java - JUnit 无法找到我的类

Question

当我运行 JUnit 时，我收到一条错误消息，指出它无法找到我正在通过的测试。但是，因为该类位于我的工作目录中，而我的工作目录位于我的类路径中，所以我不确定为什么。谁能指出我正确的方向吗？

grader $  echo $JUNITPATH
/users5/cse/dfischer/lib/junit.jar:/users5/cse/dfischer/lib/hamcrest-core-1.3.jar:.

Tried java -cp $JUNITPATH org.junit.runner.JUnitCore TestCalculatorWithMethod without the .class at the end? – David Wallace

问题是传入 TestCalculatorWithMethod.class 而不是 TestCalculatorWithMethod。
