Running single test class or group with Surefire and TestNG
提问by Slartibartfast
I want to run single test class from command line using Maven and TestNG
我想使用 Maven 和 TestNG 从命令行运行单个测试类
Things that doesn't work:
不起作用的事情：
mvn -Dtest=ClassName test
I have defined groups in pom.xml, and this class isn't in one of those groups. So it got excluded on those grounds.
我在 pom.xml 中定义了组，而这个类不在这些组之一中。所以它被排除在这些理由之外。
mvn -Dgroups=skipped-group test
mvn -Dsurefire.groups=skipped-group test
when config is
当配置是
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.7.1</version>
<configuration>
<groups>functest</groups>
</configuration>
</plugin>
Parameters work fine in there are no groups defined in pom.xml.
参数工作正常，因为 pom.xml 中没有定义组。
Similarly, when surefire is configured with
同样，当surefire配置为
<configuration>
<includes>
<include>**/*UnitTest.java</include>
</includes>
</configuration>
I can add another test with -Dtestparameter, but cannot add group. In any combination, I can narrow down tests to be executed with groups, but not expand them.
我可以用-Dtest参数添加另一个测试，但不能添加组。在任何组合中，我可以缩小要与组一起执行的测试的范围，但不能扩展它们。
What's wrong with my configuration? Is there a way to run a single test or group outside of those defined in pom.xml?
我的配置有什么问题？有没有办法在 pom.xml 中定义的测试或组之外运行单个测试或组？
Tried on Ubuntu 10.04 with Maven 2.2.1, TestNG 5.14.6 and Surefire 2.7.1
在 Ubuntu 10.04 上尝试使用 Maven 2.2.1、TestNG 5.14.6 和 Surefire 2.7.1

As I've explained in question, any mention of groups either in pom.xml or on command line resulted in reduction of executed tests count. Only way I've managed to avoid this is by using mavens profiles like this:
正如我在问题中所解释的，在 pom.xml 或命令行中提及组会导致执行测试计数减少。我设法避免这种情况的唯一方法是使用这样的 mavens 配置文件：
<profiles>
<profile>
<id>test-slow</id>
<build>
<plugins>
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<groups>slow</groups>
</configuration>
</plugin>
</plugins>
</build>
</profile>
</profiles>
and then running tests with
然后运行测试
mvn -P test-slow test

I didn't test with TestNG 5.12.1 but I can say that running a single test using the testparameter andtests from groups using the groupsparameter works with TestNG 5.14.2 (and surefire 2.6) (groupsdoesn't work in TestNG 5.14)
我没有使用TestNG 5.12.1，但我可以说，通过运行一个测试test参数，并使用该组测试groups参数作品使用TestNG 5.14.2（和神火2.6）（groups不工作在TestNG的5.14）
Here is the pom.xmlI'm using:
这是pom.xml我正在使用的：

With a simple AppTestas follow:
简单AppTest如下：
import org.testng.annotations.*;
public class AppTest {
@BeforeClass
public void setUp() {
// code that will be invoked when this test is instantiated
}
@Test(groups = { "fast" })
public void aFastTest() {
System.out.println("Fast test");
}
@Test(groups = { "slow" })
public void aSlowTest() {
System.out.println("Slow test");
}
}
Both
两个都
$ mvn test -Dtest=AppTest
and
和
$ mvn test -Dgroups=slow
produce the expected result.
产生预期的结果。

I would suggest to try something like
我建议尝试类似的东西
mvn test -Dincludes=rs/magrathea/TestClassName
although I haven't tested this myself.
虽然我自己没有测试过。

In order to run a single test you need the following from official documentation
mvn -Dtest=MyFirstTest test
mvn -Dtest=MyFirstTest 测试
or
或者
mvn -Dtest=MyFirstTest,MySecondTest test
mvn -Dtest=MyFirstTest,MySecondTest 测试
This is tested (and working) on maven 3.
这是在 maven 3 上测试（和工作）的。
Then you can avoid using the profiles. I had the same problem as I needed to run load test in isolation and using profiler in parallel to get the real figures.
然后您可以避免使用配置文件。我遇到了同样的问题，因为我需要单独运行负载测试并并行使用分析器来获取真实数据。
Note: Not sure why but make sure that the switches come before the phase i.e. "-Dtest=MyFirstTest" before "test" otherwise it is not working (Mac OSX)
注意：不知道为什么，但要确保开关出现在阶段之前，即“-Dtest=MyFirstTest”在“test”之前，否则它不起作用（Mac OSX）
