1. 在Maven中配置测试插件surefire
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
</plugin>
2. 默认被执行的测试
默认情况下，surefire会执行文件名以Test开头或结尾的测试用例，或者是以TestCase结尾的测试用例。
"**/Test*.java" - includes all of its subdirectories and all java filenames that start with "Test". "**/*Test.java" - includes all of its subdirectories and all java filenames that end with "Test". "**/*TestCase.java" - includes all of its subdirectories and all java filenames that end with "TestCase".</span>
3. 跳过测试 Skipping Tests
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<span style="color:#009900;"> <configuration>
<skipTests>true</skipTests>
</configuration></span>
</plugin>
</plugins>
</build>
补充：如果使用Junit或者TestNG也可以直接在当前测试方法上加注解@Ignore忽略，这是加了该注解的也都会被skip
4. 排除测试 Exclusions （Junit & TestNG 通用）
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<configuration>
<span style="color:#009900;"> <excludes>
<exclude>**/TestCircle.java</exclude>
<exclude>**/TestSquare.java</exclude>
</excludes></span>
</configuration>
</plugin>
</plugins>
</build>
5. 仅执行一个/一类测试(repeat) Running a Single Test （Junit & TestNG 通用）
在开发过程中配置命令：
mvn -Dtest=TestCircle test test表示当前测试方法所在的测试类，不需要扩展名 The value for the test parameter is the name of the test class
mvn -Dtest=TestCi*le test *表示任何
mvn -Dtest=TestSquare,TestCi*le test 如果测试类没有使用规范的命名，可以显示的直接指定测试方法的名称
Running a set of methods in a Single Test Class With version 2.7.3, you can run only n tests in a single Test Class. NOTE : it's supported for junit 4.x and TestNG. You must use the following syntax mvn -Dtest=TestCircle#mytest test You can use patterns too mvn -Dtest=TestCircle#test* test As of surefire 2.12.1, you can select multiple methods (JUnit4X only at this time, patches welcome) mvn -Dtest=TestCircle#testOne+testTwo test
6. 如何使用TestNG
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.3.1</version>
<scope>test</scope>
</dependency>
If using an older version of TestNG (<= 5.11)
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>5.11</version>
<scope>test</scope>
<span style="color:#009900;"> <classifier>jdk15</classifier></span>
</dependency>
默认会执行的测试用例：*Test.java7. 如何使用TestNG的 suite
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<configuration>
<span style="color:#009900;"><suiteXmlFiles>
<suiteXmlFile>testng.xml</suiteXmlFile>
</suiteXmlFiles></span>
</configuration>
</plugin>注意：
This configuration will override the includes and excludes patterns and run all tests in the suite files.

8. 执行群组测试 execute one or more specific groups （Junit & TestNG 通用）
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<configuration>
<span style="color:#009900;"> <groups>functest,perftest</groups></span>
</configuration>
</plugin>
9. 多线程的运行测试用例 Running tests in parallel （Junit & TestNG 通用）
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<configuration>
<span style="color:#009900;"><parallel>methods</parallel>
<threadCount>10</threadCount></span>
</configuration>
</plugin>
10. 如何使用Junit Using JUnit
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.8.1</version>
<scope>test</scope>
</dependency>
11. 如何使用Junit Category Using JUnit Categories
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.11</version>
<configuration>
<span style="color:#009900;"> <strong><groups>com.mycompany.SlowTests</groups></strong></span>
</configuration>
</plugin>
仅有带该注解的测试 或者 是当前注解 类/接口的 子类 会被执行，
This will execute only those tests annotated with the@Category(com.mycompany.SlowTests.class)annotation and those tests annotated with@Category(com.mycompany.SlowerTests.class)if class/interfaceSlowerTestsis subclass ofSlowTests:
public interface SlowTests{}
public interface SlowerTests extends SlowTests{}
------------------------------------------------------------------------------------------------
public class AppTest {
@Test
@Category(com.mycompany.SlowTests.class)
public void testSlow() {
System.out.println("slow");
}
@Test
@Category(com.mycompany.SlowerTests.class)
public void testSlower() {
System.out.println("slower");
}
@Test
@Category(com.cmycompany.FastTests.class)
public void testSlow() {
System.out.println("fast");
}
}参考：
Junit的@Category详解
12. 如何debug TestCases
mvnDebug -DforkCount=0 test dubug非fork的测试 在debug的需求时，还是使用Eclipse最方便
13. 使用系统属性 Using System Properties
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<configuration>
<span style="color:#009900;"><systemPropertyVariables>
<propertyName>propertyValue</propertyName>
<buildDirectory>${project.build.directory}</buildDirectory>
[...]
</systemPropertyVariables></span>
</configuration>
</plugin>
</plugins>
</build>
14. 选择surefire provider
surefire 默认会根据工程的classpath中已有的Junit|TestNG的版本来选择 test-framework provider，我们也可以手动的选择和覆盖当前的provider
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<span style="color:#009900;"> <artifactId>surefire-junit47</artifactId></span>
<version>2.17</version>
</dependency>
</dependencies>
</plugin>
目前已经提供的provider有surefire-junit3, surefire-junit4, surefire-junit47 and surefire-testng
参考：http://mvnrepository.com/artifact/org.apache.maven.surefire
注意：选择手动指定provider时，不要忘记安装test framework
