Maven测试失败：找不到符号

我正在尝试使用Maven设置测试。尝试运行命令“ mvn test”时出现以下错误：

[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] /Users/dso/Documents/Eclipse-Workspace/MavenSample/src/test/java/MavenSample/MavenSample/RestAPITest.java:[3,30] cannot find symbol
  symbol:   class Test
  location: package org.testng.annotations

mvn clean和mvn compile都适合我，没有错误。如果只是像testng一样运行，则测试本身也可以正常运行。mvn测试完成后，测试失败。以下是我的pom.xml文件的代码。
