【问题描述】：
我正在使用 Junit 5 运行一组测试。 如果它们由 Maven 启动，它们可以正常工作，但我无法在 Eclipse 中正常运行它们。
显然问题是Eclipse没有正确考虑注解@CsvFileSource的参数。
测试：
@ParameterizedTest
@CsvFileSource(resources = INPUT_FILE_NAME, numLinesToSkip=1, delimiter=';')
public void testSpot(
String crossCcy,
@ConvertWith(LocalDateConverter.class) LocalDate date,
@ConvertWith(LocalDateConverter.class) LocalDate expectedSpot
) throws JFxLibException, IOException {
FxDateCalculator calculator = FxDateCalculator.newInstance(crossCcy);
LocalDate spotDate = calculator.getSpotDate(date);
Assertions.assertEquals(expectedSpot, spotDate, "Cross " + crossCcy + ", date=" + date + ",");
}
Mvn：
$ mvn test

我的 csv 输入有标题（但 Eclipse 不会跳过标题行）
cross;date;expected spot
EURUSD;09/12/2015;11/12/2015
EURUSD;04/12/2015;08/12/2015
我正在使用 Eclipse Oxygen： 版本：Oxygen.3a 版本 (4.7.3a) 内部版本号：20180405-1200
【问题讨论】：
-
INPUT_FILE_NAME是相对路径还是绝对路径？如果是相对的，请确保在启动配置中正确设置了 Working directory（在标签 Arguments 中）。 -
是相对路径，资源在classpath中。来自Javadoc：
The CSV classpath resources to use as the sources of arguments; must not be empty.实际上文件被找到并读取，我只是在读取参数时遇到异常 -
我明白了。
numLinesToSkip从 JUnit 5 开始就存在，因此可能的解释是您在 Java 构建路径中使用了 JUnit 5 的预发行版（因为问题是由 JUnit 代码引起的，而不是由 Eclipse 代码引起的）。不幸的是，您使用的是非常旧的 Eclipse 版本，没有 显示命令行 功能，这在这里会很有帮助。 -
谢谢@howlger，你是对的。我使用的是没有该参数的 Junit5 版本。实际上它是一个发布版本（5.0.0），但它不包含
numLinesToSkip -
太好了，在当前的 Javadoc 中有no Since at
numLinesToSkip，所以我错误地认为它已经被 JUnit 5.0 支持。总之，问题解决了。
