比较文本文件w / Junit [英] Comparing text files w/ Junit

问题描述

我比较junit中的文本文件：

I am comparing text files in junit using:

  public static void assertReaders(BufferedReader expected,
          BufferedReader actual) throws IOException {
    String line;
    while ((line = expected.readLine()) != null) {
      assertEquals(line, actual.readLine());
    }

    assertNull("Actual had more lines then the expected.", actual.readLine());
    assertNull("Expected had more lines then the actual.", expected.readLine());
  }

这是比较文本文件的好方法吗？什么是首选？

Is this a good way to compare text files? What is preferred?

推荐答案

junit-addons 对此有很好的支持： FileAssert

junit-addons has nice support for it: FileAssert

它会给你例外：

junitx.framework.ComparisonFailure: aa Line [3] expected: [b] but was:[a]
