我想出了另一个解决方案，使用 maven 和 cucumber 重新运行刚刚失败的测试。
1) 使用RunNotifier 记录测试失败
public class RerunningCucumber extends Cucumber {
private final String className;
@SuppressWarnings("rawtypes")
public RerunningCucumber(Class clazz) throws InitializationError, IOException {
super(clazz);
className = clazz.getSimpleName();
}
@Override
public void run(RunNotifier notifier) {
notifier.addListener(new RunListener(){
public void testFailure(Failure failure) throws Exception {
Throwable error = failure.getException();
if (error instanceof AssertionError){
//Nothing. This is a normal failure. Continue
return;
}
//No! A wild exception has appeared!
//Let's run this test again.
RerunningCucumber.addFile(className);
}
});
super.run(notifier);
}
private static final String filename = "target/rerun.properties";
private static final Set<String> addedClasses = new HashSet<String>();
public static synchronized void addFile(String className) throws IOException{
//First find the file
if (addedClasses.contains(className)){
return;
}
File file = new File(filename);
if (!file.exists()){
//Need to create the file
PrintWriter writer = new PrintWriter(file, "UTF-8");
writer.print("retryclasses=**/"+className+".class");
writer.close();
}
else {
PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(file, true)));
out.print(",**/"+className+".class");
out.close();
}
addedClasses.add(className);
}
}
2) 使用自定义类作为黄瓜测试的运行器。
这将运行测试，并且每当出现故障时，将失败的类输出到文件中。诀窍是保持功能简短并创建大量测试类以避免重复测试。
@RunWith(RerunningCucumber.class)
@CucumberOptions(features = {"classpath:features/testFeature.feature}, format = {
"html:target/cucumber-html-report/testFeature.html",
"json:target/cucumber-json-report/testFeature.json"},
tags = {"@testFeature"})
public class RunTestFeature {
}
3) 将 Rerun 配置文件添加到 maven。
这做了三件事：1) 它将失败的类加载到内存中，2) 只清理失败的类属性文件，3) 只重新运行从属性文件加载的失败的测试：
<profile>
<id>retry</id>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>properties-maven-plugin</artifactId>
<version>1.0-alpha-2</version>
<executions>
<!-- Associate the read-project-properties goal with the initialize
phase, to read the properties file. -->
<execution>
<phase>pre-clean</phase>
<goals>
<goal>read-project-properties</goal>
</goals>
<configuration>
<files>
<file>target/rerun.properties</file>
</files>
</configuration>
</execution>
</executions>
</plugin>
<plugin>

<configuration>

<fileset>

<include>rerun.properties</include>

</filesets>

</goals>
<configuration>
<target>

</target>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<configuration>
<includes>
<include>${retryclasses}</include>
</includes>
<testFailureIgnore>true</testFailureIgnore>
</configuration>
<executions>
<execution>
<phase>test</phase>
<goals>
<goal>test</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
4) 用法
第一次试运行：
mvn clean test
下一个测试运行：
mvn clean test -Pretry
mvn clean test -Pretry
mvn clean test -Pretry
...
您可以根据需要重复多次，直到没有错误为止。
