测试目标类如下：

package cn.outofmemory.junit;

public class TestTarget {

/**

* 移除正则表达式中需要转义的字符

* @param w word

* @return 移除正则表达式中需要转义的字符

* @author yukaizhao

* @date 2013-2-19

*/

private static String convert4Regex(String w) {

if (w == null) {

return null;

}

String[] convertedChars = {"\",".","+","*","(",")","{","}","[","]","?","/","^","$","|"};

for (String c : convertedChars) {

w = w.replace(c, "\" + c);

}

return w;

}

}

测试方法：

@Test

public void testConvert4Regex() throws Exception {

String input = "A+";

String expected = "A\+";

Method targetMethod = TestTarget.class.getDeclaredMethod("convert4Regex", String.class);

targetMethod.setAccessible(true);

Object actual = targetMethod.invoke(TestTarget.class, new Object[]{input});

assertEquals(expected,actual);

}
