如跨上下文屏障同步和聚合测试输出到HTML报告中。如果你已经有黄瓜测试，没有太多的参与升级到西葫芦测试。
Zucchini also provides other features such as cross-context barrier synchronization and aggregated test output into an HTML report. If you already have cucumber tests, there isn't much involved in upgrading them to Zucchini tests.
