我有一个黄瓜项目,我想在项目中获取所有标签,以便能够选择它们作为参数。
我发现了这个question,黄瓜可以选择获取标签,但是我发现它不再起作用了,然后我找到了另外一个question,在那里我需要一个自定义格式化程序我的标签,但它是用于ruby的,而Java需要它,因此我找到了如何创建自定义格式程序的article,但是我发现这适用于cukes版本,并且我正在使用一世。
因此,我在Cucumber包中进行了搜索,并从Cucumber.runtime.formatter包中的JSONFormatter副本创建了一个自定义格式器,这是我的代码:
import cucumber.api.TestCase;
import cucumber.api.event.*;
import cucumber.api.formatter.Formatter;
import cucumber.api.formatter.NiceAppendable;
import gherkin.deps.com.google.gson.Gson;
import gherkin.deps.com.google.gson.GsonBuilder;
import gherkin.pickles.PickleTag;
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
public class TagsFormatter implements Formatter {
private String currentFeatureFile;
private final Gson gson = new GsonBuilder().setPrettyPrinting().create();
private final NiceAppendable out;
private List<String> tags = new ArrayList<>();
private EventHandler<TestCaseStarted> caseStartedHandler = this::handleTestCaseStarted;
private EventHandler<TestRunFinished> runFinishedHandler = event -> finishReport();
public TagsFormatter(Appendable out) {
this.out = new NiceAppendable(out);
}
@Override
public void setEventPublisher(EventPublisher publisher) {
publisher.registerHandlerFor(TestCaseStarted.class, caseStartedHandler);
publisher.registerHandlerFor(TestRunFinished.class, runFinishedHandler);
}
private void handleTestCaseStarted(TestCaseStarted event) {
if (currentFeatureFile == null || !currentFeatureFile.equals(event.testCase.getUri())) {
currentFeatureFile = event.testCase.getUri();
collectTags(event.testCase);
}
}
private void finishReport() {
out.append(gson.toJson(tags));
out.close();
}
private void collectTags(TestCase testCase) {
testCase.getTags();
tags.addAll(testCase.getTags()
.stream()
.map(PickleTag::getName)
.collect(Collectors.toList()));
}
}
我复制了在项目内部的lib文件夹中运行黄瓜所需的库,并尝试使用这样的格式化程序来运行它:
java -cp .\lib\cucumber-core-2.4.0.jar;.\lib\gherkin-5.0.0.jar;.\lib\cucumber-java-2.4.0.jar;.\lib\cucumber-jvm-deps-1.0.6.jar cucumber.api.cli.Main -p "com.myproject.formatters.TagsFormatter:tags.txt"
但是我正在获取一个类未找到异常:
λ java -cp .\lib\cucumber-core-2.4.0.jar;.\lib\gherkin-5.0.0.jar;.\lib\cucumber-java-2.4.0.jar;.\lib\cucumber-jvm-deps-1.0.6.jar cucumber.api.cli.Main -p "com.myproject.formatters.TagsFormatter:tags.txt"

那么,如何以可识别的方式创建此格式化程序?还是至少从控制台获得了黄瓜的标签列表?
谢谢

仅查看您的代码,我认为它没有任何问题。但是,您的命令似乎没有在类路径中包含TagsFormatter
的编译版本。
如果您的编译源位于.\bin\
中,请确保包括该文件夹,即:
java -cp .\lib\cucumber-core-2.4.0.jar;.\lib\gherkin-5.0.0.jar;.\lib\cucumber-java-2.4.0.jar;.\lib\cucumber-jvm-deps-1.0.6.jar;.\bin\* cucumber.api.cli.Main -p "com.myproject.formatters.TagsFormatter:tags.txt"
