title: How to get the file name from .properties file in java JUnit?
body: <p>I have 8 test cases in which each test case makes use of a different file. How do I get the specific file from the .properties file which contains the path for the file(s). Some of the test cases are as shown below:</p>
  
  <pre><code>@Test
      public void testIfColDataReadIsCorrect() throws FileNotFoundException{
  
          obj.readExcelToGetData("D:/ExcelTestFiles/testExcelWithAllColData.xlsx");
          rowObj= obj.getRowRecord();
          assertEquals(rowObj.getName(), TEST_NAME);
          assertEquals(rowObj.getId(), TEST_id);
          assertEquals(rowObj.getDate(), TEST_DATE);
          assertEquals(rowObj.getMessage(), TEST_MSG);
          assertEquals(rowObj.getPage(), TEST_PAGE);
          assertEquals(rowObj.getType(), TEST_TYPE);
          assertEquals(rowObj.getLikeCount(),TEST_LIKECOUNT);
          assertEquals(rowObj.getShareCount(), TEST_SHARECOUNT);
          assertEquals(rowObj.getCommentCount(), TEST_COMMENTCOUNT);
      }
      @Test
      public void testWhenNameColDoesNotExists() throws FileNotFoundException{
          //FacebookDataExtraction obj= new FacebookDataExtraction();
          //FacebookFields rowObj=new FacebookFields();
          obj.readExcelToGetData("D:/ExcelTestFiles/testExcelWithNoNameCol.xlsx");
          rowObj= obj.getRowRecord();
          assertEquals(rowObj.getName(), null);
          assertEquals(rowObj.getId(), TEST_id);
          assertEquals(rowObj.getDate(), TEST_DATE);
          assertEquals(rowObj.getMessage(), TEST_MSG);
          assertEquals(rowObj.getPage(), TEST_PAGE);
          assertEquals(rowObj.getType(), TEST_TYPE);
          assertEquals(rowObj.getLikeCount(),TEST_LIKECOUNT);
          assertEquals(rowObj.getShareCount(), TEST_SHARECOUNT);
          assertEquals(rowObj.getCommentCount(), TEST_COMMENTCOUNT);
  
      }

  <p>I think this is not the best practice to directly input the file path to the method <code>readExcelToGetData()</code>. After going through certain posts I found that the files can the put in <code>.properties</code> file and can be read from it. How do I get the specific file path in each test case?</p>
